BOILER WATER TREATMENT. A boiler is a closed vessel where water under pressure is transformed into steam by the application of heat. This process is useful for a variety of industries, from industrial and manufacturing environments to food and beverage processing. In the boiler furnace, the chemical energy in the fuel is converted into heat.
