Product Description
DHL series coal burning bulk boiler adopts double boiler barrel horizontal arrangement, scale type grate, membrane type water cooling wall structure, water cooling arch patented technology, it can be arranged in single or double layers flexibly, with compact structure, good sealing, light load, fast heating and boosting, sufficient output, easy installation and other characteristics. DHL series corner tube boiler series, single cross tube chain grate tube boiler, boiler barrel for external type, no steel frame structure, with a compact structure, modules out of the factory, fast heating, high thermal efficiency, good safety, low failure rate and long service life and other advantages. High efficiency and energy saving boilers that encourage upgrading of technology.
Technical Advantages
Beam Grate
Adopt the cross – beam grate, the grate running resistance is small;The grate cooling effect is good and the failure rate is low.Small amount of fuel leakage in grate.
Light Furnace Wall Structure
Good insulation performance, no leakage of ash, good environment.At the same time, the boiler adopts the design idea of secondary turbulent combustion and the technology of high-temperature separation of fly ash and internal circulation fluidization and reburning of fly ash.
Range of Application
Thermal power plants, shipyards, petrochemical medicine, biological engineering, food and so on.
