The purpose of a combustion chamber in a boiler is to:

The combustion chamber in a boiler plays a crucial role in enhancing the fuel burning process. This area is specifically designed to create an optimal environment for the combustion of fuel, allowing it to burn efficiently and completely. Effective combustion is key for maximizing energy output and reducing the formation of unburned hydrocarbons and other pollutants.

In a well-designed combustion chamber, the fuel mixes with the air in the right proportions and is subjected to sufficient heat. This ensures that the chemical reactions involved in combustion proceed effectively, resulting in higher temperatures and improved heat transfer to the boiler’s water or steam system. By allowing for controlled burning of fuel, the combustion chamber directly affects the overall efficiency and performance of the boiler.

While there are other important aspects to a boiler's operation, such as heat transfer efficiency, water circulation, and structural integrity, the primary focus of the combustion chamber is indeed on optimizing the fuel-burning process, which is essential for effective heating and steam generation.
