Excerpt from this story from Inside Climate News:

Inside a cinder block office building perhaps best known for the Hindu temple and table tennis club next door, a startup company is testing what may be one of the hottest new developments in clean energy technology.

At the back of a small warehouse laboratory buzzing with fans and motors, an MIT spinoff company called Electrified Thermal Solutions is operating something its founders call the Joule Hive, a thermal battery the size of an elevator.  

The Hive is a large, insulated metal box loaded with dozens of white-hot ceramic bricks that convert electricity to heat at temperatures up to 1800 degrees Celsius—well beyond the melting point of steel—and with enough thermal mass to hold the heat for days.

As the price of renewable energy continues to plummet, one of the biggest challenges for the clean energy transition is finding a way to convert electricity to high temperature heat so societies don’t have to continue burning coal or natural gas to power heavy industries. Another thorny issue is finding a way to store energy—in this case heat—for when the sun doesn’t shine and the wind doesn’t blow.

“If you are running an industrial plant where you’re making cement or steel or glass or ceramics or chemicals or even food or beverage products, you burn a lot of fossil fuels,” Daniel Stack, chief executive of Electrified Thermal Solutions, said. “Our mission is to decarbonize industry with electrified heat.”

The industrial sector accounts for nearly one-fourth of all direct greenhouse gas emissions in the U.S., which drive climate change, according to the EPA. Thermal batteries powered by renewable energy could reduce roughly half of industry’s emissions, according to a 2023 report by the Center for Climate and Energy Solutions, a nonprofit, and its affiliated Renewable Thermal Collaborative. 

Additional emissions come from chemical reactions, such as carbon dioxide that is formed as an unwanted byproduct during cement production, and from methane that leaks or is intentionally vented from natural gas pipes and other equipment. 

The challenge to replacing fossil fuel combustion as the go to source for heat, is that there aren’t a lot of good options available to produce high temperature heat from electricity, Stack said. Electric heaters, like the wires that turn red hot in a toaster, work well at low temperatures but quickly burn out at higher temperatures. Other, less common materials like molybdenum and silicon carbide heaters can withstand higher temperatures, but are prohibitively expensive.

As a grad student at MIT, Stack wondered if firebricks, the bricks commonly used in residential fireplaces and industrial kilns, could be a less expensive, more durable solution. Bricks do not typically conduct electricity, but by slightly altering the recipe of the metal oxides used to make them, he and ETS co-founder Joey Kabel were able to create bricks that could essentially take the place of wires to conduct electricity and generate heat.

“There’s no exotic metals in here, there’s nothing that’ll burn out,” Stack said standing next to shelves lined with small samples, or “coupons,” of brick that he and his team have tested to find the ones with the best heating properties.

Hey fun fact I just learned today:

Did you know that milk - especially curdled milk - was used as a strengthening agent and for waterproofing floors from Roman times up to the late middle ages?

Casein, the protein in milk, is super strong and flexible when dry. It's one of the main things that made Roman concrete so tough!

It also mixes with quicklime to form a super hard, waterproof surface akin to modern day sealed concrete - without the expense!

This Quicklime x curdled milk solution was mixed with wood ash, sand and clay to form Lime putty, which was popular between 1290-1850 as subflooring across europe, though especially the coasts and England, where limestone is abundant, because it was extremely durable, cheap to make, waterproof, and remains one of the most insulating (and fireproof!) materials ever made.

Modern firebricks are made in a similar way, but without the casein.

The inner walls of some houses in England are lined with this stuff too, but it was not common as a wall putty because it takes a while to dry and would slide off. However, slaked lime was often still used to "paint" the inside and outside of houses to preserve heat, add brightness (remember there's no electric lights at this time) and deter pests. The caustic nature of quicklime deterred mice and rats from chewing on it, because it upset their stomach (and often killed them). Bugs, mold, and bacteria don't like it either! That's why you can still find lime washed houses today, especially in rural parts of North and Western Europe.

Depending on the specific metallurgical process being carried out, the furnace may be operated under various atmospheres, including inert gases such as nitrogen or argon, reducing atmospheres like hydrogen or carbon monoxide, or oxidizing atmospheres such as air.

