Industrial boilers have experienced numerous technological innovations. ZOZEN has optimized the boiler manufacturing process to make the boiler manufacturing more precisely. For decades, ZOZEN boilers have always guided the manufacturing quality of industrial boilers. With rich welding experience, the welding operator of ZOZEN greatly improves the welding quality, providing a powerful guarantee for creating first-class products.
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.
Founded in 2002, Wujiang XinYi Textile Co., Ltd. is a joint-stock private enterprise integrating production and trade of various kinds of high-end fabrics. With the expansion of business, XinYi Textile introduced the ZOZEN biomass-fired boiler. This series of steam boiler is a horizontal chain grate boiler. It has excellent safety performance. The extremely low water level electrode can effectively prevent boiler water shortage accidents caused by extremely low water level operation in manual mode and strengthen the safety protection of water level control.
During the outbreak of coronavirus, ZOZEN completed the production commissioning of two sets of boilers, YY(Q)L-17500Y(Q) and SZS30-1.25-Q, for Luhua Group. Recently, ZOZEN overcame all these obstacles and delivered the boilers on time.
On Christmas Eve 2019, General Manager Mr. Zhang Guoping signed an agreement with Shir Baz Kaminzada, CEO of Baheer group from Afghanistan on the papermaking steam boiler project and established a friendly and cooperative relationship. ZOZEN took another firm step towards the internationalization strategic goal! The heating and dissolving, machine shaping, black slurry concentration and squeeze drying of the chemicals in the pulping process all require heat sources, so the boiler is the main driving force for the production of the paper mill.
Boiler X-ray inspection is based on the difference in the absorption of X-rays by different material thicknesses. The X-ray inspection of boiler is to show the internal defects of materials, parts and welds from the film and image by using the X-ray perspective photography and real-time imaging of industrial television. Such as crack, shrinkage cavity, air hole, slag inclusion, undissolved, incomplete penetration and etc. The quality of materials or products can be evaluated by observing the nature, size and position of defects, so as to prevent major accidents caused by internal defects and poor processing of materials.
A boiler hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The main purpose of the hydrostatic test is to identify the tightness and compressive strength of the pressure components of the boiler, including but not limited to welding lines, flange joints and tube expansion joints, and visually observe the deformation of the pressure components. Practice has proved that the boiler hydrostatic test can detect defects in boilers, and the corresponding measures can be taken accordingly. Therefore, it is an important step and means to ensure the safe operation of the boiler.
