  • What is a Steam Boiler? Working, Types of Heat Transfers

    Jul 19, 2019 · Generally, Power plants require steam for the purpose of heating. Hence, this purpose is fulfilled by the boiler, where the steam is produced by boiling water. Basically, the steam is produced by boiling water beyond its boiling point where it changes its state from liquid to vapor and this vapor is known as steam.Get Price
