(1) Adopting arch-shaped tube plate and threaded pipe to form the pot, making the pot from a quasi-steel body to a quasi-elastic body structure, eliminating the tube plate area of the pulling and bracing parts, reducing the stress. The flue pipe in the tube plate is changed from two returns to a single return, which solves the problem of cracking in the tube plate.
(2) Due to the arrangement of the rising pipe row in the lower part of the cylinder, the dead water area in the bottom of the cylinder is eliminated, so that the mud is not easy to be deposited, and the high temperature area of the cylinder can be well cooled, thus preventing the bulging of the lower part of the cylinder.
(3) Adoption of high-efficiency heat-transfer threaded flue pipe obtains enhanced heat-transferring effect, which achieves the boiler's characteristics of rapid temperature and pressure rise and improves the boiler's thermal efficiency.
(4) Compact structure, compared with the same type of boiler, small external dimensions, saving boiler room infrastructure investment.
(5) Stable operation, easy adjustment, sufficient output.
(6) The use of threaded pipe to enhance heat transfer, improve the heat transfer coefficient and thermal efficiency, due to the flue gas in the tube has a disturbing effect. As the flue gas has a disturbing effect in the pipe, it is not easy to accumulate ash in the pipe, which plays the role of self-cleaning.
(7) The eight walls in the furnace, the exit smoke window part have a certain effect of dust reduction. So that the original concentration of dust emissions from the boiler is controlled below the standard, ensuring that the boiler dust emissions to meet the targets set by the national environmental protection regulations.
(8) The unique double-layer secondary air design improves the biomass fuel ignition conditions, adopts an independent air chamber, achieves a reasonable air distribution, and forms an aerodynamic field favorable for combustion in the furnace chamber, which makes the combustion temperature high and the combustion efficiency high.
