【Abstract】 As it is difficult to measure the flue gas flow of boiler in power stations, a on-line soft-measuring model based on easy measured parameters is proposed. Although the model is obtained by air-preheater, it can also be used for other objects in flue gas path of the boiler. With the industry computer and IDCB-893 devices, the distributed data acquisition system can be used for real industrial process.更多还原
