Abstract

The Air Blown Gasification Cycle is a power generation system involving the partial gasification of coal in a pressurized fluidized bed gasifier to produce a low calorific value fuel gas and char residue. The cleaned fuel gas is burned in a high efficiency gas turbine to produce electric power. The ABGC and other similar coal burning cycles require gas turbines which can use low calorific value fuel-gas produced during coal gasification. Previous research projects were aimed at providing gas turbine combustion technology which could burn low CV fuel gas satisfactorily with only minor modifications to existing industrial gas turbine hardware. It was apparent, however, that combustion systems based on existing combustor design principles were only moderately effective at controlling the emissions of nitrogen oxides resulting from fuel bound nitrogen. Accordingly, the aim of this project was to develop advanced nitrogen oxide combustors and to test them at approximately half full-scale. An understanding of the processes occurring during the combustion of fuel within the gas turbine combustor was required and therefore mathematical modelling techniques and laboratory scale tests were used to optimize designs. The project adopted integrated development using laboratory scale test facility, modelling and prototype combustor tests.
