Reheater Coil
1. We have successfully supplied Reheater coils for boilers up to 210MW. Swaging was done for tubes from 63mm OD down to 57mm OD and attachments were made through investment casting.
2. Meeting customer demands, we have manufactured tubular pressure parts from the complete range of tube material including SA192, SA210 Gr. A1, SA213-T11 / T22, SA213-T91, SS-316, SA213 TP347H.
Hot Reheat System
1. Hot reheat steam system has two safety valves, which functions also as pressure controlling device’s. Hot reheat system valves blow first and therefore in some operation situations HP –pressure station valves can be maintain closed.
2. These valves are used for regulating the boiler pressure especially during start ups (or shut down). The start-up steam line is led to atmosphere trough a silencer. The reheat steam enters to reheater IA, which is of similar construction to superheater I and located in the back pass of the boiler after SH II. Reheater IB is after SH I.
3. Reheat steam temperature is maintained at design value typically over load range 60 –100 % of MCR. Compared with feed water spray control by-pass control gives higher plant efficiency. Final reheating takes place in reheater II, which is similar in construction to Intrex superheaters and is located in the return leg. All superheaters and reheaters are fully drainable.
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. |
