Today, the need for high-quality clean electric steam also encompasses the requirements for zero emissions, high energy efficiency, and minimum spatial footprint configuration. The MightySteam® and OAB® steam generators produce non-condensing steam above the inversion temperature. Because there are no liquid droplets, the steam is of high quality. This improves steam performance for pharmaceutical use, clean comfort, and utility purposes.

With this modern energy and time-saving steam generator, there is no need for superheaters or boilers to 800°C+ for high-quality clean steam. No combustible fuel oils or gases,  No intense magnetic fields. No heating of flow pipes by induction. The temperature measured is that of the steam, not of the line.

Link to a Brief History of Steam Production Methods 

Why are MHI Electric Steam Generators so efficient? The HGA, GHGA, and OAB® steam generators have been a product of intense R&D and customer acceptance over the past decades. These modern steam generators use surface enhancement nanotechnologies, optimized high-impact heating materials, unique designs, and efficient control electronics. MHI Inc. holds several current patents in materials and heater designs. The graph below shows one example of MHI’s significantly improved materials in its build.

Deep Decarbonize and  High Efficiency with MHI Steam Generators:  The efficiency is close to 98%, rapid heat up within minutes for dry steam, touch screen safety features, zero CO2, and zero NOx. The generators offer variable steam flow and variable back pressure for constant temperature. The units are built to the highest level of user-preferred ASME codes. Modern ethernet protocols and electrical code compliance are offered. Contact MHI.

MHI Electric Steam Generators are clean:  Older steam boilers are fuel-fired (fossil-fired) and may use biofuels, coal, natural gas, and byproduct materials. The composition of exhaust gases from a boiler depends on the type of fuel used and may need cleaning treatment if they contain pollutants such as CO2, CO, SO2, Soot, Ash, NOx, and particles. MHI steam generators do not produce or emit these.   Traditional boilers require boiler rooms and a certified workforce,

MHI Steam Generators work hard for you. Depending on the model, they monitor the incoming electric phase variations, steam temperature, and steam flow rate, display any developing faults, and accept a host of user input controls. They even monitor the quality of water.

The  MightySteam® and OAB® Electric Steam Generators do not Produce any Greenhouse Gases like CO2, Methane, or NOx.   Only high-quality steam.

Steam generators are versatile. They are open flow systems where the steam rate and back pressure can be preset. The working of the steam generator does not require pressure as an independent variable. When a pressure rating for the steam generator is specified, the rating indicates the pressure tolerance of the system. There is a lot of flexibility for applications. A  pressure setting (value) can be input (user input) before the start of a cycle. This pressure setting may be the on-off trigger to turn off the generator for maximum process pressure. Or it can be an RH trigger from downstream.   The unit can be preset to automatically start again quickly and make high-temperature steam if the pressure or RH value falls.

What is saturated steam? When water molecules exist in a gaseous state, at a temperature above the boiling temperature of the water, it is called the superheated steam state. The boiling temperature depends on the pressure (e.g., 100°C for 1 atmosphere, 134°C for 3 atmospheres, and so on). Steam only at the boiling temperature is called saturated steam. 

What is the difference between saturated steam and superheated steam? Saturated steam is always steam at the boiling point, whereas superheated steam is at a higher temperature than the boiling point (at that pressure). The main difference between saturated and superheated steam is that the saturated steam is at a two-phase (liquid and gas) equilibrium temperature. So it could contain water droplets,  whereas the higher-temperature superheated steam is a high enthalpy gas (called high-quality steam as there are no water droplets in it). Superheated steam has a higher work potential compared to saturated steam. Work-potential enables mechanical work and chemical reactions. On the other hand, Saturated steam is often classified as low-quality steam.

What is high-temperature superheated steam? Steam above the boiling point at any pressure is broadly classified as high-temperature superheated steam*. Practically the temperature should be at least a few degrees centigrade above the boiling point to be classified as superheated steam. However, for many modern steam applications, the steam temperature has to be much higher than the boiling temperature (well into the superheated steam temperature range).

How is highly superheated steam made? Superheated steam is made with modern rapid steam generators like the OAB® and HGA. Current steam generators avoid high pressures, unlike the older traditional-boiler technology for a high steam temperature. The temperature for most combinatoric-steam applications should be higher than the inversion temperature (typically above 200°C) for reaping the benefits of superheated-steam-enhanced processes like drying, bio-energy production, high-level microbial and viral cleaning, energy production, antimicrobial, bio-digestion, chemical reactions, fuel production, syn-gas, methane reduction, and many others.   A new area of research is the combinatory steam area for energy reduction. * MHI definition is invoked. The temperature of good superheated steam is above any inversion temperature and much higher than the equilibrium saturation temperature. The equilibrium saturation temperature is the temperature (at a given pressure) where water or water droplets can coexist with steam-gas, i.e.,  the boiling point. Saturation temperatures depend on pressure, e.g., ~100°C at 1 Bar or 121°C at 2 Bar, etc. Instant high quality-clean steam with high temperatures ranging from 300°C to 1300°C is now readily available for steam applications. Such applications are multiplying. OAB®  and 4DSintering® are registered MHI Trademarks.

In contrast to conventional pressure-boilers, steam generators produce steam quickly on start-up, produce high-quality steam, and have fewer restrictions for piping. Where is high-temperature steam typically used? Fuel Production,  Antimicrobial Use, Comfort Humidity Addition, Oxidation and Erosion Studies, Food Industry, Packaging, Chemicals, Cleaning, Materials. Bio-processes, Energy, Hydrolysis, Process Heating, Flavors, Drying, Textiles, and even the Simulation of Martian Atmospheres (Nature, December 2017). Several more applications are listed here.

What is the inversion temperature of steam? The inversion temperature is most commonly known as the temperature at which the evaporation rates into pure superheated steam and completely dry air are equal. Typically ~200°C with some dependence on the surface.   The inversion temperature is the temperature for rapid antimicrobial action and rapid drying of ceramics.

Multipliers to process efficiencies. High-grade, high-quality superheated steam offers a good multiplier to process efficiencies – i.e. it is SmartSteam™. The temperature of the MHI steam models reflects the actual steam temperature. The savings efficiencies reported are from an On to Off condition (in contrast, please note that several boiler efficiencies are reported only at a steady-state). No requirement to heat any tubes or nozzles to produce steam. Several US and International Patents protect MHI steam generators.

Sustainability: Superheated steam enhances sustainability by reducing climate risk, accelerating energy transitions, increasing food security, and advancing better health outcomes.

What superheated steam is not? It is not mist nor fog. Mist and fog have some water droplets in the gas, and thus the name fog. View the comparison pictures of the difference between mist/fog-steam and a high-temperature steam-gas even when produced such that the nozzle area has no mist. In the picture, please note that MHI steam generators produce mist-free gas.

Why are these devices only possible from MHI? MHI uses patented nano-structured surfaces and other novel materials which have only recently become available commercially for use with active steam. MHI engineers have combined decades of thermal know-how and recent patented technologies with well-accepted/reliable MHI control systems for high power and high-temperature steam delivery. It is a part of MHI’s overall development strategy for intelligent power in modern thermal applications. Substantial energy savings result from OAB® steam use compared to combustion heating of boilers.
