1.Applicable fuel 

This product uses a fast furnace combustion method, which can burn wood chips, wood blocks, wood strips, bark, bamboo silk, clothing and luggage enterprise waste, and broken agricultural straws. 

2 Structural features 

(1) The arched tube sheet and the threaded smoke tube are used to form the drum, so that the drum is changed from a quasi-steel body to a quasi-elastomeric structure, and the bracing parts in the tube plate area are eliminated, and the stress is reduced. The smoke tube in the tube sheet is changed from two passes to a single pass, which solves the problem of tube sheet cracks.

(2) As the lower part of the drum is arranged with the rising pipe row, the dead water area at the bottom of the drum is eliminated, so that the sludge is not easy to deposit, and the high temperature area of the drum can be well cooled, preventing the bulge in the lower part of the drum. 

(3) The use of high-efficiency heat transfer threaded smoke tubes has achieved enhanced heat transfer effects, achieved the characteristics of boiler heating and pressure rise quickly, and improved the thermal efficiency of the boiler. 

(4) The structure is compact, and compared with the same type of boiler, the overall size is small, which saves the investment in the infrastructure of the boiler house. 

(5) Stable operation, convenient adjustment and sufficient output. 

(6) Threaded smoke tube is used to enhance heat transfer, which improves the heat transfer coefficient and thermal efficiency, because the flue gas has a disturbing effect in the tube. Dust is not easy to accumulate in the pipe, which plays a role of self-cleaning. 

(7) The eight-shaped wall in the furnace and the exit smoke window have a certain dust reduction effect. The original dust concentration of the boiler is controlled below the standard, which ensures that the smoke and dust emission of the boiler meets the national environmental protection regulations. 

(8) The unique double-layer secondary air design improves the ignition conditions of biomass fuels. The independent air chamber is adopted to achieve reasonable air distribution, and an aerodynamic field conducive to combustion is formed in the furnace, which makes the combustion temperature high and High combustion efficiency.
