ABSTRACT:
A system to maintain the BTU output of a rotary drum, in which steam is supplied to the drum, and in which saturated steam and condensate is drained therefrom. An upstream flow meter and a downstream flow meter measure fluid flow, and in view of the small partial pressure of the condensate and of the large volumetric difference between the condensate and the steam which was condensed, the difference between the flow meter readings can be understood as a measure of BTU's provided as a consequence of the condensation which occurs in the drum.
