The production processes of the feed industry involve granulation, conditioning, drying, disinfection, etc. These processes often require boilers to provide steam, so many feed plants generally use steam boilers. A British company is mainly engaged in the processing of feed and concentrated the research and development of the feed. This time, the company cooperated with Xinli boiler in boiler selection. Xinli boiler provided a 6-ton DZL series coal fired steam boiler according to the requirements of the company’s feed production processes. The rated evaporation capacity of the furnace type is 6t/h, the steam temperature is 194℃, and the feed water temperature is 20℃。

Xinli boiler's DZL series chain grate coal fired steam boilers are longitudinally arranged with a single drum, and the arch tube plate and threaded smoke tube structure are first adopted in China. Threaded smoke pipe is an efficient heat transfer element studied by Xinli boiler for many years. After continuous optimization, its heat transfer coefficient is 1.8 times higher than that of ordinary smoke pipe, which increases heat conduction. In terms of manufacturing process, Xinli boiler adopts the welding process of pre-expansion to eliminate the gap between the pipe and the tube plate, and then argon arc automatic welding to effectively eliminate the stress and prolong the service life of the boiler. The above advantages make Xinli boiler one of the popular industrial boiler brands in the feed industry, which is also an important factor why the UK feed company chose to cooperate with Xinli boiler.
