Abstract<br>This design is the design of ventilation and dust removal system, desulfurization system and ventilation system of thermal power plant. Through the analysis and calculation of the flue gas generated by the boiler, the comprehensive consideration of all aspects is carried out, and the bag type dust collector is selected as the dust removal device. The structure of packed tower and spray device is designed in desulfurization system. The chimney shall be designed in accordance with class II area standard, smoke concentration emission standard and carbon dioxide emission standard in the emission standard of air pollutants for boiler (gb13271-2001). The specification of the pipeline system is determined by the parameters of the flue gas. Through the calculation of the resistance of the pipeline system, the resistance of the dedusting system and the resistance of the chimney, the total resistance of the system is obtained. According to the calculated air volume and air pressure, the fan is selected according to the actual process and economic considerations, and the fan is calculated.<br>Key words: bag type dust removal and desulfurization fan of thermal power plant<br>
