Thus, HFO is also commonly referred to as residual fuel oil. The chemical composition of HFO is highly variable due to the fact that HFO is often mixed or blended with cleaner fuels; blending streams can include carbon numbers from C 20 to greater than C 50. HFOs are blended to achieve certain viscosity and flow characteristics for a given use.
ASTM merged this grade into the number 2 specification, and the term has been rarely used since the mid-20th century. [8] Number 4 fuel oil is a commercial heating oil for burner installations not equipped with preheaters. [8] It may be obtained from the heavy gas oil cut. [7] This fuel is sometimes known by the Navy specification of Bunker A.
The plant had an installed capacity of 4,400 MW. Power is generated by three 600 MW units, and two 1,000 MW units. Units 1 to 4 run on fuel oil and crude oil, [4] whereas unit 5 (600 MW) runs on coal. [5] A new 600 MW coal-fired unit, Unit 6, commenced commercial operation in December, 2013. [6]
Working principle of a combined cycle power plant (Legend: 1-Electric generators, 2-Steam turbine, 3-Condenser, 4-Pump, 5-Boiler/heat exchanger, 6-Gas turbine) The efficiency of a heat engine, the fraction of input heat energy that can be converted to useful work, is limited by the temperature difference between the heat entering the engine and ...

The power station is owned and operated by Electro-Maxx Limited, a private energy provider in Uganda, who built the power plant at an estimated cost of US$60 million. [5] The plant uses heavy fuel oil (HFO), a byproduct of petroleum distillation. [ 6 ]
Powerships are barge- or ship-mounted floating power plants, and they can operate on heavy fuel oil (HFO), diesel fuel, and/or natural gas. Karpowership's powerships are available under electricity-generation services contracts, power-rental contracts, energy-conversion works contracts or power-purchase agreements. [2] [3]
The developers will own and operate the plant for 25 years from commissioning. The construction costs for the plant were KSh12 billion (approx. US$120 million). [ 4 ] The two leading owner-developers are: (a) "Burmeister & Wain Scandinavian Contractor A/S" (BWSC) of Demnmark [ 5 ] and (b) "Aldwych International Ltd." (Aldwych) of the United ...
