摘要:
采用冷态模拟实验与数值计算相结合的方法对贾汪PFBC-CC中试电站旁路烟道的减温器进行了专门研究设计.提出的高速文丘里雾化冷却器与小孔型节流降压消音器相结合的减温减压装置在中试电站的成功运行表明,采用高速文丘里雾化冷却方式能够充分利用高温高压烟气的能量雾化冷却水,既能使大气量的烟气快速降温,又能确保烟气的干度,安全地实现不同工况下含尘烟气的减温减压排放.这种新方法解决了高温高压含尘气流的结构简单、紧凑、安全排放的问题,可应用于诸如燃煤联合循环发电系统以及石油、化工等领域高温高压含尘烟气旁路减温减压装置的设计中.
Abstract:
The attemperator of the gas bypass of Jiawang PFBC-CC pilot plant was studied by simulating experiment and numerical calculation. The successful practical operation of the pilot plant shows that the venturi spray attemperator can atomize cooling water by using energy from high-temperature and high-pressure gas. It can make large numbers of gas attempered to temperature required rapidly and ensure the cooling water to vapor and overheat completely avoiding the depressurizer of minute orifices’ blocking. The attemperator combined with the depressurizer also can meet operation requirement under variant loads. This new method provides a compact, economic and reliable way to discharge the high-temperature and high-pressure gas with particles, and can be applied in coal-fired combined cycle power generation system and petrochemical and chemical engineering.
