ABSTRACT:
A method is proposed for recovering high-temperature exhaust gases of high inflammability in terms of carbonaceous concentration from the partial combustion, at atmospheric pressure or near atmospheric pressure, of a mixture of pulverized bituminous or subbituminous coal and air as oxidizer gas, enriched with oxygen gas in a combustor apparatus having a cylindrical combustion chamber with a tangential injection duct, through which the fuel mixture is introduced into the combustion chamber to develop into a rapidly swirling vortex optimizing burning over a short period of time. As a result, the high-temperature, inflammable exhaust gases are generated, of which the heat is recovered to produce steam in a boiler. After losing portion of their heat to the boiler, the inflammable gases, following purification by a filter and desulfurization unit, recovery for subsequent thermal use in boilers, metallurgical or other chemical processes. The ash and other non-combustible products present in the gases are caused to move out outwardly in the combustion chamber as molten slag, forming the outermost part of the vortex, and flow down along the inner wall of the combustor apparatus into its bottom where the slag is collected through a tapping port at the bottom.
