Biomass power generation is attracting more and more attention because its nearly net zero emission of carbon dioxide and its high fuel flexibility. Compared to coal, biomass has lowemission of SOx and particulate matters from the combustion process because its low sulphur and ash content. So biomass utilization played a significant role in the development of environmentally friendly society. Grate-fired boiler coal fired power plant chiang mai has the advantages of lOW investment cost and high ruel flexibitity and it iS the main technology of biomass power generation and heat supply. In this paper, numerical similation of the flow field Was carried out with FLUENT software for double—grate biomass fired boiler, the results were validated by experimental data taken from a 1/30 scale cold model of the prototype.

First, because the ash, sulfur and nitrogen content in the gas are lower than those in coal, the amount of dust in the flue gas produced after combustion is very small, and the flue gas discharged can easily meet the national standards for combustion equipment. The use of gas-fired boiler coal fired power plant chiang mais can greatly reduce environmental pollution.

China Association of boiler coal fired power plant chiang mai and boiler water treatment boiler technology plays in the development of healthy and clean technology development and lead the industry in an important position, and boiler manufacturers are inseparable, in the future, the Group will soon square to maintain good communication with the Association to promote the technological innovation industry, enhance the technological level of the industry, promote the vigorous development of the boiler industry to contribute their efforts.

The first half of the boiler coal fired power plant chiang mai end of the oven wood oven, after completion of the coal oven according to the requirements, at this time, should increase the degree of opening of the blower, draft fan slightly open, close the door, ash door, to further improve the smoke temperature, to bake the purpose of the dry furnace wall.
