On Christmas Eve 2019, General Manager Mr. Zhang Guoping signed an agreement with Shir Baz Kaminzada, CEO of Baheer group from Afghanistan on the papermaking steam boiler project and established a friendly and cooperative relationship. ZOZEN took another firm step towards the internationalization strategic goal! The heating and dissolving, machine shaping, black slurry concentration and squeeze drying of the chemicals in the pulping process all require heat sources, so the boiler is the main driving force for the production of the paper mill.
Boiler X-ray inspection is based on the difference in the absorption of X-rays by different material thicknesses. The X-ray inspection of boiler is to show the internal defects of materials, parts and welds from the film and image by using the X-ray perspective photography and real-time imaging of industrial television. Such as crack, shrinkage cavity, air hole, slag inclusion, undissolved, incomplete penetration and etc. The quality of materials or products can be evaluated by observing the nature, size and position of defects, so as to prevent major accidents caused by internal defects and poor processing of materials.
A boiler hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The main purpose of the hydrostatic test is to identify the tightness and compressive strength of the pressure components of the boiler, including but not limited to welding lines, flange joints and tube expansion joints, and visually observe the deformation of the pressure components. Practice has proved that the boiler hydrostatic test can detect defects in boilers, and the corresponding measures can be taken accordingly. Therefore, it is an important step and means to ensure the safe operation of the boiler.
CMU short for China Medical University, located in Shenyang, Liaoning, is a university jointly established by the National Health and Family Planning Commission, the Ministry of Education, and the Liaoning Provincial Government. The DHL series hot water boiler provided by ZOZEN is the second-generation corner tube hot water boiler. This return visit, ZOZEN carried out all-round maintenance for the boiler to ensure the safety and stability of its heating in this winter.
Vietnam has abundant coal resources, including anthracite, bituminous coal, lignite, and peat. Vietnam anthracite has the characteristics of high calorific value, low ash, low nitrogen, low phosphorus and low sulfur. ZOZEN SZL series coal-fired boiler has wide fuel adaptability and sufficient fuel combustion, and has established an excellent reputation in the Vietnamese market.
ZOZEN will held regular exchange training sessions. On the one hand, it helps employees to better understand the company's business, speed up the company's development process, and resolve any skills gaps. On the other hand, training can stimulate employees' confidence and improve their subjective initiative. Employees gained a lot from this gas-fired boiler knowledge training, laying a good foundation for upgrading higher quality products.
Recently, the expert group from National Industrial Boiler Quality Supervision and Inspection Center visited ZOZEN, and the two sides conducted in-depth exchanges on issues such as the future development trend of the industrial boiler industry. Led by Mr. Zhang Guoping, General Manager of ZOZEN, they visited the modern production base of ZOZEN.
ZOZEN WNS series gas-fired (oil-fired) boilers adopt large diameter corrugated furnace for sufficient fuel combustion; euqipped with low NOx burner, the thermal efficiency is over 98%, and the ultra-low emission of NOx is easy to achieve.
