Under the new performance appraisal system, the original assessment criterion should be changed as well. According to the skill level and working competence of every employee, ZOZEN’s leader Mr. Zhang Guoping and department managers divided the front-line staff into five levels: senior technician, technician, senior worker, intermediate worker and primary worker. Different professional titles match different basic salaries to ensure that excellent staff with good skill, diligence and carefulness can get good salaries.

In the process of smelting molten steel, pouring steel ingots, and producing finished castings, a large amount of steam is consumed. The superheated steam generated by the boiler provides the required thermal energy for its process. Through open bidding, ZOZEN stood out among many boiler manufacturing enterprises with its own technical advantages and quality assurance, and provided China Second Heavy Machinery Group Corporation with a large superheated steam boiler, coal industrial boiler supplier.

ZOZEN’s YQ(Y)W series oil-fired/gas-fired vertical thermal oil heater adopts three-pass round coil structure whose end adopts conical coil which can effectively protect the furnace wall at the end of boiler. It is equipped with advanced combustion device with good energy saving and environmental protection performance. This kind of boiler has the characteristics of wide fuel adaptability, low pressure and high temperature, safety and efficiency, high thermal efficiency over 95%, and complete automatic control system which can realize unattended operation.

The IoT solution of ZOZEN Boiler has multiple subsystems such as equipment monitoring, expert management and so on. The boiler operator can monitor the overall operating status of boiler in real time through PC, APP and large screen, which realizes the real-time upload of fault alarms and video monitoring. At the same time, a boiler expert management knowledge base is established for common problems and treatment measures during boiler’s operation, which makes it possible for plan checking and expert online diagnosis, realizes the intelligent and precise management of each production base and further reduces the operating cost and improve the economic efficiency of the enterprise.

The cold working, also known as “iron tailor”, is a kind of comprehensive technology to process metal sheet material, tubular product and proximate matter into various kinds of products without changing the cross section characteristics, which includes straightening, laying off, blanking, cutting, bending, stamping, assembling, riveting, welding, etc. At ZOZEN’s production lines, the number of cold working workers is the largest except that of welding workers, coal industrial boiler supplier.

With thermal efficiency over 82% and NOx emissions less than 100mg/Nm3, ZOZEN DZL series boilers feature high efficiency and low emissions. They adopt single-drum structure and a chain grate. The heat transfer coefficient of threaded smoke tubes is 1.8 times higher than ordinary tubes. In order to expand the capacity, PT. New Hope Indonesia introduced ZOZEN DZL series coal-fired steam boiler to provide efficient and reliable heat source guarantee for feed production.
