DZL series biomass-fired hot water boiler

DZL series package boilers are horizontal three-pass water & fire tube boilers with a chain grate stoker structure. Threaded pyrotechnic tubes are arranged in the drum to form a convection heating surface, while the drum and the water walls on both sides form a radiation heating surface in the furnace. Each package system is fully installed and wired before being transported to site and is electrically controlled to provide functions such as stepless speed regulation for the stoker, threshold parameter alert and interlock protection.

Product thermal capacity: 1.4 - 14 MW

Working pressure: 1.0-1.6 MPA

Available fuel: Biomass molding granules, wood chip, corn cob, palm shell

Our boiler products are applied in these enterprises.

Product Advantages


Lower NOx emission than the same products

Reasonably arranges the primary air and secondary air; adds economizer, dust collector and other devices at the boiler end; NOx emission is as low as 200mg/m3

Reliable and stable boiler operation for a long time

Selects suitable grate bar materials with high temperature resistance to improve the grate reliability and ensure the safe boiler production
