The 4000kg  package coal-fired boiler is arranged with water-cooled walls on both sides to form the furnace chamber and convection flue, a single-return threaded flue pipe in the pot, and a cast-iron coal economizer at the end. The furnace chamber is equipped with water-cooled cast front and rear arches. The front arch is stepped and the rear arch is herringbone, so that the coverage of the arch is close to 85%, which is conducive to the combustion of bituminous coal. Large block type chain grate is used to realize mechanical combustion. It is equipped with a blower and induced draft fan for mechanical ventilation, and a slag dispenser to realize mechanical slag discharge, with complete control and monitoring instruments.

Coal-fired boilers are very popular in coal-rich areas, and the overall operating cost of coal-fired boilers should be lower than that of other fuel boilers. The modern ferrochrome smelter in Zimbabwe needs industrial boilers to provide a stable heat source for the metal smelting process. Through multi-channel research, the purchasing manager of this smelter finally selected ZOZEN Boiler as the coal fired boiler supplier for the Zimbabwe smelter.

ZOZEN Boiler DZL series coal-fired steam boiler structure adopts a unique water and fire tube three-return design, which fundamentally solves the problem of tube plate cracking in pure fire tube boilers and ensures the safety and stability of boiler operation. At the same time, the boiler fire tube uses high-efficiency heat transfer element threaded flue tube, the heat transfer coefficient is 1.8 times higher than that of ordinary flue tube, which effectively strengthens the heat transfer effect and makes the thermal efficiency of the boiler as high as 82% or more.
