What can blockage in the chimney or flue passage cause in the boiler room?

  1. Heat loss

  2. Water buildup

  3. Smoke accumulation

  4. Excessive airflow

The correct answer is: Smoke accumulation

Blockage in the chimney or flue passage can lead to smoke accumulation, which poses significant safety hazards in a boiler room. When a flue is obstructed, the combustion gases produced by the boiler cannot vent properly to the outside atmosphere. As a result, these gases, which include harmful substances like carbon monoxide, remain trapped in the boiler room. This accumulation not only creates a dangerous environment for personnel but also can lead to an increase in pressure within the system, potentially resulting in equipment malfunctions or failure. Additionally, the presence of smoke in the area can indicate incomplete combustion and can lead to fire hazards. Recognizing the importance of proper ventilation and flue function is essential for ensuring safety in any boiler operation.