Temperature regulation is critical in pit furnace operation, as precise heat treatment parameters are essential for achieving the desired metallurgical properties in the finished product. Advanced temperature control systems, often integrated with computerized automation, allow for accurate monitoring and adjustment of temperature profiles throughout the heating and cooling cycles.

Applications and Industries

Pit furnaces find widespread use across diverse industries where heat treatment and thermal processing of metals are required. In the aerospace sector, for instance, pit furnaces play a crucial role in the manufacturing of aircraft components such as turbine blades, landing gear, and structural elements. These furnaces are employed for processes like annealing, stress relieving, and solution heat treatment, which are essential for enhancing the mechanical properties and durability of aerospace materials.

Similarly, in the automotive industry, pit furnaces are utilized for heat treatment processes such as carburizing, quenching, and tempering, which impart strength, hardness, and wear resistance to critical automotive components like gears, shafts, and bearings. The ability to precisely control the metallurgical properties of these components is paramount for ensuring the safety and reliability of vehicles on the road.

In addition to aerospace and automotive applications, pit furnaces also serve various other sectors, including tool and die manufacturing, oil and gas exploration, and industrial machinery production. Their versatility, coupled with advancements in furnace technology and process control, continues to expand their utility in new and emerging fields.

Conclusion

Pit furnaces stand as enduring testaments to humanity's mastery of metallurgical science and engineering. From humble beginnings as primitive earth pits to sophisticated modern chambers of heat and transformation, these furnaces have evolved alongside civilization, adapting to meet the ever-changing demands of industry and innovation. As we continue to push the boundaries of material science and engineering, pit furnaces will undoubtedly remain indispensable tools in the relentless pursuit of stronger, lighter, and more resilient metals.

Forge Build Part III: Finishing the Forge

Painting the Forge

Using high temp primer and paint (rated at 1500°F) I painted the forge. I followed the instructions on the cans (2 coats each if I recall correctly). After the paint was on and dried, the instructions say to cure the paint in an oven. Since my wife didn’t want this beauty in her new oven, I got out the heat gun and slowly moved it around the forge. This paint has held up really well over time. The key is having the patience, which is hard for me at times.

Insulating the Forge

I lined the forge with a special ceramic fiber forge insulation, two 1″ thick layers. It isn’t cheap but very necessary (link to it on Amazon at the bottom). Once in the forge, I lightly sprayed water to the inside surface and I then thinned some ITC-100 refractory cement with water. The wetting of the insulation helps the cement adhere to the insulation. It is also best to dab it on with a brush and not use strokes. Keep the refractory cement stored properly as it will be used again. Once in a while, you will need to touch up as it is brittle and its good to have around for that.

Be sure to follow ALL of the safety instructions with the insulation, which includes wearing gloves and a respirator.

You can put the firebricks on the bottom before or after the cement coating. I put them in prior and it worked fine. These come in a box of 6 and I used two. If you ever use borax flux (for forge welding) it will wear on the bricks over time. Having extra around never hurt.

Firing the Forge

With the forge done, I went outside and fired it up. I was a bit nervous and excited before the initial firing, but I kept safety at the forefront of my thoughts. I put the tank as far back as possible, and I lit it by putting in a small piece of scrap wood that I lit with a torch and then slowly let the gas in.

Now I am more comfortable and light it directly with the MAPP torch. Before lighting, I set the system pressure to about 10 PSI before opening the valves to the burners. Once pressurized, I drop the chokes on the burners and expose the intakes, insert the end of the MAPP torch (it has a curved burner so my hands with gloves on are off to the side) and open the main gas valve then the burner valves.

When I shut it down, I make sure to close the chokes, disconnect the gas, and let the forge sit and cool. I make sure to not start it up if I don’t have the time to hang around while it cools, which isn’t fast.

I know this isn’t very detailed, but a long read (it took even longer to make) but I hope you enjoyed it. If you want to build your own, be safe, I am not responsible for your actions. This is how I went about making mine.
