Medium temperature coal asphalt manufacturer Mengbei
There are significant differences between coal pitch and petroleum pitch in terms of combustion characteristics.
First of all, the two produce different flames and smoke during the combustion process. Coal pitch produces bright flames, black smoke and abundant heat during combustion, while emitting a strong tar smell; On the other hand, the flame produced by the combustion of petroleum asphalt is blue, and the smoke is less, and the smell is milder. This is mainly because coal pitch contains more carbon and hydrogen elements, while petroleum asphalt mainly contains carbon elements, and the residues after combustion are also different. Petroleum asphalt mainly retains organic matter, such as carbon black and unburned hydrocarbons, after combustion, while the residues after combustion of coal asphalt are mostly ash and unburned coal asphalt residues.
In addition, the composition of coal pitch and petroleum is also different. Coal pitch contains more minerals and impurities, which may affect the combustion characteristics of the flame when burned. However, the composition of petroleum bitumen is relatively simple, and its combustion characteristics are relatively stable.
In general, there are significant differences in the combustion characteristics of coal pitch and petroleum pitch. It is mainly manifested in the combustion process, flame color, smoke, smell and residue. These differences are mainly due to the difference in the chemical composition and physical properties of the two types of asphalt.
