Способ относится к сжиганию пылевидного твердого топлива и может быть использован в теплоэнергетике, промышленных котельных и огнетехнических установках других отраслей. Преимуществом изобретения является снижение выбросов оксидов азота и механического недожога топлива. Это достигается путем регулирования расхода пылевоздушной смеси по ярусам горелок и снижения механического недожога топлива в топке за счет подачи в нижний ярус горелок пыли оптимальной для данного топлива крупности, а в верхний ярус горелок - пыли пониженной крупности. Для этого готовую пыль в сепараторе дополнительно разделяют на крупную и мелкую, аэросмесь с крупной пылью направляют на горелки нижнего яруса, с мелкой - на горелки верхнего яруса, расходы топлива по ярусам горелок регулируют изменением расходов аэросмеси. 1 ил.The method relates to the combustion of pulverized solid fuel and can be used in heat and power, industrial boilers and fire installations of other industries. An advantage of the invention is to reduce emissions of nitrogen oxides and mechanical underburning of fuel. This is achieved by controlling the flow of dust-air mixture over the burner tiers and reducing the mechanical underburning of fuel in the furnace due to the supply of dust of optimum size for a given fuel to the lower tier, and reduced-size dust in the upper tier of burners. To do this, the finished dust in the separator is further divided into coarse and fine, an air mixture with coarse dust is directed to the lower tier burners, and from small dust to the upper tier burners, the fuel consumption for the tiers of the burners is controlled by changing the mixture of the aero mix. 1 il.
