1£®Service Scope
1.1 Design, manufacturing, technical reform and the related system program design proof for condenser and heat exchanger
1.2 Stainless steel pipes or new brass tubes replacing and installation the used brass tubes for the heat exchangers of condenser, LP & HP Heater, cold oil instrument and circulating water instrument
1.3 Anticorrosion, waterproof ,repairing and pipe material whirlpool flaw detection for condenser, pipe-mouth of the heat exchange and tubeplate
1.4 Condenser and heat exchanger installation
1.5 Condenser and heat exchanger technical consultation
2£®The Start Point of Condenser reform
2.1 Improving the safety and reliability of the units
2.2 Improving the economical efficiency
2.3 Improving the whole technical level for the condenser
3£®Program and execution of the condenser reform ( After calculation, the following program can be selected according to the old units actual condition.)
|
Reform
Program |
Enlarging the reform scope gradually |
|
A
Stainless steel pipe replacing copper pipe only, transition piece adding shower system, other parts without changing |
B
After replacing the tubes, division plate adjusting locally |
C
Tubesheet and division plate replacing |
D
Shell improving |
E
Transition piece and hotwell replacing, changing support and the connecting way |
F
Replacing water box |
|
A |
Simplest program, suitable for small unit |
|
|
|
|
|
|
B |
Simple program, frequently used for 100MW or under the capacity small unit condenser; adding medium separate plate for reducing the inner stress |
|
|
|
|
|
C |
Redesigning the tubes( rearranging the circulating water pipes and changing venting pipe system); tubesheet and division plate being manufactured well in our plant; after reforming, the rate of condensate efficiency being clear with good economical result and remarkable energy save. |
|
|
|
|
D |
1£©suitably make the shell body longer to increase the condensate area
2£©most of the parts being manufactured well in our plant in advance
3£©no longer ¡°enlarge the condensate area¡± being the most suitable one |
|
|
|
E |
Under some condition, transition piece and hotwell being replaced; being used when trying to change the support plate and the turbine connection way |
|
|
F |
This program being like newly designing, manufacturing and installing a new set of condenser within a limited space |
