CAMERA combustion in coal power plants, METHOD OF SERVICE OF THIS CAMERA AND METHOD FOR OPERATING THE COAL POWER PLANT

摘要

1. A combustion chamber in a power plant, a coal-fired, comprising: - a combustion chamber housing defining a combustion zone in which is combusted coal dust, - at least one burner which introduces the pulverized coal into the combustion zone, - channel overfire air, which blows air into the combustion chamber housing above the combustion zone, wherein the overfire air channel generally stationary relative to the housing of the combustion chamber; u nozzle conjugated with overfire air duct, wherein the nozzle comprises a flow guide device, located inside the channel and capable of overfire tilted with respect to the channel overfire air to cause a change in direction of the air flow injected into the combustor body through the channel of acute dutya.2 . Combustion chamber according to Claim. 1, wherein overfire air channel comprises an air inlet device which injects air into the combustion chamber housing, wherein the air inlet device has a cross-section round or oval formy.3. Combustion chamber according to Claim. 1, in which the flow direction of the device comprises a frame carrying a plurality lopastey.4. . The combustion chamber of claim 1, wherein the nozzle further comprises: - a hinge device for tilting the device in the channel flow direction overfire air; u handling device interfaced to sharnirnymustroystvom, wherein the handling device is controlled from outside the combustion chamber housing to cause the tilt direction potoka.5 device. Combustion chamber according to claim. 4 in which the handling device can be selectively pushed to the casing of the combustion chamber and to delay the combustion chamber housing to cause the inclination of the device flow direction
