pharmaceutical industry natural gas steam water boiler supplier, ZOZEN boiler makes a wonderful appearance at Shanghai international drying technology equipment exhibition

On August 25 of 2020, Wuxi ZOZEN Boilers Co., Ltd. officially held the quality management mobilization meeting. The basic design department, research and development department, process improvement department, equipment department, production department, quality assurance department, purchasing department, material planning department, all workers at the production lines and related leadership attended the meeting, pharmaceutical industry natural gas steam water boiler supplier.

With years of efforts, ZOZEN has obtained outstanding achievements in the overseas market. Recently, ZOZEN participated in a large photovoltaic industrial chain project in Turkey, which showed that the brand and strength of ZOZEN were recognized by the overseas market.With an annual output of 500MW, the photovoltaic industrial chain project in Turkey is a key project of the Belt and Road China-Turkey cooperation project. On December 12, the opening ceremony of the project was held at the Başkent OIZ Industrial Park in Ankara.

The base of ZOZEN DZL series coal-fired steam boiler adopts separate air chambers to keep the fuel on the grate in a good combustion state. The air dampers further ensure the sufficient combustion of the fuel and improve the fuel utilization. In addition, through advanced electrical control, it can realize the stepless speed regulation of the grate, as well as limit parameters alarm and interlock protection function to ensure the safe operation of the entire boiler system.

The grate bracket of ZOZEN’s chain grate boilers adopts double-layer structure. The lower layer uses channel steel and the upper layer uses light rail. The upper layer is heated and the lower layer is stressed. It changes the traditional grate bracket using angle steel and friction strips without  deformation. The active grate runs on the light rail with a 72-hour cold test run carried out before leaving the factory to ensure the smooth operation of grate without deviation or jamming.

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.

pharmaceutical industry natural gas steam water boiler supplier, With thermal efficiency over 82% and NOx emissions less than 100mg/Nm3, ZOZEN DZL series boilers feature high efficiency and low emissions. They adopt single-drum structure and a chain grate. The heat transfer coefficient of threaded smoke tubes is 1.8 times higher than ordinary tubes. In order to expand the capacity, PT. New Hope Indonesia introduced ZOZEN DZL series coal-fired steam boiler to provide efficient and reliable heat source guarantee for feed production. 

Be it a firetube, watertube, hot water, or steam boiler, they are all effective and efficient in their own unique ways. To learn in more detail about the differences between boiler types, visit the section on ZOZEN website.
