Abstract
A rail heating assembly including a series of individual heating modules is operable to raise and maintain the temperature of rails of a railroad track to reduce bending and deforming of the rails due to variations of atmosphere conditions. The heating module includes a series of burners with attached radiator plates so as to provide convective and radiant energy to heat the rails. The heating module includes an outer shell and a Venturi-shaped inner shell to surround the rail, with a series of burners attached to one end providing a stratified flame to heat the rail. A series of radiator plates mounted to the inner shell are heated by the flame, and the radiator plates radiate thermal energy towards the rail.
Claims18
A mobile rail heating assembly comprising:
- a railway vehicle;

- environmental sensing means connected to said central processing unit to monitor atmospheric conditions surrounding the rail, said environmental sensing means comprising first thermometer to measure air temperature, a second thermometer to measure rail temperature, and a barometer to measure atmospheric pressure;
- a mechanical deployment arm connected to said control assembly and said railway vehicle;
- and
- a heating module connected to said mechanical deployment arm and said control assembly, said heating module including:
- a housing;
- and
- at least one convective hot air generator connected to said housing;
- and
- wherein said central processing unit controls the operation of said heating module according to the atmospheric conditions.
A mobile rail heating assembly comprising:
- a railway vehicle;
- a control assembly mounted on said railway vehicle;
- a mechanical deployment arm connected to said control assembly and said railway vehicle;
- and
- a heating module connected to said mechanical deployment arm and said control assembly, said heating module including:
- a C-shaped housing having a first and second end, said housing including an outer shell and an inner shell to substantially surround the rail;
- a louver integrated with said inner shell, said louver allowing ambient air to flow into the region surrounded by said inner shell;
- at least one burner connected to the first end of said housing to provide a flame within a region surrounded by said inner shell;
- and
- a pair of frame brackets connected to said inner shell;
- at least one radiator plate attached between said frame brackets;
- wherein said flame heats the rail and said radiator plate;
- and
- wherein said radiator plate further radiates heat toward the rail.
A mobile rail heating assembly comprising:
- a railway vehicle;
- a control assembly mounted on said railway vehicle including a central processing unit and environmental sensing means connected to said central processing unit to monitor atmospheric conditions surrounding the rail, said environmental sensing means including a first thermometer to measure air temperature, a second thermometer to measure rail temperature and, a barometer to measure atmospheric pressure;
- and
- a mechanical deployment arm connected to said control assembly and said railway vehicle;
- and
- a heating module connected to said mechanical deployment arm to heat a rail, said heating module including:
- a C-shaped housing having a first and second end, said housing including an outer shell having a plurality of burner apertures and an inner shell having a plurality of flame apertures, and wherein the housing substantially surrounds the rail;
- a pair of frame brackets connected to said inner shell;
- at least one radiator plate attached between said frame brackets, said at least one radiator plate including a plurality of flame apertures;
- and
- a plurality of burners mounted in said burner apertures to provide a flame inside said housing;
- wherein said flame contacts and heats said radiator plate such that said radiator plate provides thermal energy to the rail;
- and
- wherein said flame traverses said flame apertures of said inner shell and said radiator plate to heat the rail;
- wherein said central processing unit controls the operation of said heating module according to the atmospheric conditions.
The mobile rail heating assembly of 11 wherein the inner shell is Venturi shaped to stratify said flame around the rail.
A mobile rail heating assembly comprising:
- a railway vehicle;
- a control assembly mounted on said railway vehicle;
- a mechanical deployment arm connected to said control assembly and said railway vehicle;
- and
- a heating module connected to said mechanical deployment arm and said control assembly, said heating module including a housing having a first and second end and a heat generator connected to said first end of said housing to generate a heat flow through said housing, wherein said housing further includes an inner shell and an outer shell, said inner shell having a venturi shape to direct said heat flow.
