Since 1025 t/h boiler with PAX swirl burner puts into operation in Pucheng Power Generation Co.

With the Renormalization Group Algebraic Stress Model (RNG ASM), a cold numerical simulation of the flow field of PAX burner is carried out.

Research and application of petal flame stabilizer-a new type swirl burner;

Evolution of low NO_x swirl burner;

Based on strengthening the hot recirculation air and improving concentration of pulverized coal,the mechanism of combustion stability of swirl burners is analyzed and the stable combustion measure of existing swirl burners both at home and abroad are classified.

Application testing and study of plasma combustion technology in coal-fired boiler with double inlet and outlet tube mills and direct whirl burners;

The boiler is fitted with whirl burners,developed by ourselves,inserted in the furnace s front and back wall,opposing each other.

A set of mathematic model on the heat transfer is presented for the whirl burner, and its numerical solution is utterly consistent with the measured results.

The paper reports on study results on Shizuishan power plant’s cyclone burner, by analyzing its existence in base ash containing large quantities of unburned black pieces,probably 10% of base ash.

Based on the stable testing and tuning experiences of radial thick-thin type cyclone burners, the authors analyse the cause that the combustion can t cutoff oil under rated load and propose some measures for stable combustion enabling the boiler stable combustion under 70% full load.

The aerodynamic field of CWS swirling burner was numerically simulated.

To learn the performance of the boilers with swirling burners,numerical simulation was used to analyze and calculate the flow field in the furnace of the boiler.

Fluent CFD software is used to make flow simulation on the flow field of swirling burner;and the distribution of turbulent kinetic energy,backflow field,flown line are drawn from the result of simulation.
