A SELF-CLEANING, DUST-REMOVING, LOW NOX SOX, HIGH EFFICIENCY, FOUR-CHAMBER, THREE-CYCLE COAL-WATER SLURRY CONDENSING BOILER

摘要

The invention discloses a self-purification dedusting water-condensation-type four-chamber ternary-cycle water-coal-slurry boiler with low-NoxSOx and super efficiency, and in particular relates to a four-chamber-type structure which is provided with a dry heat hearth, and the hearth is provided with a water-coal-slurry combustor, a temperature-control sewage combustor, a heat convection hearth, an ash content centrifugal hearth, a water-condensation-type heat-absorption superconductive tube bundle hearth. The functions of configuration for water-coal-slurry combustion, sewage combustion simultaneously, low NOxSOx, super-purification and dedusting, condensation water recycling and residual heat recycling are realized for the boiler which saves energy by around 25% compared with the existing water-coal-slurry boiler; and the problems of coal combustion pollution of our country and even the whole world and the recycling and heat latent can not be realized by the restriction of 35-45% of water content by the existing water-coal-slurry technology are solved radically, and the realistic possibility of the first economy in life, industrial and power generation operation for the water-coal-slurry boiler is provided for the whole world.
