Quanzhou Minquan Boiler Co., Ltd. relies on its own advantages in the boiler research and development, combined with advanced European machine-building technology, independent development of the Quartet's new energy-efficient environmentally friendly pulverized coal boiler system, the system implementation of the whole process closed operation management, centralized control automation, The boiler automation operation and management is realized, which ensures the efficient and stable operation of the pulverized coal boiler system.
A series of dozens of boilers with three series of high efficiency pulverized coal boilers and their derivative products have been widely used in many fields. The new high-efficiency pulverized coal boiler system consists of: pulverizing system, storage system, combustion system, measurement and control system, safety system, boiler system, and flue gas treatment system. Pulverizing raw materials into the milling system, according to coal conditions and combustion requirements to meet the requirements of pulverized coal processing, closed tanker will be in line with the standard pulverized coal injection tower, pulverized coal tower into the coal bunker on demand, falling The feed tube is then fed by a feed valve, feeder, etc. into the burner. Burner built-in pre-combustion chamber to improve the pulverized coal temperature and enhance the mixing of pulverized coal and air, the burn rate of coal to achieve more than 98%, the burner can be equipped with a variety of furnaces and arrangements, the whole no coke, No deflagration, high safety factor, graded air distribution and flue gas recirculation technology make the initial emission concentration of NOx only 300mg/m3. Purification system can remove flue gas entrained in the solid particles, sulfur dioxide, nitrogen oxides and other harmful substances, meet national or regional emission standards, the ash discharged through a closed system, focused on the collection and use. Monitoring system and safety system adopt modern automatic control technology to realize automatic and intelligent control throughout the process of milling, storage, transportation, combustion, purification, ash discharge and safety of boilers. That is to say, the system is efficient and the thermal efficiency of the boiler reaches as high as 90% Above, energy saving is more than 30% compared with traditional boilers, and land and investment are saved more, and costs can be recovered in a relatively short period of time.
