Claims (6)

1. Способ сжигания угля, содержащего менее 10% летучих компонентов, в горелке при помощи дутьевого воздуха, при котором уголь размалывают в мельнице и подводят в горелку с применением воздуха в качестве газа-носителя в виде смеси угольной пыли и газа-носителя, отличающийся тем, что перед поступлением в горелку угольную пыль отделяют из смеси угольной пыли и газа-носителя, отделенную угольную пыль смешивают с подогретым воздухом и переносят в смесь угольной пыли и газа-носителя с повышенной температурой и меньшей долей углеродной пыли, а затем углеродную пыль снова отделяют из этой смеси и смешивают с нагретым воздухом и переносят в смесь угольной пыли и газа-носителя с повышенной температурой и повышенной долей угольной пыли.1. A method of burning coal containing less than 10% volatile components in a burner using blast air, in which the coal is ground in a mill and fed to the burner using air as a carrier gas in the form of a mixture of coal dust and carrier gas, characterized in that before entering the burner, coal dust is separated from the mixture of coal dust and carrier gas, the separated coal dust is mixed with heated air and transferred to the mixture of coal dust and carrier gas with an elevated temperature and a lower proportion of carbon dust, and then m carbon dust is again separated from this mixture and mixed with heated air and transferred to a mixture of coal dust and carrier gas with an elevated temperature and an increased proportion of coal dust. 2. Способ по п. 1, отличающийся тем, что угольную пыль из мельницы подводят в горелку в полупрямом режиме и первое отделение угольной пыли производят в сепараторе, установленном после мельницы. 2. The method according to p. 1, characterized in that the coal dust from the mill is fed into the burner in semi-direct mode and the first separation of coal dust is produced in a separator installed after the mill. 3. Способ по п. 1, отличающийся тем, что угольную пыль из мельницы подводят в горелку в косвенном режиме и первое отделение угольной пыли производят в пылевом бункере, расположенном перед вторым сепаратором. 3. The method according to p. 1, characterized in that the coal dust from the mill is fed into the burner in an indirect mode and the first separation of coal dust is produced in a dust bin located in front of the second separator. 4. Способ по одному из пп. 1-3, отличающийся тем, что подогретый воздух нагревают примерно до 400°С. 4. The method according to one of paragraphs. 1-3, characterized in that the heated air is heated to about 400 ° C. 5. Способ по одному из пп. 1-4, отличающийся тем, что долю угольной пыли в смеси с соответствующим количеством подогретого воздуха после первого отделения регулируют на уровне менее 0,5, предпочтительно менее 0,2 кг угольной пыли на 1 кг воздуха, а после второго отделения на уровне свыше 1,0 кг угольной пыли на 1 кг воздуха. 5. The method according to one of paragraphs. 1-4, characterized in that the proportion of coal dust in the mixture with the appropriate amount of heated air after the first separation is regulated at a level of less than 0.5, preferably less than 0.2 kg of coal dust per 1 kg of air, and after the second separation at a level of more than 1 , 0 kg of coal dust per 1 kg of air. 6. Способ по одному из пп. 1-4, отличающийся тем, что смесь угольной пыли и газа-носителя нагревают до 360-400°С. 6. The method according to one of paragraphs. 1-4, characterized in that the mixture of coal dust and carrier gas is heated to 360-400 ° C.
