SZL reciprocating grate boiler

Descripción del producto

Zhengzhu SZL-type chain grate coal-fired boiler high efficiency, overload capacity, coal wide adaptability, known as contemporary domestic similar products the best design, with the world's advanced level. The boiler is mainly composed of upper and lower drums, convective tube bundles, water wall pipes, down pipes and manifolds. The upper and lower drums are arranged longitudinally. The combustion equipment adopts chain belt chain grate and is driven by CVT. The boiler body has a vertical upper and lower drum and a convection tube bundle. In the combustion chamber, Φ*1 * 3 pipe is composed of water wall, and the boiler is equipped with soft water separation and continuous sewage device. The drum is equipped with periodic sewage device to ensure the steam quality. Equipped with continuous automatic water supply device to ensure the safe operation of the boiler, the boiler rear layout economizer.
Performance advantage

Unique membrane water wall structure:
The membrane water wall structure used in power plant boiler is used in assembling boiler. The advantage is that the heat transfer area is large, the conduction effect is good, the heat loss is low, the air tightness is good, the furnace wall is not deformed and does not leak.
Innovative front and rear arch structure:
Before and after the furnace wall, the water wall tube down to the upper part of the formation of the front and rear arch, increased the furnace radiation heating surface, overload capacity stronger; before and after the arch to the water wall tube as a skeleton and made of high alumina cement There are broken, arch collapse of the ills, extending the arch of the service life.
Lengthened grate:
The length of the front and rear axle of the grate is longer than that of the domestic product, which prolongs the burning time of the fuel in the furnace, makes the combustion of coal fully and reduces the carbon content of the slag. The effective area of the grate increases, and the boiler overload capacity is obviously enhanced.
Double inlet
There are six independent wind chambers along the longitudinal direction of the grate, and each air chamber has an independent air conditioner to adjust the air volume of each wind chamber separately to achieve the best adjustment of the combustion effect.
