PURPOSE:To obtain safe heating adapted for energy-economization by constrcting a fuel oil tank of several pipes with fins and passing hot blast outside these pipes with fins for exchanging heat. CONSTITUTION:Hot blast is introduced into a fuel oil tank duct 8 via a duct 11. The fuel oil tank duct 8 contains a fuel oil settling tank and a service tank inside, and the hot blast is returned to a hot-blast generating device through an exhaust duct 13 after heating these tanks. The oil pumped up from the fuel oil tank is thrown into a pipe 1 with fins of the fuel oil settling tank through an inlet pipe 18, and sent to an oil cleaning device through an outlet pipe 19 after being heated and settled. The fuel oil cleaned by the oil cleaning device is thrown into a pipe 3 with fins of the service tank through an inlet pipe 20, heated, and supplied to a main engine through an outlet pipe 21. |
