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.

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 long could gas enter a heat exchanger if a pilot light were to go out during burner operation of gas furnace with a thermocouple pilot safety?
If the pilot light goes out during burner operation in a gas furnace with a thermocouple pilot safety, gas could enter the heat exchanger for a short period, typically a few seconds to a minute, depending on the specific design and settings of the furnace. The thermocouple detects the absence of the pilot flame and signals the gas valve to close, shutting off the gas supply. However, if there is a malfunction, a small amount of gas may still escape before the valve closes completely. Safety mechanisms are in place to minimize the risk of gas accumulation and potential hazards.
How long could gas enter a heat exchange if a pilot light were to go out during burner operation of a gas furnace with a Thermopylae pilot safety?
If the pilot light goes out in a gas furnace equipped with a Thermocouple safety system, the gas flow to the burner should stop almost immediately. The Thermocouple detects the absence of the pilot flame and triggers the gas valve to close, preventing gas from entering the heat exchanger. This safety mechanism is designed to minimize the risk of gas buildup and potential hazards. Typically, the response time is very quick, usually within seconds.

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.
How to repair hairline crack on furnace heat exchanger?
Repairing a hairline crack in a furnace heat exchanger is best left to professionals, as it involves safety concerns with gas and combustion. If you suspect a crack, first turn off the furnace and shut off the gas supply. A technician may use a specialized heat exchanger repair kit or replace the unit if the damage is significant. Always consult a licensed HVAC technician for a thorough inspection and proper repair to ensure safe operation.
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.
