Cycle System

Up to now, gas turbines have mainly been built for use with liquid fuels or natural gas. For the new combined cycle system with integrated coal gasification, the quality of the feed gas has to match the requirements of the gas turbine, which is particularly important for high-efficiency gas turbines. The paper describes a combined cycle system with integrated PRENFLO coal gasification and, in particular, the treatment of the gas produced by the gasifier. This power plant concept — a highly integrated plant — is a joint development of Siemens/KWU and Krupp Koppers. Our coal gasification is based on the entrained-flow principle with dry coal dust feeding.

Shell And Tube

A shell-and-tube heat exchanger which is widely used for the heat recovery of air in a coal gasification system is investigated. FLUENT6.3 software is used and the RNG k−ε turbulence model is adopted for modeling turbulent flow. The porosity rate, the distribution of the resistance and the distribution of the heat source were introduced to FLUENT by coupling the user defined function. The variation of local heat transfer is studied under the effects of the baffles arrangement. The result shows that the porous media model can be applied in shell side of the air cooler in IGCC and the reasonable arrangement of the baffles can decrease the pressure drop with little influence on the heat transfer.

The attraction of a coal gasification combined cycle system to utility operation lies in its higher efficiencies (pile-to-busbar) relative to competing power generating systems. In order to achieve these higher efficiencies the coal gasification combined cycle combustor/turbine section must provide reliable operation with low or medium Btu gaseous coal derived fuel at turbine inlet temperature levels above 2600°F. Utilization of low Btu gas (LBG) fuel for attainment of temperature levels up to 3000°F in a gas turbine combustor environment presents several unique design and development problems. Because of the extremely high stoichiometric ratios required to attain 3000°F, the management of combustor cooling as well as internal air and low Btu gas fuel flow mixing patterns is considered critical for high combustion efficiency and stability. Equally important is the requirement for long term combustor durability. A unique combustor design concept has been developed to utilize the available heat sink capability of the LBG fuel to adequately cool the combustor walls for long service life. Under a U.S. Department of Energy contract, an LBG fuel cooled combustor was designed for operation with 150 Btu/SCF fuel for use in development of a turbine capable of operating at 3000°F. This paper describes the background combustor technology and test program results with 150 Btu/SCF fuel regarding the combustion stability, efficiency, emissions and burner wall temperature levels for operation up to 3000°F exit gas temperatures and 6 atmospheres.
