One of the perfect conditions for fuel combustion is the presence of good heating and mixing between fuel and air as well as the corresponding heat in the Calderas. The purpose of heating on fuel is:
1. In order for the oil to be diluted so that it is easily separated or cleaned of impurities and achieves a perfect absorption viscosity.
2. With temperatures as high as possible the oil can be easily pumped up to the combustion due to the already low viscosity the oil dissipation will run smoothly and immediately can be burned.
The heating is carried out until it reaches a temperature of about 10 ° C below the flash point and its viscosity is approximately 2 ° Engler. If the heating goes beyond the flash point, there will be a difficulty during the trip to the combustion due to high temperatures resulting in a deposition on the pipe which will be attached to the pipe thus reducing the pipeline.
The fuel ignition
Fuel oil essentially contains chemical elements of carbon (C), hydrogen (H) and little sulfur (S). Each of these elements in the combustion process with an element of oxygen (O2) from the air will generate heat.
From the above reaction was in the combustion process generated H2O water. This is where the difference of opinion on the amount of heat generated. In order to achieve a perfect combustion, the ratio between the amount of oil and air must be good. In order to obtain the perfect combustion is required:
The opaque oil of the kettle should be clean of any dung that is solid or liquid.
The oil must be heated first to a certain temperature.
When leaving the burning mouth the oil has sufficient speed and in an atomized state it can burn and will not hit the burning wall.
Incoming air has sufficient speed and has a way of mixing with fuel well so that every part of the oil burned out. For this purpose, the way of entering the air into the combustion chamber follows the direction of a rotation, and the incoming air must be heated in order to facilitate the burning.
