The frame 1 is a rectangular structure, and oil supporting feet are arranged at the four corners of the bottom. An oil pump 2 is fixedly connected to the bottom of the frame 1, and two oil pumps 2 are arranged, one of which is used as a spare to improve the stability of the operation of the oil furnace. If one of the oil pumps is damaged, the spare oil pump 2 can also take over the work.

[0023] A heating chamber 9 is provided at the upper part of the frame 1, specifically, a cross bar is fixedly connected to the upper part of the frame 1, and the heating chamber 9 is arranged above the cross bar. A plurality of heating tubes 19 are provided inside the heating chamber 9, and a junction box is provided at one end of the heating tube 19 to supply power to the heating tube 19. The heating tube 19 generates heat when energized, thereby heating the heat in the heating chamber 9.
