Founded in 2002, Wujiang XinYi Textile Co., Ltd. is a joint-stock private enterprise integrating production and trade of various kinds of high-end fabrics. With the expansion of business, XinYi Textile introduced the ZOZEN biomass-fired boiler. This series of steam boiler is a horizontal chain grate boiler. It has excellent safety performance. The extremely low water level electrode can effectively prevent boiler water shortage accidents caused by extremely low water level operation in manual mode and strengthen the safety protection of water level control.
During the outbreak of coronavirus, ZOZEN completed the production commissioning of two sets of boilers, YY(Q)L-17500Y(Q) and SZS30-1.25-Q, for Luhua Group. Recently, ZOZEN overcame all these obstacles and delivered the boilers on time.
The skid mounted steam boiler is to place all the equipment such as the boiler proper, economizers, burners, valve instruments, electric control cabinet, water treatment, economizer circulating pumps, feeding pumps, deaerators on one or two skids to form an integral movable boiler system. All the pipes and valves on the skid have been installed, furthermore, the connecting pipes between the skids have also been installed in the factory, which can save plenty of costs for clients. This kind of boiler is especially suitable for the food industry, the chemical industry, the textile industry, the medicine industry, the rubber industry, the building materials industry and so on.
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.
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.
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.
This kind of heater adopts three pass circular tube design for sufficient heating surface, and the waste heat boiler and energy-saving device disposed at the tail of the heater can greatly reduce the loss of thermal energy, the thermal efficiency can be as high as 95% or more. Advanced low NOx burner can achieve NOx emissions below 30mg/Nm³. And the operation of the thermal oil heater can realize full automatic control, and can automatically adjust the combustion, high tank level, outlet temperature and flow to ensure the safe operation. This series of thermal oil heaters are favored by all walks of life in the chemical, rubber and food industries.
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.
