BOILER WATER TREATMENT INTRODUCTION A boiler is a closed vessel in which water under pressure is transformed into steam by the application of heat. In the boiler furnace, the chemical energy in the fuel is converted into heat, and it is the function of the boiler to transfer this heat to the contained water in the most efficient manner.


steam can occur. To prevent boiler tube chocking and overheating of the boiler tubes the blow down is necessary. The blow down is the water removed from boiler to maintain the solids level in the boiler drum. This can be calculated as follows: E = Evaporation or steam generation rate. S = Amount of solids (ppm) B = Blow down (m3 / hr)
