Why Expansion bellows are required in heat exchanger?
expension belows are used for heat exchanger to avoid thermal stress
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.
Heat Exchanger Types and Uses?
heat sink classified according to the shape, the shape is how to dissipate within the selected heat sink that is the main intension here,, k type l type rectangular triangular chassis i know this much u can down load the pdfs for the types how to select the required heat sink 9844354439
Why is there floating head in heat exchanger?

Explain the purpose of the heat exchanger in the nuclear power plant?
The heat exchanger is the device built for efficient heat transfer from one medium to another, whether the media are in direct contact or the media are separated by a solid wall so that they never mix.

What is the purpose of a heat exchanger in a cooling system water?
Similar function to a car radiator or an air conditioning condenser. The heat from the fluid is pressurized to build up heat. As it passes through the heat exchanger, the heat from the heated fluid is exhanged to the ambient air which passes through the cooling fins.
Types of heat exchanger?

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.
Exchanger is not transfer heat why?
Heat exchanger manufacturers is an ISO 9001 certified company located in Coimbatore, Tamilnadu. The company started its functioning 2011 in, with a strong background in heat exchanger manufacturing. Our well-experienced and dedicated employees consistently thrive to serve our customers with the best heat exchanger solution. visit :: heatexchangersmanufacturers.in
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"
Difference between heat exchanger and condenser?
actually there is no difference , infact condenser itself is a heat exchanger
What type of exchanger is used to condense a vapor by cooling it?
A heat exchanger.
What is the difference between a calorifer and a heat exchanger?
Calorifer is a heat exchanger, with a specific of air (or other gas) preheat. Usually is directly in a Duct installed. Heat Exchanger usually is separate unit.
