What else can I help you with?
Where is the dollar plate on a heat exchanger?
It's the flat, flanged cover on the front (and sometimes the rear) of a shell & tube heat exchanger.
What is a shell and tube condenser?
A heat exchanger with straight tubes in a shell that can normally be mechanically cleaned
What is the assumption to design heat exchanger?
The assumption to design heat exchanger is that it must be a shell and tube device. This device must allow the transfer of heat from one fluid to another without mixing the two fluids.
Hydrotesting procedure of Shell and Tube heat exchanger?
The hydro-testing procedure of a shell and tube heat exchanger requires you to fill the shell and tubing with water that had a color dye added to it. Then, raise the internal pressure by 1.5 times the operating pressure suggested by the manufacturer. If there are any cracks in the vessel, the water will be forced out through the cracks.
Function of heat exchanger?
Heat Exchanger - Use And Purpose A heat exchanger is significant in the process of transferring heat from one chamber to another or from one industrial process to a secondary process. Most heating units for home heating include a heat exchanger that involves the transfer of fuel, i.e., oil, coal or natural gas, into heat for circulation and temperature control. Thus, most furnaces and boilers include a heat exchanger as part of the heating system. Heat Exchanger - In Industrial Processes A heat exchanger in an industrial process is a multi-chamber vessel designed at specific ranges of temperature, pressure and where applicable, fluid flow conditions. In certain industrial processes, heat exchangers circulate fluids that are flammable, toxic, dangerous and lethal to humans. This is the reason proper maintainence and precautions, such as draining and/or purging must be taken if a heat exchanger unit is opened for any reason. Types of Heat Exchangers There are several types of heat exchangers. Each of these types can be reconfigured according to specifications and use. There are shell type heat exchangers, front end stationary head types and rear end head types. How air or fluid is exchange by rate of flow is also a significant factor in efficiency of a heat exchanger. When purchasing a heat exchanger, to establish standard terminology for heat exchanger prior to an installation, the unit should be accompanied by a heat exchanger nonmenclature. This is basically identification of typical parts, connections and locations found in schematic diagrams for installation. General Parts Of A Heat Exchanger In most cases, a heat exchanger has a head, stationary or shell as well as tubes, stationary tubesheets, channel cover, flanges, impinger plate, support saddle and vent, drain and instrument connections. Manufacturers assign specific serial numbers to each heat exchanger that are unique for identification and replacement purposes. Generally, a furnace or boiler manufacturer provides an operations and maintenance manual that includes the type and serial number of the original heat exchanger. Replacement of a heat exchanger should be done by a professional, licensed HVAC specialist to avoid hazards. Maintaining A Heat Exchanger The heat exchanger unit should be regularly cleaned, calibrated and maintained.
What is the factors that effect on number of tubes in shell and tube heat exchanger?
The factors that are affected by number of tubes in shell and tube heat exchanger is the rate of heat transfer and flow rate.
Where is the dollar plate on a heat exchanger?
It's the flat, flanged cover on the front (and sometimes the rear) of a shell & tube heat exchanger.
How you can increase the retention time in shell and tube heat exchanger?
the most effective way to do so is to reduce the flow of the heat exchanger
Why impingement baffle is introduced at the shell side inlet of a shell and tube heat exchanger?
increase to heat transfer coefficent
How do you passivate heat exchanger tubes and it is advisable.?
To passivate an exchanger gently pat the shell while whispering into a bleeder
What is a shell and tube condenser?
A heat exchanger with straight tubes in a shell that can normally be mechanically cleaned
What is the difference between double pipe heat exchanger and shell and tube heat exchanger?
double pipe heat exchanger is made if two concentric tubes one carrying cold flow and the other one carrying hot flow. but shell and tube hear exchangers are made of a shell like a vessel filled with many thin tubes to transfer heat between fluids. there are more data available at : http://scopewe.com/double-pipe-heat-exchanger-design-part-1/
What are the uses of shell and tube heat exchanger?

Advantage of shell and tube heat exchanger over double pipe heat exchanger?
**** you.......... pls somebody answer Double pipe heat exchanger consists of two concentric pipes of different diameters.One pipe is for hot fluid and another is for cold fluid.Both may have same flow direction(COCURRENT) and opposite direction(COUNTERCURRENT). Shell and tube heat exchanger consists of a shell in which large number of parallel tubes are present.One fluid hot or cold flow in shell and other hot or cold flow in the tubes. Also in case of shell & tube(S&T) the hot fluid will have more turbulence than in double pipe heat exchanger (HE) since there are no of tubes within a shell the area for convective heat transfer is considerably increased. so these are much more preferredTherefore the rate of heat transfer is greater in shell and tube because large surface area and enough contacting time
What has the author Antony Johnson written?
Antony Johnson has written: 'Flow, heat transfer and pressure drop on the shell side of a shell and tube heat exchanger'
