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.
Affected by the global COVID-19 conditions, many enterprises change their offline business to online business. To solve the problem of communicating with overseas customers, ZOZEN Boiler has purchased a complete set of video conference equipment to keep a smooth communication with overseas customers. Recently, ZOZEN Boiler has organized a video conference with a Korean customer about the circulating fluidized bed boiler project. ZOZEN's general manager Zhang, sales vice general manger Liu, boiler designer Yang and domestic sales manager Wang attended the conference.
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 SZL series chain grate boiler for R.R.P AGRO FARM.SZL series of biomass-fired boiler is one of ZOZEN’s patented products. It has the characteristics of wide fuel adaptability, less occupied area, convenient installation and high thermal efficiency. ZOZEN biomass-fired boiler is suitable for a variety of fuels such as biomass pellets, wood blocks, palm shell, rice husks, corncobs and wood waste. In order to improve the overall efficiency of the boilers, ZOZEN rationally designs different feeding systems according to the characteristics of different biomass fuels. By extending the furnace arch, increasing the height of the furnace, adjusting the width and length of grates, etc., ZOZEN has taken the lead in solving the problems commonly occurred in conventional biomass-fired boilers, such as furnace arch burning down, furnace door burnout, backfire in hopper tempering and tube shell coking.
As a traditional industrial boiler manufacturer, ZOZEN not only pays attention to the quality of products, but also keeps up with the changing technological times. Out of the outbreak of COVID-19, a face-to-face communication with interviewees is not available. In response to the situation, ZOZEN applied video interview to recruit new employees and had good results.
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.
ZOZEN CNC lathe can automatically measure and compensate for tool wear and other errors during machining, improve production efficiency and product quality, reduce scrap rate and costs.
