Characteristics of boiler feedwater. Water has higher heat capacity than most other substances. This quality makes it an ideal raw material for boiler operations. Boilers are part of a closed system as compared to open systems in a gas turbine.The closed system that is used is the Rankine cycle.This means that the water is recirculated throughout the system and is never in contact with the

When it comes to the steam boiler vs hot water boiler, the operating principles are more or less the same. Both steam boilers and hot water boilers (also called hydronic boilers) involve the heating of water and creation of steam through the burning of fuel. The heated water is transmitted through boiler tubes, while the steam created is circulated throughout the facility with the assistance
