Airtorch® Applications

Climate change is one of the most significant challenges of our time. Changing to efficient electric methods with the zero-emission green transition could spur huge economic gains as the world looks to curb climate change. The compact Airtorch® can eliminate fossil-fuel heating, rapidly aid deep decarbonization, and create flexible, Compact MW units available/ efficient chemical and fiber drying processes directly or as thermal storage batteries.

Industrial Products and Fuels for a Decarbonized Economy.

Industrial sectors such as manufacturing, energy, cement, drying, food, and chemicals actively seek sustainable alternatives to conventional heating equipment.

MHI offers low compact KW to high MW Airtorch® systems for the industrial sector that can aid in significant decarbonization with improved energy efficiency.

The Electric Airtorch® is a unique low-pressure-drop patented device used to heat air quickly and other process gasses to a temperature ranging from 20°C  to 1300°C. Use the Airtorch for electrifying high-temperature industrial processes in iron-making, alumina calcination, ore drying with controlled humidity, cement, bauxite roasting and other feedstocks, and lime production. Large Airtorch® uses from KW to MW are seen in Jet Engine Test Beds, Automotive Engine Test Beds, Chemical Synthesis, Clay calcination, Cement Industry, Drying, or Direct Reduction Processes. They find use in simulating heating in replacing combustion burners and preheaters, test rigs, running power plants, large die heat-up, chemical, and metallurgical processes, fuel production, and replacing fossil fuel calcination & kiln firing in several industries, including cement making,  system combustion/flow simulation, additions to cement clinker furnaces, curing, drying, or bonding of paper boards, removal of inorganic and organic salts, fuel cells, thermal energy storage, general heat treatment for bending and de-flashing/deburring, drum heating, plastic rolls, welding of plastics, soldering disinfection, drying, rapid paper, and pulp production, burner burn off, chemical reactions for environment and sustainability applications, and general uniform heating requirements. With devices like the Airtorch and similar high-value equipment, there is the potential to decarbonize roughly 80% of U.S. petroleum refining subsector CO2 emissions by 2050.

What is a decarbonized economy? A decarbonized modern economy has low greenhouse gas emissions from its industrial, transportation, and power generation sectors. The main impact of decarbonization can come from converting combustion methods to electrical methods. It is straightforward to convert combustion heating and drying to electrical heating and drying. An alternative way to decarbonize is to capture the CO2 and methane emissions and convert them into valuable products, even to CO (a toxic gas) with plasma catalysis. For 1 kWh of energy use or energy conversion by electric methods instead of burning carbon-containing fuels, about 0.8-2.2 lbs. of CO2 production can be prevented. A 100 KW device can prevent 80 – 220 lbs. of CO2 from being made every hour when electrical heating is employed instead of combustion or fossil fuel heating.

Case Study:   A 14.2 MW gas-combustion process air heater to a 12 MW MHI Electric Airtorch is a $3 million per year saving assuming 12 months, 30 days a month, and 24-hour day. (The additional social cost for the CO2 produced by burning natural gas has not been factored in this calculation).  Review energy calculations.

With over 5 billion metric tons of CO2 emissions in the United States in 2017, the utilization and conversion of CO2 into value-added chemicals, fuels, polymers, building materials, and other carbon-based products represent an economic opportunity. The MHI Airtorch and MHI steam generator products can be considered for such use.

Let us help with Industrial Decarbonization.


Decarbonizing the industrial sector is very important to address our climate crisis.   Almost a third of the greenhouse gas emission is from the industrial sector. CO2 emissions can be reduced quickly, as can emissions from the fuel-making, general industrial heating, and chemical and steam sectors. The first steps in decarbonization are eliminating heat production by fossil-fuel-fired combustion and relying on electrical energy instead for heating. This can significantly impact CO2 emissions; e.g., the cement industry produces about 10% of global human-made CO2 emissions, of which about 60% is from the chemical process and 40% is from burning fuel.

Although there may be a cost to changing to high-quality clean energy, the benefits are astounding. Greenhouse emissions from American, European, and other regions have already decreased by 23% – between 1990 and 2018, while the economy grew by 61% (click for reference). Not bad. But much more can be done using the Electric Airtorch or the MightySteam(R) steam systems.

