What is the primary effect of soot accumulation in a boiler?

• A. Increases boiler pressure
• B. Enhances heating efficiency
• C. Reduces heating efficiency
• D. Causes boiler leaks

Answer: (C)

Soot accumulation in a boiler primarily leads to a reduction in heating efficiency. This occurs because soot forms a layer of insulation on heat transfer surfaces, such as the boiler tubes. When soot collects, it impedes the transfer of heat from the combustion gases to the water or steam in the boiler. As a result, more fuel must be burned to achieve the desired temperature, leading to increased fuel consumption and operational costs. Moreover, the insulating effect of soot can cause the boiler to operate less effectively, as the heat does not reach the intended surfaces efficiently. This inefficiency can ultimately result in an increase in emissions and decreased overall performance of the boiler system. Thus, understanding the implications of soot build-up is crucial for maintaining optimal boiler operation and efficiency.
