为了适应联合循环中燃气轮机功率提高的要求,余热锅炉技术正在迅速地发展。事实上,曾经是简单的余热锅炉,现在与复杂的、和燃气轮机完全结合在一起的蒸汽循环联系起来了。三级压力、为减少氮氧化物(NO_X)喷入蒸汽、汽轮机旁路、提高汽压和汽温、补燃、选择性催化还原、甚至适应煤气化工艺过程都是优秀余热锅炉设计师必须掌握的。为了跟上燃气轮机技术的迅速发展,余热锅炉变得更加复杂。由于燃气轮机的排气
Waste heat boiler technology is rapidly evolving to meet the increased power requirements of gas turbines in combined-cycle applications. In fact, what used to be a simple waste heat boiler is now linked to a complex steam cycle that is fully integrated with the gas turbine. Three levels of pressure, to reduce the nitrogen oxides (NO_X) into the steam, turbine bypass, improve steam pressure and steam temperature, make up the combustion, selective catalytic reduction, and even to adapt to coal gasification process are excellent waste heat boiler designers must master of. In order to keep up with the rapid development of gas turbine technology, waste heat boilers have become more complicated. Due to the exhaust gas turbine
