ABSTRACT:
A control system for a compact efficient air flotation dryer with a built-in afterburner for combustion of solvent-laden air within a dryer-enclosed combustion chamber. An internal exhaust fan propels internal solvent-laden air across a burner where it combusts, causing a heat rise. Heated, combusted air is routed to a recirculating supply air fan which provides pressurized heated air for air bars for drying a web. Heated air in excess of that required to dry the web is vented externally and helps to maintain desired solvent concentration levels. Variable parameters such as fan speed, burner temperatures, air box pressures, exhaust air rate, solvent concentration, supply air flow, supply air temperature and damper position are monitored, and the components are actuated to effect a high level of clean up efficiency. The control system provides for the coordinated control of the exhaust fan speed, damper positions, and burner firing. The control system utilizes a computer in real time processing to monitor and control the electrical and electromechanical components.
