The new DZH series boiler for single cylinder vertically type water fire tube shell boiler, grate furnace equipment for activities on both sides of the water wall for radiant heating surface combustion furnace, two convection heating surface, the drum arranged within the thread smoke tube convection heating surface, and the whole arch with heat-resistant concrete pouring tamping new process molding, host boiler lateral to the three-dimensional shape of plate shell.
Our DZH series boiler using the latest scientific research, such as: the arched tube plate and the thread smoke tube, hot water boiler water injection technology, solves the crack of tube plate shell type boiler, drum drum bag, the lower water wall tube, the thermal efficiency is low, low output, poor adaptability of coal the problem.
1, safe and reliable operation, simple and convenient operation, material selection boiler plate, boiler tubes, and materials into the factory after re examination, qualified before use, so long service life. The boiler adopts a single cylinder and arched tube plate structure, and the whole structure is simplified as a quasi elastic structure to improve the safety factor.
2, wide adaptability to coal, black smoke and dust using advanced adiabatic combustion technology, layout low and long before the arch, accelerate the ignition, combustion, high volatile in front of the high temperature of boiler flue gas is forced through the main combustion zone, full combustion, to achieve the purpose of eliminating smoke and dust.
2. Performance characteristics of horizontal fast coal fired steam boiler:
1, DZH series boiler: consists of two large parts assembly factory, by the large upper furnace body, furnace wall and a heat insulating layer; the lower parts by the movable grate and the door, on the assembly structure, saving boiler room area, reduce installation cost and infrastructure investment;
2, the arch tube plate and the thread smoke pipe are used to form a boiler barrel, so that the cylinder can be changed from a quasi steel body into a quasi elastic structure, and the bracing component in the tube plate region is cancelled, thus reducing the stress. The smoke pipe is changed from two backhaul to single return stroke, and the problem of pipe plate crack is solved.
