Turkey manure and meat bone have potential uses as fuel in conventional power plants. It is commonly agreed that problems can arise from uncommonly high contents of chlorine, sulfur, and alkali metals in turkey manure and meat bone, including corrosion, fouling, and inactivation of catalysts and membranes. Numerous studies have focused on the reactions of inorganics from combustion and pyrolysis of meat bone, and the thermochemical conversion of turkey manure has been in investigated to a much lesser extent. Gasification techniques of biomass waste (e.g., manure) has been reviewed recently, but the gaseous inorganic species have not been directly determined in high-temperature product gas during the gasification and co-gasification of meat bone and turkey manure. In the present study, turkey manure and meat bone are gasified under temperature conditions of entrained flow gasification (1673 K). The two waste biomasses are used in pure form and in blends with lignite and hard coal. Significant condensable and noncondensable inorganics are detected in situ in the high-temperature gas, using molecular beam mass spectrometry (MBMS).
