7 3. Gas systems whb Energietechnik I 7 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.

10 whb Energietechnik I 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. Fuel oil pumping station 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.

11 whb Energietechnik I 11 Burner management station that includes oil flow measuring and metering, flow control and safety shutoff in front of the burner. Furthermore purging and atomizing steam and control air solenoid valves are also incorporated. The station is completely factory assembled, wired to a control cabinet and tested.

12 whb Energietechnik I Boiler equipment whb makes engineering and supplies several boiler equipment such as: Reliable igniters and flame detector systems, Gas and oil burners for any capacity, Burner valve trains for burner management including flow control, metering and shut-off valves Soot blowers. 1 Fuel: Flame Monitoring: Flame detectors: Oil, Gas, Coal, Wood Monitoring systems designed to deliver reliable data. Monitoring quality is in no manner affected by varying operation conditions as a basis for safe and reliable plant operation. High quality flame detectors of different types are provided, depending on type of fuel and number of burners installed at the boiler monitored. 3 Gas supply line 2 Gas feed line to Igniters 1 Air feed line to Igniters 5 4

14 whb Energietechnik I 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 NO x 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 Control and shut-off dampers installed on an air duct 2 Forced Drought (FD) radial fan, m 3 /h, 1800/750 kw with silencers at its double inlets 3 Induced Drought (ID) axial fan, m 3 /h, 1500/675 kw 4 Recirculation ID radial fan, m 3 /h, 1100/450 kw

17 7. Water systems 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 m 3 /h water from 12 C down to 6 C.

19 whb Energietechnik I 19 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 m 3 /h plant. Grab cleaners of a Water Intake Plant with a capacity of 5 x m 3 /h Hydraulically actuated valves in the WTP
