A B S T R A C T The apparatus for preheating heavy fuel oil has the task of using heavy fuel oil instead of light fuel oil at boilers (furnaces) and/or diesel motors. It is adaptable to preheating heavy fuel oil at light fuel oil systems especially For boilers (furnaces) and/or diesel motors. With a preheater thermo insulated operated by a thermostat and a pre erected regulating circulating valve fitted to the return pipe connected through the regulating circulating valve at preheater, the apparatus can solve the task. 1. Thus it is possible to obtain a substantial preheating saving and to reduce the weight of preheating installations and respective thermo insulations of the actual installations whose return pipe of burners and/or injection pumps are connected at daily or mixing tanks. S P E C I F I C A T I O N This invention relates to an apparatus for preheating of heavy fuel oil and using as defined in Claim 1 . It is common apparatus and installations which can use heavy 2. fuel oil. For all boilers (furnaces) and diesel motors the return pipe of burners and/or injection pumps are connected at daily tanks or at mixing tanks. This kind of connection becomes unfavorable because a lot of preheating of heavy fuel oil is lost through the walls of the tanks. For this reason it is necessary to be provided an appropriate thermoinsulation and a corresponding pre- heating installation. I have found these disadvantages may be overcome by providing an apparatus to be able to 3. attract the return of heavy fuel oil from burner/injection pump in way to be preheated and to be oriented again toward the burners/injection pumps. In this manner the invention solves the task to use with a small quantity of energy heavy fuel oil instead of light fuel oil at boilers and diesel motors.
