With the advancement of air pollution prevention plans, Yulin Yushen Coal Yushuwan Coal Mine Co., Ltd. decided to dismantle the existing 3 sets of coal-fired boilers and purchase several sets of gas-fired boiler equipment through public bidding. With strong comprehensive strength, technical advantages and outstanding solutions, ZOZEN stood out from the competitors and smoothly won the boiler purchase bid of Yushuwan Coal Mine
In the past, the impression of a boiler room was a smoky and coal-smudged place. The boiler operator needed to feed the coal manually. Once the furnace door was opened, the flame leaped out of the furnace and the sweat of the boiler operator flowed down with coal ash. Now in the boiler room of ZOZEN gas-fired boiler, the boiler operators can operate the boiler just sitting in front of a computer without getting their clothes dirty.
In the first quarter of the year, faced with the COVID-19 situation, ZOZEN actively sought new development and obtained outstanding achievements in the market development of the gas-fired (oil-fired) boiler, the biomass-fired boiler, the coal-fired boiler and the thermal oil boiler. ZOZEN also signed contracts with many new customers in the chemical, food, and heating industries, which promoted the high-quality development.
Sichuan Kailiwei Technology Co., Ltd. is mainly engaged in the production and sales of tires. Steam as a main heat source plays an important role in the production process of tires. ZOZEN SZS series gas-fired boiler has sufficient and stable output of steam, which can meet the energy requirement of Kailiwei. In addition, the combustion chamber adopts a membrane water wall structure. The flame is burning in slight positive vacuum condition, which insures a clean operating environment. Meanwhile, the spiral finned tube economizer and condenser are equipped to improve the thermal efficiency to more than 98%.
The successful ignition of the boiler comes from meticulous preparations of ZOZEN installation staff. They repeatedly checked and rectified the boiler proper, water supply system, pipelines, and valves before installation. In addition, the installation of the boiler project is carried out during the epidemic period. In the face of the epidemic, ZOZEN actively organized the management and the construction staff, strictly implemented the requirements of the government, strengthened the on-site epidemic control, which not only ensured the health and safety of staff but also smoothly carried out the project and completed the installation of the WNS series gas-fired boiler within the agreed time.
In recent years, there is an increasing concern of biogas. As an advocate for the green development of the industrial boiler industry, ZOZEN overcame the technical difficulties and launched new type biogas-fired steam boilers. With sufficient output and high thermal efficiency, the boilers bot only saved a lot of fuel costs for users but also effectively promoted the development of circular economy.
ZOZEN WNS series gas-fired boiler has a compact structure. The boiler is stable and reliable. It adopts a large-diameter corrugated furnace to ensure sufficient steam storage space and heating area. The heat transfer coefficient of threaded flue tubes is 1.2 times higher than that of ordinary flue tubes. Besides, energy-saving devices were equipped at the tail of the flue to improve the inlet water temperature, reduce the exhaust gas temperature and increase the thermal efficiency to more than 98%, which realized the goal of energy saving and emission reduction for many locomotive depots.
ZOZEN has always been devoted to the improvement of quality and service. According to the actual working conditions of Changchun Huatao, ZOZEN not only reasonably designed the WNS series gas-fired boiler system but also completed the lean Manufacturing of the boiler. From the blanking, drilling, welding to bending, all the processes adopted advanced technology to achieve refined production. It is the rigorous attitude to detail that makes the high quality and high performance of ZOZEN.
