The Circulatic® Steam Generator 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.
