Numerical Simulation of Three-Dimensional Temperature Distribution in the Supercharged Boiler Furnace

Abstract:

In this paper, the visualization of three-dimensional (3-D) temperature distributions in the supercharged boiler furnaces from radiative energy images captured by multiple charge-coupled device (CCD) cameras mounted around the furnace is studied numerically for the first time. The combustion of supercharged boiler is analyzed by structuring a full-scaled model and grid partition. The calculation of the radiative energy image formation is a fast algorithm based on the Monte Carlo method and the two-color temperature calculation method. For the inversion of the 3-D temperature distributions, a modifiedregularization method is used. The simulation results show that: even though the measurement error of the radiative energy images for the 3-D temperature distributions up to 0.12, the position of the reconstruction high-temperature zone is almost the same to the one of the simulation. The results indicate that the reconstruction quality is satisfactory, and the method can lead to a good visualization result.
