Residual Fuel

The Bunker is a residual fuel obtained from the distillation and refining of hydrocarbons, generally has a low price for this condition (residual) that is why priority is given to their use in applications where power consumption is important, as applications naval, electricity generation, preheating furnaces in steel billet, etc. It usually contains a significant presence of asphalt, which are indispensable to turn their fragmentation, but depending on the quality of the distillation and manufacture date can be started without carrying out this process, but certainly the important generation of smoke, bound by conditions environment, to make the process previously indicated, this spray is usually accompanied or assisted by fans, which help to better combustion of the Bunker today have made a significant effort to improve the combustion systems in order to improve combustion Bunker, it usually warms up to the product gases thus optimizing combustion, and is common to identify the placement of additives or item ordered magnetic particles for better combustion, however the first thing that must be done in accordance with good engineering practices is to reduce heat loss in volume control, with this first step can reach lower fuel costs in the business, up to 30% in boilers and furnaces that consume Bunker Sometimes we get a “good” combined oil burning internal combustion engines, with diesel 2 which represents an ecological alternative for this type of waste, which are very harmful if the environment especially water runoff. It is especially important to control the viscosity of the Bunker, which should be about 300 SSF at 50 C, and the lack of water, as this in combination with sulfur in the fuel is normally produces the called “cold corrosion” which is nothing else that the formation of acid sulfuric acid and hydrogen sulfide, which runs the metal from the exhaust of the machinery that uses this type of fuel. The calorific value of the Bunker is a direct function of crude oil source but can be set an average of 9500 kcal / kg is usually a common practice a process of filtering particulate matter prior to the use of waste fuels, such filtering aims separate items such as water, vanadium and sodium at temperatures of about 700 C causes hot corrosion by reacting with some system components such as exhaust valves or turbo chargers, silica and aluminum and heavy metals such as Cr, Pb, Mb, Mn, etc. Usually this is achieved through the use of filters and centrifuges to achieve such separation with the help of the power of the same name, evidently also achieves this separation of the water, leaving the rest in a tank but obviously the time of separation is very slow.
