Beehive coke ovens were used to produce coke from coal, which was essential for industrial processes such as smelting of iron ore and melting and refining of steel. The ovens were so named because of their dome shape, which resembled a bee-hive.
To produce coke, coal was loaded into the ovens, which were heated to 1220°C (2228°F) by a fire beneath, controlled by air flow. The burning coal was raked and turned frequently by workers using hand rakes, transferring fresh coal to the fire, and pushing the partly burnt coal away from the fire to the side of the oven and eventually transferring it to the separate quenching chamber.
As the oven burned and the coal was heated, it created a flame via the pyrolization process, driving off atmospheric gases and volatiles. This process also converted the coal into coke while producing coke oven gas as a byproduct, which itself could be used as a fuel or to make tar and ammonium sulfate fertiliser.
When enough coke had been produced in the oven, the heat was extinguished and the door of the oven was knocked down. The coke was then quenched with water, which extinguished the fire and stopped the further production of coke oven gas.
The coke would be then loaded into rail cars or sent to a horizontal byre oven for additional processing.
Beehive coke ovens were essential for production of steel, as well as producing lighting fuel, tar, and even ammonium sulfate for agricultural use. However, these labor-intensive ovens were eventually replaced by the much more energy-efficient, higher output, and less labor-intensive byre ovens, finally marking the end of the use of beehive coke ovens.
How do you make a beehive pizza in the oven?
Making a beehive pizza in the oven is a fairly straightforward process and can be completed in just a few steps.
First, preheat your oven to 400 degrees F or whatever the temperature is indicated on your pizza crust or pizza dough package.
Next, prepare your pizza dough. Roll out the dough to the size of your pizza pan or stone. Place it onto the pan and cover the outer edge of the dough with olive oil or butter.
Third, spread your desired sauce onto your pizza dough. This could be anything from BBQ sauce, to traditional pizza sauce, to pesto.
Fourth, layer your cheese, meats, and/or vegetables onto your pizza. Make sure the toppings are spread evenly.
Fifth, take a spoon and scoop out dollops of the pizza dough inorder to create the “beehive” shape. Start from the center of the pizza and make small indentations all the way to the edge of the pizza dough.
Place the spoon back in the center and repeat the process until you have a beehive shaped design.
Lastly, bake your pizza in the preheated oven. Bake for 10 to 15 minutes or until the edges of the beehive have golden-brown spots. Once cooked, remove your pizza from the oven and let cool before serving. Enjoy!.
Is it better to bake or broil pizza?
The answer to the question whether it is better to bake or broil pizza depends on the desired outcome.
Baking is the classic and most popular choice for pizza and tends to produce even results with minimal effort. This is because the consistent, indirect heat of the oven radiates evenly and helps ensure the dough cooksAll successfully and the toppings are hot and bubbly.
Baking can vary in temperature as it typically burns hotter in the center of the oven and cooler at the sides, so it’s best to rotate your pizza and to adjust the cooking time and temperature if necessary.
Broiling, on the other hand, is a quick and easy technique that offers a different way to cook pizza. With this method, the heat is direct and intense. The top of your pizza will get much hotter than the bottom, making it great for someone who likes a crispy crust.
To broil pizza, you’ll need to position the rack of the oven so it’s just a few inches away from the broiling element. This being said, you’ll need to be much more vigilant during the cooking process and you may need to move your pizza around a few times during cooking to ensure it doesn’t burn.
In summary, it is a matter of personal preference as to whether you’d like to bake or broil pizza. If you are looking for consistent cooking and dishes, then baking is likely your best choice as it is a more reliable, indirect approach.
However, if you are a fan of a crispy crust and are looking for a quick cooking technique, then you may want to give broiling a try.
How long should you broil pizza?
The length of time you should broil pizza depends on several factors. Generally, you should broil a pizza for 5-10 minutes, checking it occasionally to make sure the cheese is melted, the crust is a golden-brown color, and the toppings are to your desired doneness.
