Abstract
The utility model discloses a novel pulverized-coal fired boiler system, which comprises a pulverized coal bin, a pulverized-coal fired boiler, a bag-type dust collector and a fume extractor, wherein the pulverized coal bin is connected onto the combustor of the pulverized-coal fired boiler through an air and pulverized coal mixing pipeline; the other end of the pulverized-coal fired boiler is connected onto the bag-type dust collector; the bag-type dust collector is connected onto one end of the fume extractor through a draught fan. A pulverized coal receiving and storing unit, a pulverized coal conveying unit, a pulverized coal combustion and ignition unit, a boiler heat exchange unit, a fume purification unit, a fume discharge unit, a pulverized coal ash discharge unit and the like are combined by the novel pulverized-coal fired boiler system, and thereby, the combustion efficiency and the thermal efficiency of the system are improved, and the fume discharge value is reduced by the comprehensive installation of the bag-type dust collector, the draught fan and the fume extractor, thus, a pollutant emission reduction effect is achieved.
Description
Technical field
The utility model relates to a kind of pulverized-coal fired boiler.
Background technology
At present, the whole nation is having more than 50 ten thousand with Industrial Boiler, about 1,800,000 steaming tons/hour.Wherein, about 480,000 of coal-burning boiler accounts for about 85% of Industrial Boiler total capacity, annual about 400,000,000 tons of the raw coal that consumes.China's coal-burned industrial boiler average operating efficiency only is 60%～65%, and its discharging flue dust has seriously influenced production environment.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of new coal powder steam generator system that can reach efficient operation and clean emission is provided.
The new coal powder steam generator system that the utility model provides comprises Pulverized Coal Bin, pulverized-coal fired boiler, sack cleaner and fume extractor, described Pulverized Coal Bin is connected on the burner of pulverized-coal fired boiler by wind powder mixing duct, the pulverized-coal fired boiler other end is connected on the sack cleaner, and described sack cleaner is connected fume extractor one end by air-introduced machine.
The utility model combines unit such as coal dust acceptance and deposit, coal dust conveying, coal dust firing and igniting, boiler heat exchange, gas cleaning, fume emission, flyash discharging, efficiency of combustion and system thermal efficiency have been improved, comprehensively being provided with of sack cleaner, air-introduced machine and fume extractor reduced smoke discharge amount, reached the effect of pollution reduction.
