3. Gas systems

whb designs and manufactures HP and LP Gas

Pressure Reducing and Metering Stations.

The gas is transported normally by means of

pipelines under the pressure of 70 to 80 bar.

The end-user of the gas needs generally a

lower pressure. An HP Reducing Station is

required to reduce the gas pressure coming

by pipeline, for example down to 20 bar for

gas turbine applications. For most of the other

applications, an HP Reducing Station is required

as a first stage pressure reducing station

followed by an LP station to reduce the gas

pressure according to the requirements of the

end-user, mostly down to less than 4 bar.

A typical gas reducing stationis consisting of:

• emergency shut-off device (ESD)

• condensate knock-out drum

• filter station

• flow measuring

• heater

• line safety shut-off valve(s)

• pressure reducing valve

• silencer

• pressure relief valve(s)

• outlet section

4. Fuel oil systems

Fuel oil facilities from pump house till

burners are one of the most important

part of the power stations that use it

as main or spare fuel.

Fuel oil pumps, heaters, filters, flow

control, metering, safety shut-off and

control valves are main equipment that

are subject to engineering and supply

of whb.

whb's innovative design of valve train in

front of the boiler makes it possible to

combine all components into a compact,

factory pre-fabricated and tested station on a

high quality standard, as shown on the

pictures. This makes not only the installation

works easy, but also the operation and

maintenance. Increased safety through

internal interlocks, real quick closing function

(less then 1 sec.) through pneumatically

actuated reliable shut-off valves are other

important benefits of these stations.

6. Air and flue gas equipment

The huge amount of the air to be used for

combustion of fuel shall be supplied to the

furnace and the flue gas shall be exhausted

to the atmosphere by means of big

ventilators shown on the pictures.

For the fresh air supply to the furnace, Forced

Drought fans shall be installed. These fans

are mostly furnished with inlet air

silencers.

Induced Drought fans are used to feed a part

of flue gas into the furnace, for burning

optimization and reducing the NOx emission.

The flue gas shall be sucked from the boiler

and led to the stack by means of Induced

Drought axial fans.

whb makes engineering and supply of all

kind of fans and as well as dampers to

control the airflow and shut-off the air and

flue gas in ducts.

The vibration control systems will be

incorporated into the control system of the

fans supplied by whb.

Waste water

whb Energietechnik I 16

whb Energietechnik I 17

The water to be used to produce steam

must be very clean and demineralized

so that scale forming in pipes and

equipment can be eliminated. Therefore

it must be treated.

whb’s engineering and supply ranges from

turn-key Water Treatment Plants (WTP) to

particular systems of it, such as Reverse

Osmosis Plant shown on the background.

Furthermore, whb supplies all kinds of

water and condensate valves and pumps for

WTP plants and cooling water systems.

For condenser of the plant, if it is cooled by

raw water taken from a river or sea, a

Condenser Ball Cleaning system is needed to

eliminate the fouling and bio fouling of

cooling water pipes in condensers because

of different kinds of particles in cooling

water, such as impurities, salts, corrosion,

macro and micro organisms. whb solves this

by cleaning the tubes periodically by means

of sponge balls that circulates automatically.

Another engineering and supply of whb is

turn-key chiller stations to acclimatize the

operation and control rooms. The chiller

station cools down a rather big amount of

water used in acclimatization of power plants

that locates in high ambient temperature

areas. The biggest Chiller Station whb

engineered and supplied is 5 x 2 GCal

turnkey plant that cools 1800 m3/h water

from 12 °C down to 6 °C.

For the power plants that has an open circuit

cooling system and uses river or sea water, a

Water Intake plant shall be installed. The

plant shall filter the water mechanically to

reduce the maximum size of impurities down

to 1 mm.

For this, differently sized gratings and finally

fine band screens are used in line.

whb’s biggest supply of such Water Intake

Plant was 5 x 42.500 m3/h plant.

8. Steam and condensate systems

whb`s supplies for steam and condensate are:

• Steam Conditioning systems that controls

the pressure and temperature of steam

for several applications, such as; turbine

by-pass, process steam conditioning,

pressure relief, etc.,

• HP an LP By-Pass Station that reduces the

pressure and temperature of the steam

for; cooling of reheater, cooling of final

super heater, pressure control/turbine by-

pass, to build-up controlled pressure in

the boiler, etc.,

• Safety Valves that blow-off

the steam to the

atmosphere in emergency

cases,

• Condenser Protection to

protect the condenser in

case of disturbance,

• Condensate pumps that

delivers the condensate

into the cycle again,

• Injection Valves that are

used for injection of water

into steam for temperature

reducing.

9. Automation

In a power station, there are thousands of

measuring points to be able to control the

temperature, pressure, flow, level, water

quality, pollution of environment, etc. All

these measurements are part of automation

of many functional parts of systems and the

whole station.

Numerous references and its experience

enable whb to make engineering and supply

reliable equipment for controlling of systems

in the form of control desks, cabinets or

panels, any kind of transmitters, analyzers

and recorders, alarm signalling units and

vibration control systems.

As for every plant, a power station also

needs many specific auxiliary equipment

such as Fire Fighting, Emergency Power

Supply, Pressure air Supply, Hydrogen

Production Plant, Closed Circuit TV-System,

Busduct System, etc.

whb has furnished several power stations

with high quality auxiliaries in the past and

is able to supply any auxiliary system trough

its long-term experience in the field.
