Abstract

An improved fuel heating system particularly adapted for fuel oil combustion machines such as diesel powered motor vehicles and stationary generating plants is disclosed. The appratuses include a fuel processing device which is integral or separate from a fuel tank which warms fuel before it is delivered to the fuel consuming device. The apparatuses further include a mechanism for heating fuel within the fuel tank in order to warm it to a flowable condition so that it can be transmitted to the fuel processor for further heating. Several embodiments are described wherein the fuel processor and main fuel reservoir are within the same vessel and separated only by a fluidtight wall. In another embodiment, a fuel processor unit is physically separated from the fuel tank. Various means are described for communicating heat within the fuel processor to the main fuel reservoir including conduits conducting engine coolant and ror or plate type heat conductors. This invention provides fuel heating systems which are capable of quickly supplying warmed fuel to a fuel oil fired device and further provides such heating in a highly efficient manner.
