Biomass fired boiler is mainly composed of upper and lower drum, convection tube bundle, water wall tube, down tube and collection box. Upper and lower drum is longitudinal arranged. Combustion equipment uses chain belt type chain grate and is driven by stepless variable speed device. The boiler body is composed of a longitudinal upper and lower drum and a convection tube bundle. Biomass steam boiler technology advanced, absorption of excellent production experience, excellent research and development technology professional.
The boiler combustion chamber is surrounded by water-cooled walls, and the front and rear arches are made of water-cooled walls as the frame castable refractory castables. The service life of the furnace arches is longer. The left and right sides of the body are all membrane type water wall structure, the boiler has good tightness, small heat dissipation loss, and ensures the safe operation of the boiler. The new biomass boiler is a single cylinder longitudinal type boiler with water and fire tube shell. Its combustion equipment for the chain grate, the left and right sides of the furnace wall for radiation heating surface, the two wings of the furnace for convection heating surface. The convective heating surface of threaded smoke pipe is arranged in the drum.
According to the characteristics of biomass fuel, a unique combustion chamber and secondary air supply are set up to enhance the combustion. Biomass steam boiler technology advanced, front and rear arch using heat resistant concrete pouring ramming made of new technology. This series steam boiler adopts the latest scientific research achievements, such as: arch tube plate, threaded smoke pipe, figure eight row pipe and so on. Effectly solve the boiler tube plate crack, the lower part of the drum bulge, water wall burst pipe, low thermal efficiency, insufficient output, poor fuel adaptability and other problems.
Biomass fired steam boiler has the advantages of high thermal efficiency, large furnace space, low operating cost, clean and environmental protection. At present, the number of users using biomass boilers is gradually increasing, and it has gradually become one of the mainstream products of boilers. In the design of the boiler, the high efficiency and energy saving strengthened combustion technology is adopted to ensure the full combustion of the fuel. Even better, the volume of the furnace and embers chamber is very large, which is conducive to the embers and settlement of fly ash. The steering-chamber with coarse separation of dust at the outlet fume window achieves the purpose of dust removal in the boiler furnace, reduces the emission of flue gas, and makes it reach the target of environmental protection regulations.
Biomass steam boiler technology advanced, professional production, the use of threaded pipe heat transfer, improve the thermal efficiency, reduce energy consumption. The application of membrane water-wall structure can improve the heat transfer coefficient and effect, and reduce the heat loss. Threaded smoke pipe is arranged in the pot shell, the overall air leakage is less, the heat loss of smoke exhaust is small. The welding seam of boiler adopts advanced submerged arc automatic welding technology to ensure the welding quality. The dust collector is arranged in the tail flue to ensure that the smoke discharge meets the requirements of environmental protection.
