Replacement of Dryer Steam Radiators for Laundry Industry

In the laundry industry, the Tube and Fin Steam Coil serves as the heart of industrial dryers. It efficiently and reliably generates high-temperature hot air using steam, providing the core assurance for rapid, hygienic, and high-volume drying operations.

Working Principle

Steam Inflow: Saturated steam (typically at pressures between 0.3-0.8 MPa) from boilers or steam mains enters the tubes at one end of the heat exchanger.

Heat Release: As steam flows through the tubes, it releases two major forms of heat:

Sensible Heat: Heat released as the steam cools.

Latent Heat (Major Component): The substantial latent heat of vaporization released when steam condenses into condensate. This constitutes the primary source of drying heat.

Air Heating: Simultaneously, fan-driven humid ambient air is forced over the exterior of the finned tubes.

The cold air contacts the high-temperature fins and tube walls.

Heat transfers from the finned tubes to the air, rapidly elevating its temperature (e.g., from room temperature to 80-120°C).

Condensate Drainage: Steam that has released its heat condenses into high-temperature condensate within the tubes and is drained from the opposite end (or bottom) of the heat exchanger. Typically, this passes through a steam trap, discharging only water without venting steam.

Hot Air Drying: The heated, dry hot air is directed toward the damp laundry inside the drum, absorbing moisture. It then exits as humid hot air or is recycled, completing the drying process.

Application Features in Laundry Industry Drying Equipment

Rapid Heating: Steam's latent heat of vaporization enables swift air heating to high temperatures, achieving accelerated drying.

High-Temperature Drying: Easily delivers hot air exceeding 80°C, ideal for hotels, hospitals, laundries, and other settings requiring efficient, high-temperature sterilization.

Compact Structure, High Efficiency: The finned design significantly increases heat exchange surface area, maximizing thermal efficiency within limited space.

High-Temperature and High-Pressure Resistance: Specifically engineered to withstand steam system pressures and temperatures, ensuring exceptional durability.

Easy Maintenance and Cleaning: Lint and dust may accumulate between fins, requiring periodic cleaning with compressed air or water to maintain heat transfer efficiency. Well-designed units incorporate access ports for maintenance.
