Can a heat exchanger catch fire?

Gas pressure If this pressure is too little, condensation could collect inside the heat exchanger, which can lead to corrosion. However, if pressure is too high, this may lead to extremely high temperatures inside the unit, even forming soot on the walls of a heat exchanger, which can combust.

What are the common failures in heat exchanger?

A large majority of heat exchanger components fail by way of fatigue, creep, corrosion, oxidation, and hydrogen attack. Most common causes of failure include fouling, scaling, salt deposition, weld defects, and vibration.

What causes a heat exchanger to fail?

The most common cause of an overheated heat exchanger is as simple as a dirty air filter. A clogged air filter restricts airflow through the furnace, overheating the heat exchanger, and eventually resulting in stress cracks. An over-sized furnace can also cause overheating and heat exchanger cracks.

Can a cracked heat exchanger cause overheating?

Your furnace might stop working if you’re lucky, but most often, it will keep running even with a crack, allowing carbon monoxide to seep into your house. The only signs that you have a damaged heat exchanger is either no heat during the winter, reoccurring flu-like symptoms, or a beeping carbon monoxide detector.

What is the result to the occupants if a heat exchanger is cracked?

Cracked Heat Exchanger Causes The filter, coils, and blower get clogged, and the air cannot flow as it should. Air is needed to maintain the internal system temperature and absorb excess heat. With the airflow blocked, the internal temperature increases.This overheating can, in turn, cause the heat exchanger to crack
