Recently, as a leading enterprise in the domestic industrial boiler manufacturing industry, ZOZEN has successfully passed the examination of Jiangsu Market Supervision and Administration Bureau and has acquired the permission to engage in the installation, maintenance and reconstruction project of pressure-bearing special equipment with a sub project of boiler installation (A grade), which is valid until the August 7, 2024.
hotel gas pressure water tube boiler supplier, The SZL series coal-fired steam boiler is safe and efficient with a thermal efficiency of over 82%. It is one of ZOZEN’s patented products. This product is composed of upper and lower parts. The upper part is the heating surface of the body while the lower part is the combustion equipment. The capacity is 4-35 tph. It is a horizontal double drum longitudinal chain grate boiler.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, hotel gas pressure water tube boiler supplier.
ZOZEN SZS series boiler body is designed with D-type chamber combustion structure. The furnace is on right side and the convection heating surface is on left side. The membrane type structure is adopted for the circumference of the furnace body, the wall between the furnace and the convection zone, the front and rear walls of boilers body. The furnace pressure is designed to be greater than 6000Pa.
In terms of welding technology, ZOZEN longitudinal and circumferential seam welding adopts advanced automatic submerged arc welding technology, and 100% X-ray detection is carried out on the welding seam to ensure the welding quality. The welding of the smoke tube and tube sheet adopts pre-expansion first to eliminate the gap between the tube and tube sheet, and then adopts the automatic argon arc welding technology, which can effectively eliminate the stress and extend the service life of the boiler.
Moreover, ZOZEN professionals provide full guidance from the installation and the trial operation of the boiler to the training of the boiler operator, so that each user can enjoy one-stop worry-free service from pre-sales to after-sales, hotel gas pressure water tube boiler supplier.
