Oil Boiler Low Point Of Fluidez

Preventing Fires in Thermal Oil Heat-Transfer Systems | …

1/7/2001 · Jul 01, 2001. The chemical processing industry has used heat-transfer fluids for more than eight decades. Because thermal fluid heating systems include fuel, air and an ignition source, the risk of fire always is present. However, plants can minimize the risk of fire by strictly observing proper installation, maintenance and operating procedures.

Flash Point Temperature - an overview | ScienceDirect …

The flash point is the lowest temperature at which vapours arises from oil ignites. It indicates the maximum temperature at which a fuel can be stored without serious hazard. If the flash point of a petroleum product does not meet the required specifications, it can be adjusted by blending this product with other fractions.
