1 and 2, a containerized combustion apparatus 10 is illustrated that primarily includes a frame 12, a venturi burner array 14, and a shield 16.

The frame 12 has a rectangular parallelepiped shape and has a bottom frame portion 18 and four side frame portions 20 extending vertically upward from the bottom frame portion 18.

A venturi burner array 14 is provided at the bottom of the frame 12. In the illustrated embodiment, the venturi burner array 14 is supported on the bottom frame portion 18 of the frame 12 for burning input fuel gas (e.g., venting natural gas). The combustor array 14 includes a plurality of parallel, spaced-apart linear intake manifolds 22. In the illustrated embodiment, seven linear intake manifolds 22 are provided, but in other embodiments the number of linear intake manifolds 22 can be adjusted as needed. These linear intake manifolds 22 are connected to an intake manifold (not shown) such that the gas of the intake manifold can be distributed to each of the linear intake manifolds 22 via a regulating valve or switch. A plurality of spaced venturi burners 24 are mounted on each of the linear intake manifolds 22.

A shield 16 surrounds the venturi burner array 14 to form a flame cavity. The shield 16 is supported on the radially inner side of the side frame portion 20 of the frame 12. Here, the radial direction refers to a direction perpendicular to the vertical center line of the shield. The flame formed by the combustion of the array of burners 14 is blocked by the shield 16 to reduce thermal radiation and light pollution to the surroundings.

In order to introduce more air to participate in the combustion, in the illustrated embodiment, a plurality of support legs 26 are provided below the bottom frame portion 18 of the frame 12 to increase the space below the venturi burner array 14. In the embodiment shown, there are six support legs. In other embodiments, the number of support legs can be adjusted depending on the size of the containerized combustion apparatus. In order to make the transportation process easier, in the present embodiment, the support legs 26 are contractible. For example, the frame 12 includes a plurality of uprights 28 that are configured to be hollow for receiving the support legs 26 during transport. Thus, in the illustrated embodiment, there are also six hollow uprights 28.

To further shield the flame formed by the combustion of the combustor array 14, the illustrated embodiment also includes a plurality of movable shields 30 disposed above the side frame portion 20 of the frame 12. These movable shields 30 can be moved to a vertical position as shown in Figure 1 to collectively form an elevated protective layer to further reduce thermal radiation and light pollution. Each movable fender 30 is moveable between the vertical position and a transport position (Fig. 3) to reduce the size during transport. In the illustrated embodiment, all of the movable fenders 30 are hinged to the upper edge of the corresponding side frame portion 20 of the frame 12 by hinges 32. Thus, the activity of all movable fenders 30 between the upright position and the transport position is a flip motion. It should be understood that other suitable modes of activity, such as up and down translation, may also be employed for the purpose of reducing the size. Alternatively, a portion of the movable shield 30 may be folded, while the other movable shield 30 may be in another manner of movement.

3 is a schematic view showing the container type combustion apparatus 10 in a transport state. In the transport state, the support legs 26 are retracted into the corresponding hollow uprights 28 and the movable shield 30 is folded into the transport position.
