ABSTRACT:
A low calorific gas is burned without the need of mixing or burning it with a high calorific gas. The method includes introducing either combustion air or low calorific gas into the mixing chamber, introducing the remainder into the mixing chamber through the perforated nozzles such that it is injected in the radial direction at a high speed from the holes to effect the mixing of the two in the mixing chamber, and injecting the mixed gas into the combustion chamber through the nozzles of the refractory baffle. The stable combustion of a low calorific gas alone by the aid of combustion air without the need of diffusing it into the atmosphere or burning it together with an expensive high calorific gas or oxygen-enriched combustion air is thereby effected, which greatly contributes to energy saving and environmental protection.
