abstract

The pulverized coal burner is widely used in industry, especially in electricity industry. Stable combustion of the burner is very important to conserve energy and minimize environmental impact. Generally, most of gas or oil will be consumed when the burner is ignited. Meanwhile, the operation of the dust catcher will be affected when oil is burned in the furnace which leads to more emission of solid particle into the air. Tiny-oil ignition burner can be a solution to the above problems. The structure of burner should be different for fuel and each different application. It is a challenge to optimize the structure of burner. Three-dimensional CFD simulations were performed to optimize the design of a tiny-oil ignition burner. The temperature distributions along the central line of the tiny-oil ignition burner show that the structure of the oil combustion chamber and the first combustion chamber are worthy of optimization based on the type of Chinese coal.
