Explain the principle of the double evaporation boiler

The double evaporation boiler is proof against this by virtue of the fact that the boiler proper operates on a closed circuit, its initial charge of high quality water being continuously evaporated in the boiler and condensed in a heat exchanger producing low pressure steam,and requiring occasional make-up to replace incidental losses.

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.

Boiler Efficiency and Steam Quality: The Challenge of

Boiler efficiency measures how much combustion energy is converted into steam energy, while steam quality measures how much liquid water is present in the steam produced. A major benefit of using steam as a heat transfer medium is the large amount of heat released when it condenses into water.
