DiFFusers / plenums (1)One o the major transition areas between the gas

turbine exhaust and the exhaust system is the diuser

duct or gas turbine exhaust plenum duct section. On

the larger & newer type IGTs the exhaust gas ow is

directed into the exhaust system through a diuser duct

(straight ow) and on some specifc type IGTs through

a gas turbine exhaust plenum duct section changing

direction o ow into a 90 degrees bend.

For both systems Aarding Thermal Acoustics provides

diusers and plenums specifcally engineered to cope

with the strong GT exhaust gas swirl characteristics

as well as the high GT exhaust gas velocities and

temperatures. To accommodate start stop operation

as well as operation at elevated temperatures, Cold

casing designs specifcally engineered or the applicable

operational conditions are the current standard.

GT exhausT DucTs (2)Exhaust ducts are mainly applied as transition between

diuser and diverter systems or between the diverter

system and HRSG (inlet ducts). Main design ocus is

related to the high swirls, exhaust gas velocity and

elevated temperatures.

Aarding Thermal Acoustics designs and provides the

latest cold casing design adapted to todays stringent

operational conditions. Ducts are commonly engineered

including additional eatures such as dedicated

silencer assembly supporting systems Accommodating

high gas ows and start stop operation), turning vanes,

ast opening & closing access doors and compensator

connection anges. In addition, all systems are designed

to meet both thermal (maximum surace temperatures)

and acoustical (noise levels) requirements based on

either local or governmental requirements.

bypass exhausT sysTemsTo realize higher efciency levels gas turbine waste

heat is used to generate process steam or steam

turbine operation. Aarding Thermal Acoustics provides

Bypass Exhaust Systems between gas turbines and

HRSGs. These Bypass systems allow exible operation

o the power island as well as the capability o

starting the gas turbine in rapid starting mode and

allowing the HRSG to gradually come online.

This approach gives oers the exibility o ast power

and increases the lie o an HRSG. In todays business

environment bypass exhaust systems provide a solution

or the option between baseload and peaking/

modulating operation.

exhausT sTacksAdvanced type gas turbine operation requires high

perormance o the insulation systems, silencer assem-

blies and supporting systems o Exhaust stacks. Noise

regulations oten demand complex design silencer

systems and turbine exhaust gas temperatures require

a dedicated thermal design.

Existing and ageing stacks oten show extensive wear

since most older designs have difculty coping with

the current operational strains.

Aarding Thermal Acoustics has developed eective

internal stack insulation systems and can oer a

combination o the most economical and eective

stack system including stack design, support structures

and auxiliaries as well as a silencer system which will

oer both long term operation as well as excellent

mechanical perormance. A complete scope can

be supplied including silencers, stack dampers, FAA

lights, lightning protection and other related require-

ments. Based upon our experience we are able to

inTernal insulaTionCold Casing Design

Aarding Thermal Acoustics has developped an

in-house design o internal insulation systems based

upon the latest operational requirements and newest

materials. In our cold casing design, the insulation

system is ftted to the casing interior using a custom

designed support system. The protective sheeting is

engineered based upon the most economical &

eective distance (insulation thickness) rom the cold

outer casing wall by studs, nuts and washers enabling

ree thermal expansion o the metal sheeting in

relation to the outer casing wall (oating plate

principle).

Aarding Thermal Acoustics design includes:

+ Lower exterior duct/casing temperatures resulting

rom the use o custom designed internal insulation

+ Eliminating or reducing external duct sliding

connections applying cold design

+ Ease o maintenance as a result o sectional design

o internal insulation and optimised feld joint

designs

+ Minimizing external duct movement resulting in

longer duct lie and less strain on exible joints/

bellows

+ Options to include higher temperature operation as

a result o GT upgrade or installation o additional

burner systems

With the experience o more than 750 reerences

worldwide, Aarding Thermal Acoustics has the know

how to execute the complete engineering in-house in

combination with the supply o the complete

insulation package.

boiler inTernalsAarding Thermal Acoustics provides HRSG baes.

These baes are normally located direct within the

ow o hot exhaust gas through the heated suraces o

the HRSG / boiler (harps or modules). These baes

aTmospheric VenT silencersAarding Thermal Acoustics Atmospheric vent silencers

are typically used in conjunction with a relie/saety

valve or a start up valve. Applications are in heat

recovery systems, steam boilers, and at oil/gas/

chemical processing plants. The Aarding Thermal

Acoustics vent silencer eectively eliminates high,

unwanted noise at the source and provides or low

sound level discharge to the atmosphere. This type

o design is a reactive/ absorptive type o silencer.

Aarding Thermal Acoustics vent silencers are custom

designed or each and every application ensuring the

best acoustical perormance and can be designed or

any service condtions or ow rates rom as low as

1,000 lbs/hr to upwards and exceeding 1 million

lbs/hr.

commissioninG silencers For renTalAarding Thermal Acoustics commissioning silencers

are designed or steam systems to vent down during

commssioning allowing the systems to clean and to

get rid o possible remnants & deposits present within

the systems located upstream.

The Aarding Thermal Acoustics commissioning type

silencer is designed to reduce noise pollution caused

by high pressure gasses rapidly venting to the

atmosphere during commissioning. This silencer is

custom designed to vent approximately 1.2 million

lbs/hr o steam (depending on steam pressure/

temperature) and provides 35-40 decibles o noise

reduction. Additional reduction in total noise is

achievable i required with an acoustic splitter

package installed at the outlet o the silencer. This

design with splitter package can provide or over

50 decibles o noise reduction.

The silencers can be rented or use during commis-

sioning o new systems or ater extensive maintenance

activities. The silencer is skidded or shipment and

installation. The unit can be easily installed and

connects the supported and restrained temp

in-line DiFFusersThe Aarding In-Line Diuser assembly is designed to

reduce the noise typically associated with pressure

reducing valve applications. These in-line diusers are

o the diusing type designed or the reduction o

excessive noise rom pressure reduction systems or

steam, gas, air, or other mixed gas type services and

are especially eective when used in combination

with a valve to achieve and/or share the total

pressure drop required by the system.

The In-Line diusers provide several unctions:

Dispersing high pressure reductions typically seen

at pressure reducing valves and regulators, and air

cooled condensers down to vacuum conditions.

Dissipating high energy noise and reshaping the

requency spectrum, shiting the peak requency to

a higher octave band.
