The Research And Application Of Minimal-Oil Igniting Pulverized-Coal Burners At Jiaxing Power Plant

It is very important for China to reduce the consumption of petroleum under the pressure of its fundamental realities of lean-oil-rich-coal and the consistently increasing price of international crude oil. For this reason, we developed series of minimal-oil igniting burners applied on the boilers in power stations to reduce the oil consumption for ignition. The most significant characteristic of the burners is the average igniting-oil reduction by over 95%. This superior performance can be assured by some built-in igniting oil nozzles and by some novel designs for the burners' cooling. The application of this technology on a 600 MW unit shows the igniting-oil consumption reduced from 631 tons to 11 tons. Up to now, the technology has achieved remarkable success on over 50 power units in China.
