The invention relates to a pulverized coal boiler hearth soot blower. The pulverized coal boiler hearth soot blower comprises a boiler (13). A burner (14) is arranged at the head of the boiler (13) and provided with a tertiary air inlet (1). A dust remover (7), an induced draft fan (8) and a chimney (9) are arranged at the tail of the boiler (13) sequentially. A tertiary fan (11) is connected between the induced draft fan (8) and the chimney (9). An outlet of the tertiary fan (11) is connected with a tertiary air main pipe (12). A hearth tertiary air main pipe (2) and a soot blowing header pipe (6) are arranged in a hearth of the boiler (13). The tertiary air main pipe (12) is connected with the hearth tertiary air main pipe (2) and the tertiary air inlet (1). The hearth tertiary air main pipe (2) is provided with a hearth tertiary air branched pipe (3). The soot blowing header pipe (6) is provided with a hearth soot blowing device (4). Through the pulverized coal boiler hearth soot blower, the problem that a hearth-in soot blowing pipe is faced with high-temperature melting can be solved, and meanwhile, the original emission value of NOx is lowered effectively.
Description
technical field [0001] The invention relates to a pulverized coal boiler furnace soot blowing device, which is especially suitable for the soot blowing system of the environmental protection industrial pulverized coal boiler, and is mainly used for purging the fly ash at the bottom of the furnace of the boiler. Background technique [0002] The resource characteristics of my country's rich coal, poor oil and little gas determine that coal is the main energy source. For a long period of time in the future, the status of coal as the main energy source will not change. With more than ten years of research and development and practice in my country, the development of pulverized coal industrial boilers has made great progress. Pulverized coal industrial boilers use high-quality, high-activity clean pulverized coal as fuel, which is a backup or substitute for natural gas boilers. Its essential attributes include cleanliness and sanitation, friendly working environment, fully encl...
