The application and research results of the small oil gun on the boiler with exhaust pneumatic pulverized coal convey system and its role of energy saving are analyzed and discussed,and its practical application results are given.

1 boiler working conditions over the years,this paper analyzes the effects of different operating modes of vent pulverized coal handling system on the air and heat exchange of the air preheater.

Numerical Simulation of Aerodynamic Field in the Whirl Burner of a Pulverized Coal Fired Boiler;

Characteristics of mercury emission and demercurization property of NID system of a 410t/h pulverized coal fired boiler;

Making use of the oxygen-film enrichment technology,an experimental study on combustion-supporting technology,by local oxygen enrichment,has been conducted on a 150t/h pulverized coal fired boiler.

For reducing NOx emission of six point tangential burning PC(pulverize coal) boiler firing lignite coal, the paper describe the test study of NOx emission of one 670t/h PC boiler firing lignite coal after it was modified with horizontal lean-rich combustion and air stage feeding technology.

For problems of low heat efficiency and serious inadequate output of 211-75/39 type PC boiler, reasons were analyzed and technical retrofit using PW-Ⅰ PC burner was carried out.
