In order to reduce flue gas temperature of the boiler and improve economy of thegenerators

adopts thermogravimetry and infrared- spectrum methods to analyze the volatilesseparating law for actual kinds of coals

studies the influence of coal pulverizer temperature upgradeon coal powder combustion capability

verifies the feasibility of coal pulverizer exit temperatureupgrade. The test result shows that: after the coal pulverizer exit temperature upgrade

the operation ofthe coal pulverizers are safe and reliable

reduces standard coal consumption for power generationabout 1.17 g/(kW·h)

saves generators cost about RMB1.282 million yuan a year

brings fine economicbenefits and spread value

can provide reference for the same type of generators.
