What is an effect of poor combustion efficiency in a boiler?

Poor combustion efficiency in a boiler leads to higher fuel consumption because not all of the fuel is being effectively converted into useful energy. When combustion is inefficient, more fuel must be burned to achieve the same amount of heat output, which can significantly increase operational costs and resource use.

Additionally, inefficient combustion can result in unburned fuel and the production of harmful emissions, which can complicate emissions control and regulatory compliance. This inefficiency not only affects fuel costs but can also lead to increased maintenance and repair costs over time, as soot and other byproducts accumulate within the combustion system.

In contrast, options related to increased safety standards, better thermal conductivity, and reduced wear on components do not directly correlate with poor combustion efficiency. In fact, poor combustion can often lead to increased risks and operational problems, making those choices less relevant in this context.
