Operating Concept

The Circulatic® steam generator is a forced re-circulation 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 re-circulating 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withdrawn from the drum and the water forms a reservoir of heat saturated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 blowout when the blow-down valve is opened.
