<p>Heat which has penetrated through the steel casing (2) is conducted away by a fluid through a heat exchanger in contact with the tank (1) or the gas oil. Evapn. occurs with the aid of a fluid which is heated by waste heat from e.g. exhaust gases or output air in a heat exchanger, after which the gas is superheated in another heat exchanger with another hotter fluid. The first fluid is used to temper the gas oil in the tank (1) if required.</p> |
