A brief description of the various processing plants within an integrated gasification combined cycle (IGCC complex) is given below in reference to the block flow diagram (Figure 2) discussed under Typical IGCC Configuration. A more detailed discussion of each of the processing plant functions is available; links are embedded in the following discussion.

Waste Heat Boiler - an overview | ScienceDirect Topics

Heat absorbed by water = 0.95 Vs(t 1 t 2)MJ s 1. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2 the temperature at which the flue gases leave the boiler may be reduced to ca.50 K above the temperature of the water in the boiler.

Integrated Gasification Combined Cycle (IGCC) - Global ...

An Integrated Gasification Combined Cycle (IGCC) is a technology that aims to extract the maximum energy out of a fuel that is burnt.In the case of coal the carbon conversion efficiency in an IGCC plant is higher than that in a conventional pulverised coal (PC) fired power plant.This is achieved by gasification which converts coal into synthetic gas or syngas.

Waste Heat Boiler - an overview | ScienceDirect Topics

Heat lost by hot gases = V s ( t 1 t 2) MJs 1 where V = m 3 gas/sec s = specific heat (volume basis). Heat absorbed by water = 0.95 Vs ( t1 t2 )MJ s 1 t1 and t2 = temperature of hot gases before and after the W.H. boiler °C. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler.
