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.
The boiler body of WNS series boilers adopts wet-back structure. The combustion, water level, temperature and steam pressure of the boiler are automatically adjusted and protected, which can realize fully automatical operation to ensure safety and reliability. The large-diameter corrugated furnace of this boiler ensures sufficient combustion of natural gas. Combined with an advanced low NOx burner, it can easily achieve the requirement of NOx≤30mg/Nm3. In addition, the boiler is also equipped with energy-saving equipment at the end of the boiler flue, so that the boiler thermal efficiency can reach over 98%.
The body and the middle partition wall of ZOZEN DHL series corner tube hot water boiler adopt membrane water wall complete sealing structure, which greatly reduces the boiler heat loss and improves the boiler thermal efficiency. Meanwhile, the flag heating surface of this series of boilers is designed with patented technology of the same smoke velocity in variable cross-section, so that the flow velocity of the smoke in heated surface between the high temperature zone and the low temperature zone is uniform, reducing the ash accumulation and increasing the heat transfer co-efficiency. In addition, the water circulation structure of DHL series coal-fired boilers is identified the first domestic product in China due to its reliability and advancement. It is widely used because its comprehensive performance has exceeded similar products on the market.
The production processes of textiles such as drying, shaping, printing, etc require stable heat source support. WNS series gas-fired steam boilers feature fully automatic and safe operation to ensure the stability of the heat source during the production process. At the same time, the gas-fired boiler has remarkable energy-saving and environmental protection effects, the thermal efficiency can reach over 98%, and the NOx emission can be as low as 30 mg/m³, which fully meets the needs of the environmental protection era.
Since its establishment in 1988, Wuxi ZOZEN Boilers Co., Ltd. has been committed to the manufacture and research of industrial boilers. At present, ZOZEN Boilers has held many international certifications, such as A-class Boiler Manufacturing License, BR-II Pressure Vessel Manufacturing License, American ASME Standard "S" (Power Boiler) and "U" (Pressure Vessel) Licensing Steel Print, etc. More than 400 kinds of specifications have been formed for gas-fired boilers, biomass boilers, coal-fired boilers and heat-conducting oil boilers. With 30 years of ingenuity, the high-quality products produced by ZOZEN Boilers are selling well at home and abroad, covering all industries such as tobacco, rubber, food, paper making, medicine, electronics, heating and so on, helping many well-known enterprises to upgrade their quality.
