作为煤炭需求大国，为更加有效清洁的利用煤炭资源，提高电厂安全运行效益和发电效率。采用三维物质点法，利用Mathematica构建包含锅炉、风、煤粉的三维物质点模型，并针对飞灰与锅炉壁的粘附过程，针对不同内/外二次风旋流强度与煤粉颗粒粘附数目的关系进行仿真模拟，注重分析个中机理，为锅炉改造、煤粉使用提供理论依据。
Abstract
As a big country of coal demand,in order to use coal resources more efficiently and effectively,improve the safety operation efficiency and power generation efficiency of power plant.This study uses the newly-develop method-three dimensional material point method,builds three dimensional material point model that include boiler,air and coal powder by MATHEMATICA,carries on emulation simulation of the adhesion process of fly ash and boiler wall,the relationship between the different inner/outer secondary air swirling intensity and the number of adhesion of coal powder particles,pays attention to the analysis of the mechanism,as to provide a theoretical basis for the transformation of the boiler and the use of coal powder.
