D6 is also be known as Residual Fuel Oil and is of high-viscosity. This particular fuel oil requires preheating to 220 – 260 Degrees Fahrenheit. D6 is mostly used for generators.
Russian D6 is a type of residual fuel, mainly used in power plants and larger ships. The fuel requires to be preheated before it can be used. It is not possible to use it in smaller engines or vessels/vehicles where it is not possible to pre-heat it. D6 is its name in the USA. In other parts of the world it has other names.
Recent changes in fuel quality regulation now require further refining of the D6 in order to remove the sulfur, which leads to a higher cost. It cannot be used in small ships or boats or cars. However large ships and power plants can use the residual fuel oil.
D6 Diesel Standards and Classification CCAI and CII are two indexes which describe the ignition quality of residual fuel oil, and CCAI is especially often calculated for marine fuels. Despite this marine fuels are still quoted on the international bunker markets with their maximum viscosity (which is set by the ISO 8217 standard – see below) due to the fact that marine engines are designed to use different viscosities of fuel.
The unit of viscosity used is the Centistoke and the d6 fuel most frequently quoted are listed below in order of cost, the least expensive first :
* IFO 380 – Intermediate d6 fuel oil with a maximum viscosity of 380 Centistokes
* IFO 180 – Intermediate d6 fuel oil with a maximum viscosity of 180 Centistokes
* LS 380 – Low-sulphur (<1.5%) intermediate d6 fuel oil with a maximum viscosity of 380 Centistokes
* LS 180 – Low-sulphur (<1.5%) intermediate d6 fuel oil with a maximum viscosity of 180 Centistokes
* MDO – Marine diesel oil.
* MGO – Marine gasoil.
JP54 is an abbreviation for “Jet Propulsion, A1, Colonial Grade 54″ During the refining process only 15% of the crude oil is made up of JP54 the rest of the grade is used for different types of plastic.
JP54 powers gas turbine aircraft engines. Jet A and A-1 have specifications that can be used in fuel worldwide. Jet B is used in cold weather elements. Commonly a number of different mixtures make up jet fuel and this relates to flash points and how the carbon numbers are distributed.
Actually most jet fuel exported from Russia etc. is “JP54” or “Colonial JP54”. It is similar to “Jet A” except the the Specific Energy is 18.4 mj/kg compared to that of 42.8 mj/kg of “Jet A”.
Also there is a slight difference in additives. The jet fuels come in a number of flavors. There is a 100+ page handbook needed to specify them all. However, all the jet fuels relate to additives to A1, which allows the plane not to leave a white tail in the sky showing where a plane has been.
Jet fuel is kerosene, and not a distillate like Gasoil/ Diesel. In the refinery, it separates above gasolines and parafins.
So, no airline will ever purchase “JP54”, there is no trading desk that will trade JP54 and you will find no oil company that sells “JP54”. They will sell Aviation fuel A1 enhanced to a variety of specifications, most usual, the Colonial Grade 54. There is no ticker on the commodity exchanges for “JP54” to allow you to see the market value of the product.
There is no special temperature considerations to consider. Remember that at 40,000 feet it is -46 Centigrade more or less regardless of where you are and the season. The only problem related to temperature is when you fill in a wet, hot climate, the air you take along in the same tanks contains a lot of water that condenses and forms spiking ice crystals that will destroy the jet turbine. The airlines will fix this with additives, usually fatty acids.
Military grade jet fuel is produced by the refineries and delivered directly since they will require special additives.
Mazut is a heavy, low quality fuel oil, used in generating plants and similar applications. In the United States and Western Europe, mazut is blended or broken down, with the end product being diesel.
Mazut may be used for heating houses in the former USSR and in countries of the Far East that do not have the facilities to blend or break it down into more conventional petro-chemicals. In the West, furnaces that burn mazut are commonly called "waste oil" heaters or "waste oil" furnaces.
Mazut-100 is a fuel oil that is manufactured to GOST specifications, for example GOST 10585-75 (not active), GOST 10585-99 Oil fuel. Mazut. Specifications (active, last modified 07.01.2010). Mazut is almost exclusively manufactured in the Russian Federation, Kazakhstan, Azerbaijan, and Turkmenistan.
This product is typically used for larger boilers in producing steam since the energy value is high. The most important factor when grading this fuel is the sulfur content, which can mostly be affected by the source feedstock. For shipment purposes, this product is considered a ”dirty oil” product, and because viscosity drastically affect whether it is able to be pumped, shipping has unique requirements.
Mazut is much like Number 6 Oil (Bunker C), and is part of the products left over after gasoline and lighter components are evaporated from the crude oil.
The main difference between the different types of Mazut-100 is the content of sulphur. The grades are represented by these sulfuric levels:
”Very Low Sulphur” is mazut with a sulphur content of 0.5%
”Low Sulphur” is a mazut with a sulphur content of 0.5-1.0%
”Normal Sulphur” is a mazut with a sulphur content of 1.0-2.0%
”High Sulphur” is a mazut with a sulphur content of 2.0-3.5%
