HDRA-RF SERIES BURNERS

HDRA-RF SERIES BURNERS |
The Webster Combustion model HDRA-RF is a multi-fuel register-style burner for asphalt rotary dryers that allows users to shape the flame by automatically controlling the register vanes to optimally fit their rotary dryer and combustion zone. This allows the Webster burner to operate with a shorter flame than products offered by other asphalt burner manufacturers. This flame-shaping capability means the flame will not impinge on the material, and CO can be maintained at much lower levels than currently available. In addition, NOx levels for the HDRA-RF are significantly lower than typically seen in asphalt applications. The Webster Combustion HDRA-RF operates with lower motor HP, an optionally supplied VFD and an inlet air damper, which allows for higher turndown ranges to reduce energy usage and provide greater total energy savings.
The Webster Combustion HDRA-RF burner readily adapts to mount on both Parallel Flow and Counter Flow Dryers, and the burner housing and fan can be installed in multiple configurations depending on space constraints and elevator location. The Webster Combustion HDRA-RF Series Asphalt Burner is capable of burning a wide range of fuels, either separately or simultaneously, including Natural, LP, and low BTU gas, all commercially available grades of fuel oil, and qualified waste oils. A dual manifold combustion head is available for applications firing multiple gas fuels.
A wide choice of burner arrangements is available with the HDRA-RF package burner system. Webster’s engineering team will assist you in designing the best arrangement for your application. Flexibility in design and assembly means that the HDRA-RF can be applied to a wide variety of heater applications.
