The body of SZL type coal fired boiler is composed of longitudinal upper and lower drum and convection tube bundle. There are water-cooled walls around the combustion chamber and the front and rear arches are made of water-cooled walls as skeleton castable refractory castables. The service life of furnace arches is longer. The left and right sides of the body are all membrane type water-wall structure, which has good sealing and small heat dissipation loss to ensure the safe and efficient operation of the boiler. Widely used in textile factory, garment factory, chemical factory, food factory, pharmaceutical factory, paper mill, brewery, water washing factory and other industries, quick loading structure, for customers to bring convenient installation, reduce the investment cost.
The thermal efficiency of ZOZEN SZL coal-fired boiler can reach more than 82%. The length of the front and rear axles of the boiler is longer than that of the domestic products of the same type, which prolongs the combustion time of fuel in the furnace, makes the coal burning fully, and reduces the carbon content of slag. With the increase of grate effective area, the boiler overload capacity is obviously enhanced. At the same time, two-way air inlet is used, and six independent air chambers are arranged longitudinally along the grate. The air volume of each air chamber can be adjusted separately by independent air regulating device between each air chamber, so as to achieve the best adjustment of combustion effect.
SZL type chain grate coal fired boiler has high efficiency, strong overload capacity and wide adaptability of coal. The overall design of the boiler is reasonable, the heating area is large, the flue gas flow is long, the heat transfer effect is good, and the exhaust temperature is low. Therefore, this series of boilers have higher thermal efficiency, lower operating cost and more economical way of use. This series steam boiler is equipped with high quality instrument valve and other safety accessories; the whole equipment is safe and durable, stable and reliable operation. Water treatment can be added to reduce bile scale, and the boiler is safe and energy saving.
ZOZEN coal fired boilers have a wide range of adaptability. After continuous upgrading and optimization, coal-fired steam boiler is not only energy saving and environmental protection, but also in line with environmental protection standards.
