Why is it important to monitor stack temperature during operation?

Monitoring stack temperature during operation is essential primarily to ensure complete combustion of the fuel. When combustion is efficient, it indicates that the fuel is being burned thoroughly, which results in maximum energy extraction from the fuel while minimizing harmful emissions. An optimal stack temperature helps in identifying proper air-to-fuel ratios; if the stack temperature is too low, it may suggest that there’s insufficient oxygen for complete combustion or that excess fuel is being burned. This not only impacts efficiency but also affects the longevity of the heating system and reduces the potential for creating dangerous byproducts such as carbon monoxide.

Maintaining optimal stack temperature can also aid in preventing the formation of soot and other deposits within the combustion chamber and on the heat exchanger surfaces, which can lead to reduced efficiency and increased maintenance needs. Therefore, regular monitoring of stack temperature is a key practice in ensuring that the oil burner operates at peak performance, contributing to both safety and efficiency.
