Railcar thaw sheds were originally
designed to thaw raw materials from coal to paper pulp. When the railcar
is transported from a variation of cold climates, the problem exists
that a fair percentage of raw materials are frozen to the inside of the
railcar. This can become extremely costly for the company receiving the
material. Raw material can be lost in an improperly thawed railcar that
is still housing a percentage of their purchase. It also poses problems
in manufacturing. Raw material that is still frozen and unclaimed can
cause time and manufacturing delays.
Many railcar thaw sheds still utilize the inefficient gas fired, open
flame heaters that heat from beneath the railcar. This causes several
concerns.
First, an open flame heater can cause damage to the hydraulics of the
railcar that can result in additional damage charges from the railroad.
Second,
these heaters have a perforated emitter that gets clogged & causes
a decrease in Btu output and performance. Third, this type of heater is
no longer manufactured, and parts are becoming increasingly difficult to
locate. Finally, the heaters are a maintenance nightmare & working
on them is incredibly dirty.
A customer in Gary, IN was interested in saving fuel and maintenance
time on their outdated railcar thaw shed. PRP assisted in designing and
providing
the Space-Ray RSTP17 gas fired infrared tube heaters for his railcar
thaw application. The RSTP17, which has aluminized, calorized steel tubing,
is capable of thawing materials in a timely fashion, provides a quick
payback
in fuel cost savings, and is much easier to maintain. The RSTP17 has
the highest ability to provide the heat to thaw a variation of railcar
contents
successfully. The heater is delivered completely assembled and is quite
simple to install & maintain. To safeguard the control boxes from
damage when there is no railcar present, the customer covered the control
boxes
with a material that would not absorb heat.
As shown in the photos, this is a railcar thaw shed that was installed
in Fall 2002. A total of 188 - 250,000 Btu heaters were replaced with 122
Space-Ray RSTP17 (175,000 Btu each) infrared heaters. This proved successful
while using nearly 1/3 less heaters, resulting in much less fuel consumption
and increased performance. This customer is very pleased with their new
railcar thaw shed. They anticipate the new system will pay for itself in
fuel and maintenance savings $$ in less than 1-1/ 2 years of use. If you
