Understanding Steam & Boiler Heating Systems …

2016-1-13 · Boiler Systems Operation. In steam heating systems, a boiler furnace heats water by means of a gas or oil-fired burner and turns it into steam. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again.

Characteristics of boiler feedwater - Lenntech

Since water impurities cause boiler problems, careful consideration must be given to the quality of the water used for generating steam. The composition of boiler feed water must be such that the impurities in it can be concentrated a reasonable number of times inside the boiler, without exceeding the tolerance limits of the particular boiler
