The coal fired chain grate boilers’ membrane water-cooled wall structure has a large heat transfer area, good conduction effect, low heat loss, good airtightness, no deformation of the furnace wall, no ash leakage. This coal-fired boiler grate extends the burning time of fuel in the furnace chamber, so that the coal is fully burned, reducing the carbon content of the slag; increases the effective area of the grate, the boiler overload capacity is significantly enhanced.
SZL series assembled chain grate boiler with a double pot longitudinal arrangement, combustion method with chain grate layer combustion. After the furnace chamber for the combustion chamber, convection tube bundle, the end of the coal conservator (or air preheater). Flue gas through the furnace, combustion chamber, convection tube bundle, coal conservator (or air preheater) into the tail flue, through the dust collector, induced draft fan, chimney exhaust into the atmosphere.
Coal fired boiler supplier‘s boiler chamber front and rear wall water-cooled wall tubes down to the upper part of the grate to form the front and rear arches, which not only increases the sealing performance of the boiler, but also increases the chamber volume and heating surface, while strengthening the strength of the rear arch.
ZOZEN’s coal fired chain grate boilers have various advantages such as sufficient output, high thermal efficiency, stable and reliable operation, strong overload capacity, wide fuel applicability, energy saving and environmental protection, etc. This series of coal-fired boiler products are widely used in pharmaceutical, chemical, food, feed, rubber and other industries.
