Maniks Desuperheater Definition of Desuperheater Desuperheater is an energy conservation product used to lower down the temperature of a superheated steam in a system where high amount of superheated heat is generated and emitted in the atmosphere

Maniks Desuperheater Superheated Steam/Gas Superheated steam is a very high temperature water vapor generated by further heating the saturated steam. Same procedure is carried out for saturated gases.

Maniks Desuperheater Desuperheating Process Most common way of lowering the temperature of superheated steam or gas is direct addition of water or relational gas. With the help of Desuperheating process the temperature of this superheated steam can be used for some other applications such as 1. sanitary hot water 2. room heating 3. hot water for processes 4. cleaning water

Maniks Desuperheater Disadvantages of Desuperheated Steam Superheated steam has many disadvantages some of them are listed below Many devices have lowered their performance when supplied with the superheated steam for example distillation columns To deal with superheated steam we require very high rated and expensive equipments. The temperature of superheated steam can damage sensitive equipments of the system.

Maniks Desuperheater Desuperheater theory 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. Desuperheater Steam Desuperheater is used to spray water into steam so that water gets mixed with steam resulting in reduction in the temperature of the outlet steam. 1. Integral type- Desuperheater is in-built with actuator so that there is no need to separate spray water valve 2. Non Integral type- Desuperheater nozzle and water valve are separate units

Maniks Desuperheater Working of Maniks Desuperheater 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
