As a traditional industrial boiler manufacturer, ZOZEN not only pays attention to the quality of products, but also keeps up with the changing technological times. Out of the outbreak of COVID-19, a face-to-face communication with interviewees is not available. In response to the situation, ZOZEN applied video interview to recruit new employees and had good results.
In recent years, with the continuous development of "the Belt and Road", China's manufacturing industry has gradually occupied the economic market of Sri Lanka. Sri Lanka Kaka's delegation had conducted a conprehensive investigation of industrial boiler manufacturers in China to choose a good supplier. Through the collection and analysis of the boiler market data in China, ZOZEN stood out with prominent quality in industrial boilers. After preliminary communication, the delegation was attracted by ZOZEN's professionalism and decided to conduct a fied inspection.
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.
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.
Shenyang Third Thermal Heating Co., Ltd. is one of the largest companies of the central heating industry in Shenyang. The body and the middle partition wall of ZOZEN DHL series corner tube hot water boiler adopt membrane water wall complete sealing structure, which greatly reduces the boiler heat loss and improves the boiler thermal efficiency. Meanwhile, the flag heating surface of this series of boilers is designed with patented technology of the same smoke velocity in variable cross-section, so that the flow velocity of the smoke in heated surface between the high temperature zone and the low temperature zone is uniform, reducing the ash accumulation and increasing the heat transfer co-efficiency.
In the petroleum industry, steam is the main factor affecting the energy consumption of enterprises. Jinxi Petrochemical is affiliated to China National Petroleum Corporation. ZOZEN provided the company with SHL series field assembled water tube steam boiler. This series of boilers has wide coal adaptability, the boiler water circulation adopts all-natural circulation, and each heating surface has relatively independent down comers to supply water, ensuring the safety of the overall water circulation. The large furnace design can extend the residence time of the flue gas in the furnace to make the full combustion of the fly ash and combustible gas. In addition, the flag pattern heating surface absorbs the temperature of the flue gas to a large extent, which improves the thermal efficiency of the boiler.
SZS series boiler is designed with longitudinal double drums and " D " type chamber structure. Furnace is placed on the right and convection tube bank is on the left, super heater is arranged at convection tube bank. The body is fixed on the basement by middle and both end flexible supports and make the boiler expand horizontally sideways. Around the furnace is membrane water cooling tube wall. Furnace and tube bank are totally separated by the membrane water tube cooling wall at the left side of the furnace. The back part of bundle is sparse shift structure, front part is aligned structure. Smoke from furnace outlet enters re-burning chamber, convection tube bank area and then from left front part enters spiral fine coil economizer and condenser, and finally is discharged to atmosphere through chimney.
