ROTOTHERM is a Solid Fuel Fired Vertical Thermal Oil Heater, With a Evolved Cyclonic Combustor

Cycloidal Air Injection Technology:

ROTOTHERM comes with a Cycloidal Air Injection technology where is injected into combustion zone in a circular motion thus leading to experience extended residence duration and decreased surplus air levels courtesy of heightened turbulence levels.

Cycloidal Air Injection technology promotes complete combustion, reducing fuel consumption and operating costs. Experience unparalleled temperature control and uniform heating across the entire furnace chamber, ensuring consistent product quality and minimizing production variability.

Furnace Construction:
  • Optimized Heat Transfer
  • Circular Chamber Combustor
  • Enhanced Durability
  • Customizable Options
Hybrid Combustor Design

In any combustor, spreading and distribution of fuel is not uniform. Fuel is densely loaded at the centre and spread thinner at the periphery, the temperature distribution is exactly reverse - the walls radiating at the periphery have higher temperatures. Special air distribution is required for effective air utilization which then leads to effective combustion. ROTOTHERM addresses all these aspects by means of a specially designed hybrid grate layout.

A fixed grate at the center of the combustor, which handles the densely spread fuel ensuring proper air ingress and complete combustion, by utilizing primary air from grate bars plus secondary air form the cycloidal air injection.

Sectoral grate bar with tapered pin holes at the peripheral section, which ensures that the precise quantity of required air reaches the periphery of the combustor, without disturbing radiating/peripheral heat zones.

Maximized Heat Transfer

In ROTOTHERM, both inner and other surfaces of the radiant coil contribute to heat transfer unlike conventional thermal oil heaters, where only the inner surface of the radiant coil contributes to heat transfer. Higher capacities of ROTOTHERM have roof coils which provide more heat transfer area and thermic fluid Holdup. Higher radiation surface counters fouling at convective coil and radiation losses are also effectively reduced due to less surface being exposed to air.

Pressurised Air Cleaning

ROTOTHERM uses a soot blowing system to keep the tube Soot Blower. Surface clean using compressed air and Maintain uniform heat Transfer. This reduces Variation in efficiency When compared with The effect of manual Cleaning in Conventional thermal oil heaters.

Key Features:

ROTOTHERM is a thermal oil heater of modular construction and a small footprint, which comes with pre-insulated coil and sleek aesthetics. It has been designed and engineered for a host of benefits that also make it the most cost-effective and efficient thermic fluid heater in its class. It is so quick to install and have up and running, that it could even be compared with many plug and play, oil fired coil type units.

More effective heat transfer area than conventional heaters -

Ensures highly effective response to heat load. Also online soot blower operates when the blower stops, ensuring clean coil surfaces, good coefficient of heat transfer and better Efficiency.

Specially designed air pre-heater -

Incorporates a cross flow design, which makes the direction of flue gas and air flows opposite and perpendicular to each other, thereby guaranteeing maximum heat transfer from flue gas to air.

Overall reduction in height -

Without the hassle & additional expense of raising roof height, it means that there are no hidden costs.
