Fully Automatic Boiler

The main boiler comprises of a double-jacketed M.S. Shell housing a helical coil placed within it. The combustion air is forced through the jacketed shell by means of a centrifugal blower thereby getting preheated and keeping the outer shell cool. The pressure jet burner atomizes the fuel and combustion is established. The flue gas flows axially downwards and on reaching the bottom, it reverses the upwards thereby completing two passes in the Radiant zone. These two passes in Radiant zone ensure complete combustion and high rate of heat flux.
