Coal-water slurry

       Coal-water slurry is a new coal-based liquid fuel that emerged from the 1970s, consisting mainly of 65% coal, 34% water and 1% chemical additives. Compared with other types of fuel, it has many advantages, such as low sulfur content, high combustion efficiency, SO2 and NOX and other pollutant emissions are lower than ordinary fuel and coal, is widely used in power plant boilers, industrial boilers And industrial kiln on behalf of the oil, on behalf of the gas, coal on behalf of the coal, is an important part of today's clean coal technology. The cemented carbide nozzles are widely used in coal-water slurry burners, which result in a more efficient and efficient combustion of coal-water slurry through good fuel atomization. Depending on the nature of the fuel and the requirements for the quality of the atomization, the cemented carbide nozzle can also be divided into pneumatic, mechanical, rotary cup and ultrasonic. The rationality of its structure determines the atomization effect of CWS, the anti-wear and thermal shock resistance of the material determines the service life of the nozzle and directly affects the economy and safety of the CWS application.
