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 boiler attendants.
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 Stream’s 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.
Combustion Loop :
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 spray.
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.
Thermic Fluid System :
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 is high.
