Abstract
Abstract A process for vaporising fuel oil employs a cylindrical porous heating element through which the oil is passed from the axis, radially outwards. The element is of polycrystalline metal whiskers. The oil feed is in excess of that which the element is capable of vaporising, the excess being returned to the oil source, and the vapour being used for combustion.

Claim 4
Dependent Claim
18 words
A process as claimed in claim 2, wherein the body is directly heated by electric current passing therethrough.
Claim 5
Dependent Claim
20 words

Claim 6
Independent Claim
127 words
A device for vaporising fuel oil, comprising a substantially cylindrical porous body of polycrystalline metal whiskers connected with one another metallically at their points of contact, and formed with a central longitudinal duct, means for heating said body, an oil supply pipe communicating with said duct, the oil adapted to pass radially from the duct through the heated body to vaporize the oil, means for supplying more fuel oil to the body than is vaporised, a housing surrounding said body with a space therebetween for receiving the oil vapour, means placing said housing in communication with a mixing chamber for mixing the oil vapour with air for combustion, and a discharge pipe from a low point of the housing for discharging fuel oil that has not evaporated.
