Proper ventilation in boiler rooms is crucial primarily to ensure adequate air supply for combustion. Boilers require a specific amount of air to effectively burn fuel and generate heat. When the combustion process occurs, oxygen from the air combines with the fuel, producing energy while emitting gases as byproducts, such as carbon dioxide and water vapor.

If the boiler room lacks sufficient ventilation, it may lead to a scenario where there is not enough air supplied for efficient combustion. This deficiency can result in incomplete combustion, producing excess carbon monoxide, which is dangerous and poses safety risks. It can also cause operational inefficiencies, such as increased emissions and reduced heat output from the boiler system.

Additionally, a well-ventilated boiler room supports the proper functioning of combustion equipment and helps to maintain boiler efficiency, as the system will be able to draw the correct ratio of air to fuel, leading to more efficient energy production. This is why adequate ventilation plays a critical role in maintaining operational safety and performance in boiler rooms.
