The research and development and application of minimal-oil igniting pulverized-coal burners

Abstract

Paper presented at the 6th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 30 June - 2 July, 2008.It is very important for China to reduce the consumption of petroleum under the pressure of hers 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 ignitingoil reduction by over 95%. This superior performance can be assured by some built-in igniting oil guns and by some novel designs for the minimal-oil burners. Up to now, the technology has achieved remarkable success on over 30 power units in China.
