SZL series biomass steam boiler is a double boiler tube vertical pipe chain grate boiler or reciprocating grate boiler with large heating area. The capacity of full load adjustment is strong. Biomass steam boiler steel furnace belly volume, with a better soot settlement function, convection tube bundle using S “type structure, good heat transfer effect, high thermal efficiency, dust removal effect, convenient ash. It can burn coal and biomass fuel with high ash content, which can be fully ignited and completely burned out.
The boiler has large capacity, complete internal devices and good steam quality. It is the product of boiler type selection for small and medium-sized steam units.SZL series biomass steam boiler design structure is reasonable, high thermal efficiency, fuel saving. Adopt the new technology of heat transfer thread pipe and arch pipe plate to improve the flow rate of flue gas, which makes the boiler reliable, energy saving and high thermal efficiency.
The optimized furnace arch has the advantages of strong radiation, stable combustion, good effect and fast heating. Well-made water cooling wall, effective protection of furnace wall. Advanced performance and long service life. All main welds adopt automatic welding, no repair record, to ensure the welding quality and improve the service life of the boiler. The pipe plate adopts advanced pressing technology to avoid the problem of pipe plate cracking.
This series of steam boiler fuel from coal scuttle land on fire grate, after entering the chamber of a stove or furnace burning, burning flame and high temperature flue gas, after the upper arch to combustion chamber into the state after return convection tube bundle, and then through the second and third convection bank process, by a third convection bundle exports of low temperature smoke gas, through the economizer, smoke by induced draft fan to the chimney into the atmosphere.
SZL series steam boiler combustion equipment adopts light chain grate, speed regulation adopts frequency conversion speed regulation, easy adjustment, stable operation, also can adopt reciprocating grate, better adapt to inferior fuel. Adopt the internal smoke and dust inertia separation, supplemented by multi – pipe dust remover or bag dust removal equipment. Automatic electric control system with complete monitoring instruments can realize automatic water replenishment,overpressure and overtemperature alarm, advanced remote control function, on-line monitoring of dosage, fault alarm and other functions.
