Abstract. Utilization of coal gasifiers to power MCFC requires a cleanup system to remove sulfur and particulates. Of the two near term options available for desulfurization of gasifier effluent, namely low temperature cleanup utilizing absorber/stripper technology, and hot gas cleanup utilizing metal oxides, there is a clear advantage to using hot gas cleanup. Circulating Moving Bed (CMB) combustion technology has its roots in traditional circulating fluidized bed technology and involves a novel method of solid fuel combustion and heat transfer. CMB technology represents a step change in improved performance and cost relative to conventional PC and FBC by: 1. A major part of the DOE effort in the Office of FE is directed toward development of coal-fired electric power generation systems. The DOE program sponsors coal technology development from basic research through engineering, proof-of-concept testing, and . In the combined cycle design (Fig. ), the flue gas from the PFBC boiler enters the hot gas clean-up system at about °F. After passing through the hot gas clean-up system and expanding in the gas turbine generator, the flue gas passes through a heat recovery steam-generator and conventional bag-house or ESP filter.
Granular moving bed filters and adsorbers (GM-BF/A) for hot gas cleanup continue to be developed as a key component of current integrated gasification combined cycle and advanced pressurized. The goal of this study was to evaluate the performance of a moving bed granular filter designed for hot gas clean up. This study used similitude theory to devise experiments that were conducted at. 1.

Variables analyzed are equivalence ratio (from to ), temperatures of the gasifier bed (− °C) and of its freeboard (− °C), H/C ratio in the feed, use of secondary air (10% of the overall) in the freeboard, and addition (2−5 wt %) of a calcined dolomite mixed with the biomass Cited by: Abstract. After a decade of extensive research, a number of solid sorbents have been identified as being suitable for the high-temperature removal of H 2 S from coal gas.
