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.
