ZOZEN WNS series gas-fired and oil-fired boiler is equipped with the advanced condenser, which is a kind of flue gas waste heat exchanger whose working principle is the same as the economizer at the end of the coal-fired boiler. After a condenser is installed at the end of the boiler's flue gas duct, the high-temperature flue gas passes through the flue gas duct and the condenser at the same time, which can heat the water in the condenser, increase the feed water temperature and lower the exhaust gas temperature to achieve the goals of saving fuel and improving the thermal efficiency.
In the drum paring working area of ZOZEN Boiler, the steel plates finishing the rolling will accept the circular seam automatic welding here. After the polishing of welding seam, edge milling, chamfering and other pre-welding treatments, the floating rusts on the surface of steel plates are removed to avoid the generation of a large number of air holes in the welding seam, so as to ensure the welding quality.
The boiler is a kind of special equipment and the compressive strength of boiler can directly affect the boiler safety performance. ZOZEN Boiler insists on putting quality in the first place to conduct the strict strength re-inspection on the boiler manufacturing materials newly purchased in order to ensure the compressive strength of boiler fundamentally and escort the safe operation of boiler.
ZOZEN Boiler has accepted a lot of orders in 2020. In order to meet the order requirements of customers, ZOZEN workers in the workshop are working overtime to catch up with the progress. There is a busy scene in the workshop of ZOZEN Boiler that workers are working hard on their own positions to ensure that the output can keep up with the sales volume. In the workshop, an orderly production scene can be seen with steel spattering and machine tools roaring.
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.
Thermal oil heaters, also known as organic heat carrier boilers, adopt the organic heat carrier as heat medium to realize heat transfer. Due to the high temperature characteristics of organic heat carrier, thermal oil heaters can realize low-pressure and high-temperature heating with an oil output temperature of 350℃. Thermal oil heaters adopt injection-type forced circulation system and heat exchange surface adopts round and square coil structures, which also have a wide fuel adaptability of oil, gas, coal, biomass. ZOZEN Boiler, as a leader in the boiler industry, has improved and upgraded its YQW series, YQL series and YLW series thermal oil heaters applied in the chemical industry to meet the production demands of chemical enterprises. They are equipped with complete operation control and safety monitoring devices which can precisely control the working temperature to ensure boiler's safe operation. They are popular among and favored by chemical enterprises.
In recent days, it has been very hot in Jiangsu province and the temperature of some areas is as high as 39 celsius degree. In spite of the high temperature, workers in the workshops of ZOZEN Boiler are still busy as usual. They are not afraid of hot weather, stick to their positions and use sacrifice and sweat to interpret the meaning of diligence. High temperature can not consume their enthusiasm and hot weather can not stop their steps. Thank all the workers who make sacrifice for the development of ZOZEN Boiler! Today, we focus on these ZOZEN workers under the high temperature and show great respect for them!
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.
