Study and Application of Low NO_x Combustion Technology in Tangential-Firing Pulverized Coal Boiler

Numerical simulation of the NOx emission in the 300 MW tangentially pulverized coal fired boiler was performed using the software of COALFIRE based on TASCFLOW software platform.

Numerical simulation of the characters of unburned carbon in fly ash on the 300 MW tangentially pulverized coal fired boiler was performed by the numerical simulation software COALFIRE.

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.
