Patents Assigned to ROAD DRYER, LLC
  • Patent number: 9085858
    Abstract: A road dryer delivers heated air to a surface through an adjustable-width nozzle assembly having nozzle boxes designed to provide turbulent flow of drying air. The road dryer includes a combustion system having a high-pressure atomized fuel burner supplied with diesel fuel by a variable frequency drive fuel pump and a closed-loop air temperature control to limit the temperature of the drying air. The combustion system includes a combustion chamber having a cylindrical inner shell housing the burner and a cylindrical outer shell defining an annular space around the inner shell for the flow of process air. The inner shell has an axially elongated exhaust port aligned with an axially elongated outlet opening of the outer shell to achieve mixing of high temperature exhaust gas with process air. The nozzle assembly is vertically adjustable relative to a chassis of the road dryer between a stowed position and an operating position.
