The heat exchanger is the metal wall or tubing that is heated up when the burners are ignited. The inside of the heat exchanger allows the toxic flue gases produced from the burners to exhaust out through the furnace flue.
The outside of the heat exchanger is where the cold air passes over, becomes warmed, and is blown throughout the ductwork of the home. The heat exchanger is the only wall separating the toxic flue gases from the supply air.
If a crack develops in the heat exchanger, there is a potential for carbon monoxide gas to leak over to the supply side and be blown throughout your rooms. Carbon monoxide gas is odorless. The human senses will not detect its presence.

How hot does a gas fired heat exchanger get?
There are specific values for heat rise across a furnace heat exchanger given in all installation/operation manuals for all furnaces. As long as these limits are adhered to by the installer the heat exchanger will not overheat. I know this does not answer the question but there is no one blanket answer for all furnaces. Basically the more airflow through the furnace, the lower the HX temp and to determine when the airflow is correct a heat rise test is done and the airflow is set to the mid point of that specification.
Why is the boiler water circulating pump required for EGB?
I think because it works more like a heat exchanger taking heat from the exhaust gas, rather than a "standard" boiler with a furnace?An EGB needs a pump to circulate the water through the pipes in the exhaust stack, whereas a furnace-heated boiler can use convection to move the fluid through the system..?Might have something to do with lower temperatures in an EGB?
Why Expansion bellows are required in heat exchanger?
expension belows are used for heat exchanger to avoid thermal stress
What safety precautions should be taken before cleaning a heat exchanger?
Prior to cleaning a heat exchanger, one should be sure to use hand, body, and eye protection. One should not conduct acid and bleach flushing simultaneously, as this produces a noxious gas which can be lethal if inhaled for an extended period of time.
How does the hmu unit work at refinery?
The HMU unit at refinery works by using the Heat Exchanger Reformer technology to help produce 99.9% pure Hydrogen gas.
A condensing gas furnace uses from a condensing type heat exchanger to increase the furnace efficiency?
Yes
Does a forced air furnace have a heat exchanger?
Yes,It depends if it is gas fired or electric.
Will replacing the heat exchanger prolong the life of your furnace?
The heat exchanger in a furnace is the primary component in a furnace. That said, their are circuit boards, motors and other components that can also fail regardless of the age of the heat exchanger. In my opinion, if you can afford to replace the furnace, you would be much better off. The cost of the heat exchanger with labor is probably not too much less than replacing the entire furnace.
What is a furnace with a horizontal heat exchanger called?
air handler
Is it dangerous to run a gas furnace without the blower motor working?
Yes, you can melt the heat exchanger and start a fire that way
What are the risks of using a gas furnace?
The most important risk in using a gas furnace is carbon monoxide. If the heat exchanger in a gas furnace is damaged, carbon monoxide could leak into the air, causing a health hazard. A carbon monoxide detector and regular inspections would greatly reduce the risks and your worries in using a gas furnace.

How do you plumb a water line to a coal furnace to preheat the water prior to going into a electric hot water heater?
Is the furnace a hydroponic system? If it is you only need to get a heat exchanger (As you don't want the water to your heater flowing through the furnace) and plumb it as another zone in your house. If not you need to find a device for heating water that fits your furnace. and plumb the heat exchanger to that. I believe an heat exchanger is required by code in either case.
Heat exchanger for ammonia absorption refrigeration system?
there are two type of heat exchanger in absorption refrigeration, first is liquid heat exchanger and other is gas heat exchanger.both heat exchanger function is same, to transfer heat (hot medium to cold medium) without violate second newton law of thermodynamics. liquids heat exchanger is between boiler and absorber vessel mean while gas heat exchanger between evaporator and absorber.
What transfers heat from the hot gas to the airstream to heat the structure?
Heat exchanger
What is difference between condenser and heat exchanger?
A heat exchanger is a device that transfers heat from one fluid to the others. A condenser is simply a heat exchanger. It compresses refrigerants into a hot gas to then condense them into a liquid. Majorly condenser is used to cool the required vapor and heat exchanger is used to heat the required liquid.
How do replace a heat exchanger on a furnace?
Your really are better off replacing the whole unit, there was a reason for the heat exchanger to have cracked or malfunction, ether for age or or a mechanical anomaly , you may have not addressed, as of yet.
