Coil Type Boilers

This is the conventional forced-circulation type water tube coil type boiler incorporating the unique principle of combustion known as ‘Reverse Flow. This increases the combustion efficiency and allows a high rate of heat release. It can be offered in both IBR and Non-IBR designs.


The boiler comprises of a jacketed MS shell housing a helical coil. The combustion air is forced through the jacketed shell by means of a centrifugal blower thereby getting pre-heated. The flame travels downwards inside the coil and the flue gases reverse upwards thereby giving two passes in the radiant zone ensuring complete combustion and higher heat flux. The third pass of the flue gases is in the convective zone between the coil and the inner shell. Flue gases then travel to the Economiser forming the fourth pass.
