Zhengguo WNS type fuel gas boiler is a boiler product developed in cooperation with German technology, and is one of the implementation sub projects of the World Bank GEF high-efficiency and environmentally friendly boiler project. The R&D team of Zhengguo continuously explores and practices, creatively combining ultra-low nitrogen combustion technology with WNS boiler manufacturing technology, achieving key breakthroughs in core technologies such as staged combustion and FRG flue gas recirculation. NOX emissions can reach 26mg/m ³, approaching the world's strictest boiler emission standards. The technical indicators of the boiler's flue gas blackness, smoke blackness, concentration, noise, etc. are all better than the national first-class regional restrictions. In addition, this model is divided into conventional condensing gas boilers and condensing integrated gas boilers according to the arrangement of auxiliary equipment.

Application industries: hospitals, schools, hotels, government agencies, pharmaceutical industry, food factories, beverage factories, rubber factories, greenhouses, chemical factories, paper mills, building materials industry, clothing and textile factories, washing factories, etc.

Common tonnage: 2 tons WNS steam boiler, 4 tons WNS gas boiler, 6 tons WNS gas boiler, 8 tons WNS horizontal gas boiler, 10 tons WNS gas boiler, 20 tons WNS horizontal gas boiler
