Typical Component

Based on the increased attention to “energy security” and “sustainable development”, it is essential to promote clean use of coal as a fuel. Typical advanced technologies are demonstrated by the pressurized fluidized-bed combined cycle (PFBC) and integrated gasification combined cycle (IGCC). Focusing mainly on these two examples as the advanced energy conversion technology, related problems are reviewed. The PFBC technology is a composite technology of conventional fluidized bed and combined-cycle, in which ash, being a typical component of coal, is not melted but is removed mainly in the fluidized bed. On the other hand, the IGCC is much more complicated and ash removal is conducted by melting in the combustor. Heat released there is utilized for gasification process in the reductor installed just downstream the combustor. Even though both systems have very high potential for clean and efficient use of coal, the commercial plants are limited in a very small number or at the stage of just a demonstration plant. To extend and develop clean-coal technology in the electric power generation market, a strategy of the government on the energy technology as well as the long-term competition in the market are indispensable, otherwise related technologies as well as the engineers involved will be lost.

Pulverized Combustion

Power generation in Europe and elsewhere relies heavily on coal as the source of energy and this reliance will increase in the future as other fossil fuels become progressively more expensive. The existing stock of coal-fired power stations mainly use pulverized fuel boilers and present designs based on ultrasupercritical steam cycles are as efficient and as low in SOx and NOx emissions as is possible without incurring excessive additional costs. This paper examines the options for coal-based power generation technologies and compares their technical, environmental and economic performance. These options include atmospheric and pressurized fluidized bed combustion and a range of integrated gasification combined cycle systems. Integrated gasification combined cycles give good efficiency and very low emissions, but further optimization is required to make them economically attractive. Conceptual cycles based on pressurized pulverized combustion, dual fuel hybrid cycles, fuel cells and magnetohydrodynamics are also covered in outline.

The Impact

This paper investigates the performance of a new power cycle, a so called Evaporative Biomass Air Turbine (EvGT-BAT) cycle with gasification for topping combustion. The process integrates an externally fired gas turbine (EFGT), an evaporative gas turbine (EvGT) and biomass gasification. Through such integration, the system may provide the potential for adapting features from different advanced solid-fuel based power generation technologies, e.g. externally fired gas turbine, integrated gasification combined cycle (IGCC) and fluidized bed combustion, thus improving the system performance and reducing the technical difficulties. In the paper, the features of the EvGT-BAT cycle have been addressed. The thermal efficiencies for different integrations of the gasification for topping combustion and the heat recovery have been analyzed. By drying the biomass feedstock, the thermal efficiency of the EvGT-BAT cycle can be increased by more than 3 percentage points. The impact of the outlet air temperature of the high temperature heat exchanger has also been studied in the present system. Finally, the size of the gasifier for topping combustion has been compared with the one in IGCC, which illustrates that the gasifier of the studied system can be much smaller compared to IGCC. The results of the study will be useful for the future engineering development of advanced solid fuel power generation technologies.
