SZL type coal fired boilers, with high efficiency, strong overload capacity and wide adaptability of coal types, is honored as the best design scheme of contemporary domestic similar products and has advanced level in the world. The chain grate coal fired boiler manufacturer is widely used in heating companies, textile factories, clothing factories, chemical plants, food factories, pharmaceutical factories, paper mills, wineries, water washing factories and so on.
The coal fired boilers is mainly composed of upper and lower boiler tube, convection tube bundle, water wall tube, drop tube and set box. The upper and lower boiler tube is arranged longitudinally. The combustion equipment adopts chain belt type chain grate and drives by stepless variable speed device. The boiler body of SZL type consists of vertical upper and lower boiler tubes and convection tube bundles. Water cooling wall is arranged around the combustion chamber, and the front and rear arches are made of water cooling wall as the skeleton casting refractory castable, and the furnace arch has a longer service life. On the left and right side of the body is the all-film water-cooling wall structure, which ensures the safe and efficient operation of the boiler with good sealing and small heat dissipation loss.
Coal fired boiler adopts original membrane water-cooling wall structure with large heat transfer area, good conduction effect, low heat loss, good air tightness, no deformation of furnace wall and no ash leakage. This series of boilers increase the radiant heating surface of the furnace, which has strong overload capacity and prolongs the service life of the front and rear arches of the boiler. Using the extended grate design, full combustion, boiler overload capacity enhanced.
SZL type coal fired boilers has good regulating performance, sectional air supply and good sealing performance. It can effectively control the air supply of each combustion section to achieve the best combustion regulation effect. The design of tube wall and the application of cast iron economizer further reduce the heat loss of exhaust smoke and make the boiler more efficient. After being closed with the supplementary heating surface at the site, only the lower furnace wall can be put into operation, with short installation period and less cost.
The products of ZOZEN boiler are in more than 80 countries, and more than 10000 cases are accumulated. This benefits from our excellent quality and the full life cycle service we offer from pre-sale consultation, solution design, equipment manufacture, erection instruction, spare parts supply to the production line operation.
