What is a potential impact on boiler heat output if there is incomplete combustion?

When combustion in a boiler is incomplete, it leads to the inefficient burning of fuel, which directly affects the heat output. Incomplete combustion typically results in an inadequate amount of oxygen being supplied to the fuel, preventing all of it from being converted into usable heat energy. As a consequence, not only is the total heat energy produced lower, but there may also be an increase in byproducts such as carbon monoxide and unburned hydrocarbons, further indicating wasted fuel and energy.

Due to this inefficiency, the boiler's overall capacity to generate heat diminishes, leading to a decrease in the expected output. This is crucial for operators to understand since maintaining proper combustion conditions is essential for optimal boiler performance, safety, and energy efficiency.
