Corner Tube Coal Fired Boilers (bulk boilers)

? Boiler parameter range:
SHL20~100t/h;DHL29~70MW?
? Technical characteristics:
SHL series coal-fried field-assembled boiler adopted horizontal double drums,  with the flake type grate stoke and water cooling arch patent. It can be arranged  into single layer or two layers, with the characteristics of compact structure,  well sealing, light loading, fast temperature and pressure rising, enough  output and convenient installation.
DHL series corner tube boiler chooses the horizontal outside single drum and  without the steel structure, with the characteristics of compact structure,  leaving factory on modules, fast temperature rising, high heating efficiency,  high safety, low failure rate and long service life. This type of boiler is the  advanced energy-efficient one, which the country encourages to update.
