Structure introduction:
The new DZH series hot water boiler is a single cylinder-vertical type 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 convection heating surface is arranged in the boiler drum, the furnace wall is made of heat-resistant concrete cast and rammed as a whole, and the outer side of the boiler main engine is the three-dimensional protection plate shell. The overall structure of the boiler body adopts the form of an upper boiler drum, a water wall tube and a collecting box arranged symmetrically. The barrel is formed by welding the barrel body and the front and rear tubesheet. The furnace of the boiler is arranged with a spark-retaining wall, and the combustion efficiency is high. This series of boilers use the latest scientific research results, such as: header return water ejection, arch tube plate, threaded smoke pipe, etc., to solve the boiler shell tube plate cracks, water wall explosion, low thermal efficiency, insufficient output, poor coal quality adaptability and other problems.
Performance advantage:
(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 riser 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) 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.
(4) Compact structure, compared with the same type of boiler, small size, saving boiler room infrastructure investment.
(5) Stable operation, convenient adjustment, sufficient output.
