Chapter 14 Boilers - Pearson

Working Principle. Both gas and oil fired boilers use controlled combustion of the fuel to heat water. The key boiler components involved in this process are the burner, combustion chamber, heat exchanger, and controls. The burner mixes the fuel and oxygen together and, with the assistance of an ignition device, provides a platform for combustion. This combustion takes place in the combustion chamber, and the …

2. BOILERS - Bureau of Energy Efficiency

Apr 11, 2015 · Feedwater Control For Boilers Feedwater control is the regulation of water to the boiler drum. Risks : If the level is too high, may interfere with the internal operation of internal devices in the boiler drum, such as - flooding of steam purification equipment can occur. If the level is too low, reduction in efficiency of the treatment and recirculation function, undesired pressure build up, over heating of …

Central Heating boiler controls explained

Boiler, central heating and hot water cylinder controls. The controls fitted to a domestic boiler and wet central heating system should allow you to control when your home (and hot water if appropriate) is heated and the temperature it is heated to. Using the controls effectively will improve the energy efficiency and minimise running costs without affecting comfort.
