Combination Boilers. These are the simplest systems, as the only controls are those for central heating. Principle of operation. A combination boiler, or combi, is a boiler which heats hot water on demand, and additionally can function as a normal boiler to heat hot water for radiators.
prevent low efficiency boilers being fitted. Types of boiler • Conventional boiler - This boiler is the most basic type, it just burns fuel to make heat for central heating or hot water. • System boiler - This boiler provides central heating only or heating and a store of hot water in a hot water cylinder (tank).

Boilers 291 Coagulationa method for concentrating and removing suspended solids in boiler feedwater by adding chemicals to the water, which causes the impurities to cling together, p. 301. Condensatecondensed steam, which often is recycled back to the boiler, p. 294. Dampera movable plate that regulates the flow of air or flue gases in boilers,
boilers allowed to swing with the load (variable firing rate). Figure 3 shows a boiler master control diagram to provide these adjustments. Each boiler master has a bias adjustment and an auto/manual transfer switch. In manual, the operator can reduce the firing rate to a low fire condition for shutdown, or hold the firing rate
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 heat that it generates is transferred to the water through the heat exchanger.

brand boilers can do more, with less field wiring, and fewer aftermarket controls and components improving the operation of both new and replacement boiler installations. These application drawings include detailed wiring diagrams, and set-up details, allowing installers to fully utilize the capability and
