How do you fix a broken heat exchanger?
The best way to repair a cracked heat exchanger is to remove it and put in a new one . This doesn't require replacing other parts of the furnace. However, it's an expensive repair. Often a repair that's too expensive compared to having a new furnace put in.
What is heat exchanger in furnace?
What is a Heat Exchanger? The heat exchanger in a furnace separates the combustion process from your breathing air . It is a combination metal chamber and passageway that starts at the burner assembly and ends approximately where the chimney vent connects to the furnace.
What is boiler grate?
A furnace grate is provided in a steam boiler furnace for supporting the solid fuel in the furnace . Grate is so designed that it can also allow air to admit air in the solid fuel for combustion.
What are the symptoms of a damaged heat exchanger?

How long do furnaces usually last?
THE AVERAGE FURNACE LIFESPAN
A well-maintained furnace can last at least 15 to 20 years , but completing annual maintenance and being diligent with repairs can extend its life even longer.

What is a sealed combustion appliance?
Sealed Combustion Appliances are heating appliances that vent directly to the outdoors . More importantly, they do not require air from the inside of the building like atmospheric combustion appliances.
How do you bleed the lines on a oil furnace?
What color should my oil furnace flame be?
A blue flame signifies a properly-functioning oil or gas furnace ; any other color indicates a problem with the furnace. In addition to producing more soot, incomplete combustion produces more carbon monoxide (CO), which can cause headaches, nausea and even death if inhaled in large quantities.
How do you troubleshoot an oil furnace?
How do you clean a combustion chamber?
What are the effects of the combustion chamber leaks?
The combustion chamber is the core element of the engine and it ought to be perfectly sealed; however, some of the gas leaks toward the crankcase due to imperfect sealing of the rings. This leakage is known as blow-by and affects efficiency, correct lubrication and emissions .
What are the three types of combustion chambers?
Types of Combustion Chamber. There are three main types of combustion chamber in use for gas turbine engines. These are the multiple chamber, the tubo-annular chamber, and the annular chamber .
