Application of New Type of Low NOx M-PM Burner in 700 MW Unit

doi:10.11930/j.issn.10.11930.2015.4.61

Abstract

Abstract: The applications of Mitsubishi ultra-low NOx burner (the M-PM burner) in two 700-MW subcritical boilers in Zhuhai Power Plant are introduced in this paper. The M-PM burner is newly developed based on the A-PM low NOx burner by Mitsubishi, which is characterized as better ignitability, flame holding performance and impressive effect on NOx emission reduction. After boiler burner retrofitting, while the Shenhua coal is burned in the boiler, the concentration of NOx emission is reduced from 360 mg/m3 to 136 mg/m3, about 62% less than before. In addition, the problems of low boiler steam temperature, large heat deviation of flue gas and high operating angle of burner are solved, and the boiler efficiency is also improved slightly.

Key words: pulverized coal-fired boiler, low NOx combustion, burner retrofitting, M-PM burner
