The SZL series steam boiler is a longitudinal double-drum chain grate boiler water tube boiler designed. By Zozen Boilers with advanced technology and combined with its own experience. The 6-35 ton SZL series boiler is composed of upper and lower parts. The lower base of the water pipe steam boiler is the combustion equipment, and the upper part is the heating surface of the body. In order to ensure accurate air distribution, the base design of the Zozen Boilers adopts multiple independent air chambers. Which do not cross air between each other. And through the air regulating door to meet the air distribution requirements of different combustion stages.
At the same time, the boiler furnace is composed of water-cooled wall pipes, front and back arches and hearth. Several return convection tube bundles are arranged at the rear of the chain grate boiler body. Adequately absorb the heat released by combustion. The SZL series chain grate steam boiler system customized by Zozen Boilers has excellent performance. The thermal efficiency is more than 5% higher than similar boiler systems on the market.
Water Tube Boiler Construction
The front and rear water wall pipes of the water pipe steam boiler furnace extend downward to the upper part of the grate to form front and back arches. This not only increases the sealing performance of the boiler, but also increases the furnace volume and heating surface. At the same time, the strength of the rear arch is reinforced. Behind the furnace of this series of boilers product is a combustion chamber, a convection tube bundle, and an economizer at the end. The flue gas enters the tail flue through the furnace, the combustion chamber, the convection tube bundle, and the economizer. And is discharged into the atmosphere through the dust collector, induced draft fan, and chimney.
The front wall of the SZL series water tube boiler is equipped with secondary air, which is controlled by a valve and is put into use when fuel is being used. It can effectively strengthen the combustion, make the fuel fully burn out, and improve the combustion efficiency. A higher feed port is used to meet the fuel demand. SZL type steam boilers are widely used in schools, textile factories, garment factories, printing and dyeing factories, restaurants, food factories, beverage factories, soy products factories, meat products factories, canneries, wineries, pharmaceutical factories, packaging factories, building materials factories, coatings Factories, swimming pools and other enterprises and institutions.
The water pipe steam boiler adopts double-sided air intake, and six independent air chambers are arranged along the longitudinal direction of the grate. There is an independent air regulating device between each air chamber, which can adjust the air volume of each air chamber separately. In order to achieve the best adjustment combustion effect. The boiler adopts a streamlined rear arch design. Which can throw the unburned carbon particles blown up from the middle and rear part of the grate to the front part. Make the coal easier to ignite, and the fire line is neat. Wide applicability of coal types.
