摘要
Abstract
The issues such as W-flame boilers with poor combustion stability and poor burnout were investigated by using numerical simulations and experimental measurements. The modification and combustion optimization technology schemes were developed according to the technology characteristics of three types of W-flame boiler. For the Foster Wheeler (FW)-type boilers, some burners were closed at high boiler loads and a novel integrated scheme consisting of below-arch air direction adjustment and above-arch air distribution optimization was put forward. For the Mitsui Babcock Energy Ltd. (MBEL)-type boilers, a kind of new technology with the improved slit burners and below-arch secondary-air direction adjustment was proposed to improve the boiler performance. For the Babcock & Wilcox (B&W)-type boilers, a kind of dual channel swirl burner combining with above-arch secondary air adjustment method was used. And then, after application, the boiler combustion stability and economical performance are greatly improved, and the pollution emissions are reduced. Based on the above-mentioned work, a physical model and optimization design guidelines were proposed to improve the boiler performance according to limited space jet moment of momentum conservation.关键词
