整体煤气化联合循环（IGCC）发电技术介绍

整体煤气化联合循环（IGCC）发电技术是煤气化和蒸汽联合循环的结合，是当今国际正在兴起的一种先进的洁净煤（CCT）发电技术，具有高效、低污染、节水、综合利用好等优点。它的原理是：煤经过气化和净化后，除去煤气中99％以上的硫化氢和接近100％的粉尘，将固体燃料转化成燃气轮机能燃用的清洁气体燃料，以驱动燃气轮机发电，再使燃气发电与蒸汽发电联合起来。

Introduction for Electricity or Power Generation Technology for Integrated Coal Gasification Combined Cycle

The electricity or power generation technology for Integrated Coal Gasification Combined Cycle is combined cycle for coal gasification and steam, and it is a kind of clean coal power generation technology in world these days, and its advantage is high efficiency, low pollution, sparing water and integrated using etc. The theory： after coal is gasified and cleaned, 99% H2S and near 100% dust in syngas is removed, and solid fuel is changed into clean syngas for gas turbine, and the gas turbine is drove to generate electricity, and at last gas and steam electricity generation is combined.
