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 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 you we use log mean temperature difference formula?

The use of the LMTD arises straightforwardly from the analysis of a heat exchanger with constant flow rate and fluid thermal properties. It is a simple method to approximated the temperature diving force in a heat exchanger. The LMTD is a logarithmic average of the temperature difference between the hot and cold streams at each end of the exchanger. The larger the LMTD, the more heat is transferred.

What tester do you use to test an heat exchanger?

There are different types of heat exchangers. To get an answer the type of exchanger and what type of test you want to do should be stated.


Is a heat pump and heat exchanger the same thing?

No they are not. In fact a heat pump contains within it a heat exchanger/coil. A heat pump is reverse refrigeration. A heat exchange, exchanges heart from a heat source to a conditioned space (the area you want heated). While a heat pump uses a heat exchanger to supply heat to the conditioned space. Reverse refrigeration uses the air conditioner in reverse(you know how heat comes if the back of yhe air conditioner, well when it's in reverse that heat is used to heat a home in winter months.


What is different between cooler and heat exchanger?

Both the cooler and heat exchanger perform the same function as they remove heat from the engine. Two popular types of coolers are air-to-air inter-coolers that allow air to flow over fins and air-to-water models. The heat exchanger is often mounted in front of the radiator and uses airflow to reduce water temperature.

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 is heat exchanger duty?

The duty of a heat exchanger can be defined in an easy way as "The amount of heat exchanged from a fluid at a higher temperature to the fluid at lower temperature in unit time by a heat exchanger is called its duty"

When is it necessary to schedule a heat exchanger replacement?

It is necessary to schedule a heat exchanger replacement when the current heat exchanger is damaged, malfunctioning, or no longer efficient in transferring heat effectively. Regular maintenance and inspections can help determine when a replacement is needed.


What is the relationship between the efficiency of a heat exchanger and its surface area?

The efficiency of a heat exchanger is directly proportional to its surface area. This means that a larger surface area allows for more heat transfer, resulting in a more efficient heat exchanger.
