Why use the OAB®
Real Cost of Project: If you use a gas fired boiler say 72 KW units perhaps could be used but one has to add several hours of boiler running time. One will in reality use a lot more energy, because unlike the OAB® steam generators, gas boilers are not a quick start and shut down operation. Please add additional monitoring and labor time. Also add inspection time and pressure fittings/lines will be required with any conventional boiler. For gas boiler one needs a separate set up and construction management crew and installation crew. Boilers can be dangerous - there are many instances where boilers an autoclaves may have exploded (blown-up) e.g. recent report.
Clean: For each kWh of electricity generated by fossil fuel fired power stations about 0.45kg of carbon dioxide is produced. Burning fuel will produce CO2 in a gas or fuel fired boiler. For the electric boiler there may have been CO2 produced at the power plant. Big plants have more efficient cleaning possibilities. Please vent carefully if burning fuel.
Traditional boilers yield saturated steam (Tsat and Psat are linked). Boiler efficiencies increase with lower pressures. At 10 Bar the saturation temperature (Tsat~180C) is much lower than the basic OAB output temperature. High temperature can almost instantly be achieved with the OAB and other MHI steam generators at a safer 1 bar pressure. Regardless please take all precautions e.g. that include high quality safety glasses, non-porous insulated clothing, high temperature non-porous gloves, proper boots and all other safety equipment when in the presence of steam generators.
If the steam is for heating purposes, please compare the enthalpy. If the steam is for work purposes please use the work potential row below, the work potential increases with both temperature and pressure. Work potential is measured from 25°C base temperature. The cost of boilers increases for very high pressure ratings. However even at 100 Bars the saturation temperature is only 311°C. Again a fairly easy and routine temperature from the OAB steam generator.
1 Bar =100000 Pa = 14.5 psi
10 Bar =1000000 Pa =145 psi
100 Bar = 107 Pa = 1450.3 psi

Superheated Steam Generators Applications
The kg/hr is nominal steam production rate. Temperature and production rate are setting dependent.
350 Models expected to produce steam temperature in the range of 300-380°C
550 Models expected to produce steam temperature in the range of 500-700°C
750 Models expected to produce steam temperature in the range of 700-900°C
The output for the clean steam is easy to fit. Sealant is provided for the user when attaching tubing for steam travel beyond the exit. Vittori tubes which are insulated flexible tubing with connectors are also available from MHI. Please Contact to request additional information.

MHI's One Atmosphere Boiler superheated steam boiler features patented InstaSteamâ„¢ technology, allowing for rapid startup times, unparalleled efficiencies and up to 1300°C temperatures. BoilerFreeâ„¢ technology allows most OAB units to be installed without the need for traditional boiler certifications. The OAB® is ideal for use as an industrial steam generator, for dewrinkling operations, heating of vats, cpg bottle labels, cleaning at several levels, superheated steam drying and dozens of other specific applications requiring a high efficiency boiler that does not require standard boiler certifications. Use to replace boilers with better efficiency or to augment steam applications.
Pure Steam. Clean Steam. One Atmosphere Boilers generate superheated steam that is free of contaminants. The OAB's steam is ideal for pharmaceutical, cosmetics and other industries requiring the highest quality steam. OAB steam is also suitable for use as utility steam in many applications due to its high energy content. Steam is a very powerful non-toxic agent but adequate safet care must be taken when using hot steam. Periodic treatment with high temperature steam is recommended (when used properly) to achieve maximum benefits. Steam quality can sometimes be checked with the proper steam chemical indicators. For bacterial testing please check with a professional microbiologist.
Highly Scalable. OAB units can produce from 1kg/hr to over 1000kg/hr. Modular design allows for easy upgrades and utilizing the unit where it is needed, all without routing steam or venting pipes. MHI is well known for Smaret heating devices.
Compare Efficiency. Three types of efficiencies are important to consider. (1)the efficiency of the steam generation device where the OAB® and MightySteam® excel; (2)the efficiency of the downstream process that the steam is used for; and (3) the overall water usage efficiency and propensity to recycle the water. The one atmosphere steam-gas generator/boiler performs well in all three categories.
How does one increase the rate of production?
- Short Answer: Increase the temperature of t he process gas or steam.
- Long Answer: Please click to Steam Calculator page.
Better conversion factors allow OAB units to use less resources to produce more steam. A standard OAB steam output at 350°C, is almost at the theoretical efficiency of power conversion for the OAB steam generation! The OAB's rapid start-up (generally with a minute from cold start) also adds considerably to the overall lowering of energy usage.
Getting to temperature quickly and faster results in lower operational wear and related costs i.e. an overall higher productivity with corresponding higher kinetics. The output velocity of the 550°C OAB steam is very high - almost 40m/s or more. This feature is used for the uniform heating of kettles/heat exchangers and for reaching large piping distances without significant loss of temperature. For industrial vats and kettles, the heating rate makes a considerable difference to the overall process economics. A general rule of thumb of productivity from traditional pressure boilers is - (0.35 Gallons of heated product like water)/kWhr (energy). For the OAB it is closer to - (1 Gallon/kWhr) i.e. almost three times (numbers may be lower or higher as they are situational dependent and one needs to evaluate on a case by case basis).
