What does a reduction in flame temperature affect?

A reduction in flame temperature directly impacts overall furnace performance because it can lead to incomplete combustion. When the flame temperature is lower than optimal, the fuel does not combust fully, resulting in less heat being generated from the combustion process. This reduced efficiency leads to lower heat output, meaning the furnace struggles to maintain the desired temperature in the space being heated.

Additionally, lower flame temperatures can increase the risk of unburned fuel being released, which not only affects the running efficiency of the furnace but also can contribute to the production of harmful emissions, impacting environmental safety. Overall, the performance of the furnace is compromised as it may fail to adequately warm the space, potentially leading to increased energy costs as it runs longer to try and achieve the set temperature.
