Energy Saving Heat Exchanger Steam Reheater For Industrail Plant , Customized
Product Description
Reheat the exhaust steam of the high pressure or medium pressure steam cylinder to the boiler heating surface at specified temperature.Applied subject: electricity;
Boiler reheater is a kind of steam superheater which reheats the low-pressure steam which has been overdone and reaches a certain temperature. The reheater further improves the heat efficiency of power plant circulation and controls the steam temperature of the final stage blade of steam turbine within the allowable range.
Advantages
1. Reduce the humidity of water vapor, which is conducive to the protection of turbine blades
2. The relative and absolute internal efficiency of steam turbine can be improved
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. |
Constructure
Reheater consists of pipe and collector.Steam and smoke flow in the pipe, respectively.The reheater can be divided into convection and radiation according to different heat transfer modes.The convection reheater is arranged in the convection flue.Radiant reheaters are arranged in the furnace.
