Heat Exchanger for an Oil Storage Tank

摘要

A heating assembly for heating a liquid storage tank includes a heat exchanger tank supported in one wall of the storage tank to extend into the storage tank in contact with liquid stored therein. The heat exchanger tank contains a heat exchanger fluid therein which is heated by a heating apparatus extending through the heat exchanger tank whereby heat is only transferred to the liquid in the storage tank through the heat exchanger fluid. The heating apparatus extending through the heat exchanger tank may be a burner tube or an electrical resistance-type heating element according to different embodiments of the invention.

主权项

1. A heating assembly for heating a liquid storage tank having walls surrounding a hollow interior arranged to contain a liquid therein, the assembly comprising:
a heat exchanger tank including boundary walls containing a heat exchanger fluid therein; a heating apparatus supported within the heat exchanger tank; the heat exchanger tank being arranged to be supported within the liquid storage tank such that heat from the heating apparatus is arranged to be communicated through the heat exchanger fluid and the boundary walls of the heat exchanger tank directly to liquid in the liquid storage tank.
