Multi-stage desulfurizing fluid-bed combustor for coal-fired hot gas generator systems. Topical report No. 1
This report covers the design, fabrication and preliminary testing activities of the COHOGG program. The COHOGG system contains a pyrolyzer for partial gasification of the coal through sub-stoichiometric combustion, a char burner which burns the char (generated in the pyrolyzer) in excess air, and an afterburner where the pyrolyzer gases and char burner gases meet to produce a high temperature (approx. 3000/sup 0/F) environmentally clean flame capable of replacing an oil or gas blue flame burner. The system fabrication is complete and preliminary tests results have demonstrated a stable afterburner flame at a temperature up to 1800/sup 0/F with cold air from the char burner side. The char cyclone efficiency is in excess of the 95% required. The char burner has been successfully operated on coal. Initial pollution measurements to be undertaken in the next task will entail operation of the pyrolyzer and char burner together.
