The immersive foreign language training mode is a language training method with many years of practical experience and successful examples in the world. It refers to the fully enclosed language training in which the target language is used for teaching. As a learning-oriented team, ZOZEN E-commerce department used the immersive English training method. After many practices, it had effectively improved the English level of our staff to help them provide better boiler services for overseas customers.
As the Spring Festival approaches, ZOZEN Boiler is working at full capacity to complete the production tasks for the whole year with high quality. Therefore, ZOZEN workshops show the busy scene everywhere. The front-line workers are sticking to their own posts to do the work such as cutting materials, quality inspection, boiler assembly in an orderly way to ensure that all of the orders can be completed within the promised period and with high quality.
ZOZEN DZL series packaged boiler is horizontal three-pass water and fire tube chain grate boiler with a wide fuel adaptability to biomass particles, bituminous coal, meagre coal and anthracite. The boiler proper is a longitudinal single drum. The threaded smoke tubes in the drum form the convention heating surface. The drum and water-cooled walls on both sides form the radiation heating surface in the furnace. The combustion equipment adopts the light chain grate. The boiler is reasonably arranged with primary air and secondary air, and is equipped with economizer and dust collector at the boiler end to control the NOx emission concentration below 200mg/m3. Meanwhile, the boiler realizes the stepless speed regulation of the grate via the electric control. There are also the absolute rating alarm and interlocking protection functions to make the boiler safer. It is widely used in the chemical, food, tobacco, textile, printing and dyeing, feed, medicine and building materials industries.
ZOZEN Boiler provided a set of 46MW SZS series gas-fired hot water boiler for Luanchuan County Thermal Power in Henan Province. The boiler combustion chamber adopts the full membrane wall structure with a large radiation heating surface. There are also energy-saving devices at the end of the boiler, which can reduce the exhaust gas temperature and improve the overall thermal efficiency to 95% and above. In addition, with advanced combustion equipment, the boiler's nitrogen oxide emissions can be less than 30mg/Nm3. ZOZEN SZS series hot water boiler is energy-saving and eco-friendly and has a wide range of capacity, which can meet the demands of central heating in various places.
In order to meet the demands of the project to construct a comprehensive PVC resin production plant with an annual output of 60,000 tons in Mekele, Ethiopia, China CEC Engineering Corporation purchased 3 sets of SZL series coal-fired chain grate water tube steam boiler from ZOZEN Boiler who had completed the shipment recently. ZOZEN SZL series coal-fired steam boiler has the sufficient output, a high degree of automation and a high thermal efficiency of over 82%. In order to improve the fuel utilization, there are multiple separate air chambers and air dampers installed at the lower part of the grate to achieve the precise air distribution to meet the demands of air volume needed by fuel in each combustion stage. ZOZEN Boiler also customized the dust removal, desulfurization and denitration equipment at the end of the boiler to ensure that the exhaust gas emission of the boiler could meet the local environmental protection standards.
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.
