4-1 Recovery Boiler Equipment and Operation. 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.Get Price
A gas boiler functions in a similar way to oil or biomass boilers, with the central element being the burner; this is switched on and off by a heating control.You can either trigger the switch manually or by setting the thermostat to react when the temperature drops below a certain level.. A Piezo ignition, ignites for a period of one to two seconds and then after around one second the gas Get Price
An oil boiler should reach the same efficiency as a gas boiler. According to building regulations, oil boilers must have an energy rating of at least 86 per cent, or A+. A condensing oil fired boiler will usually have an efficiency of 90 per cent or higher. Oil is a more efficient fuel than gas.Get Price
