The rubber tires produced by the factory have superior air tightness, excellent heat resistance, aging resistance, and adapt to the use of high-speed cars. They are specialized in the production of butyl rubber meridional tube, with annual production capacity of 2 million pieces of high-quality butyl rubber meridional tube. At present, most of the steam boiler used in tire factories evaporation is generally between 4 to 35 t, steam in the tire production of power costs accounted for a higher proportion. For the capacity of the factory, ZOZEN’S recommended a SZL quick-loading coal-fired steam boiler of 6 tons. 6 tons SZL steam boiler in the factory is fully assembled factory, the front end of the boiler body is arranged around the water wall. Top connected with drum, bottom boiler and the header connection, form the combustion chamber, the absorption chamber of a stove or furnace radiant heat, backend arrangement between water drum on intensive convection tube bundle, high temperature flue gas after combustion scouring by secondary return transverse convection heat surface, then to separate arrangement of economizer, finally into the dust discharge, the rational allocation of burning full, extensive application of coal.
Customer feedback: “Zozen Boilers has a compact structure, a single-story boiler room layout, reasonable floor space, convenient and fast on-site installation, and ZOZEN’S provides high-efficiency steam for our tire production at the lowest cost.” SZL type steam boiler furnace and combustion chamber The side adopts membrane type water wall structure. The membrane water wall structure is independently designed by our company. The membrane water wall structure used for power station boilers is applied to the assembled boiler. Its advantages are large heat transfer coefficient, good conduction effect, low heat loss, good air tightness, and furnace wall No deformation, no dust leakage.
The front and rear water wall pipes of the 6 tons SZL steam boiler furnace extend downward to the upper part of the grate to form front and rear arches. This structure is added on the basis of the original mature bulk boiler, and the radiant heating surface of the furnace is added on the basis of the other heating area unchanged, and the overload capacity is stronger. The front and rear arches are framed by water-cooled wall tubes and cast with high-alumina cement, thus avoiding the shortcomings of the original boiler’s tri-fold line arch bricks from breaking and arching collapse during long-term high-temperature grilling, thereby prolonging the service life of the arch.
The inverted “α” arch technology is adopted in the design of the furnace arch of this series of coal-fired boilers. The front arch is high and short, and the back arch is low and long, which increases the burning time of flue gas in the furnace and improves the combustion efficiency. Streamlined rear arch can be in the rear of the grate blowing up the unburned carbon particles thrown forward, so that the coal is easier to ignite, ignition line neat. The applicability of coal is wide. The length of the front and rear shafts of the furnace is longer than that of domestic products of the same model, which prolongs the combustion time of fuel in the furnace, makes the combustion of coal fully, and reduces the carbon content of slag. This series of boilers increase the effective area of grate and enhance the overload capacity of boiler obviously.
SZL series steam boiler adopts two sides of the air inlet, along the grate longitudinal divided into six independent air chamber, each air chamber has an independent air regulating device can be adjusted respectively the size of the air volume of the air chamber, in order to achieve the ideal regulating combustion effect. Coal-fired steam boiler heating area is large, the third return using low resistance high expansion thread smoke pipe, boiler tail equipped with economizer, output, high thermal efficiency, low smoke exhaust temperature. Convection type furnace arch, ignition, combustion, good adaptability of coal.
