Packaged Steam Generators

The CIRCULATIC steam generator is a forced recirculation water tube boiler in which water under pressure circulates at high velocity through a set of nested, parallel connected, coils while forced draft combustion gases travel across the coils. The hot gases envelope the entire tube surface making maximum use of both radiant and convective heat to achieve very high heat transfer rates.

Water at saturation temperature is drawn from the steam drum and forced through the coils at three times the maximum steaming rate by the recirculating pump.

The water is then carried back to a steam lance, in the top of the same drum, where steam is released and effectively separated. The 99%+ dry steam is withdrawn from the drum and the water forms a reservoir of heat saturated water to feed the recirculating centrifugal pump. Solids collect at the bottom of the drum and are blow out when the blow-down valve is opened.

A pressure sensitive control which responds to the steam pressure in the drum, regulates the supply of fuel and air to the burner and provides efficient combustion over the complete modulating range of the boiler. High efficiency is obtained, without thermal shock, over the full operating range, not only at rated output.

The built-in safeguards which monitor the main flame and initiate shutdown in the event of loss of flame, as well as the location of the steam drum out of the firing area, assures maximum operational safety of the boiler.
