DZL coal steam boiler produced by ZOZEN is designed by our company according to the needs of consumers and the advantages of similar products. It has the advantages of high reliability, high thermal efficiency and strong overload capacity, etc. It is the best designed product of the same kind in China.
Coal Boiler Performance Advantages
- By drawing part of the rising tube on both sides of the collector box to the furnace chamber, and then introducing the bottom of the pot barrel and the bottom of the pot barrel covered with insulation material to form the furnace top heating surface, the novel furnace structure successfully solved the problem that the bottom of the pot barrel was directly exposed to high temperature flame radiation, so as to avoid “bulge” defect.
- DZL chain grate boiler arch design adopts the “Xi ‘an Jiaotong University National Science and Technology Progress Second prize” the latest scientific research achievements, the rear arch low and long, the exit section for the reverse tilt, the front arch Angle of 45° and the back arch phase echo, the formation of inverted “” flame, is conducive to the combustion of inferior coal, coal adaptability.
- Design push-pull type gate deashing device. The gate adopts heat resistant cast iron finishing sealing structure, so as to effectively prevent secondary combustion deformation and exhaust air leakage.
- The two wing flue setting, so that the smoke smoothly into the front smoke box, so that the front tube plate temperature is the same and lower than 600℃, maximum to avoid DZL chain grate coal boiler tube plate crack due to temperature stress.
DZL Coal Steam Boilers in Indonesia
In feed production, the process of pelleting and extrusion of feed requires a large amount of efficient and reliable steam. In a feed mill, it is very important to keep the steam equipment in good condition and choose the right type of equipment. DZL series of high quality and efficient coal-fired steam boilers of ZOZEN boiler have a thermal efficiency of over 82% and NOx emission of less than 100mg/Nm3.
DZL series chain grate boiler is single boiler tube longitudinal arrangement, in the domestic take the lead to adopt arch tube plate and threaded pipe structure, the special threaded pipe heat transfer coefficient is 1.8 times higher than ordinary pipe. In terms of manufacturing technology, ZOZEN boiler adopts pre-expansion for smoke pipe and tube plate to eliminate the gap between the pipe and tube plate, and then adopts argon arc automatic welding technology to effectively eliminate the stress and extend the service life of the boiler. The above advantages make ZOZEN boiler one of the most popular industrial boiler brands in the feed industry.
Over the years, ZOZEN Boiler has focused on the innovative research and development of chain grate, and obtained a number of patents. As a coal-fired boiler manufacturer, we have DZL series, SZL series, SHX series circulating fluidized bed boiler, DHX series circulating fluidized bed boiler, DHL series Angle and SHL series coal fired boiler. Therefore, the products will be shipped to customers after strict inspection. If you are interested in our products, please contact us for consultation.
