a strategy for loss reduction. A coal fired boiler is an enclosed vessel that provides a means for combustion heat of coal to be transferred into water until it becomes steam. When water is boiled into steam its volume increases about sixteen hundred times, producing a grander force like explosive that will run the turbine in later processes to generate electricity.

How to Destroy a Boiler -- Part 1

The boiler is actually an oversized distillery in that the water that enters the boiler is vaporized to steam, leaving the solids behind. Depending on the amount of solids in the water, or hardness, the residue is sometimes visible when a pot containing water is boiled until all water is vaporized.

Evaporative Gas Turbine (EvGT)/Humid Air Turbine

Treated boiler feedwater is first deaerated to avoid use of expensive metallurgy in the downstream piping and heat exchange coils and then fed to the economizer of the HRSG located in the gas turbine exhaust. The heated boiler feedwater is then fed to the evaporator via the steam drum connected to the evaporator coils located within the HRSG.
