1.Boiler is equipped with imported brand burner, according to different fuels selected different burners, wide adaptability.
2.Gas-type selection Baltur GI 1000 LXME MB burner, their main pipe fittings such as quick-break valve, filter, pressure regulator, leak detection device is also a full set of imports, stable and reliable performance.
3.Light oil selection GI 1000 DSPG MB. The gas is filtered and pressurized, and then burned into the corrugated furnace by the burner for combustion. The fuel is atomized by the burner and fed into the corrugated bile for combustion. The formation of high temperature flue gas in the furnace and the back to the combustion chamber for radiation heat transfer, and then washed the second and third turn after the convection tube into the smoke box, and then through the energy-saving device, and finally by the chimney into the atmosphere.
