product presentation:
The DZL type chain grate boiler is a horizontal three-return water-fire tube mixed boiler, in which a bunch of threaded smoke pipe is arranged in the barrel. The left and right sides of the furnace are equipped with light tube water cooling walls. The light chain grate is used to realize mechanical coal feeding, equipped with blower and induced draft fan for mechanical ventilation, and equipped with scraper slagging machine for automatic slagging. The front and rear arches of the furnace adopt a new energy-saving technology. The fuel falls from the coal hopper to the grate, enters the furnace and burns, and the flame passes through the rear arch refraction to turn upward through the burning chamber on both sides of the body to the front smoke box, then returns to the inner tube bundle of the pot from the front smoke box, enters the economizer through the rear smoke box, and then exhausts to the atmosphere by the induced fan through the flue to the chimney.
structural 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 rising pipe rows in the lower part of the cylinder, the dead water area at the bottom of the cylinder is eliminated, so that mud is not easy to deposit, and the high temperature area of the cylinder can be cooled well, preventing the lower part of the cylinder 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.
4. Compact structure, compared with the same type of boiler, small size, saving boiler room infrastructure investment.
5. Stable operation, convenient adjustment, sufficient output
6. The threaded smoke pipe is used to strengthen heat transfer, improve the heat transfer coefficient and thermal efficiency, because the smoke has a disturbance in the pipe, the smoke pipe is not easy to accumulate ash, and plays the role of self-cleaning.
7. The splayed wall in the furnace and the exit smoke window have a definite dust removal effect. The original dust concentration of the boiler is controlled below the standard to ensure that the boiler dust emission reaches the national environmental protection regulations.
