Defination of Desuperheater and its Advantages

Defination of Desuperheater and its Advantages Introduction Basic Desuperheater theory includes that the heated steam has very good advantages on the applications, for example, when used inpower stations to drive turbines. For efficient use on heating applications the steam is to be desuperheated compalsary.

Most desuperheater applications decreases the temperature of steam generated by very much temperature boilers to levels required in process operations. The first function of a desuperheater is to lower the temperature of superheated steam .

Operations All desuperheaters carry on the same operation. Water is introduced into the process line and thus comes into direct contact with the superheated steam. Evaporation of the water decreases the steam temperature. The outer steam temperature is manages by the quantity of water that is evaporated. It is preferred to use hot injection water near the saturation temperature of the steam tfor cooled so that it is the latent heat which is extracted to evaporate the injection water. This decreases the time of the suspension of the water particles in the steam so that all the water is evaporated and none falls to the inside walls of the pipe work.

Types of Desuperheater Freon Desuperheater Ammonia Desuperheater http://www.maniks.com/desuperheater.html Advantages Efficient, evaporated cooling water adds to steam load Various types, configurations and sizes No moving parts No special supports No thermal liner is required Installation The Desuperheater Water Heater is being installed before the condenser and the oil separator. The refrigerant travels through the series of tubes in the Desuperheater before entering the condenser.

Normally the Desuperheater Water heater is designed considering the hot water requirement for the processes. When needs of hot water & refrigeration are not simultaneous, a " Recirculation " type system is provided wherein hot water is generated, stored & maintained in an insulated tank. This hot water then can be utilised as and when required.

The Desuperheater water heater can be easily scroll or screw type chillers.

Maniks has a wide range of desuperheaters as they provide precise refrigerant temperature control for various applications in boilers, chemical, oil & gas process plants, etc where the available

refrigerant is at superheated conditions. These desuperheaters have very good performance, good custom design, easy to install and with zero operating cost.

Maniks Desuperheater Water Heater is the ultimate accessory for an AC & R plant that can be used to remove superheat of the refrigerant.

Design Double Walled " Tube in Tube ", vented, counter flow heat exchanger. Vent tube having serrations on inner & outer surfaces to avoid cross contamination of refrigerant and water/ fluid. Each tube has a tube inside that allows water/ fluid to travel in an opposite direction.

Fundamentals In a usual AC & R system, the refrigerant temperature decreases about of 80℃ to 120℃ after compression. The refrigerant is next put to the air or water cooled condenser to condense near about 40℃.

While the condensing of refrigerant in the condenser, the total heat contained in this high Temperature/high pressure gas gets wasted to the atmosphere.

This superheat of the gas which is part of the total heat content of the gas, has a substantial heat potential provided the same is reclaimed efficiently and is optimized for energy saving http://www.maniks.com
