SZL type assembled biomass boiler

★ National patented products: ★ Major technological breakthroughs in product design: ★ Domestic technological leadership level: This type of boiler uses biomass pellet fuel, biomass bulk material, or bituminous coal as fuel. When burning biomass bulk materials, a new SZL bulk assembled biomass boiler should be used, and the grate should be a chain grate or a reciprocating grate according to the fuel. The special design is as follows: 1. The boiler furnace is designed as a fully water-cooled combustion chamber. The left and right membrane walls extend all the way to the upper surface of the grate, forming a water-cooled furnace with front and rear water-cooled arches, increasing the radiation heating surface of the furnace and improving the boiler output and thermal efficiency. 2. Innovative arch structure design. The pipe is led out from the bottom of the lower drum to form a rear arch pipe on both sides of the manifold, successfully solving the technical problem of increasing the height of the boiler when arranging water-cooled arches, resulting in idle and wasteful boiler space. 3. The boiler adopts a low thermal inertia design as a whole. Due to the advanced water-cooled enclosed combustion chamber and clever rear arch structure, the boiler is more compact as a whole, and the radiation heating area of the furnace is increased by more than 50%; At the same time, the use of lightweight furnace walls reduces the thermal inertia of the boiler by 70%, which not only increases the boiler output and combustion efficiency, but also makes the boiler load adjustment more flexible. 4. The boiler body adopts a membrane water-cooled wall fully sealed structure. The sealing of the boiler ensures no air leakage, reduces heat loss and exhaust heat loss, improves the thermal efficiency of the boiler, and improves the working environment of the boiler room. 5. The boiler grate adopts a contact type lower sealing structure. The left and right collection boxes of the boiler were designed as anti coking collection boxes, and the side sealing iron was eliminated, completely solving the defects of side sealing sticking to the grate and uneven combustion air distribution caused by air leakage.
