1.single drum with three-stage central. 2.larger heating surface, better heat transfer. 3.low exhaust smoke temperature.
Product Features of DZL Chain Grate Coal-Fired Boiler
The horizontal drum of the three-stage central boiler is laid out in longitudinal arrangement.
Both sides of the furnace are covered densely with the bare tubes and water-wall tubes.
Inside the drum are two-stage thread flue tubes, and the flue gas flows through these
through three stages.
This quick-assembly boiler requires shorter period of erection and low installation costs.
