shell is the place where hot utilities comes across meets with the tubes which is cold utilities, in order to transfer heat. the area of the heat being transfer depends on how many/much the area of tubes being exposed to the shell hot utilities. the greater the area of tubes being exposed, more heat being transfer. hence, less energy needed in order to heat a big amount of cold utilities. decreasing of the temperature from hot utilities which pass over the tubes, next will be recycled back with others hot utilities/sources of heat.

Yes
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.

How do you detect a crack heat exchanger in a furnace?
The most comon way to detect a crack in a heat exchanger is with a visual inspection, removal of the burner assembly and the use of a mirror and flash light. Or a smoke bomb test. A special little smoke bomb is placed in the burner area with the burners OFF. The blower is runnig and you light the smoke bomb, the smoke will draft up the flue vent or if a crack or rust hole is present then the smoke will get sucked into the air stream and come out of the duct work. Other than that using a carbon monoxide detector to see what the CO levels of the furnace are and comparing them to the supply air of the furnace to verify that there is no CO present in the air stream. The best and most accurate way is to contact a local Heating and Air Conditioning specialist or your local gas company should come out and perform a CO test on the furnace. Good Luck and God BLess
Why is Heat still coming out of floor-type heater floor furnace for the home?
it will heat as long as the gas is on and your pilot is still lit, you would have to call your gas company to turn it off.
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.
What is a gas furnace heat exchanger?
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. Ron Ferrara- DHR Mechanical Services, Inc.
How do gas furnace burners function to produce heat in a heating system?
Gas furnace burners function by mixing natural gas with air and igniting it to create a controlled flame. This flame heats up a heat exchanger, which then transfers the heat to the air that is circulated throughout the heating system.
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 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 my gas furnace leaking water?
A gas furnace may leak water due to a clogged condensate line, a cracked heat exchanger, or improper installation. It is important to have a professional inspect and repair the issue to prevent further damage and ensure safe operation.

Is there a way to fix water leaking from a gas furnace?
Yes, water leaking from a gas furnace can be fixed by checking for clogged condensate lines, replacing a faulty condensate pump, or repairing a cracked heat exchanger. It is important to address the issue promptly to prevent further damage and ensure the safe operation of the furnace.
Which would cause a gas furnace to produce a large amount of carbon monoxide?
A gas furnace producing a large amount of carbon monoxide could be caused by a faulty heat exchanger, poor ventilation, or a blocked flue. It is important to have a professional inspect and maintain the furnace regularly to prevent carbon monoxide leaks.
What transfers heat from the hot gas to the airstream to heat the structure?
A heat exchanger transfers heat from the hot gas to the airstream by allowing the two to come into close contact without mixing. The heat exchanger helps to efficiently transfer heat energy from one medium to another, heating up the airstream that is used to heat the structure.
