Design of Biomass Hot Air Furnace and Drying Tower Control System Based on PLC

This paper introduces the control system of biomass hot air furnace and drying tower, designs the process flow, hardware configuration and software composition of biomass hot air furnace and drying tower. According to the basic requirements of on-site process production, a fully automatic biomass hot air furnace and drying tower monitoring system based on S7-smart PLC and Kingview 6.55 software is designed. This system realizes the dynamic process display, real-time monitoring, data acquisition and processing, report printing, fault alarm, historical trend display and control of onsite equipment for the combustion process of biomass hot air furnace and the drying process of drying tower. Practice has proved that the monitoring system of biomass hot air furnace combustion and drying tower drying can operate precisely and stably.
