In the context of stationary engineering, what does "combustion" refer to?

Combustion refers specifically to the chemical reaction between fuel and air, where the fuel is oxidized to produce energy in the form of heat and light. This process is fundamental in stationary engineering, as it is essential for operating various systems, such as boilers and engines, that generate power. The energy produced from this reaction is harnessed to do work, such as moving machinery or generating electricity. Understanding combustion is crucial for ensuring efficient operation, proper maintenance, and safety in systems relying on fuel combustion.

In contrast, cooling down equipment relates to temperature management and does not involve a chemical reaction. Recycling steam focuses on energy efficiency and recovery processes rather than the combustion process. Lastly, the buildup of impurities addresses cleanliness and maintenance concerns but is not directly related to the combustion reaction itself.
