摘要

某200MW机组燃用褐煤的HG-670/13.7-HM18型锅炉通过在微油燃烧器内布置双油枪和在高温炉烟风道上加装油枪加热器等

解决了微油点火难的问题。实际运行结果表明

冷炉起动时

在给煤量为2～12t/h范围内

微油燃烧器内煤粉稳定着火和燃烧

锅炉升温升压速率在规程允许范围内。与采用传统的大油枪点火起炉方式相比

节油率可达到76%。

Abstract

The retrofit of a conventional 200 MW unit with HG-670/13.7-HM18 type lignite boiler involving tiny-oil technology is discussed.The burner is equipped with a fan-mill pulverizing system in which the high-temperature flue gas is used as the desiccant.Some features of the existing lignite boiler against the application of tiny-oil technology are realized such as large flow rate of the fan-mill

low concentration of the pulverized coal during cold-starting of the boiler

large size of the primary nozzles

as well as the hexagonal arrangement of the burner.These concerns are successfully addressed by employing a duo-oil-gun arrangement in the combustor and an oil-gun heater in the flue duct.Experimental results of cold-starting of the retrofitted boiler show that

pulverized coal is able to be stably ignited and combusted within the feeding range of 2~12 t/h.Both the steam temperature and pressure rising rates satisfy the requirements of the operation rules.By applying the tiny-oil technology

an oil-saving rate of 76% is achieved.
