摘要

目前

亟需对燃气轮机机组燃烧过程进行有效控制和优化以控制NO_x排放。本文以德国西门子SGT5-4000F(4)重型燃气轮机为研究对象

考察了简单循环燃烧过程中不同燃气轮机负荷下空气系统、燃料系统、燃烧系统和排气系统各参数对NO_x排放的影响规律。结果表明:压气机压比、进口可调导叶(IGV)阀位、燃烧室差压随燃气轮机负荷变化呈特定线性变化关系

值班气流量和透平排气温度是影响NO_x排放的重要参数;当燃气轮机负荷低于110 MW时

NO_x排放质量浓度随负荷增加而增加;当负荷高于110 MW时

NO_x排放质量浓度随负荷增加迅速降至最低值后逐渐增加至趋于不变。

Abstract

At present

there is an urgent need to effectively control and optimize the combustion process of gas turbine units to control NO_x emissions. Taking a Germany Siemens SGT5-4000 F(4) heavy duty gas turbine as the research object

the influences of the parameters of air system

fuel system

combustion system and exhaust system on NO_x emissions at different loads during a simple cycle combustion process are studied. The results show that

the pressure ratio of compressor

IGV valve position and differential pressure of combustion chamber vary linearly with the load of the gas turbine. The pilot gas flow and the turbine exhaust gas temperature are the important parameters that affect NO_x production. When the gas turbine load is lower than 110 MW

the NO_x emission concentration increases with the gas turbine load. When the gas turbine load is higher than 110 MW

with the increasing of the gas turbine load

the NO_x emission concentration rapidly decreases to the lowest value and then gradually increases to the constant.
