- W2354839192 abstract "W-shaped flame boiler is especially suitable for the electricity generation using low-volatile and poor quality coal,owing to the particular structure of the furnace and flue gas flow characteristics.The air distribution and coal particle has great effect on forming favorable combustion in the furnace of W-shaped flame boiler.The air distribution and coal particle has also great effect on ensuring boiler's safe,high-efficiency and clean burning.RNG k~e model and DPM model were used to simulate the three-dimensional flow field and the flowing trajectory of coal particle at different operating conditions of a 300MW W-shaped flame boiler.The simulations of flow field were implemented at different air distribution and different diameter of coal particle.The results indicate that the air distribution has great effect on the symmetry of W-shaped flow field in furnace.The flame will be short circuit when the primary air is too small.The bottom ash hopper will be eroded by the flue gas flow when the secondary air is too large.Because of the nose of the furnace,symmetrical air distribution can not form symmetrical flow field.The increase of the second air velocity on the front wall can decrease the effect of the nose of the furnace.The symmetry of flow field is best when the velocity ratio of the front wall to rear wall is 1.05.The double vortexes flow structure forming in the bottom ash hopper can enhance the heat transfer and mass transfer of coal flow.The vortexes can also increase the residence time of coal particle in the combustion chamber and be in favor of the burnout of coal.The diameters of coal particle are very important to the flow and combustion in W-shaped flame boiler.The average depth of coal particle going into the furnace increases with diameters of coal particle increasing.With diameters of coal particle increasing,the average residence time of the coal particle in the furnace increases until to a maximum value,and then decreases.An optimal diameter of coal particle exists for a W-shaped flame boiler.The study results are great significant for the design of large-capacity boiler and combustion adjustments of W-flame boiler." @default.
