Jiangsu Ruixin Metal Products Technology Co., Ltd. was established in 2007. It mainly produces galvanized steel strip, cold and hot rolled steel strip and extended products, such as galvanized square pipe, round pipe, light steel keel, cable armoring material, C Shaped steel is widely used in building materials, photovoltaics, building decoration and agricultural greenhouses. In 2019, the Jiangsu Provincial Government issued an optimization plan for the transformation and upgrading of the iron and steel industry, which promoted iron and steel enterprises to further innovate production processes and upgrade equipment around intelligent manufacturing and green manufacturing. In order to actively respond to this policy plan, Ruixin Metal introduced an environmentally friendly WNS series three-pass gas steam boiler to Taiguo Boiler to meet the heating demand of its metal manufacturing production line and achieve good energy saving and emission reduction effects.

Taiguo's WNS series gas-fired steam boiler has the characteristics of sufficient output, high thermal efficiency and outstanding environmental protection performance. This WNS series steam boiler adopts a three-pass structure, combined with a full-wave furnace and a threaded smoke tube, which can effectively extend the residence time of high-temperature flue gas and improve heat transfer efficiency. Together with the economizer and condenser at the end of the boiler flue, the overall thermal efficiency of the boiler can be increased to over 98%. It is worth mentioning that Taiguo WNS series boilers also use advanced low-nitrogen combustion technology to reduce the nitrogen oxide content in the exhaust gas of the boiler to below 30mg/Nm3 in order to meet the NOx emission standards stipulated by the local environmental protection department. At present, Taiguo WNS series boilers have been favored by enterprises in various industries due to their excellent thermal efficiency and environmental protection performance, and are a star product of Taiguo.
