4.2MW YQW series gas-fired horizontal thermal oil heater project in Kazakhstan

ZOZEN has been implementing the Belt and Road initiative all the time. Qingdao United Zhenye Energy Saving Technology Co., Ltd carried out an in-depth cooperation with Kazakhstan on  environmental protection technology of oil fields. ZOZEN provided stable and efficient thermal energy for the project. The first batch of YQW series thermal oil heaters and WNS gas-fired steam boilers has been delivered to Kazakhstan. It indicated that ZOZEN has got the affirmation of users in Kazakhstan again.

The Belt and Road project aims to reduce the problems of environmental pollution and lifting costs through the application of environmental protection technologies. Stable and efficient boilers are necessary to ensure the progress of the project. As a leader of domestic industrial boilers, ZOZEN has perfect production processes with blanking NC rate ≥80%. The steel tube cutting of YQW series thermal oil heaters adopts CNC three-dimensional laser cutting machine and the machining accuracy is controlled within 1 mm. In terms of the welding process, the butt welding of steel tubes adopts the automatic argon arc welding process, and the real-time X-ray imaging of the welding seams is performed to prevent unqualified ones from entering the next process. The production of round coil adopts CNC coil production line, which can be formed at one time without shaping. It prolongs the lifespan of the thermal oil heaters. In order to reduce thermal energy loss, ZOZEN adopts various energy-saving devices to recover the waste heat of high-temperature flue gas, which improves the overall thermal efficiency of the heater to above 95%.
