In this paper, the strength theory is adopted to analyze the stress of the pressure component of boiler, and the calculation method of metal fatigue and creep is adopted to estimate the life loss of the boiler. Meanwhile, the short-cut calculation method is put forward which can meet the requirement of on-line monitoring. On the basis of above, the on-line monitoring and management system of boiler life is developed.

The main contents of the present paper include: 1情侣黄色网站免费看、The mechanism of fouling accumulation and the effects of fouling and slagging on boiler performance are analyzed. The model of fouling increasing is developed on the basis of sediment rate and denudation rate. The fouling monitoring models for boiler furnace and convective sections based on heat balance, the ones for air heater based on converted pressure difference are given. The implement results show that these models can reveal the cleanliness of boiler heat transfer surface. 2、The disadvantages of the model for boiler furnace fouling and slagging monitoring based on heat balance are discussed, and the calculation of radiant heat flux is considered as the primary difficulty.
