Heavy Fuel Oil (HFO) is a general term used to describe a range of fuel oils made from the heavier parts of crude oil after the lighter parts are removed to produce petrol, diesel and other light products. The most common technologies used to generate power from HFO are reciprocating engines and gas turbines.
Why HFO is used in power plants?
Power Plants Fuelled by HFO
HFO power plants offer long term reliable operation expectation, long-life expectancy, lower running and maintenance costs, and low noise advantages – necessary elements for an around-the-clock operation.
How is HFO used?
Heavy fuel oils are mainly used as marine fuel, and HFO is the most widely used marine fuel at this time; virtually all medium and low-speed marine diesel engines are designed for heavy fuel oil. But older steam locomotives and oil-fired power plants also generate energy from heavy fuel oils.
What is HFO and LDO?
Light Diesel Oil (LDO) is used for initial start up while heavy fuel oil (HFO) is used for flame stabilization, mill change over and during low load operation of boilers.
What product is HFO?
Heavy Fuel Oil (HFO) is a category of fuel oils of a tar-like consistency. Also known as bunker fuel, or residual fuel oil, HFO is the result or remnant from the distillation and cracking process of petroleum.
How efficient are oil power plants?
Typical thermal efficiency for utility-scale electrical generators is around 37% for coal and oil-fired plants, and 56 – 60% (LEV) for combined-cycle gas-fired plants. Plants designed to achieve peak efficiency while operating at capacity will be less efficient when operating off-design (i.e. temperatures too low.)
Is furnace a oil?
fuel oil, also called furnace oil, fuel consisting mainly of residues from crude-oil distillation. It is used primarily for steam boilers in power plants, aboard ships, and in industrial plants. Commercial fuel oils usually are blended with other petroleum fractions to produce the desired viscosity and flash point.
How is HFO produced?
HFOs are produced from residuals – the “leftovers” from the crude oil refining process (Leffler, 2000). … The residuum from vacuum distillation, often termed flasher bottoms, is the primary feedstock in the current production of modern HFOs.
What HFO means?
The generic term heavy fuel oil (HFO) describes fuels used to generate motion and/or fuels to generate heat that have a particularly high viscosity and density. The resulting blends are also referred to as intermediate fuel oils (IFO) or marine diesel oil. …
Is heavy oil a diesel or petrol?
In vessels, Heavy Fuel Oil has to be mixed with lighter fuels like Diesel, to help it float. Hence the name Heavy Fuel Oil (HFO). The same product is also known by the technical names as Number 6 Fuel Oil (Bunker C) as well as Very Low Sulfur Fuel Oil (VLSFO).
Is LDO flammable?
Import of Hazardous Chemical Rules 1989, the Rules are not applicable for LDO storage though LDO is considered as a flammable liquid.
How do I check my LDO quality?
The most accurate method of assessing the ignition quality of a diesel fuel is by measuring its cetane number in a test engine, the higher the cetane number the higher the ignition quality.
What is flash point of fuel?
The flash point is the lowest temperature at which a volatile substance evaporates to form an ignitable mixture with air in the presence of an igneous source and continues burning after the trigger source is removed.
What are the types of fuel oil?
Fuel oil has many different names but the most commonly used terms are:
- Diesel fuel.
- Furnace oil.
- Home heating oil.
- Industrial heating oil.
- Marine fuel.
What is the API gravity of heavy oil?
Light oil is characterized by an API gravity of at least 22°, and extra-heavy oil has an API gravity of less than 10°.
Is diesel a heavy oil?
As a product of the distillation process, diesel is at the middle point when it comes to weight. It comes with the appearance of oil but it’s heavier than gasoline. Compared to gasoline, diesel is less difficult to make in terms of refining.
