In the working state, biomass enters through the feed port and is continuously heated through each straight section of the furnace body to generate syngas. As long as the biomass raw materials are continuously supplied, the continuous production of syngas can be guaranteed, so that the syngas generation step can be matched with the subsequent processes.

[0010] According to one embodiment of the present invention, the continuous biomass reactor further includes a fuel supply module, which is connected to a flame-type heater to supply fuel to it.

[0011] Preferably, the fuel supply module includes a fuel tank and a fuel delivery pipe, wherein the fuel tank is connected to a flame-type heater via the fuel delivery pipe.

[0021] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0022] Example 1:

[0023] A continuous biomass reactor, such as Figure 1 It includes a biomass conveying pipe 1, a furnace body 2, and a flame-type heater 3.

[0024] The biomass conveying pipe 1 is arranged in a tortuous manner. In this embodiment, the biomass conveying pipe 1 adopts a square wave tortuous structure, which can also be understood as a pipe body composed of several U-shaped structures.

[0025] The biomass conveying pipe 1 has an inlet 11 and an outlet 12 at both ends. The inlet 11 is for the biomass powder to enter, and the outlet 12 is for the synthesis gas generated by the biomass to be discharged. It is also provided with several straight sections 13 and bent sections 14. Adjacent straight sections 13 are connected by bent sections 14. The furnace body 2 is located at each straight section 13. The flame-type heater 3 is installed on the furnace body 2. Several flame-type heaters 3 are provided on each furnace body 2. Several flame-type heaters 3 are arranged around the biomass conveying pipe 1. Generally, three groups are arranged to achieve the purpose of uniform heating. The furnace body 2 is enclosed to prevent the flame of the flame-type heater 3 from being exposed, thereby improving the heat utilization efficiency. The furnace body 2 is provided with a heat insulation layer to ensure the maximum utilization of heat. It is also possible to provide a heat insulation layer on the biomass conveying pipe 1.

[0026] Preferably, at least four sets of straight segments 13 are provided to ensure continuous production of syngas.

[0027] like Figure 2 At least some of the bends 14 are provided with slag discharge ports 15. Preferably, the slag discharge ports are provided at the bottom bends 14. Alternatively, slag discharge ports 15 can be provided at all bends 14. The slag discharge ports 15 can be valve bodies or plate structures. After the slag discharge ports 15 are opened, they are used to inspect the pipeline and discharge ash. In this embodiment, at least two sets of slag discharge ports 15 are provided at each bend 14. The two sets of slag discharge ports 15 are respectively provided for the two sets of straight sections 13 connected to the bend 14, which facilitates the slag discharge and maintenance of each set of straight sections 13.

[0028] The continuous biomass reactor also includes a fuel supply module, which is connected to the flame-type heater 3 to supply fuel to it.

[0029] The fuel supply module includes a fuel tank 32 and a fuel delivery pipe 31. The fuel tank 32 is connected to the flame-type heater 3 through the fuel delivery pipe 31.

[0030] The biomass is in powder form, which ensures maximum heating. Moreover, the biomass is transported by gas, which ensures continuous operation. The biomass enters through the feed inlet 11 and is continuously heated sequentially through each straight section 13 of the furnace body 2. In this embodiment, four furnace bodies are used for heating four times, which ensures that the biomass is cracked at high temperature to generate syngas with carbon monoxide, hydrogen, and carbon dioxide as the main components. As long as the biomass raw materials are continuously transported, the continuous production of syngas can be guaranteed, so that the syngas generation step can be matched with the subsequent processes.

[0031] Optionally, the furnace body 2 can be connected to the biomass conveying pipe 1 in a detachable or fixed manner, such as by bolting or welding.

[0032] Example 2:

[0033] Based on Example 1, the continuous biomass reactor also includes a biomass feeding module, which includes a gas source that provides pressurized gas. The gas carries the biomass raw materials through the biomass conveying pipe 1 via the airflow. The gas can be air or an inert gas.

[0034] Optionally, one or more gas sources can be set. When one source is set, it is located at the inlet 11 or before the inlet 11. When several sources are set, they can be set at the bend section 14, facing the next straight section, which is suitable for longer biomass conveying pipes 1.
