product introduction:
DZH biomass wood boiler is a new type of high efficiency and low carbon environmental protection boiler fueled by biomass wood, which is mainly divided into biomass steam, biomass thermal oil furnace and hot water boiler. The main fuel of biomass wood boiler includes wood, straw, rice straw, fuelwood, coconut shell, peanut shell, melon seed shell, corn cob, beet pulp bark and other waste combustible crops, which can be directly burned without additional processing. Coal combustion can also be used to achieve dual use. Its raw materials are widely distributed and the cost is low. Biomass wood boiler is known for its cheap coal and is an economical and affordable clean energy boiler. It is especially suitable for areas with high environmental protection requirements and biomass resources.
DZH type steam boiler is a single cylinder-type longitudinal water-fire tube shell boiler, and the combustion equipment is a movable grate. The water cooling wall on the left and right sides of the furnace is the radiant heating surface, the two wings of the furnace are the convection heating surface, the threaded smoke pipe is arranged in the boiler barrel, and the convection heating surface is made of refractory brick. The furnace wall is made of heat-resistant concrete casting and ramming. The outer side of the boiler main engine is the three-dimensional protective plate shell.
Product characteristics:
1. The cylinder is composed of arch tube plate and threaded smoke pipe, so that the cylinder is changed from quasi-steel body to quasi-elastic structure, and the pulling member in the tube plate area is cancelled, and the stress is reduced. The smoke pipe in the tube plate is changed from two return trips to one return trips, which solves the problem of tube plate cracks.
2. Due to the arrangement of the rising pipe row in the lower part of the drum, the dead water area at the bottom of the drum is eliminated, so that the mud is not easy to deposit, and the high temperature area of the drum can be cooled well to prevent the bulge in the lower part of the drum.
3. High efficiency heat transfer threaded smoke pipe is used to obtain enhanced heat transfer
