Combi Boiler: Hybrid Design for Superior Efficiency and Fuel Flexibility
Combi Boiler -Combitherm
Our Combitherm boiler, also known as Combi boiler or Combination boiler, features a unique design that combines elements of both water tube and smoke tube boilers. In this innovative system, some tubes form an enclosed external furnace where water flows, while the remaining tubes are housed within a shell where flue gases pass.
In a combi boiler the furnace, enclosed on five sides by water tubes, acts as a high-temperature zone, facilitating significant radiation heat transfer. Conversely, convection heat transfer occurs within the shell, where water surrounds tubes carrying high-velocity flue gases.
Furthermore, the membrane tube design in Combi boilers minimizes environmental heat loss. These tubes also offer a substantial heat transfer area, enhancing radiation heat transfer. The shell, designed for two passes, increases the residence time of gases while maintaining optimal velocity for efficient convective heat transfer. Both the shell and water wall tubes contribute to large water and steam holding capacities, maximizing operational benefits.

Combi boiler Combitherm related FAQs-
A 3 pass boiler allows flue gases to pass through the boiler shell three times, improving heat transfer and fuel efficiency. This design ensures better combustion, lower fuel consumption, and higher steam output—ideal for industrial applications.
A combination boiler, or combi boiler, is a multi-fuel boiler that uses two different fuels—typically solid fuel and oil or gas—for steam generation. It offers fuel flexibility, higher efficiency, and uninterrupted operation, making it ideal for industries with variable fuel availability.
A combination boiler can run on multiple types of solid fuels such as coal, wood, briquettes, wood chips, and agro-waste. This flexibility allows industries to optimize fuel costs and ensure continuous operation based on fuel availability.
