    storage tank contamination

    I have heard that biocides can be effective in killing bacteria within the tank, however, the dead cells can no longer remain at the fuel water interface and they begin to build up on the tank bottom causing another separate environment for bacterial growth. This can lead to bacteria that has...

    storage tank contamination

    Kerosene degrades when it is stored in domestic storage tanks for home heating. Are there any grades of kerosene which degrade slower than others? (such as a kerosene with more heavy ends present..etc) I know that water is the main culprit of contamination and removing water is the best...

    "Magic" water descalers?

    Hello, There are a number of reports which have investigated the theory behind magnetism and its decontamination properties. There is no real concrete evidence to prove that it actually works. Many of the companies that sell these products are independent. I have'nt heard of a global market...

    boundary layer degradation

    Hello. I have a liquid flowing through a pipe, which produces laminar flowrate properties. The boundary layer produced by this is considered to be a thin film. The pipe is exposed to high temperatures which degrade the flowing liquid. If the flowrate is reduced, does the boundary layer...

    Carbon deposits on burners

    Does anybody know why kerosene fed vaporising burners choke with carbon deposits? Is the existence of heavy hydrocarbons within the fuel to blame? Is the fuel being exposed to high temperatures which induce carboning before it has time to reach the burner to evaporate? Any views are greatly...
