Boiler is an important part in the social production field. The boiler production should be more scientific and professional. Welding is a very important step in the production of boilers and welding technology in the boiler manufacturing process is also related to other manufacturing industries in any country. ZOZEN has always encouraged the front-line welding workers to improve their skills and quality to improve the welding technology of ZOZEN Boiler.
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.
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.
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.
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.
For decades, ZOZEN boilers has always guided the manufacturing quality of industrial boilers and established the technological standards of blanking digitization, automation of welding and assembly moulding. The full-automatic CNC tube bending production line greatly improves work efficiency and quality, providing a powerful guarantee for creating first-class products.
