中文摘要: 某燃气轮机作为联合循环电厂的主发电装置，以天然气为燃料，度电成本为0.720元/(kW ? h)。为 了降低该燃气轮机的度电成本，提高运行经济性，拟改用焦炉气为燃料。本文通过计算，得出以焦炉气为燃 料的度电成本仅为0.350元/(kW ? h)，比使用天然气为燃料的度电成本降低了 51.4%。进而为了实现燃气 轮机由天然气改烧焦炉气，依据燃料特点提出了四种适用于焦炉气的喷嘴结构，并分别对燃烧性能进行了数 值模拟，选出最优设计方案，并且优选出的喷嘴理论数据基本接近原天然气喷嘴的试验数据，为进一步开展 焦炉气喷嘴燃烧综合性能试验奠定了基础。
Abstract:A gas turbine is used as the main power generation unit of a combined cycle power plant，using natural gas as fuel，and the
cost is 0. 720 yuan / ( kW · h) . In order to reduce cost and improve economy，coke oven gas is proposed to be used as fuel. The cost of the gas turbine using coke oven gas as fuel is only 0. 350 yuan /( kW · h)，which is 51.4L lower than that of natural gas. Then， in order to realize the change of gas turbine from natural gas to coke oven gas，four kinds of nozle structures suitable for coke oven gas
are proposed according to the characteristics of fuel，and the combustion performance is simulated respectively，and the optimal design
scheme is selected. The theoretical data of the optimized nozzle is basically close to the experimental data of the original natural gas
nozzle，which lays a foundation for further comprehensive performance test of coke oven gas nozzle.
