[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0018] Referring to Figure 1The application discloses a long-lasting fire gas supply structure of an incinerator, which comprises an integrated burner controller 1 and an incinerator 2, and a liquefied petroleum gas pipeline 10 and a fuel gas pipeline 20; the burner controller 1 is arranged as a long-lasting fire and is used for igniting a main fire in the incinerator 2; the incinerator 2 is used for mixing and burning fuel gas and liquefied petroleum gas to burn low-acid gas; because the heat value of the acid gas is not enough, the acid gas cannot be used as a single fuel to maintain normal furnace temperature, and therefore the fuel gas and the liquefied petroleum gas are mixed and burned as the main fire; the liquefied petroleum gas pipeline 10 is divided into a long-lasting fire pipeline 11 and a main fire pipeline 12; the long-lasting fire pipeline 11 is connected with the burner controller 1 and is used for supplying the liquefied petroleum gas to the burner controller 1; the main fire pipeline 12 is connected with the incinerator 2 and is used for supplying the liquefied petroleum gas to the incinerator 2; the fuel gas pipeline 20 is connected with the incinerator 2, and a fuel gas branch 21 is arranged between the fuel gas pipeline 20 and the long-lasting fire pipeline 11; through the fuel gas branch 21, the fuel gas can be supplied to the burner controller 1 to realize long-lasting fire supply.

[0019] In order to more clearly understand the implementation of the technical solution, in the prior art, the fuel gas branch 21 is not arranged, and the fuel gas can only be supplied to the incinerator 2 through the fuel gas pipeline 20 as the fuel of the main fire; the long-lasting fire is always supplied by the liquefied petroleum gas in the long-lasting fire pipeline 11 as the fuel. In the technical solution, the liquefied petroleum gas is used as the fuel of the long-lasting fire when the system is started; after the system is started, the synthetic fuel gas can be normally produced; at this time, the long-lasting fire pipeline 11 is cut off, and the fuel gas is used as the fuel of the long-lasting fire, so that the energy-saving and efficiency-increasing purposes of the fuel gas as the long-lasting fire fuel are achieved.

[0020] Specifically, the liquefied petroleum gas pipeline 10, the long-lasting fire pipeline 11, the main fire pipeline 12, the fuel gas pipeline 20 and the fuel gas branch 21 are all provided with valves for controlling the opening and closing of the pipelines; through the valve control, the opening and closing of each pipeline are realized, and the fuel switching is realized.

[0021] More specifically, because the heat value of the liquefied petroleum gas is greater than that of the fuel gas, the long-lasting fire pipeline 11 is provided with a pressure reducing valve 13; the connection position of the fuel gas branch 21 and the long-lasting fire pipeline 11 is located after the pressure reducing valve 13; through the arrangement of the pressure reducing valve 13, the liquefied petroleum gas in the long-lasting fire pipeline 11 can be pressure-reduced and flow-limited, so that the waste of the excessive liquefied petroleum gas supplied when the system is started is avoided.

[0022] Referring to Figure 1 The incinerator 2 is connected with a waste heat boiler 3; the waste heat boiler 3 is used for recycling the heat gas of the incinerator 2 to produce steam, so that the waste of the heat resource is avoided.

[0023] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
