description | The authors consider the technique based on application of air heated in periodic regenerative ceramic heat exchangers by coal powder combustion products as a gas-turbine working medium to be rather promising for being studied. In this case the working medium can be heated to essentially higher temperatures than at coal combustion in the pressurized fluidized bed. Here only a small amount of ash contained in the coal combustion products settles in the ceramic heat exchanger and then penetrates into the heated air. It allows supporting high air temperature before the turbine at an acceptable level of ash concentration at gas turbine inlet. To substantiate the efficiency of this technique the authors have developed the technological scheme of coal-fired combined cycle plant with gas-turbine cycle working medium heated in periodic regenerative heat exchangers; the mathematical models of regenerative ceramic heat exchangers with cylindrical conduits and coal-fired combined cycle plant were developed. The paper introduces the results based on a detailed mathematical model of the optimization technical and economic studies of coal-fired combined cycle plant with gas-turbine cycle working medium heated in periodic regenerative heat exchangers. |
