50t/h high-efficiency pulverized coal boiler project of Zibo Guangtong Chemical Co., Ltd.
Zibo Guangtong Chemical Co., Ltd. 50t/h high-efficiency pulverized coal boiler demonstration project boiler body and all its affiliated machinery and ancillary equipment process and construction drawing design, procurement, production, supply, installation and corresponding services, auxiliary building full construction drawing design.
A 50t/h high-efficiency pulverized coal boiler system and all its associated machinery and ancillary equipment, including:
A 50t/h-1.6MPa high-efficiency pulverized coal steam boiler body, pulverized coal storage and supply system, pulverized coal combustion system, flue gas treatment system, boiler steam water system, water treatment system, ash treatment system, electrical system (in boiler island) ), control system, etc.
The boiler furnace adopts the patented technology of Shanghai Jiaotong University, and a high-temperature combined vortex burn-out device is arranged in the combustion chamber of the pulverized coal boiler. The furnace is composed of a membrane type water wall made of a tube. The high-temperature combined vortex burn-out device is arranged at the upper outlet of the furnace, and is composed of a water-cooled wall pipe of the rear wall, and a water circulation system which is connected in parallel with the water-cooled wall of the front wall and the water-cooled wall of the side wall. The hot flue gas and unburned pulverized coal particles and volatile matter are fully mixed with the flue gas in the vortex burnout device, which prolongs the flue gas stroke, increases the residence time of the particles in the high temperature zone and reduces the q4 loss; In terms of the volatility, the volatiles are fully contacted with oxygen in the vortex burnout chamber, and are completely burned out in a high temperature environment to avoid the generation of black smoke, so that the q3 loss is zero.
