With the continuous development of boiler manufacturing process and technology, fuel types of boiler have also increased, such as various combustible gases, fuel oil, biomass, coal and so on.
Once the flameout of gas-fired or oil-fired boiler is confirmed, the boiler should be shut down for inspection and maintenance in time according to the operating regulations. Only after the inspection and test are completed, the boiler can continue to be used.
Boiler produces heat via fuel combustion, so the burner is one of the important parts of boiler. And the air supply system is also an important component of burner. Whether the burner works well largely depends on its air supply system.
From the perspective of atomization mode, there are three kinds of burner used by boiler that are rotating cup atomization burner, pressure atomization burner and medium atomization burner.
In general, gas-fired boiler uses natural gas to heat water in order to provide heat source for underfloor heating and heating radiator, while condensing gas-fired uses condensation technology to recycle the thermal energy from the exhaust gas.
