Read MoreA New York Tech Explains. September 26, 2017. How a boiler works really depends on the kind of boiler you have. But the primary purpose of all boilers is to transfer heat to water. Basically, boilers work by heating water or producing steam that is then used to heat a home. But, of course, that's a barebones explanation of how boilers work.
Read MoreA 1930s boiler, coal fired. Photo courtesy of Customer Services, Ideal Heating. The living area of a 'modern' 1930s and 1940s house was the kitchen, and it contained a coal-fired 'boiler' which heated water. The hot water was sent through a pipe into the hot-water tank in the airing cupboard which supplied the hot taps in the kitchen and bathroom.
Read MoreThe boiler is a closed vessel, where the water is stored. Hot gases are formed by burning fuel in the furnace. These gases are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boiler's basic principle is to convert water into steam with heat energy.

Read More2019/12/30 · Pressure Change Range. Pressure will change when the unit fires up the heat. In most cases, it should rise to about 20 psi while its heating element operates. That's optimal at normal temperatures. Pressure changes of a few psi one way or the other can be brought about by atmospheric conditions. Most boilers are safe up to around 30 psi, at
Read MoreFuel flow control. The primary boiler fuels are coal, oil, and gas. Oil and gas involve the simplest controls, since they can be measured easily and flow is regulated by a control valve in the fuel line. On the other hand, since coal is an unmeasured fuel, the control system is open-loop, in which a fuel demand signal positions a coal-feeding
