4 tph DZL coal-fired boiler for cable factory

Yuanda Cable Co., Ltd.---a high-tech company specializing in the research, product and sale of power cables, branch cables and computer cables. The cable manufacturing process includes three processes of mixing, extruding and vulcanizing. During the extrusion process, overheating easily leads to scorching, but when the temperature is too low, it’s hard to gel. In the vulcanization process, bubbles are easily generated when the temperature is too low or too high. The temperature and pressure requirements of every process are different, so the control of cooking temperature and pressure must be precise and adjustable. In 2011, Yuanda Cable had customized a 4 tph DZL coal-fired steam boiler at ZOZEN. This series carries out comprehensive safety monitoring of the boiler’s water level and steam pressure, and it uses boiler safety control technology that complied with EU coal-fired boiler standards to ensure boiler operates more safe and reliable. The automatic and interlocking control technology is used to achieve stepless speed regulation of grate.
