The main contents of the present paper include: 1、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.

In order to develop and modify Gregory scheme for cumulus convective parameterization,we make the improvement as follows:(1) The large-scale moisture convergence is taken into account and the organized inflow,which occurs in the area of large-scale moisture convergence and is directly proportional to it, is added to turbulent airflow.(2) The influence on saturation vapor pressure exerted by supercooled water is taken into account and the initial mass flux is adjusted. Based on diagnosis of the air heating and moistening, the downdraft airflow is adjusted.(3) Based on the character of our country heavy rainfall,which usually occurs in the mixed cloud consisted of stratocumulus and cumulus, the process of excessive convection is restrained by organized outflow in the top of cloud and improving downdraft current and by reducing the evaporation of rainfall and release of latent heat.
