In today’s competitive industrial environment, the demand for efficient, compact, and responsive steam generation systems is at an all-time high. For industries seeking quick steam in limited space, coil type boiler – Revosteam are a revolutionary solution. Designed to deliver high performance with low footprint, these boilers are ideal for small to mid-sized industrial operations.
What is a Coil Type Boiler?
A coil type boiler Revosteam – also known as a coil steam boiler or coil type steam boiler – is a modern version of the water tube boiler. In this design, water circulates through a helical coil that is directly heated by combustion gases. This configuration ensures rapid heat transfer and instant steam generation.
Unlike conventional shell-type boilers, coil type steam boilers have a very low water-holding capacity. As a result, they typically fall under the non-IBR category, simplifying installation, licensing, and maintenance requirements. These boilers are perfectly suited for batch-based or intermittent operations.
How Does a Coil Type Boiler Work?
In coil type boilers such as Thermodyne’s Revosteam, the working principle is based on a helical coil housed inside a jacketed mild steel shell. Here’s how it works:
- Air Preheating: Combustion air is forced into the system through a centrifugal blower. The air passes through the shell’s jacket, getting preheated and improving combustion efficiency.
- Burner Fitment: The burner is vertically mounted. The flame travels downward through the coil in the first pass, initiating radiant heat transfer.
- Flue Gas Reversal: The flue gases reverse upward through the same coil zone, forming the second radiant heat pass.
- Third Pass (Convective): After reversal, gases move between the coil and inner shell, achieving high-velocity convective heat transfer.
- Economizer Section: The flue gases then enter a shell-and-tube economizer, mounted on the same skid. Gases flow through tubes while feedwater surrounds them, preheating water before it enters the boiler coil.
- Optimizer: An optimizer regulates feedwater temperature to maintain consistent heat input.
- Thermal Insulation: The entire setup is lined with ceramic blankets, reducing heat loss and ensuring safer external temperatures.
This three-pass design with integrated heat recovery systems results in high thermal efficiency and excellent fuel economy.
