新建燃煤电厂采用等离子点火装置取消燃油系统的风险分析

Risk Analysis:to Adopt Plasma Ignition Device and Cancel Fuel Oil System in the Newly-built Coal-fired Power Plant

在新建燃煤电厂中采用等离子点火装置,取消燃油系统可以减少设备维护量,也可以减少粉尘排放。但同时也存在一定的技术风险,如机组启动的安全问题、等离子点火系统隔层点火方式、热备用、锅炉再热汽温调节等问题,并提出了相应的预防措施。

In the newly-built coal-fired power plant,to adopt the plasma ignition device and cancel the fuel oil system may reduce the maintenance work of equipment and decrease the discharge of dust,but a certain risk also existes,for example,the reliability problem of unit during start-up,the realization of ignition mode of every other layer in the plasma ignition system, and the regulation of reheat steam of boiler etc,problems.in view of the hidden danger：when the plasma ignition device is adopted,during the cold-state ignition and low load steady-state combustion of boiler,the slagging and burnt-out hidden dangers of burners easily occur,the paper puts forward the matters needing attention in the desiga optinization and debugging of burners,
