Circulatic Steam Generator (Low NOx <9PPM NOx)

From 75BHP to 600BHP and up to 530 PSIG Design Pressure

The Circulatic® steam generator is is available in capacities up to 600 BHP and has a compact footprint saving you space. In less than 5 minutes the Circulatic can go from a cold start to full output and is available in design pressures required for your industry.

The Circulatic is also ideal for retrofit applications since our 500 BHP can fit in less space than a 300 BHP firetube boiler. A smaller footprint means savings on construction costs, not to mention
the quick response to load changes which provides flexibility for industrial and commercial applications.

The Circulatic ® is a forced recirculation watertube boiler that uses a drum as a steam separator and a reservoir of water to supply the coils. A recirculating pump draws the water from the drum and forces it through a set of parallel connected coils at the rate of 3 to 4 times the maximum steaming rate. The hot gases envelop the entire tube surface to achieve very high heat transfer rates.

The water is then pushed through a steam lance and a series of baffles in the drum where some of the water is flashed into steam and separated. The dry steam is released and the water is recirculated through the coils. The fuel and combustion air is controlled by a linkageless fuel air ratio control that responds to steam pressure. The feedwater is controlled by a water level control system and modulating feedwater valve.
