Thermic Fluid Heaters

At high temperature, water and steam requires a corresponding high operating pressure. Establishing this with water and steam can be very controversial and expensive. In thermic fluid heaters a special oil is used instead as the heat carrier, operating at atmospheric pressure up to 300°C. Compared to water and steam, it would require a pressure of 85 bar to obtain this temperature. There are several advantages of using thermic fluid heaters compared to steam boilers.

The most obvious are

• High temperature upto 300^°C at atmospheric pressure
• No equipment for pre-treatment of boiler feed water
• No heat loss due to hot condensate and flash steam
• No risk of corrosion.
• Low maintenance costs.
• Easy to operate ( does not require a steam boiler certified operator).

The Alfa thermic fluid heaters are thermodynamically optimized & are characterized by high efficiency & excellent heat transfer to the thermic fluid. The combustion chambers are generously dimensioned & are sufficiently long. The flame can thus burn fully & the emission values remain very low for all fuel types.

Alfa has the following distinct advantages

• Large heating surface area hence higher efficiency
• Hinged front door for easy cleaning & inspection
• Rugged construction
• Maximum running reliability

Capacities available are from 1,00,000 Kcals/hr to 40,00,000 Kcals/hr. Fuel firing options are light oil, heavy oil, gas or dual fuel. Units are also available in vertical designs.

Solid fuel fired thermic fluid heaters are available in capacities from 1,00,000 Kcals/hr up to 30,00,000 Kcals/hr.

The vertical design with integral furnace assures rated output on any solid fuel like coal, wood & bagasse. The well-planned design of the Delta ensures thermal expansion with low stress.

The basic advantages of the Delta are

• Low operating cost
• Reliable operation
• Safety against low thermic fluid flow
• Precise thermic fluid temperature Control

The expansion chamber cum deaerator tank is designed to ensure long fluid life. The combined tank has a unique design & offers significant protection against oxidation of thermic fluid. Tangential thermic fluid entry in the deaerator tank ensures good deaeration.
