The general diesel engine generator set can burn mixed oil, and the viscosity of mixed oil is above 1000 seconds. The inferior heavy oil and residual oil are heated to ensure that the viscosity value of fuel oil before entering the high-pressure oil pump of the diesel engine is less than 65 seconds. The inferior heavy oil with a viscosity value of 3000 seconds needs to be heated to 130 DEG C, and the inferior heavy oil or residual oil with a viscosity value of 6000 seconds needs to be heated to 140 DEG C. At this time, the heavy oil heater needs to be used, and the heavy oil will expand and spray out after being heated.

[0006] Further, the middle part of the buffer tank body is hollow and communicates with the oil inlet end and the oil outlet end respectively.

[0007] Further, the buffer tank body is a cylindrical body.

[0008] Further, the buffer tank body is a cylindrical body with a radius of 75 CM and a height of 450 CM.

[0009] Further, the oil inlet end and the oil outlet end are both cylindrical, and the radius of the oil inlet end is greater than that of the oil outlet end.

[0010] Compared with the prior art, the expander suitable for the heavy oil heater has the following beneficial effects:

[0011] The utility model discloses a kind of expansion machines suitable for heavy oil heater, buffer tank is arranged in expansion machine to buffer heavy oil after heating, heavy oil is entered into buffer tank by oil inlet end after heating by heater, since the radius of oil inlet end is less than the radius of buffer tank, so the pressure of heavy oil after heating can be buffered in buffer tank and then output from oil outlet end.

[0016] In the description of the utility model, it needs to be understood that the orientation or position relation indicated by terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "middle", "inner" and the like is based on the orientation or position relation shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and is not intended to indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features limited by "first", "second" and the like can explicitly or implicitly include one or more of the features. In the description of the utility model, it needs to be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be directly connected, or indirectly connected through intermediate medium; it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood through specific circumstances.

[0017] The embodiments of the utility model will be described below in combination with the drawings and related examples, and the embodiments of the utility model are not limited to the following examples, and the utility model relates to related necessary components in the technical field, which should be regarded as known technology in the technical field, and can be known and mastered by the person skilled in the art.
