Presentation Description

A desuperheater is known as a secondary heat exchanger device that transfers heat efficiently from the earth in the winter season and from your house in the summer, into your domestic hot water tank. Desuperheaters are crucial components used in the thermal management of heat from power generation sources to industrial uses in Refrigeration and Air Conditioning. When gas is used for heating or other heat transfer or in industrial processes, it is most efficient when saturated. It is a device that lowers the temperature of superheated gas so that it can be used efficiently for heating or for other industrial use. This gas temperature minimization is also called as attemperation, is performed by the desuperheater water heater (a device that injects a prescribed amount of water into a gas flow stream). The general purpose, of this device is to provide effective and continuous heat transfer between gas and water. And a highly effective desuperheater application and design ensures that costly problems to be avoided, including general wear of downstream piping and equipment, long startup and shutdown times, and reduced process efficiency.

About Maniks desuperheater : Maniks are having comprehensive range of desuperheater supply since last three decades. Maniks introduced variety of desuperheaters with precise temperature control for various applications in chemical or oil & gas process plants where the available refrigerant is at superheated conditions. These Desuperheaters have high performance, custom design, easy to install and requires very low maintenance. Maniks provides two types of desuperheaters Freon Desuperheater - SERIES HEF 33- XXX- 22 Ammonia Desuperheater - SERIES HEA 77- XXX- 717 http://www.maniks.com/desuperheater.html Maniks Desuperheater

Theory of Desuperheater : Desuperheater is a device used to cool the steam in a power plant. When steam is used for mechanical power plant such as driving the turbine rotor by expanding across turbine blades, it will be more efficient when the steam is superheated. A desuperheater is a device which lowers the temperature of the superheated steam so that it can be effectively used for heating or other industrial applications. This action is performed by injecting a predetermined amount of water in to the stream of steam flow. http://www.maniks.com/desuperheater.html Maniks Desuperheater

Need of Desuperheater in Refrigeration The basic principle of refrigeration is the evaporator transfers heat into the refrigerant the refrigerant transfer heat to the condenser then the condenser transfers heat to a cooling medium like water or outside air. The ultimate heat energy emitted from the refrigerators is wasted when it is transferred to the outside air this waste of energy is been avoided by using desuperheater . Desuperheater absorbs the energy from condenser to utilize the same for other applications. http://www.maniks.com/desuperheater.html Maniks Desuperheater http://www.maniks.com/desuperheater.html

Working of a Desuperheater Desuperheater brings superheated steam into direct contact with water the steam is cooled through the evaporation it reduces the temperature of the steam. Maniks desuperheater is designed to work in a refrigeration system so it uses ammonia water inside to cool the refrigerant gas. When refrigerant gas in a refrigeration system is compressed in a compressor it passes though a condenser where it gives off heat and changes to a liquid state and then it passes through an expansion valve to an evaporator coil to absorb heat and change the refrigerant back to gaseous state for recompressing in the compressor to complete and the refrigeration cycle. This cycle is performed repeatedly in refrigeration systems. Maniks Desuperheater http://www.maniks.com/desuperheater.html
