Opposed firing boiler is applied in China early and swirl burner is used in 1950s too. The technology of opposed and swirl of America is taken in the early of 1986. Accompanied with B&W's technology is introduced. It brings a great number of new design idea. Such as the method of control steam temperature is accompanied by the combination of Attemperator and gas damper. It is easy to operate and get high efficiency and make adjust flexible and decrease the deviation of the furnace exit gas temperature, at the same time ,it is useful to make pollution lower. But it is not all of America technology to suit for Chinese Market, so it needs us to understand and ferfect.Otherwise, it would block the development of boiler. There are not more details of the test and the numerical for the opposed firing, especially for the large quantity boiler. So there are many questions to be studied completely.It is one of this works that research the performance and operating of Opposed firing boiler. Numerical simulation is dominating part of CAT, also the core of this work. This work which aims to get preliminary study for the opposed firing boiler is based on the principles and the part of operating data by using Computer Aided Test and software FLUENT. The varied loads of the 330MW boiler are calculated, and then compared with operating, both are conducted so as to validate theoretical simulation. The result is in accordance with the operating data well.
