DZL series biomass steam boiler is a kind of horizontal three return water and fire tube boiler, the boiler drum is arranged in the high efficiency heat transfer threaded smoke pipe, can strengthen the heat transfer effect, improve the boiler thermal efficiency. High efficiency biomass boiler uses chain grate to ensure uniform feeding, convenient control and more stable incineration. Zozen Boilers optimized the design of this type of boiler, solved the problem of easy coking, improved the thermal efficiency obviously and saved the fuel cost.
This series of biomass fired boiler adopts the arch type tube plate and the threaded smoke pipe to form the cylinder, which makes the cylinder change from a quasi-rigid body to a quasi-elastic structure, cancels the pull support parts in the tube plate area, and reduces the stress. The smoke pipe in the tube plate is changed from two return to single return to solve the problem of crack in the tube plate. The lower part of the drum because of the placement of the rising pipe row, eliminate the bottom of the drum dead water area, so that the sludge is not easy to deposit, the high temperature area of the drum can be good cooling, prevent the bottom of the boiler bulge. Biomass steam boiler selection of high efficiency heat transfer threaded pipe, obtain the heat transfer effect, to achieve the characteristics of boiler temperature rise, fast pressure increase, improve the thermal efficiency of the boiler.
High efficiency biomass boiler are compact in structure and small in size, which can save the capital investment of boiler room. The boiler adopts screw pipe to strengthen heat transfer and improve the heat transfer coefficient and thermal efficiency. Because the smoke in the tube has a disturbance. Smoke pipe is not easy to accumulate ash, play a role in cleaning. The common double-layer secondary air design improves the ignition conditions of biomass fuel. Independent air chamber is selected to achieve reasonable air distribution, so that an aerodynamic field conducive to incineration is formed in the furnace, making the incineration temperature high and the incineration efficiency high.
Biomass fired steam boiler can choose scale type chain grate, mechanized feeding. Feeding uniform, burning stable, easy to operate, with not easy tempering, mechanical cleaning convenient characteristics. The ignition speed can be controlled by adjusting and controlling the secondary air volume. Can complete the imitation of controlled speed incineration, will not produce deflagration. The operation is stable, the adjustment is convenient, the effort is sufficient. Secondary air is arranged in front and rear arches to ensure secondary incineration of fly ash after particle differentiation with high incineration efficiency.
High efficiency biomass boiler eight-shaped wall in the furnace and the outlet chimney all have the function of dust removal, so that the original dust emission concentration of the boiler is controlled below the standard. In order to ensure that the boiler smoke emission to achieve environmental protection targets. Zozen Boilers has been dedicated to producing various types of industrial Boilers for many years, after continuous improvement, we have absorbed more advanced production experience, now our boiler products are exported to more than 100 countries and regions, boiler projects are all over the world, welcome to consult and purchase.
