Threaded Smoke Pipe Chain Grate Biomass Steam Boiler Vertical 10t/H
has good heat transfer effect and the chain steam boiler runs stably
Product introduction:
The new DZL series steam boiler is a single cylinder-type longitudinal water-fire tube shell boiler, and the combustion equipment is a chain grate. The water cooling wall on the left and right sides of the furnace is a radiant heating surface, the convection heating surface in the upper two wings of the furnace is a convection heating surface, and the threaded smoke pipe (with a diameter of 57×3) is arranged in the boiler drum. The furnace wall adopts a new process of heat-resistant concrete cast and rammed as a whole, and the outer side of the boiler main engine is a 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 a quasi-steel body to a 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 lower part of the drum has a refractory layer, so that the high temperature area of the drum is not directly affected by the flame radiation heat, and the lower part of the boiler shell is prevented from bulging.
(3) The use of high efficiency heat transfer threaded smoke pipe, to obtain enhanced heat transfer effect, to achieve the boiler heating, pressure boost characteristics, improve the thermal efficiency of the boiler.
