The 6S site management is a prerequisite for enterprises to carry out other work, and it is also the basis of quality management. ZOZEN continues to implement the 6S site management on the production site by following the Seiri, Seiton, Seiso, Seiketsu, Shitsuke and Security principles to ensure a clean, tidy and order production environment and lay a solid foundation for the stability of product quality.
ZOZEN Boiler has accepted a lot of orders in 2020. In order to meet the order requirements of customers, ZOZEN workers in the workshop are working overtime to catch up with the progress. There is a busy scene in the workshop of ZOZEN Boiler that workers are working hard on their own positions to ensure that the output can keep up with the sales volume. In the workshop, an orderly production scene can be seen with steel spattering and machine tools roaring.
The welding of horizontal fixed tubes is to weld the tubes which are put in the horizontal or nearly horizontal position. This kind of welding includes three spacial positions: upright, vertical and horizontal (all-position), which puts forward high requirements for the welding technology. Facing the difficulties brought by welding appearance requirements, curvature of tube joint, and small tube diameter, ZOZEN workers are skilled in welding to ensure the welding quality to effectively extend the service life of boilers.
Thermal oil heaters, also known as organic heat carrier boilers, adopt the organic heat carrier as heat medium to realize heat transfer. Due to the high temperature characteristics of organic heat carrier, thermal oil heaters can realize low-pressure and high-temperature heating with an oil output temperature of 350℃. Thermal oil heaters adopt injection-type forced circulation system and heat exchange surface adopts round and square coil structures, which also have a wide fuel adaptability of oil, gas, coal, biomass. ZOZEN Boiler, as a leader in the boiler industry, has improved and upgraded its YQW series, YQL series and YLW series thermal oil heaters applied in the chemical industry to meet the production demands of chemical enterprises. They are equipped with complete operation control and safety monitoring devices which can precisely control the working temperature to ensure boiler's safe operation. They are popular among and favored by chemical enterprises.
ZOZEN YQW series horizontal thermal oil heater adopts multi-loop coil structure with good safety performance and sufficient heating surface. Meanwhile, ZOZEN Boiler can also design the waste heat recovery system for users to ensure that boiler's thermal efficiency can reach 95% and above. What's more, automatic control system also ensures the safe and stable operation of thermal oil heater to realize the sustainable high-temperature and low-pressure heating supply. In addition, ZOZEN’s gas-fired thermal oil heater is equipped with advanced low-nitrogen burner to ensure that boiler's NOx emission is lower than 30mg/Nm3 to achieve the excellent performance in environmental protection.
ZOZEN guides and cultivates different kinds of talents according to their different characteristics and laws of growth. In late July, ZOZEN Boiler launched a three-day job training program for new graduates, which was held by the vice general manager and boiler designer, Zhu Qiuping. As a senior boiler engineer, vice general manager Zhu has more than 30 years of experience in boiler design, especially in designing large-scale circulating fluidized bed boiler and gas-fired boiler. He is now the head in charge of ZOZEN Boiler's R&D and design department and is one of the representative persons of ZOZEN Boiler's "soft power".
The shipment of ZOZEN YQW series thermal oil heater for Ningde New Energy Co., Ltd. Equipped with an advanced burner, this series of boiler can realize fully automatic operation, including automatic combustion, automatic adjustment of the liquid level of the expansion tank, outlet temperature, flow rate and automatic protection. Meanwhile, the PLC control system is easy to operate. Various kinds of settings can be completed through the intelligent man-machine interface.
Recently, ZOZEN delivered the thermal oil heaters for Hengfa Energy Saving Technology. As a leading industrial boiler manufacturer, the thermal oil heaters of ZOZEN have wide adaptability of fuels, are suit for natural gas, coal gas, marsh gas, diesel, light oil, etc. The heat exchange surface adopts three-pass round coil tube structure, which features more sufficient heating surface. The heaters are also equipped with the advanced burners to ensure the NOx emission is below 30mg/m3.
