Thermal power project Muzaffargarh.
Owing to persistent acute shortage of electricity in our country for last many years Federal Government decided to start work with all munitions in construction of power stations, may they be thermal, nuclear or hydroelectric. in this context construction of 3x210 MW Oil Fired, Steam Powered Station at Multan was planned in 1983. A high powered Pakistani Delegation led by Mr. Ghulam Ishaq Khan, the then Finance Minister visited Moscow in December 1983 and signed an agreement for supply, erection and commissioning of this power station.
Frontier Works Organization (FWO) originally raised for the construction of KKH, after completion of this 8th wonder of the world, ventured into other construction fields and contributed in a big way in construction of highways, runways; dams, canals tunnels, communication stations, jetties and other nation building tasks in remote areas of the country. On call from WAPDA in 1987 it decided to diversify its activities towards power generation projects. FWO'S first experience was of Jamshoro Thermal Station Unit-1, of 250 MW capacity, which was awarded to FWO at a cost of Rs. 350 million. Complete civil works of this unit commenced in 1987. A substantial completion was achieved by March 1989. Based on this performance two more projects were awarded to FWO, one at Muzaffargarh and the other of Mangla.
Muzaffargarh project is an oil fired thermal power station, consisting of three units, each unit of 210 MW capacity. Entire civil works of this project are under execution by 492 Efigineer Group of FWO. The important fact about this project is that after KKH, this is the largest project undertaken by FWO, it is a very high intensity, high precision project.
Muzaffargarh Thermal Power Station is located 5 Kms NW of Muzaffargarh city on Myzaffargarh - Kot Adu Road spreading over an area of 1138 Acres out of which 970 Acres is for power station and the rest for the administrative facilities. The power station consists of 3 oil fired steam operated units of 210 MW each with provision of adding another 3 units of same or more capacity. The estimated cost of the projects is Rs. 8568 million with a foreign component of Rs. 3871 millions. The civil work for the power house is estimated to be of Rs. 800 million and is entirely being done by FWO.
Muzaffargarh being in the seismiczone the design of monstrous power house and other buildings is more complex and complicated. The four ties inspections and supervision by WAPDA, NESPAK, TPS and CCE makes it more challenging to keep the quality of work up to its highest level. The interaction of these agencies provides FWO an excellent exposure to the work of international level. The civil work consists of following:-
a) Different type of structures 170 Nos. b) Cable Trenches/ducts/tunnels 45 KM c) Sewerage line 1.5 KM d) Internal Roads 7 KM e) Foundation of different sizes 20 0
Functionally these structures can be divided into following complexes:
a) Fuel Oil Management Complex: The power units are furnace oil fired and with present 3 units there will be a daily requirement of 3500 tonnes of furnace oil and other allied products. For this 3 special railway trains would be required to be unloaded pumped in the storage tanks and further to the power units. This complex is therefore designed to handle 3 trains load of the oil in addition to about 120,000 tonnes of reserves capacity.
b) Main Power House building complex: The complex consists of the boiler area and the main power house. The boilers have massive foundation work on which the boilers are being erected. The main power house is divided into dearator bay, the auxiliary switch gears area and the main hall. The main hall has three high level concrete pedestal of very high quality and strength upon which the main turbine would be fixed. Each foundation carries 220 cubic meter of concrete and approx. 2.3 tonnes of steel and is poured in one go so that there is no construction joint. The dearator bay area consists of rooms for different purpose. The specifications of each room is different from the other keeping in view its use, thus making the construction of coordination work more difficult and complex. The main building housing the three units is 156m x 55M and 34m high. Using a steel structure weighing 4700 tonnes and 1200 cubic meter of brick work 21 000 and cubic meter of concrete.
c. Combined Auxiliary Buildings: These buildings are the nerve centre of entire power station. All the operation of machinery will be controlled through these buildings. The buildings include:
1) Auxiliary Building with
blocks. 2) Auxiliary Boiler 3) Service Block 4) Ignition Gas Cylinder plant 5) Hydrogen, Oxygen and
Receivers. 6) Oxygen, Acetylene
d) Water Treatment Area. Some 16 cusecs of water is required to make up the losses in the process. This area not only handles the in flow of water but also stores 600,000 gallons of water in huge storage tank The water is treated before it is introduced in the system. For this a cholarination plant has been provided. in addition a pump house building, a wall switching chamber and water testing laboratory have been provided in this area.
e) Heat Dissipation Area: To keep the turbine system cool the water will be circulated. The water will be cooled at 6 cooling towers concrete buildings each 5 storey high having 8 fan stacks of 10.4m dia. Each building having an area of 2080 square meter. In addition two additional buildings as circulating pump house building and fire water pump house buildings have been provided.
f) Flue Exhaust Complex: It consists of two huge concrete chimneys each 195m (640 ft) approx a furlong high, with a dia of 21 meter and wall thickness of 500mm at the base and tapering to approx 9 meters with the wall thickness of 350mm at the top. These chimneys have flue ducts rising inside them and burnt gases from the boiler are dissipated up in the air, so as to save the environment from pollution. The two chimneys are the tallest structures in Pakistan. Construction of such tall chimneys is highly technical and specialized job to which only a very few agencies in Pakistan have been exposed to. With the slip forming method the two chimneys have been completed in record time of 84 days and 102 days.
g) Transformer and Switch Yard Complex: The initial generation of power would be on 15KV. This will be stepped upto 220 KV to match the national grid for these transformer bays have been provided where each transformer can be brought on railways track to its position. The RCC foundation, the railway track and the cut off walls have been provided for each transformer. The switch yard area contains 1159 foundations upon which different structures have been fixed.
Progress/schedule of Work
Time allocated for this huge and gigantic project was only two years. The procurement and consumption of millions of tonnes of steel, cement and other accessories was challenging, FWO therefore arranged best possible machinery and deputed the most dedicated soldiers/ staff team of Corps of Engineers for this job not losing even a single day working during scorching summers when temperature rises above 42C and below freezing during winter endeavour is made to complete the project in time.
Socio Economic Effects
a) Attainment of Self-Sufficiency: This power station when completed is expected to share 10 per cent of the total power requirement and help in a big way to overcome the shortage of electricity in the country.
b) Employment Opportunities: in the construction phase, apart from Army Troops 5 major private firms and a number of petty contractors are working in the area. A work force of approximately 10,000 people is employed in the power station area which is mostly local. On completion there will be about 1,000 people directly employed and many more indirectly employed.
c) Transfer of Technology: Construction of this project is providing wonderful experience to the Pakistan Army and the civilian work force. The experience thus gained will facilitate in completion of all future projects Independent of any foreign assistance.
d) Revenue Generation: it has been estimated that with 60 per cent generation WAPDA is expected to generate revenue as follows:-
1) Daily 6.4 million 2) Monthly Rs. 196.00 million 3) Annually Rs. 2355.00 million.
