What is the Difference Between Subcritical and
Supercritical boiler works at temperatures around 538–565°C and pressures above 3,200 psi. A supercritical boiler has a system with variable evaporation endpoint. These boilers are drum-less. Hence, the evaporation takes place at a single pass through the evaporator. The flow of fluid, most of the times; water, is induced by the feed pump.Get Price
