2 tph DZL series biomass-fired chain grate steam boiler project for the food industry

Bashi Chuanzhen Agricultural Development (Yiliang) Co., Ltd. is a raw materials processing base established by Sichuan Bashi Chuanzhen Food Co., Ltd. in Yiliang County, Yunnan Province. In the processing of agricultural products, blanching, sterilization and other processes need the stable heat supply provided by industrial boilers. A set of industrial boiler with sufficient output and stable heating has a direct influence on the daily production of the food enterprise. Therefore, Bashi Chuanzhen Agricultural Development (Yiliang) Co., Ltd. attached great importance to the purchasing of the industrial boiler. After having the in-depth communication with ZOZEN's professional technicians for many times, the company decided to order a set of DZL series biomass-fired steam boiler.

ZOZEN DZL series biomass-fired steam boiler adopts the longitudinal single-drum structure and grate firing method. Analyzing the characteristics of different biomass fuels and combing with the actual demands of customers, ZOZEN technicians optimize the feed hopper, width and length of the grate, rotating speed of the grate gear reducer, place and direction of the secondary air inlet of the biomass-fired boilers, which can ensure the sufficient combustion of biomass particles and effectively improve the combustion efficiency. Meanwhile, in order to strengthen the heat transfer and improve the boiler thermal efficiency, DZL series biomass-fired steam boiler adopts the threaded smoke tube developed by ZOZEN Boiler, whose heat transfer coefficient is 1.8 times higher than common smoke tubes. The boiler thermal efficiency can reach 88% and above, which can meet the daily production demands of the enterprise.
