This invention teaches the use of a cyclone gassifier fueled by pulverized coal under controlled gasification conditions so as to produce a clean synthetic gas or syngas which can then be collected and combusted. The pulverized coal is fired into the mechanical cyclone under sub-stoichiometric conditions to gassify the coal. The addition of calcium bearing reagents serve to capture sulfur, while the gasification of the coal produces a combustible syngas that is collected and, with the proper addition of air and recirculated flue gas, fired in another burner. The cyclonic action isolates the particles to the outer edge of the cyclone where they fall and are collected in a hopper, thus collecting particulate as well as sulfur capturing sorbent. The result is the production of a clean burning gas with low particulate emissions and low NOx using coal as the fuel.
