THERMIC FLUID HEATING SYSTEM

For process heating application, BABA-THERM liquid heater can be substituted against steam or electricity.

Instead of pressurized hot water or steam, the BABA-THERM product uses Thermic fluids for heat transfer.

Simple closed circuit system is used. Temperatures upto 300 C can be obtained with an accuracy of  1%, at a low working pressure of 2.5 kg/cm (approx.).

The BABA-THERM product is designed on the coil type once through, forced circulation principle to use the heat transfer fluids without risk of chemical degradation.

DESIGNED AND CONSTRUCTION

The internal combustion is used to accommodate concentric helical tube machine wound coil, (fabricated out of ERW Boiler tube as per 3059). This coil is placed in a double shell of mid steel construction. This type of  design helps in economizing the space and simultaneously ensures optimum rate of heat release.

Due to elimination of extensive use of refractory, it permits rapid start up and operational and maintenance flexibility.

The complete BABA-THERM product is supplied in a shop assembled and ready to install condition.

Only the chimney, fuel and thermic fluid pipelines have to be connected.

     
COMBUSTION

A fuel atomizing pressure-jet burner fitted with fuel oil nozzle from "MONARCH" (USA) is placed vertically downward for combustion. A dynamically balanced blower fan pushes the combustion air through the annular space between the inner and outer shell, where air is pre-heated for efficient combustion and higher efficiency. The air acts as an effective thermal insulator eliminating the need for  conventional insulation. Near the tip of burner, air is swirled through a stainless steel diffuser plate and mixes with atomized fuel which achieve combustion in the furnace.

     

     
BURNER AND FUEL SYSTEM


From fuel tank the oil goes to a fuel filter then into a fuel pump. Through the fuel pump it is passed into an electrically heated oil pre-heated tank (this is in case of F.O.) and then forced to burner. The thermic fluid heater is supplied with pressure-jet burner of highly compact rugged and simple design. The burner is fully automatic in operation and switches ON and OFF as per the process heat requirements.

     
NO STEAM - NO INDIAN BOILER REGULATIONS


The BABA-THERM product is outside the purview of INDIAN BOILER REGULATIONS since no steam is generated. No statutory inspections are required eliminating the need for a shut-down of the process. There is no need for a separate boiler house or even a qualified attendant.

     
NO CORROSION - NO SCALE FORMATION


The heat transfer fluids used in the BABA-THERM thermic fluid heater are of mineral origin and do not contain any dissolve solids which cause corrosion of lead to scale formation which is prevalent in case of steam boiler...Because of this, thermal efficiency remains uniformly high, and this is sustained over a long period.

     
INSTRUMENTATION, CONTROL AND SAFETIES


BABA-THERM product is a fully automatic thermic fluid heater fitted with safety devices like high fluid temperature switch, pressure switch, low level switch in expansion tank, spring loaded safety valve, high stack temperature switch, flame sensor, low fuel oil temperature switch and circulating  pump motor interlock.

The unattended operation is possible due to efficient design and highly reliable instruments from reputed manufacturers like Landis & Gyr (Germany), Monarch (USA), Danfoss (Denmark), Larsen & Toubrol, NGEF, Crompton, Kirloskar, Salzer, Finolex, Bells, Tata/TI, Indfoss etc.

A dust proof pre wired control panel housing MCBs, overload relay, contactors, safety alarms, temperature controllers and sequence controllers has audio-visual alarms for abnormal working conditions.

     
AFTER SALES SERVICE


Each thermic fluid heater is rigidly tested before delivery and commissioned by our trained engineers. We have efficient and attentive AFTER-SALE-SERVICE network including routine servicing and supply of spare parts.

All our general spares are readily available from the market.
