The first one is steam curing at ordinary pressure, while the other is done at a high pressure. In ordinary pressure steam curing, a tarpaulin or PVC sheet is used to form the enclosed area around the concrete component that needs to be cured.Cement Plant an overview ScienceDirect Topics,Thermal power station/waste heat recovery. When a cement plant installs a thermal power station (TPS) to supplement or to ensure availability of power on a continuous basis, it requires large quantities of water for generation of steam. The steam is condensed in condensers and returned to the circuit.
