Horizontal chain biomass steam boiler
Author: Date: 2018-11-01

Product Details:

DZL quick-installed chain grate biomass boiler is a horizontal three-pass water-fire tube boiler. Threaded flue pipes are arranged in the drum. Water-cooled wall tubes are installed on the left and right sides of the furnace. The scale-type chain grate is more conducive to the combustion of biomass fuel. It is equipped with blowers and induced draft fans for mechanical ventilation, and equipped with a slag discharger to achieve automatic slag discharge.  
The fuel falls from the upper coal hopper to the grate and enters the furnace for combustion. The flame passes through the rear arch refraction and passes through the embossing chamber on both sides of the body to fold to the front smoke box. In the pipe, it enters the economizer through the rear smoke box, and is then drawn by the induced draft fan through the flue to the chimney and discharged into the atmosphere.

Performance advantages:
1. By pulling part of the ascending pipes on the headers on both sides toward the protection chamber, and then introducing the bottom of the drum side and supplementing the bottom of the drum with thermal insulation and casting to form the heating surface of the furnace roof, the pan was successfully solved with a novel furnace structure The bottom of the tube is directly radiated by high-temperature flames to avoid "bulging" defects;  
2. The setting of the two-wing flues allows the flue gas to enter the front smoke box smoothly, so that the temperature of the previous tube sheet is the same, and the tube sheet crack due to temperature stress is avoided;  
3. A single-return threaded tobacco pipe is used in the drum to enhance the heat transfer effect. At the same time, the threaded tobacco pipe has a self-cleaning function to avoid ash accumulation in the tobacco pipe;  
4. The front and rear arches of the boiler adopt the integral casting structure supported by water-cooled wall tubes to form a permanent arch. The rear arch is low and long, the exit section is anti-inclined, and the front arch inclination angle of 45 ° echoes the rear arch, forming a clear inverted "α" flame, which is conducive to the combustion of inferior coal and has strong adaptability to coal types;  
5. The grate side seal structure design is advanced and reasonable, which avoids the defects that the side seal card grate and the uneven air distribution on both sides of the grate burn out the side seal. 4t / h and below boilers use side-sealed cold-added angle iron rib plate structure, and above 6t / h boilers use contact side-sealed lower seal structure;  
6. There is an independent adjusting air chamber below the grate, and the air is introduced on both sides; the new crank arm screw adjusting structure is adopted, so that the cross-section ratio of air conditioning and ventilation can reach 100%, the adjustment is flexible, and the air is evenly distributed. Push-pull type ash cleaning device. The ram is made of heat-resistant cast iron with a sealed structure to prevent secondary combustion deformation and grate leakage.
