<p>An apparatus for supplying fuel to a combustion device has first and second tanks for storing light and heavy fuel, respectively, a third tank connected to the first and second tanks by first and second conduits, respectively, for supplying light and heavy fuel to the third tank, a third conduit connecting the third tank with the combustion device for supplying fuel from the third tank to the combustion device; a fourth conduit connecting the combustion device with the third tank for returning excess fuel from the combustion device to the third tank; a pump in the third conduit for driving fuel through the third and fourth conduits. The pump has an output flow rate that is greater than the rate of fuel consumption of the combustion device. The apparatus further has a first valve arranged in the first conduit for controlling the fuel flow therethrough; a second valve in the second conduit for controlling the fuel flow therethrough; a viscosity sensor connected to the fourth conduit for sensing the viscosity of the fuel flowing therethrough; and a control arrangement connecting the viscosity sensor with at least one of the valves for changing the ratio of the rates of fuel flowing in the first and second conduits in response to signals from the viscosity sensor for maintaining the viscosity of the fuel in the third tank and in the third conduit at a predetermined value.</p> |
