Steam's capacity to transfer heat is also used in the home: for cooking vegetables, steam cleaning of fabric, carpets and flooring, and for heating buildings. In each case, water is heated in a boiler, and the steam carries the energy to a target object.
boiler of this type, filled with water and ready for function, can weigh as much as 165 tons, which corresponds to the weight of 120 VW Golfs. Hot water or steam boilers are relatively similar in design (Figure). The boiler pressure vessel is a horizontal, cylindrical tube closed at both sides with an end plate and insulated all around.
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.
A steam boiler is a vessel that contains water and a heat source powered by oil, coal or gas. The boiler transfers heat from the heat source to the water vessel, thereby turning the water into steam. This steam exits the vessel through a pipe and is transported to another location where it can be used for cleaning,
