Boiler industry Superheaters and reheaters small radius heat exchange are good quality
Boiler Reheater Description
1. Superheaters and reheaters in utility boilers increase the temperature of saturated or near-saturated steam in order to increase the thermodynamic efficiency of the power cycle or to provide the desired process conditions.
2. In general terms, they are simple single-phase heat exchangers with steam flowing inside the tubes and flue gas passing outside the tubes, generally in crossflow.
3.The key criteria in the design of these heat exchangers are:
What is use of a reheater in a thermal power plant?
1. High pressure steam is expanded in turbine, moisture content of exhaust steam increases, which creates problem at exit end blades.
2. So reheat type turbine is most commonly used for large capacity turbine using high pressure steam. Steam after expanding at HP Turbine is sent to boiler for further heat addition or reheat.
3. This steam is called as cold reheat. Cold reheat is heated at reheat is then sent to IP/LP Turbine where it expands further.
4. Single and double reheat turbines are commonly used for power generation.
Performance feature
1. The custom of boiler
With a mature technical team, Dehai boiler can be designed according to the smoke and steam parameters provided by users to achieve the best effect.
2. Low resistance
The boiler body adopts the design of uniform flow rate and low flow rate, and the body resistance is less than 900Pa at the design working condition, which is conducive to the combination with other equipment and to reduce the power consumption of the system.
3. long life
It has long service life, simple operation and maintenance, economic safety and reliability. It is fully applicable to float glass furnace production line using heavy oil or natural gas fuel.
4. Reliably Sealing
The light fender all-welded furnace wall structure is adopted, and the connection between the fender and the steel frame is of flexible sealing structure, so as to ensure that the joint between the fender and the steel frame is not diswelded due to thermal expansion during boiler operation.The whole welded sealing structure of the pipe bundle through the wall of the guard plate furnace reduces the air leakage of the boiler.
Differences
| Type | Advantages | Disadvantages | Supporting method |
| Pendant-type | 1.Firm structural support | 1. Flow blockage by condensed steam 2. Needs slow restart to purge the water that accumulates in the bottom. | supported from above |
| Inverted-type | 1.Proper drainage of the condensed steam | 1. Lack the structural rigidity, especially in high speed gas flow | Supported from below |
| Horizontal -type | 1. Proper drainage 2. Good structural rigidity. | 1. They do not view the flam directly so they are mainly from the convective type | Usually supported in the vertical gas ducts parallel to the main furnace. |
