In the quest for higher thermal efficiency in medium to large capacity solid fuel-fired boilers, Ross Thermals offers a strategic solution: the inclusion of forced draft combustion air pre-heaters. These large tubular heat exchangers efficiently pre-heat combustion air using the hot flue gases from the boiler.

Key Features

1. Forced Draft Combustion Enhancement

The air pre-heater is designed to enhance forced draft combustion by efficiently pre-heating combustion air.

2. Large Tubular Heat Exchangers

Utilizing advanced heat exchange technology, our air pre-heaters consist of large tubular exchangers, maximizing heat transfer efficiency.

3. Standard Accessory

Available as a standard accessory, the air pre-heater must be finalized during the order placement process to ensure seamless integration with the boiler system.

4. Fuel Savings

While additional investment and floor space are required for air pre-heaters, the resultant fuel savings quickly offset the initial costs.

Working Principle

1. Flue Gas Heat Exchange: Hot flue gases from the boiler efficiently transfer heat to the large tubular heat exchangers.
2. Combustion Air Pre-Heating: Combustion air is pre-heated using the recovered heat from the flue gases, optimizing the combustion process.
3. Forced Draft Combustion Enhancement: The pre-heated combustion air significantly enhances forced draft combustion, leading to improved thermal efficiency.

Applications

Air pre-heaters are recommended for medium to large capacity solid fuel-fired boilers seeking enhanced thermal performance.
