Problems commonly occur when the coal type and/or the load are changed in utility boilers. To solve these problems, a new pulverized coal burner, namely, a burner with continuously variable concentrations of coal dust by using a set of blades, is developed in this study. Gas-solid twophase flow downstream of the burner was measured by three-dimensional particle dynamics anemometer (3D PDA). The results show that the particle concentration biased degree of the burner can be continuously adjusted between 1 and 3 by changing the angle between the blades and the primary air flow, over a range of 0-20

Numerical modeling of a front wall pulverised coal fired utility boiler is presented in this paper. Comparison between the pre-dictions and measurements in the boiler is addressed. The accordance of the calculation results with the experimental data at several operating conditions validates the models and algorithm employed in the computation. The need to improve burner or boiler design with the objective of producing Nox abatement while avoiding some negative side effects is also the motivation for the prediction of furnace performance for different boiler operating conditions. The predicted results also lay a foundation for the boiler operating expert system

The text of a paper should be preceded by a summary in English. This should be short, but should mention all essential points of the paper.
