Profile: Vijay Engineering is mainly deals with boilers. Our coil type non-IBR boilers incorporate unique revolutionary principle of combustion known as reverse flow, which increases combustion efficiency and allows a high rate of heat flux. 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 which ensure complete combustion and high rate of heat flux.