Methane emissions are of great concern for global warming and climate change. Did you know that Methane has a global warming potential of almost 25 compared to carbon dioxide? Uses of the Airtorch include cold gas to be cracked (the cracking process), i.e., for Naphta or Ethane for ethylene production. If one is considering bio-fuels or valuable products like carbon monoxide (CO), formic acid (HCOOH), methane (CH4) and ethylene (C2H4), or ethane (C2H6) from CO2 conversion – please get in touch with MHI with your requirements.

What is Green Steel?   Steel that does not contain carbon. Iron ore is reduced at about 850C with hydrogen to make such steels. The carbonaceous (coke) reduction methods commonly used to produce iron are not employed when making green Steel. Consequently, there is no carbon present in such iron or Steel. Hydrogen-based direct reduction uses hydrogen instead of coal as a reagent to reduce iron ore to pig iron, eliminating the CO2 emissions from the equivalent process in a traditional blast furnace.

The microstructure of Steel is conditioned such that it competes with carbon steel with valuable properties of strength, flexibility, and toughness. Green steel production also avoids secondary carbon-reducing processes like the Basic Oxygen Process.   Green steels could include alloying elements like hydrogen, oxygen (see above for Fe/FeO composites), nitrogen or boron, aluminum, manganese, vanadium, molybdenum, etc. The chart below shows the power of critical carbon-containing steels and some without carbon.

Low-carbon energy inventions and innovations are essential to combat climate change, promote economic competitiveness, and achieve strong energy security.   MHI’s rapid heat and high-temperature gas and steam systems are tested for several uses, like eliminating combustion heating and enabling new chemical reactions. Closing the carbon cycle using excess CO2 is an appropriate intermediate step toward a carbon-free future. Use the powerful Airtorch® for continuous VOC removal, conversions, ore drying, rapid heat treatment, and surface treatments like finishing to hardfacing are the future. The C, CO, and CO2 gas reactions, including the Boudouard, Fischer-Tropsch, DMR, and variations, can be manipulated with hot process gases – including Air, N2, O2, CO2, Ar, and more. Examine other reactions below and do not hesitate to contact MHI for guidance:

2CH4  + H2O  +CO2 = 3CO  + 5H2 Well feasible above ~(760-860C) with easy methods for enabling all forms of downstream reduction. MHI reaction.

E.g., products that are reducing gases that can be used for various reducing reactions, including cleaning and shiny metal production, such as Fe2O3 + 3CO  = 2Fe + 3CO2  (weak) or Fe2O3 + 3H2 = 2Fe + 3H2O  above 520C. Note that CO2  + CH4 =2C + 2H2O   is always feasible at >100C but is extremely weak. Fe2O3 + 2CO  + H2  = 2Fe + 2CO2 + H2O  is always feasible but best above 1100C. The reaction  Fe2O3 + 3H2(g) = 3H2O(g) + 2Fe is feasible above 600°C but requires a higher temperature than that for proper kinetics. Fe3O4 + 4H2(g) = 4H2O(g) + 3Fe is feasible above 1100°C.  FeO + H2(g) = H2O(g) + Fe is a difficult reaction. Some green steel processing could use a mixture of Fe2O3 and nano-FeO, which, when reduced, can yield a metal-ceramic composite of Fe/FeO.

Or say:

CO2  + CH4  = 2CO + 2H2. Feasible above ~660C or via the steam reforming and water shift shown here. Unique combinations may be used for advantageous reaction engineering.

2H2  + CO2  = C + 2H2O  is feasible below 600C

H2  + CO2  = CO  + H2O is feasible above  900C

Is sustainable CO2 reuse via the Dry Methane Reforming (DMR) process cost-competitive?

Pyrolysis of Methane at high temperatures can produce hydrogen and other carbon-hydrogen compounds or various morphologies of carbon like C12, carbon -fibers, and other useful high-energy products and materials. Several reactions are possible that can be manipulated with pressure and catalysts:

CH4=2H2+ C (At 1000C K= 1 x 10^2, Delta(H)= positive)

2CH4= 3H2+C2H2 (At 1000C K= 1.2 x 10^-3, Delta(H)= positive)
