    数控锅炉的燃烧和烟风系统在燃烧和烟风系统方面,送风机将空气送入空气预热器加热到一定温度。在磨煤机中被磨成一定细度的煤粉,由来自空气预热器的一部分热空气携带经燃烧器喷入数控锅炉的炉膛。数控锅炉的燃烧器喷出的煤粉与空气混合物在炉膛中与其余的热空气混合燃烧,放出大量热量。燃烧后的热烟气顺序流经炉膛、凝渣管束、过热器、省煤器和空气预热器后,再经过除尘装置,除去其中的飞灰,最后由引风机送往烟囱排向大气。
    The combustion and smoke exhaust system of the numerical control boiler is in the aspect of combustion and smoke air system, the air blower sends the air into the air preheater to heat up to a certain temperature. Is ground to a certain degree of fineness of pulverized coal in the coal mill, carried by the air preheater from a portion of the hot air through the burner into NC boiler furnace. The combustion of pulverized coal and air mixture in the burner of the numerical control boiler is mixed with the rest of the hot air in the hearth, and a large amount of heat is released. The furnace, slag bundle, superheater, economizer and air preheater hot flue gas flowing through the sequence after combustion, after dust removal device, the fly ash removing them, finally by the fan to the chimney into the atmosphere.
