water boilers zip water heaters, ZOZEN general manager Zhang Guoping delivered an important speech on quality management

ZOZEN Boiler Lean Factory Standardization Project officially started orderly. To carry out the standardization work, ZOZEN Boiler with experts from the consulting project team organized a series of internal training courses for the administrative staff and relevant personnel to learn theoretical knowledge, deepen their concepts and master the methods about procedure and specification.

water boilers zip water heaters, During the "Thirteenth Five-Year Plan" period, China's oil refining industry will focus on transformation and upgrading, and continue to enhance comprehensive strength. It will vigorously eliminate backward production capacity and improve the scale and technology of its units. Among them, the boiler as an important piece of energy equipment is indispensable in the petroleum refining process.

Shipment of ZOZEN thermal fluid heater

water boilers zip water heaters, The DZL series coal-fired horizontal three-pass water-fire tube chain grate boiler is pre-assembled boiler which is safe and efficient with a thermal efficiency of over 82%. The boiler body is a single drum longitudinal layout. Thread smoke tubes in the drum form the convection heating surface while the drum and water-cooled walls on both sides form the radiation heating surface of the furnace. The combustion equipment adopts the light chain grate. It has the characteristics of wide coal adaptability, small covering area, convenient installation and high thermal efficiency.

Meanwhile, a set of 36 tph ZOZEN DZL series biomass-fired boiler was in installation in Shandong Province. This boiler system would provide the stable heat source support for the production base of Heze Huihao Textile Co., Ltd. with an annual output of 3,000 tons of knitted fabric and 3,000 tons of rinsed knitted fabric. ZOZEN biomass-fired boiler had a reasonable primary and secondary air ratio and the SNCR intelligent denitrification device at the boiler end, which could ensure that the NOx emission concentration was less than 50mg/Nm3 to meet the environmental protection standards in Shandong Province, helping Huihao Textile realize the ultra-low NOx emission.

The main advantage of ZOZEN’s circulating fluidized bed boiler lies in the direct control of pollutant emission during the combustion process. This type of boiler adopts low-temperature combustion technology. The temperature of normal boiler furnace is as high as 1400-1500°C during combustion, while that of circulating fluidized bed boiler furnace is within a lower temperature range of 800-900°C, which reduces the production of nitrogen oxides (NOx); meanwhile, by adding low-cost limestone to circulating fluidized bed boiler, sulfide (SOx) can be removed during fuel’s combustion.

The longitudinal and circumferential seam welding of ZOZEN adopts advanced submerged arc automatic welding technology to ensure the welding quality. All longitudinal and circumferential seams are subjected to 100% radiographic inspection.

water boilers zip water heaters, ZOZEN will always adhere to technology research and development, and continue to provide efficient and energy-saving boiler systems for enterprises, further contributing to the high-quality development of the domestic fine chemical industry.
