DIVERTERS T DUCTS

Flap diverters allow the user

to

control the

flow

of

TEG to

the

HRSG WHRUj

and

to

positively

isolote

the

HRSG WHRUj so that routine maintenance can be carried

out during normal operating periods.

Each unit s custom

designed to suit the exact

operati

onal requirements in accordance

with the relevant specification.

Flap diverters have been developed over a number

of

years using Finite Element

odel

Analysis to ensure that the thermal

and

mechanical

stresses are

evenly

distributed throughout

the

unit.

The some degree of quality engineering has been lied to the tube design,

shafts and actuation systems

The internal insulation minimises external thermal growth frame distortion

and

thermal stresses. The retainer plates

are

allowed

to

expand independently

of

each

other in all directions.

L--\

As

an

alternative

to

a flap diverter

multi ouvr

dampers can

be bui lt into

a

T Duct section and linked

to

provide an effective

inlet / bypass so lution . These can

be

incorporated with a

gu

otine

to

rr

ov id

e a

fully

integrated inlet/bypass/isolation

solution. Sea

air systems

can be added

to any

of our diverters

to provide 100 sealing

efficiency.

STACK

DAMPERS

To

minimise heat loss from the boiler and

to

prevent the ingress of rain water

Damper Technology have a range of stack isolating dampers which are designed

for

use

with

stacks

from 300mm dio

to in

excess

of 7m

diameter.

The stack

isolating damper

can be

of

the

butterRy

,

twin

louvre,

multi louvre

or

twin

Rap

design and can incorporate

an automatic

pressure

relieving

system to

prevent

over

pressurisation

and damage

to

the

turbin

e or

boiler.
