SZL Series Biomass-fired Steam(Hot Water) Boilers
The SZL series quick-assembly water-tube boiler is a double-drum water-tube chain grate boiler that burns medium-quality bituminous coal and biomass.
PRODUCT DETAILS
The boiler body consists of two longitudinally arranged drums, upper and lower, along the boiler's centerline. The front part of the upper drum, together with the water-cooled walls on both sides, forms the radiant heating surface of the furnace, while the rear part of the upper drum and the lower drum form a convective heating surface through a tube bundle. The combustion equipment uses a lightweight chain grate; it is shipped as a complete, quick-assembly unit. Electrical control enables stepless grate speed regulation, limit parameter alarms, and interlock protection. This type of boiler features: compact structure; easy installation and low infrastructure investment; mechanized feeding and ash removal; good water circulation characteristics; rapid temperature and pressure rise during startup; sufficient output and high efficiency. It is a popular heating equipment for steam production in small and medium-sized industrial and mining enterprises and for residential heating.
