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.

The boundary of analytical model and statistical model is clearly divided in this performance model, and evaluation accuracy is improved. Secondly, based on embedded SRAM performance hybrid model, this article adopts bionics algorithm-ant algorithm to optimize hierarchical embedded SRAM structure. This method which adjusts memory system structure improves memory system performance. Finally, considering the factors such as memory cell area, power, delay and reliability, this article establishes static 6-T memory cell area, power, delay and static noise margin equations, analyzes 6-T memory cell device dimension constraints under "read upset" and "write upset", then proposes a method to enhance embedded SRAM performance by optimizing 6-T memory cell size. In order to realize embedded SRAM design and verify proposed optimization methods, this article takes the Garfield202 system chip as the platform, which embeds A720T processor and 20KB Scratch-Pad memory.
