Flowtherm is a fully automatic,
3 pass, oil/gas fired packaged Thermic Fluid Heater
capable of supplying process heat upto 300° C at
near atmospheric pressure. As the same oil is re-circulated
again between source and sink, its thermal efficiency
is as high as 88%. Steam heating has many advantages
and disadvantages, but the following disadvantages predominate
over the advantages.
When temperature required for steam is 150° C,
the corresponding pressure required for steam heating
becomes too high for economical design of process equipment.
For example, at 300° C temperature, pressure requirements
would be approximately 90 kgs./cm2, i.e.
1280 PSI. Such pressure requires costly equipment, boilers
and pipings and other safety provisions including qualified
Steam heating is associated with the problem of corrosion
and scaling. Corrosion eats away equipment and plants,
while scaling reduces equipment life and erodes your
profits by decreasing thermal efficiency.
Maintenance and operation of water treatment plant
is another headache. Thermic Fluid Heating System is
adaptable to precise temperature control.
Warm Streams FLOWTHERM
is outside the purview of the Indian Boiler Regulation
Act, hence NO statutory inspection is required, eliminating
costly annual shutdowns and procedural delays.
Flowtherm is a completely automatic unit where temperature
and combustion are automatically controlled. The burner
is ON-OFF or modulating type with automatic ignition
and photoelectric flame failure sensing device to safeguard
the combustion operation.
All electric and electronic components and its circuits
are housed in a special control panel cabinet mounted
on Flowtherm. The electronic temperature controller
cum indicator is fitted on Flowtherm which indicates,
monitors and controls temperature of the system.
A Differential Pressure Switch is provided to ensure
a positive flow through the heating oil to safeguard
the same against overheating the coil. If there is no
circulation of thermic fluid, it will stop the combustion
and hence protects the heating coil from overheating.
In any heating system, where fuel
is used for generating heat, what matters most is the
combustion efficiency. Our Flowtherm is fitted with
highly efficient, adjustable high pressure solid injection
type burner, operating at 150 PSIG and above. It consists
of self-cleaning on line oil filter, high pressure fuel
pump, blower with adjustable damper, solenoid valve,
vortex chamber, ignition electrodes and spray nozzle.
The specially designed burner head provides high combustion
efficiency by thoroughly mixing atomized fuel oil and
air. The combustion air is pre-heated by waste heat
available from boiler shell which ensures better combustion
and higher thermal efficiency.
|Gas Loop :
The combustion air supplied by
the combustion blower, while passing through the annular
passage formed between the intermediate and the inner
shell recovers heat conducted and radiated form the
inner shell and then heated air passes through the vortex
generator, where it mixes with the atomized fuel oil
A mixture of oil mist and heated air is then ignited
by a high voltage sparking system. Hot gases first descend
through the inner coil, again descend between the inner
and outer coil, again descend in the annular passage
formed between the outer coil and the inner shell and
it is finally exhausted to the atmosphere via chimney.
It consists of heating coils made
up of high temperature IBR approved carbon steel boiler
tubes, dearator tank and expansion tank and insulated
pipe grid which connects various user's equipment.
The Thermic Fluid pump circulates thermic fluid through
the coil, where it receives heat liberated from combustion.
The heated oil passes through user equipment, where
it gives away heat and returns to the thermic fluid
heater via dearator tank, where the air and the vapour
bubbles are removed. As the same oil is being recirculated
again and again thermal efficiency of entire system
