Delivery of the DZL series coal-fired steam boiler to Vietnam，this boiler is used in rubber factories
Hanyu Boiler’s 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.
The threaded smoke pipe is used to strengthen heat transfer, improve the heat transfer coefficient and thermal effi ciency, because the fl ue gas has a disturbing effect in the pipe. The smoke pipe is not easy to accumulate ash, and plays the role of self-cleaning.
