Detailed ways

Referring to Fig. 1 and Fig. 2, the utility model heating heat conduction oil boiler includes a boiler body 4, a combustion chamber 3, and the necessary feed port 2 and air door 1 of the combustion chamber. The combustion chamber 3 is located at the bottom of the boiler body 4 , and the periphery of the boiler body 4 is provided with an insulating layer 10 . The combustion chamber 3 and the boiler body 4 are composed of double-layer furnace walls to form a heat-conducting oil tank 5 around the boiler body. The upper part of the heat-conducting oil tank 5 is connected to the preheating heat-conducting oil tank 7 at the chimney mouth 8 of the boiler. The preheating heat-conducting oil tank 7 is provided with an oil return pipe 9. The upper part of the combustion chamber 3 is provided with a connection box 11, and multiple rows of coil pipes 12 are evenly distributed in parallel on the connection box 11, and the number of the coil pipes 12 is three to five layers. The two ends of each coil pipe 12 are respectively connected with the connection box 11 and the heat transfer oil tank 5 , and the oil outlet pipe 6 is arranged at the upper end of the connection box 11 .

When using the utility model, the heat transfer oil pipe is input into the peripheral heat transfer oil tank 5 and the preheating heat transfer oil tank 7 of the boiler through the oil transfer system of the boiler body. Start the burner in combustion chamber 3. The flame of the combustion chamber 3 burns in the inner wall of the peripheral heat transfer oil tank 5 and the outer wall space of the connecting box 11 and each coil pipe 12, so that the heat transfer oil of the boiler body can be heated instantly and rapidly. The heated heat transfer oil is connected to the heat conduction system through the oil outlet pipe 6 and the oil return pipe 9, and can be used for heat exchange in different occasions. In addition to being used for domestic heating, it can also be used for heating and dilution of large oil storage tanks in oil fields, oil selection stations, water injection stations and other oil wells. Especially when used in an oil field, the semi-gas produced in the oil field can be directly used as the fuel of the utility model after being processed by a petroleum semi-gas drying and filtering device, which is very beneficial to energy saving and environmental protection.
