DZL type horizontal chain biomass- fired steam boiler is a horizontal three - trip water - fire tube boiler.Two fire tubes are arranged in the pot barrel, and both sides of the furnace chamber are equipped with light tubes and water wall tubes.The combustion equipment adopts light chain grate to realize mechanical coal feeding, and is equipped with drum and induced draft fan to realize mechanical ventilation.The fuel falls on the grate from the coal sill, burns along with the grate, and the flue gas passes through the upper combustion chamber of the rear arch, enters the first bundle through the smoke chamber of the rear shed pipe to the front smoke box, folds into the second bundle from the front smoke box to the back smoke box, is introduced into the flue, dust collector and chimney through the induced draft fan, and finally exhausts to the atmosphere.The boiler automation level is high, the boiler feed water automatic regulation, high and low water level alarm, low water level interlock protection, lead, fan interlock protection.Boiler coal, slag and other operation mechanization, reduce the labor intensity of workers, complete supporting auxiliary machines.
Performance advantage
1, the use of efficient heat transfer components - threaded smoke pipe, with a reasonable flow rate of flue gas, boiler thermal efficiency than the national professional standards of 6-8 percentage points higher.
2. Arched tube plate and threaded smoke pipe make the pot shell change from quasi-rigid body to quasi-elastic body, and cooperate with airfoil flue, completely avoid the defect of cracking of high temperature tube plate of traditional firework tube boiler.
3. Reasonable water circulation loop and unique backwater ejector device (hot water boiler) can improve the water speed of rising pipe and avoid the pipe bursting of water-cooling wall.
4. Adopt the inertial separation of smoke and dust in the furnace, supplemented by efficient multi-pipe dust collector, so that the dust concentration of the boiler can meet the requirements of a class of areas.
5. Reasonable boiler structure can support its own weight without steel frame.
6, the use of energy saving, strong radiation furnace arch, can ensure the stable combustion of fuel.
7. Adopt high standard and high quality auxiliary machines, accessories and automatic control equipment to ensure the safe and stable operation of the boiler and reduce the labor intensity of the stoker.
8. Compact structure, 1-20T /h(0.7-14MW) boiler can be arranged in one layer.
Application scope:
The steam boiler is used for producing desired steam for product manufacturing process in the weave factory, printing and dyeing, papermaking and other industry like: food, rubber, plastic, chemical, pharmaceutical, etc, and for heating room and bath in factories, departments, hotels, schools, restaurants, services industries etc.
