WQ型煤粉预燃室旋流燃烧器(以下简称燃烧器)是上海吴泾热电厂与清华大学热能工程系共同研制成功的。它具有点火性能好,稳燃能力强,长时间投用不结焦、不积粉、不烧坏等优点,并配有遥控、程控和自动等装置,故具有投用迅速的优点。在技术鉴定会上,一致认为:该型燃烧器设计合理,结构简单,安全可靠,操作方便以及改造费用少。我厂已在四台高压煤粉炉上使用,投用两年多来表明性能良好,经济效益显著。每台220吨/时高压煤粉炉参加调峰,全年节油1900吨,每次点火可节油3～8吨。一、燃烧器的布置燃烧器在锅炉上布置的位置直接影响能否实现煤粉点火和低负荷稳燃,特别是主燃烧器布置在四角的锅炉,在布置上必须使“燃烧器”与主燃烧器的两股射流在合适的位置相遇。
WQ pulverized coal pre-chamber swirl burner (hereinafter referred to as the burner) is jointly developed by Shanghai Wujing Thermal Power Plant and Tsinghua University Department of Thermal Engineering. It has a good ignition performance, stable combustion ability, long-term use of non-coking, no powder, not burn, etc., and equipped with remote control, program-controlled and automatic devices, it has the advantages of rapid investment. At the technical appraisal meeting, they all agreed that this type of burner is reasonable in design, simple in structure, safe and reliable, convenient in operation and low in modification cost. Our factory has been using four high-pressure pulverized coal stove, cast more than two years to show good performance, significant economic benefits. Each 220 t / h high pressure pulverized coal furnace to participate in peak load, the annual fuel-efficient 1900 tons, each ignition can save 3 to 8 tons. First, the burner layout Burner placed on the boiler position directly affect whether the pulverized coal ignition and low load steady combustion, especially the main burner arranged in the four corners of the boiler, the layout must be “burner” and the Lord The two jets of burner meet in place.
