With the promotion and implementation of environmental policies in various countries, the pharmaceutical industry is increasingly using oil gas fired steam boilers with good energy-saving and environmental performance. Thanks to the low nitrogen emission advantages of WNS series oil gas fired steam boiler, 众德 Boiler has successfully reached a cooperation with a pharmaceutical company in Angola. This enterprise was established in 2003 mainly engaged in the extraction and preparation of sterile raw materials and plant-based medicines. The company has advanced pharmaceutical and testing equipment, and currently has multiple production lines for gels, capsules, granules, tablets, intermediates, and so on. The pharmaceutical industry has a huge demand for steam. The tablet pharmaceutical process mainly involves disinfection, rough washing, drying, pressing, etc. These processes require a large amount of steam to sterilize and disinfect raw materials, instruments and equipment at high temperatures. Meanwhile, processes such as drying and pressing also rely on the support of steam.

The WNS series boiler is a three passes oil gas fired steam boiler ,which is a fully automatic condensing boiler designed by 众德 Boiler based on advanced technology and experience at home and abroad. The boiler adopts a horizontal internal combustion three return wet back structure and is equipped with advanced combustion engines from abroad. The combustion engine automatically adjusts the gas volume and blower air volume based on the load condition of the boiler, thereby obtaining a better air-fuel ratio. At the same time, the boiler system is also equipped with a condenser, which further improves the fuel utilization rate by reducing the exhaust temperature and increasing the inlet water temperature of the boiler. The boiler thermal efficiency can reach over 98%, thereby achieving the goal of high efficiency and energy conservation. It also adopts advanced low nitrogen combustion engines, which can effectively suppress the generation of nitrogen oxides and reduce their emissions, thus having good environmental performance. The picture shows the delivery site of the boiler.