However, the time can vary depending on the size and thickness of the pizza, the type and amount of toppings, and your oven’s power. Be sure to pay close attention to your pizza when broiling to avoid burning it!.
Can you cook frozen pizza on broil?
Yes, you can cook frozen pizza on broil. Broiling is a cooking method that uses direct heat on high heat. It is similar to grilling, but the heat source is located on the oven’s top shelf instead of below.
To broil a frozen pizza, preheat the broiler on maximum heat and place the frozen pizza on a baking sheet. After 5 minutes, flip the pizza, and then cook it for an additional 5 to 8 minutes until the crust is golden brown and the cheese is melted.
Be sure to keep a close eye on the pizza since the broiling time can vary based on the oven’s level of heat. Keep in mind that the cheese may brown quickly, so you may need to reduce the oven temperature if the pizza is getting too dark.
Once the pizza is done, remove it from the oven and enjoy!.
Can a pizza stone go under the broiler?
Yes, a pizza stone can go under the broiler. However, it is important to keep it a safe distance away, as the intense and direct heat can cause it to crack. Generally, a pizza stone should be placed on the top rack of the oven and away from direct flash.
The pizza stone should never come into contact with the heating elements of the broiler, as this could lead to extreme heat which could cause cracking or even breakage. Additionally, a pizza stone should never be used on the bottom rack of the oven when the broiler is used, as the stone could become scorched and smoking.
So, while a pizza stone can go under the broiler, it should be placed at a safe distance, and any contact with the heating elements should be avoided.
Should you oil a pizza stone?
Oiling a pizza stone is generally not necessary or recommended, as it could potentially cause the stone to smoke or become stained. This is especially true for certain types of oils commonly used for cooking.
Pizza stones are used to absorb moisture from the dough, so when oil is added to the stone, this can inhibit its ability to draw moisture out of the dough. To clean a pizza stone, simply scrape off any remaining pieces of food and soak it in a solution of warm water and baking soda—this will clean the stone while also killing any bacteria.
If you insist on oiling your pizza stone, use a baking oil that is free of flavoring agents (such as mineral oil) and make sure to rub it into the stone evenly.
What are the demerits of beehive oven?
Beehive ovens have several potential drawbacks. One of the most significant disadvantages is their cost. Beehive ovens may cost twice as much as conventional ovens, which can be prohibitively expensive for some households.
In addition, because of their unusual shape, beehive ovens are more difficult to clean. Some may find that the contoured interior walls make the cleaning process particularly tedious and time consuming.
Another disadvantage of beehive ovens is their relative complexity. They may be difficult for users to understand and operate for the first few times. There is a learning curve when it comes to controlling the temperature, and it can take users some time to get the hang of it.
Additionally, some people may find the shape of the oven to be inconvenient or awkward, making it difficult to use certain kitchen tools inside. Finally, beehive ovens need to be properly ventilated in order to function correctly, and this may be difficult in some kitchen spaces.
What is Otto Hoffman process?
The Otto Hoffman process is a method for manufacturing continuous-fiber-reinforced composite parts that was developed by the German company Otto Hoffman GmbH. This process starts with a continuous fiber-reinforced thermoplastic or thermoplastic composite prepreg tape or sheet, which is laid in a die to form the part geometry.
The tool is then heated and closed, applying pressure to the material, causing the tape or sheet to consolidate and adhere to the part’s geometry. Once the tool has reached the proper temperature, a vacuum is applied to densify the material and draw out entrapped air and volatiles.
Finally, the tool is cooled and opened to release the part.
The Otto Hoffman process is a method of producing high-quality, cost-effective parts that provides a number of critical advantages over traditional processes such as resin transfer molding (RTM), compression molding, and manual layup.
The process keeps fibers from crossing and wrinkle-free parts, ensuring near-net shape accuracy with minimal trimming and sanding. It also results in faster cycle times and improved repeatability and reproducibility of parts, greatly improving quality control.
