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

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 that 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 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.  Saturated steam is often classified as a low quality steam.

What is high-temperature superheated steam?  Steam at 250°C above the boiling point is broadly classified as high-temperature superheated steam*. For many modern applications of steam, the steam temperature has to be much higher than the boiling temperature (well into the super-heated steam temperature range).

How is it made? With modern rapid steam-generators like the OAB® and HGA.  Modern steam generators avoid the requirement of requiring high pressures unlike the older technology traditional-boilers.  The temperature for most combinatoric-steam applications should be higher than the inversion temperature (typically above 260°C) for reaping the benefits of a superheated-steam enabled processes like drying, bio-energy, high level cleaning, energy production, antimicrobial, bio-digestion, chemical reactions and many others.   A new area of research is the combinatory steam area for energy reduction. * MHI definition is invoked.  The temperature of good super-heated 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 egg the boiling point 100°C at 1 Bar or 121°C at 2 bar and so on.  OAB®  and 4DSintering® are a registered MHI Trademarks.  Instantly made high quality-clean steam with high temperatures ranging from 300°C to 1300°C is now available from a variety of models for many beneficially steam applications.  Such applications are growing  rapidly.

Where is high temperature steam typically used? Antimicrobial Use, Oxidation and Erosion Studies, Food Industry, Packaging, Chemicals, Cleaning,Materials. Bio-processes, Energy, Hydrolysis, Process Heating, Flavors, Drying,Textiles and even for the Simulation of Martian Atmospheres (Nature, December 2017).  Several more applications are discussed at the bottom of this page.  MHI Steam generators are influencing the ease of use, and ease of installation of steam devices because of the availability of the higher temperatures from them.   In contrast to conventional pressure-boilers, steam generators produce steam quickly on start-up, produce high-quality steam and have less restrictions for piping.

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.

How is good high temperature steam superheated steam made? Such steam is often produced efficiently by special patent protected steam generators without the need for any pressure requirement during the generation process. When the steam is at a high temperature, especially above the inversion temperature, key-applications like continuous rapid drying, rapid heat transfer, reforming type reactions, cleaning at many levels, or bio-energy and other rapid reactions become feasible. Steam generators are very rapid acting (produce steam within seconds). Superheated steam often leads to a reduction in the number of boilers, a reduction in the feed water usage, reduction in boiler load, improvement in the process timing, a reduction in the reagents, and emulsification with a overall better yield. Inquire about 3DPrinting and 4DSintering with steam.

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 with the well accepted/reliable MHI control systems for high power and high-temperature delivery of steam.  It is a part of MHI’s overall development scheme of smart power for modern thermal applications. Substantial energy savings result from OAB® steam use in several applications.

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 reflect the actual steam temperature. The savings efficiencies reported are from a On to Off condition (in contrast please note that several boiler efficiencies are reported only at steady state). No requirement to heat any tubes or nozzles to produce steam.  Several US and International Patents protect MHI steam generators.
