biomass pellet wood fired thermal oil boiler, ZOZEN DZL series tri-drum biomass-fired boiler comes into being

ZOZEN Boiler (Wuxi) is a designated manufacturer of boilers and pressure vessels approved by the General Administration of Quality Supervision, Inspection and Quarantine of the People’s Republic of China. ZOZEN holds the A-grade boiler and BRⅡ-grade pressure vessel manufacture licenses, ASME “S” and “U” certificates with steel seals and fully passes the ISO9001:2000 international quality system certification.

On November 14, a large-scale environmental protection inspection of coal-fired boilers was carried out locally in Afghanistan, and a large number of factories that did not meet environmental protection standards were closed. At the same time, the SZL series of coal-fired boiler customized by ZOZEN Boiler for Baheer Group passed the environmental protection inspection because of its sufficient output, high combustion efficiency and ultra-clean flue gas emission.

ZOZEN SZL series chain grate boilers have high combustion efficiency, strong overload capacity, wide coal type adaptability. The boiler is mainly composed of upper and lower drums, convection tube bundles, water-cooled wall tubes, downcomers and headers. The upper and lower drums are longitudinal arranged. The combustion equipment adopts the chain grate with chain belt and is driven by a stepless speed change device.

biomass pellet wood fired thermal oil boiler, The grate bracket of ZOZEN’s chain grate boilers adopts double-layer structure. The lower layer uses channel steel and the upper layer uses light rail. The upper layer is heated and the lower layer is stressed. It changes the traditional grate bracket using angle steel and friction strips without  deformation. The active grate runs on the light rail with a 72-hour cold test run carried out before leaving the factory to ensure the smooth operation of grate without deviation or jamming.

ZOZEN Boiler has set up seven process stop points that are material re-inspection, material inspection number transfer, plate welding test, heat treatment, pre-expansion before welding, flaw detection inspection, hydrostatic test, which are inspected by seven responsible engineers. If any link is unqualified, it will not be able to proceed to the next process, which ensures that each ZOZEN boiler has the high quality.

biomass pellet wood fired thermal oil boiler, In the field of industrial boiler manufacturing, ZOZEN natural gas fired boiler, with years of technological accumulation, advanced manufacturing technology and outstanding performance advantages, is outstanding among similar products and has become the common choice of all walks of life. This time, ZOZEN Boiler and Dalishen Technology Group reached the cooperation to seek the common development.

In the future, ZOZEN will continue to play its own Advantages in the field of industrial boiler manufacturing and provide high-quality boiler products for more enterprises to lay a solid foundation for development, biomass pellet wood fired thermal oil boiler.