The process also allows manufacturers to use simpler tools as well as less expensive materials, further cutting costs. Finally, since there is no direct contact between the tool and the part, there are no tool-wear issues, eliminating the need for frequent tool maintenance and repair.
What metal is coke?
Coke is a term that is often used to refer to a solid residue produced after the destructive distillation of coal. It is mainly composed of carbon, ash, and small amounts of other elements such as nitrogen, sulfur, and hydrogen.
Coke is a hard, brittle, greyish-black material that has a bulk density of about 776–1,100 kg/m3 and a heating value of about 24.8–29.6 MJ/kg. Its properties make it useful for many applications, in both the steel and aluminum industries.
It is also used for fuel in some industrial processes and to make carbon anodes for the production of aluminum.
Does coke burn hotter than coal?
No, coke does not burn hotter than coal. The two fuels have different burning characteristics, that result in slightly different temperatures. Generally, coal has a higher ignition temperature, which results in a hotter overall flame than burning coke.
This is because coal produces a more intense flame than coke due to its higher carbon content. Coke, on the other hand, is made of slightly lower carbon content, producing a lower flame temperature that’s less intense than burning coal.
However, coke does burn longer than coal and its higher volatile matter produces more heat energy that’s released over a longer period of time than with coal. Additionally, coke produces less smoke, soot, and pollutants than burning coal due to its low sulfur content.
Why are they called coke ovens?
Coke ovens are known by this name because their main purpose is to convert coal into coke, which is a combustible form of coal. Coal is heated inside large ovens in an oxygen-poor atmosphere and with temperatures ranging from 800-900℃, and the process of converting it into coke removes many of the impurities in the coal, resulting in a much purer and denser fuel.
The coke that is created can be used either as a combustible fuel and in the making of steel, as it burns hotter and with fewer byproducts than regular coal. The name ‘coke ovens’ came about due to their purpose in creating an end product of coke.
What is the purpose of a coke oven?
A coke oven is an oven which is specifically used for the processing of dense, carbon-rich source materials. The main purpose of using a coke oven is to produce a high-carbon fuel source known as coke, which is then used in many different manufacturing and industrial processes.
This fuel source can be used to fire blast furnaces and other similar pieces of equipment, as well as being utilized in the steel-making process. In fact, the majority of the world’s iron and steel production involves the use of coke ovens, because coke is a key element in the process of creating iron and steel.
When coal is heated in a coke oven, the volatiles, such as tars and hydrocarbons, are removed and the end product is a porous, dense, and very strong fuel source. Coke ovens also allow for the reduction of sulfur and nitrogen content in the finished product, making the resulting coke a much cleaner-burning fuel source.

Modern beekeepers may also have access to equipment and technologies that provide valuable data concerning the health and productivity of the colony. This helps beekeepers optimize the honey extraction process, helping to maximize the amount and quality of honey harvested.
Furthermore, modern hives are designed to protect colonies from mites and other pests. This helps reduce losses related to pests, which can have a more significant effect on traditional beekeeping methods.
Overall, modern hives provide beekeepers with the opportunity to manage their colonies in a more efficient and sustainable manner. This increased efficiency allows beekeepers to maximize their honey production while minimizing losses related to pests and climate change.
What is the most commonly used type of artificial hive?
The most commonly used type of artificial hive is the Langstroth hive, named after Rev. L. L. Langstroth, who invented it in 1852. The Langstroth hive is a rectangular box made of wood, with removable frames.
This style of hive is the most efficient way of managing honeybees due to its design and interior air spaces. The hive has an inner cover, a top box (also known as a “supers” or “brood box”), and adjustable frames, which provide the bees with honeycomb foundation.
The walls of the box are outfitted with removable frames, which hang from a top bar and can be removed for honey harvesting, checking for disease, or replacing frame combs. The frames also make it easier for the bees to access and store the honey.
Langstroth hives require minimal maintenance and can easily be expanded when necessary. The feature of removable combs also makes it the most efficient type of artificial hive. Therefore, it is the most commonly used today.
