Doha west power Generation and Water Distillation Station is one of the main base load plants of the country governed by the ministry of electricity and water, government of Kuwait. This power station is situated in Doha, located approx. 15 km to the west of Kuwait city. This power station is composed of eight power generating units of 300 M.W. capacity each and 16 water distillation units of 6/6.2 million imperial gallons per day capacity each. In all, power station is capable of generating 2400 M.W.   (8 x 300 MW) Electric power and producing 110. ( 4 x 6 + 12 x 7.2) million imperial gallon of distilled water per day.       

       The first power generating unit was synchronized on 08.06.82 the last eighth unit was synchronized on 09.07.84. All 8 units had successfully operated for nearly 90000 hours since initial commissioning each generating more than 15500000 MWH without any major constraints. The first distiller started production in july'83 and commissioning of all 16 distillers were completed by January'85. The condition &performance in all 8 power generating units and 16 distillation units are considered excellent even after 16-17 years of operation without any capacity reduction. The turbo-generators also supplied by M/s. MHI/MELOC (Mitsubishi Electric Corporation) of Japan are of double star, Hydrogen cooled type capable of generating 300 MW with a terminal voltage of 21 V. the generated power is pumped into the national grid net-work through 6 over head line feeders after stepping up to a voltage of 275 KV which is another novelty for Kuwait. 300 KV system of our station is connected with the 145 KV system at our end through 3 No. of coupling transformers of (250 MVA each). This 145 KV system is connected the with grid through 3 Nos. of cable feeders to DEPS.

       The boilers supplied by M/s Deutsche Babcock of West Germany are of open-air   installations capable of generating 1.100 T/Hr. of steam at 140 bar & 540 C. These single drum natural circulation, pressurized furnace and RH type boilers could be fired with natural gas, gas oil, crude oil or heavy fuel with mixed firing option. The steam turbines are supplied M/s Mitsubishi Heavy Industries of Japan is a tandem compound, condensing type turbine working on Reheat/Regenerative cycle.

       Operation of the two segments of power generation and water distillation are interlinked in such a way that one boiler would supply  the required steam of one Turbo-Generator and two distillation units at a time. Make-up water requirements of the Boilers would be catered by the station Distillation Plant itself using a De-mineralization Plant of    600 T/Hr. capacity. Fuel gas for DWPS is supplied by M/s K.O.C. through 30 diameter underground pipeline from their high pressure system of natural gas at a pressure of 20 bar. Fuel oil for DWPS is also supplied by M/s KNPC/KPC through underground pipelines (16m diameter) from Mina Al Ahmedi refinery. At our end, the oil is stored in seven tanks, two for gas oil, three for heavy    fuel oil and two for crude oil.

       Another special feature of the unit is that there would be no wastage of steam during start-up conditions and trip-out conditions even from full load. This is achieved by the provision of two by-pass stations (HP Bypass & LP Bypass).

        The boiler can be operated exclusively to supply process steam to distillers through HP/DP reducing stations without turbine in operation. The condenser is sea-water cooled for the recovery of exhausted steam. Sea water requirements of both the power plant and the distillation plant are met with by the sea water pumping. At the sea water intake, the sea water is properly screened before pumping and dosed with Hypo-chlorite solution. This process, combined with cathodic protection arrangements, ensures the condensers and heat exchanges with the necessary cooling sea water free from any living organism.

        In the Multistage flash evaporators connected with thermal Power Station, the distillate production is very pure which contains practically no carbonate hardness, essential minerals etc. Such distillate, being almost unstable could be aggressive and may lead to corrosion of iron pipes and equipment used in the distribution system (Red water problem). The recarbonation system is intended to increase the carbonate hardness in the potable water ( remineralisation of distillate) thereby minimizing corrosion in the water distribution  system as well as to eliminate the health hazards of drinking pure distillate without adequate minerals and salts.
