Specialize in manufacturing DZH coal boiler and industrial biomass central heating system for pharmaceutical industry
Features
1. DZH boiler structure design is conducive to fuel combustion. The DZH chain grate coal-fired (biomass) boiler arch adopts the latest design, and the outlet position is designed as a sloping structure. The anteversion angle corresponds to the backward inclination angle, forming an inverted “α” flame, which is conducive to fuel combustion and fuel type adaptability.
2. Avoid bulging defects. The riser of the header on both sides of the boiler is pulled toward the furnace, and the bottom of the drum covered with the heat-insulating material forms the heating surface of the top of the furnace. The novel furnace structure successfully solves the problem of direct high-temperature flame radiation at the bottom of the drum, avoiding the bottom of the boiler. The defect of the drum kit.
3. Special design to effectively prevent grate leakage. The steam boiler is designed with a push-pull gate ash cleaning device, and the ram is made of a heat-resistant cast iron finishing sealing structure, thereby effectively preventing secondary combustion deformation and grate leakage.
4. Avoid cracks. The flue is designed on both sides of the boiler body. This structure not only allows the flue gas to smoothly enter the front smoke box, but also effectively reduces the temperature of the pipe, and minimizes the crack of the body caused by the high temperature of the boiler.
5.The water circulation is simple, the structure of the pressure-bearing parts is reasonable, and it can be safely operated under the condition of ensuring water quality. At the same time, high-standard, high-quality auxiliary machines, accessories and automatic control equipment are used to ensure safe and stable operation of the boiler.
6. Water supply automatic control system. Automatic control of water supply. The water pump is started and the water supply system works normally. The water level difference sensor detects the water level signal and keeps the water level of the drum stable, thus maintaining normal steam generation. At the same time, the water level adjustment meter can clearly display the boiler water level.
