For these years, Xinli Boiler has focused on the innovative research and development of coal fired boilers, which obtained a number of patent technologies, and achieved efficient and low emission of DZH series coal fired moving grate steam boilers. Its thermal efficiency has been improved to more than 82%, and NOx emission is lower than 100mg/Nm3. DZH series coal fired moving grate steam boiler is a single drum longitudinally arranged boiler. It is the first time to adopt arch tube sheet and threaded smoke tube structure in China. The threaded smoke tube is an efficient heat transfer element researched by Xinli Boiler for many years. After continuous optimization, its heat transfer coefficient is 1.8 times higher than that of ordinary smoke tube, increasing heat conduction. In terms of manufacturing process, Xinli boiler adopts pre expansion for smoke tube and tube sheet to eliminate the gap between tube and tube sheet, and then adopts argon arc automatic welding process to effectively eliminate stress and prolong the service life of boiler. All these advantages make Xinli Boiler one of the most popular industrial boiler brands in the feed industry.

A company founded in 1982 in Nepal, has nearly 200 companies and 30000 employees worldwide, with an annual operating income of more than 8 billion $. It is a member enterprise focusing on the development of food and modern agriculture.This company starting from feed who is one of the first batch of key leading enterprises in agricultural industrialization in Nepal. This time, due to the demand of capacity expansion, the company introduced high-quality and efficient 3 tons DZH series coal fired moving grate steam boiler from Xinli Boiler, for providing efficient and reliable heat source for feed production.The following figure shows the manufacturing of the 3 tons DZH series coal fired moving grate boiler.
