A self-acting, normally closed tem perature control with sensor in the vent line can control the coolant flow. This minimizes water usage, and where condensed flash steam is returned, avoids overcooling of the water in the receiver.

tank vent. If boiler feed quality water is used, the warmed water and con densed flash steam is added to the condensate in the receiver and reused. Condensing water which is not of feed water quality is kept sep arate from the condensate in the receiver as shown dotted.

Residual flash steam for which no use can found often causes a nui sance if vented to atmosphere, and of course carries its valuable heat content with it. This steam may be condensed by spraying in cold water, in a light gauge but corrosion resis tant chamber fitted to the receiver
