Typical model numbers shown below. If a pressure rating is not required please inquire about MHGA models.
MHI provides UL/ CE rated controllers.
Pressure vessel third party rating is offered (e.g. Section V111. Div. 1).
The minimum temperature is 200°C. Pressure and flow rate are independent settings. ASME PV ratings are provided when requested. The control panel can be CE or UL or with cUL ratings. Flow rate can be varied from about 30% to full amount of the specific model.
Modern HMI panels for touch screen interface for operator ease.
On Demand Steam: GHGA™ and MHGA™, choice of models.
GHGA™ when the back pressure expected is more than 2Barg. MHGA™ when it is less. Please specify in the RFQ.
From 3Kg/hr to 200 Kg/hr Scalable Super-heated Steam Platform.
Control the flow and temperature independently with flow and power controllers. Independent pressure control.
Visit this page particularly if:
You are looking for high efficiency on-demand high temperature steam generators
You are looking for independent control over temperature, flow rate and pressure
You are considering changing from a large combustion boiler to a clean steam generator including discrete generators for every station
If you are planning new fuel and CO2 conversion or related technologies
if you have to optimize steam chemical reactions for syngas.
When dedicated to sustainability and efficiency with steam generators.
If you prefer to decouple pressure and temperature in your steam output.
When very high temperature say 400°C, 800°C, 1300°C steam is critical for use.
GHGA – Scalable Platform Models/Features. Set the flow, temperature and pressure independently. Set flow on a touch screen HMI.
For fine tuning pilot process development for quick scale up to production.

Typical and frequently asked questions:
Q: I need a variable steam rate generator at a maximum temperature of 400°C to 800°C. Can I use your steam generator GHGA models ? Ans: Yes, the GHGA models are the correct choice for variable flow and variable temperature requests. The price will also depend on the pressure vessel rating and range of variable (adjustable) steam flow. Typically we are asked for 3-6 Kg variable or 4-12 Kg variable steam at the high temperature with unit-adjustable back pressure.
Q: Can you provide a shell of 40 Bar. Ans: Yes we can provide ASME Section V111, Div 1 standards with external rating.
Q: Can I get a touch screen HMI control panel. A: Yes of course, this is our standard.
Q: I have a 49 KW boiler, can I use your steam generator instead? Ans: Yes: The closest fit is the GHGA-36-(PV). This is a 48 KW unit. It can be on off at will. No idling required. The temperature out-put of the steam will be between 300C and 800C depending on the flow settings and power settings. The unit will produce 36 Kg/hr steam at the maximum temperature. The price will depend on the pressure required. The lowest priced systems are when the steam flow rate is fixed.
Q: Do steam generators work differently than boilers? Ans. Yes steam generators work in a different manner compared to pressure boilers (1) they are instant on-off, no idling required (2) in a clever way the pressure will only build to the maximum line requirement in order to improve the efficiency (3) temperatures can be set for very high temperature dry steam, and (4) they can be easily matched to other line or cross line pressure flows. Saves energy. Allows for new reactions to be explored.
Q: I have a 200 Bar steam line that feeds the entire industrial testing plant, can I use discrete 40 Bar steam GHGA units from you? Ans: Yes the savings are enormous and chances are you will also convert from a coal, oil or gas fired boiler to a clean unit. On-off at will. No dangerously long piping at high pressure and no idling.
Highly Scalable OAB® or GHGA units can produce from 4 kg/hr to over 1000 kg/hr. The 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 high quality electronic power and temperature control panels.
