Modernization of Air-Blown Entrained-Flow Gasifier of Integrated Gasification Combined Cycle Plant

... efficiency of a combined cycle and the availability of systems for deep purification of syngas before combustion allow for the study of combined-cycle gas turbines as a promising solution to increase the efficiency and environmental friendliness of coal power engineering. The key element of the device is a gasifier. A Mitsubishi Heavy Industries gasifier is selected as an initial design for modernization, which consists in heating the blast air up to 900°C and supplying vapor with a temperature ...
