摘要

初步设计了一种采用烟气循环富氧燃烧的微型燃气轮机燃烧室

按燃烧稳定、总压恢复系数、出口温度场调节等几个方面确定燃烧室基本的几何尺寸

二次风及掺混冷却孔的位置

旋流燃烧器的结构等

并利用CFD软件对设计燃烧室的热态流场、燃烧稳定性、燃烧效率、压力损失等性能进行了数值模拟。计算结果表明

设计的燃烧室流场合理

燃烧稳定、效率高

压力损失小

基本达到了设计要求。

Abstract

A new oxygen-enrich combustion chamber of micro gas turbine running with flue gas circulating was preliminary designed.The basic geometric dimension of the combustion chamber

the location of the secondary air and mixing cooling hole

and the swirl burner's structure were designed to meet the requirements of high combustion efficiency and stability

total pressure recovery coefficient

outlet temperature field regulation and other aspects.Besides

the CFD software was used to study the performance of designed combustion chamber

like hot flow field

combustion stability

combustion efficiency

pressure loss and so on.The results show that

the combustion chamber has reasonable flow field

stable combustion

high combustion efficiency and small pressure loss

which basically satisfies the design requirements.
