This paper discusses the use of laboratory drag measurements and filter operating data to analyze factors affecting dustcake flow resistance in a hot-gas filter at the Power Systems Development Facility (PSDF). The hot-gas filter is a Siemens-Westinghouse two-tier candle filter system that is collecting coal gasification ash from a KBR Transport Gasifier. Operating experience with this system h...

Introduction The goal of this project is to develop models that predict accurately coal and biomass gasification and combustion behaviors in the type of environments likely to be established in advanced energy systems. This requires acquiring the information needed to understand and characterize the fundamental chemical and physical processes that govern coal and biomass conversion at high temp...

Since solid oxide fuel cells (SOFC) produce electricity with high energy conversion efficiency, and chemical looping combustion (CLC) is a process for fuel conversion with inherent CO2 separation, a novel combined cycle integrating coal gasification, solid oxide fuel cell, and chemical looping combustion was configured and analyzed. A thermodynamic analysis based on energy and exergy was perfor...

The optimal design of an energy polygeneration system that converts coal and biomass to electricity, liquid fuels (naphtha and diesel) and chemical products (methanol) with CO2 capture under different economic scenarios is investigated. In this system, syngas is produced by gasification of coal and/or biomass; purified by a cleaning process to remove particles, mercury, sulfur and carbon dioxid...

The techno-economic aspects of coal drying with cost effective waste heat recovery mechanism is one of the challenging issues faced while using lignite or high ash brown coal for direct combustion in coal fired thermal power plant. Coal being hygroscopic in nature, re-adsorbs considerable moisture even after conventional drying post wet coal washing condition affecting boiler performance. Parti...

In this paper, effects of the operating pressure on ash formation reported in the open literature have been reviewed. In particular, the recent significant advances achieved at the Cooperative Research Centre for Coal in Sustainable Development (CCSD) in Australia are highlighted. The operating pressure significantly influences the size and the chemistry of ash generated through its effects on ...
