Energetic analysis and optimisation of an integrated coal gasification-combined cycle power plant

Abstract

Methods are presented to analyse and optimise the energetic performance of integrated coal gasification-combined cycle (IGCC) power plants. The methods involve exergy analysis and pinch technology and can be used to identify key process parameters and to generate alternative design options for improved energetic efficiency. The methods are demonstrated by analysing the initial design of a 600 MW¢ IGCC power plant based on the Shell coal gasification process.

Exergetic evaluation of biomass gasification

“…It was previously demonstrated by Vlaswinkel [3] for gasification of coal and recently by Ptasinski et al [4] for gasification of organic sludge that the gasifier is one of the least-efficient unit operations in the whole gasification technology. Therefore, an analysis of the gasifier alone can substantially contribute to the efficiency improvement of the whole gasification technology.…”

Microstructural and mechanical evaluation of porous biomorphic silicon carbide for high temperature filtering applications

“…[1][2][3][4][5] An essential process of these technologies is the expansion of hot pressurized gas through a gas turbine. Although these technologies are the cleanest and most efficient options for generating electricity from coal and carbonaceous waste materials, they require varying degrees of development and validation before being connected to power distribution grids.…”

Application of the TG-MS system in studying sewage sludge pyrolysis and gasification

“…The synthesis gas and inert ash are the products of this process -gas can be utilized for power generation or chemical syntheses 2,3,4 . Gasification of coal is a well-known process and has been used for many years 5 , but the gasification of sewage sludge still needs further investigations 4,6 . The aim of this work is to demonstrate a monitoring method of sewage sludge pyrolysis and gasification processes.…”
