Abstract
An asphalt plant including a plurality of asphalt processing components, with a selected first set of the components producing volatile emissions and a selected second set requiring process heat energy. A central burner assembly is connected to the selected second set of components by an insulated duct system for providing heat energy to the second component set. A first duct system is adapted to capture a portion of the volatile emissions produced by the first component set and convey the captured emissions into the central burner for mitigation. The central burner is preferably a media burner incorporating flameless combustion technology as well as an adjustable internal fuel injection system, which results in safer and more controllable combustion. Even with captured fugitive emissions in the inlet air, the fuel injection system keeps the concentration of combustible materials well below the lower flammability limit.
