For those situations where safety considerations or fuel
availability render the use of propane undesirable for heating
continuous welded rail (CWR), TELEWELD can now provide
an alternative.
The SERIES ID CWR HEATER CAR features clean and
efficient burners using pressure injected, #2 diesel fuel and
blower impelled, combustion air. A short flame projection,
and side shields that confine the heat output close to the
rail, maximize the transfer of heat to the rail while minimiiing
the possibility of igniting ties or other flammable materials
in the road bed.
¢Ã PRODUCTiON CAPACITV:
Using 10 burners, over a rail, production capacity is
indicated by the following data.
Heat Requirement: One (1) B.1.U. to raise temperature
of 10 Ibs. of rail one degree F.
Weight of Rail: 115 to 136 Ibs. per yard plus additional
heating load from the tie plates. Use 50 Ibs. per 11. for this
example.
Travel Rate: From 30 to 15011. per minute. Use 7511.
per minute for this example.
Heating Load: One minute = 75'x50# = 3,750 Ibs. or
375 B.T.U.'s per minute per degree F.

Heat Input Required: To raise the rail temperature 50
degrees F. = 375¡¿50 = 18,750 B.1.U.'s per minute.
Heat Available: If a combustion efficiency of 75% is
assumed, a bank of burners will produce approximately
28,000 B.1.U.'s per minute at a 150 psi fuel pressure.
Note: The actual efficiency of transferring generated
B.1.U.'s into the rail will depend on wind conditions,
ambient temperatures and other factors.
¢Ã FEATURES:
Diesel fuel reservoir, with 300 gallon capacity,
manufactured to ANSl/NFPA specifications 385 and 386.
Operator's platform with gauges and controls arranged
for safe and convenient operation.
Heating assembly consisting of 10 burner units capable
of producing T ,800,000 B.1.U.'s per hour at maximum fuel
pressure of 150 psi.
Individual spark plug igniters in each burner.
Self propelled work speed up to 3 MPH with optional
travel speeds up to 18 MPH.
' Powered by a Diesel engine with separate fuel reservoir.
1 Work and travel lights on both ends of the car.
' An optional, hydraulic rail vibrator to assist physical
expansion of the heated rail.
