DZL series horizontal biomass fired steam boiler adopts new water fire tube combination structure with single tube longitudinal. The boiler adopts three-return design, independent air chamber, integral or assembled type, compact structure and short installation cycle. Biomass pellet steam boiler covers a small area, fast temperature and pressure rise, simple operation, easy maintenance and high thermal efficiency. Convection tube bundle adopts threaded flue pipe, which makes flue gas spiral rotation, high heat transfer efficiency, and improves independent thermal efficiency and gas production. The boiler can burn biomass pellets, wine lees, rice bran, wood chips, straw and other fuels.
Biomass pellet steam boiler is set with front and rear arch-shaped tube plates to improve the flexibility of the tube plates, thus reducing the thermal stress at the welding end of the tubes and preventing the tube plates from cracking. Equipped with large volume furnace chamber and wing flue, it effectively reduces the local high temperature at the bottom of steam ladle and prevents bulging. This series steam boiler can effectively reduce the flue gas emission concentration and exhaust temperature, with higher front arch and lower rear arch, rapid ignition, large combustion area, high ash combustion rate, and improved boiler thermal efficiency.
The DZL biomass fired boiler adopts high quality heat transfer elements and makes use of the strong self-purification ability of the spiral flue tube, and the gas flow rate of the spiral flue tube can still be above 8m/s at half load. This series of boiler products can produce self-dusting capability above this flow rate (the rotating high-speed airflow will collect and sweep away the ash below the half-load), and this ash collection phenomenon makes this type of boiler in constant output and efficiency in year-round operation. The heat transfer elements of biomass pellet steam boilers are optimized for suitable flow resistance, no ash accumulation, low wear and tear, high strength and fatigue resistance.
This series boiler includes three air chambers in front, middle and back, chain or reciprocating grate, and the combined arch formed by the front supply and back use. At the bottom of the chamber is arranged in the middle air chamber and realize segmented with air, the front and rear air chambers are each arranged with a grate, the upward inclined arch channel is installed above the front of the furnace, and the inclined arch is installed at the back of the furnace. This combination of boiler and combustion characteristics of biomass fuel makes the adaptation to a wide range of biomass types, good combustion degree of the boiler and bottom effect of pollution emission.
Biomass pellet steam boiler is widely used in various industrial industries, such as textile, chemical, paper making, machinery, food, agricultural products processing industry, etc. This new type of high quality insulation material is light in weight, low heat loss and has superior heat preservation performance.ZOZEN Boiler specializes in producing all kinds of boiler products and has established friendly cooperation with customers from more than 100 countries and regions. The boiler products are of good quality and stable operation, welcome to consult!
