Thermic Fluid System
Product Description
Liquid/Gas Fuel Fired:
LGF:
- This is fully automatic horizontal / Vertical coil type 3-pass wet back oil/gas fired, forced draft system.
- It incorporates an integral combustion chamber arranged as a nest of concentric helical tube coil fabricated out of seamless/high heat resistant ERW boiler tubes recommended for high temperature application.
- The concentric coils are placed within a shell fabricated out of Mild Steel.
- The wet back jacket and concentric coil allows three flues passes to ensure low heat release and maximum heat transfer. The design warrants little amount of refractory work on the hinged door to keep thermal inertia low.
- The 3-pass wet back design ensures maximum absorption of heat and flue gas temperature at less than 300°C in a standard heater.
IMPORTED BURNER:
- The heater is equipped with a fully ultimate pressure atomizing type 2-stage, 3-stage or modulating oil/gas burner.
- The Burner is a mono-block construction and can be hinged to left or right.
- It simplifies the work of combustions head diffuser, nozzles and ignition electrodes. Preheated version burners are used for heavy oil firing which are equipped with electric or media oil pre-heaters which are heated nozzle heads and oil line systems.
- This ensures availability of evenly heated oil for flame establishment.
- The nozzle recirculation and positive shut off at the nozzle tip ensures trouble free operation even if temperature drops to below 0°C.
HOT AIR VERSION UNIT:
- Unit offering 92 ± 2% efficiency is incorporated with preheated version of burners developed for special industrial and commercial application in certain industrial processes (i.e. thermic fluid heating).
- Very high rate of flue gas temperature occurs due to the high heat transfer media temperature.
- Tremendous amount of energy can be retrieved by installing heat exchanger (air pre-heater) in the flue gas path which otherwise is lost through stack.
- In the process of cross-mixing, the hot flue gas and the primary combustion air in the heat recovery device (APH), the primary air recovers the excess heat from flue gas and goes to burner block and thus the temperature of flue gas exhaust will not be more than 170° to190° C. This technology application result in
efficiency increase up to 3 to 5%.
- High efficiency 87 ± 2% on NCV of fuel on LGF model.
- 300° C temperature near about atmospheric pressure.
- No corrosion or scale formation.
- It’s a fully automatic operation.
- Adjustable temperature at heater outlet up 300°C with ± 1% accuracy.
- High efficiency level.
- No explosion hazards.
- Exempt from Indian Boiler regulation Act.
- Rapid heating time.
- Thermic fluid can be used till years.

Solid Fuel Fired:
SFH:
- In external furnace, fuel is burned. External firing arrangement eliminates the possible damage to the thermic fluid heater coil.
- Heater Assembly consists of a nest of concentric helical tube coils placed within a sturdy MS shell.
- After each path of flue gas, centrifugal fly ash setting chambers are provide by which fly ash is collected thus preventing soot deposition on heat transfer surface of the heater.
- Combustion chamber being external ensures longer life to heater coil thermic fluid.
- During power failure, no radiation energy is transferred to heater coil and hence ensures complete safety.
- For protection against power failure, specially designed flue by pass system is provided.
- Designed for efficient combustion of low grade fuel.
- Efficiency – 76± 2 % on GCV
- Capacity- 400,000 Kcal/hr to 3,000,000 Kcal/hr
- Temperature – Up to 300° C at atmospheric pressure & at high temperature.

VTL 4 - Pass:
SALIENT FEATURES:
The vertical four pass thermic fluid heater is suited for various industries across India and abroad in this rapidly changing and undependable energy situations. Alfa Entech’s generous design of vertical heaters coupled with integral furnace gives you an assurance of the rated output on any solid fuels like Coal, Wood, Lignite, Husk, Bagasse, Pet Coke, Saw dust etc without compromising on performance.
Alfa Entech can deliver sustainable solution to meet your process requirement and thus improve process consistency and reduce downtime leading to further increase in profitability.
Fluidized Bed Combustion:
Fluidized Bed Combustion Technology is best suited for some of the fuels like low grade coal, paddy husk, agro waste, etc. with high ash content.
FBC Technology ensures:
- Homogeneous mixing of fuel ensuring efficient combustion due to high turbulence in bed
- Automatic operation for consistent performance, hence less dependency on labours during continuous operation
- Efficient Combustion of low grade fuels.
