High efficiency SZL coal fired boiler combustion part adopts double grate combustion chamber, temperature rise, and pressure rise fast, on the unburned gas after secondary combustion, play a full combustion, smoke elimination, and dust removal role. Coal steam boiler furnace top of horizontal pipe as the convection hot spots, assigned by the furnace bottom and furnace grate tube as radiation hot spots, furnace and the flue gas flow structure, rational layout, good heat transfer, the steam boiler design is reasonable, simple structure, convenient operation and maintenance, cover an area of an area small, less infrastructure investment, is the ideal equipment of small enterprises production use.
SZL type double drum longitudinal arrangement of chain grate pipe steam boiler, convection arrangement of heating surface heat exchange efficiency is high, water circulation system is reasonable, water capacity, steam space is large, steam quality is good. The convection heating surface has the largest affluence, the efficiency characteristics of the boiler operation is stable and has a certain overload operation capacity. The boiler automation level is high, the boiler feed water automatic regulation, high and low water level alarm, low water level chain protection, guide, fan chain protection. Boiler coal, slag and other operations are mechanized, complete supporting auxiliary machines.
Chain grate boiler is a typical front feeding fuel boiler. The grate moves slowly from front to back like belt conveyor. The fuel comes down from the coal scuttle onto the grate and moves along with it. Air comes in under the grate from the bottom up and intersects the fuel supply direction. When the fuel passes through the coal lock, it is scraped to a certain thickness and then enters the furnace. After the fuel is irradiated in the furnace, it enters the combustion stage.
Eco-friendly SZL coal fired boiler is suitable for textile, printing and dyeing, paper, food, rubber, plastic, chemical, medicine, steel, metallurgy and other industrial products processing process needed steam, and can be used for enterprises, agencies, hotels, schools, catering, service industries such as heating, bath, air conditioning and domestic hot water.
SZL series coal fired boilers employ key machining technologies such as sheet blanking, ring and tube plate drilling, all of which use advanced CNC machining to reduce assembly pressure and extend the service life of steam boilers. Advanced CNC technology is used for steel pipe cutting, threaded pipe pressing and convection pipe machining. The welding of longitudinal and circular joints of steam boilers, the welding of pipes and boiler barrels, the welding of pipes and flanges and other important parts are automatically submerged arc welding or gas shielded welding, etc., and automatic welding technology to ensure the quality of welding. ZOZEN strictly controls each process to ensure that each boiler product is of high quality and users can use it with confidence.
