微油点火技术在火电厂的应用研究

Application and Research on Micro Oil Ignition Technology in Thermoelectric Power Station

对火电厂微油点火系统的工作原理、系统组成、点火流程进行了分析,阐述了微油点火系统应包括燃油系统、小油量气化油枪、压缩空气系统、高压风系统、电点火装置以及PLC控制系统等主要子系统的作用.为了确保锅炉点火安全,系统的火焰检测采用紫外光加红外光(UV/IR)双路检测,分三个阶段来实现.

Systematic operation principle, system made up, the procedure of micro oil ignition in thermal power plant is analyzed in this paper. Micro oil ignition system should include the fuel system, light a fire on the function of main subsystems such as the device and PLC control system,etc. In order to guarantee ignition of the boiler＇s security, the systematic flame measures and adopts the ultraviolet ray to add one pair of ways of infrared light （UV/IR） to measure flame in three steps.
