The preferred heat exchange system for chemical process industries

Shell Tube Heat Exchangers is a kind of heat exchanger specifically used in oil refineries and other places in the chemical process industry. It is perfect for high pressure based applications. The reason this heat exchanger is called shell tube because it consists of a shell, which is generally a large pressure vessel with bundle of tubes within it. The principle of mechanism is one fluid running through tube and another fluid flowing over the tubes. This allows heat to be transferred between the two fluids.  These heat exchangers are most widespread used in the process industries. The reason being they provide a large ratio for heat transfer to weight and volume. They can be easily constructed in sizes varying over wide ranges. Moreover, they are ruggedly built which aides them in reciprocating myriad stresses and gnawing strains which exude owing to any chemical process. Their design, expertise and development are available in abundance and this makes shell tube heat exchangers the choice for chemical process industries.

Wood furnace heat exchanger: an effective heating solution

Wood furnace heat exchanger: an effective heating solution

Wood furnace heat exchanger uses wood as primary source of heat. They can be installed outside the house to heat water which is then piped through to a heat exchanger to our homes. These systems could be water to air or water to water heat exchanger systems. These wood furnace heat exchanger systems have thermostats installed with them for controlling the temperature. Separate thermostats can be used if they are being used for different areas. They can be used as water to water heat exchanger in heating of household water, swimming pools, tubs etc. Most of the modern day wood furnaces burn different kinds of woods be it soft or hard. They even have emission controllers for very little ash to reduce cleaning efforts. Moreover, wood furnace heat exchanger systems are a great alternative during power cuts and extreme winters. The burning time of wood furnaces extend from 18 to 24 hours.

Solar heat exchanger

Solar heat exchanger

A solar heat exchanger is an efficient way to transfer heat between two completely different liquids. The liquids can be same or have completely different physical properties. A solar heat exchanger allows the transfer of energy, efficiently without any heat loss. Heat exchangers can be made of steel, bronze, aluminium, copper. In very cold regions, where it is usually put to use, an anti freeze is used to protect the collector from freezing. A heat exchanger uses a fluid that circulates through the solar collector, takes in the heat and flows through a heat exchanger to transfer its heat to water in a storage tank. Once the heating takes place it can spread by any desirable method through the entire house .It can also be used in a radiant space or a pool heating system effectively. This system is highly efficient because there is no input and solar energy is used.
