This process releases heat energy, which is further used to heat water and evaporate it into high-temperature and high-pressure steam. The steam is then sent to the turbine, and the rotation of the turbine drives the generator to generate electricity, thereby realizing the process of converting the chemical energy of the fuel into electrical energy.

By setting the activated carbon filter plate 6, the gas entering the inner cavity of the square tube 1 is filtered and purified, and dry and pure gas is provided to the boiler, which is convenient for the combustion of dye in the inner cavity of the boiler. By setting the air supply mechanism 7, it is convenient to transport external air into the boiler, which is convenient for the combustion of fuel in the boiler.

[0020] See also Figure 2 The air supply mechanism 7 includes a cross bar 70, and a sleeve plate 71 is sleeved on the surface of the cross bar 70. The top and bottom of the sleeve plate 71 are fixedly connected to the inner wall of the square tube 1. The surface of the cross bar 70 is fixedly connected to a fan blade plate 72. By setting the sleeve plate 71, the cross bar 70 is supported, so that the cross bar 70 can drive the fan blade plate 72 to rotate stably.

[0021] See also Figure 2 A spiral groove 73 is provided on the surface of the cross bar 70, and a moving tube 74 is sleeved on the surface of the cross bar 70. A spring telescopic rod 75 is installed through the bottom of the moving tube 74, and the top of the spring telescopic rod 75 extends to the inner cavity of the spiral groove 73. An electric push rod 76 is fixedly connected to the left side of the spring telescopic rod 75, and the left side of the electric push rod 76 is fixedly connected to the sleeve plate 71. By arranging the spring telescopic rod 75 and the electric push rod 76, the spring telescopic rod 75 can be driven to move laterally. When the spring telescopic rod 75 moves to the left, it squeezes the inner wall of the spiral groove 73, prompting the cross bar 70 to drive the fan blade plate 72 to rotate, thereby transporting the gas and transporting it to the boiler to assist the combustion of boiler fuel.

[0022] See also Figure 3 The top of the spring telescopic rod 75 is provided with an inclined surface 77, and the right side of the cross bar 70 is fixedly connected with a limiting plate 78. By setting the limiting plate 78, the lateral movement distance of the moving tube 74 is limited to prevent the moving tube 74 from separating from the cross bar 70.

[0023] See also Figure 2 The top and bottom of the activated carbon filter plate 6 are both sleeved with a U-shaped seat 79, one side of the U-shaped seat 79 is fixedly connected to the inner wall of the square tube 1, and a fixing plate 710 is fixedly connected to the right side of the U-shaped seat 79, and a guide rod 711 is fixedly connected to the side opposite to the fixing plate 710. A moving block 712 is sleeved on the surface of the guide rod 711, and a cleaning plate 713 is fixedly connected to the left side of the moving block 712. Cleaning cotton is bonded to the left side of the cleaning plate 713. By setting the U-shaped seat 79, the activated carbon filter plate 6 is supported and positioned, which is convenient for the installation of the activated carbon filter plate 6. By setting the guide rod 711, the moving block 712 is guided to facilitate the vertical movement of the moving block 712. By setting the cleaning plate 713 and the cleaning cotton, it is convenient to clean the dust adhering to the right side of the activated carbon filter plate 6, so as to avoid dust accumulation and clogging of the activated carbon filter plate 6.

[0024] See also Figure 2 The top and bottom of the moving tube 74 are fixedly connected with a connecting rope 714. The end of the connecting rope 714 away from the moving tube 74 passes through the U-shaped seat 79 and is fixedly connected to the moving block 712. A spring 715 is provided on the surface of the guide rod 711. By setting the spring 715, tension is generated on the moving block 712, which facilitates the return of the moving block 712.

A handle is fixedly connected to the surface of the connecting plate 8. A mesh cover 9 is sleeved on the right side of the square tube 1. The interior of the mesh cover 9 is filled with a desiccant bag. By providing the connecting plate 8 and the handle, it is convenient to pull the handle to pull out the activated carbon filter plate 6 and replace the activated carbon filter plate 6.

[0026] When in use, the electric push rod 76 is controlled to operate, driving the spring telescopic rod 75 to move to the left, and the spring telescopic rod 75 moves to squeeze the inner wall of the spiral groove 73, prompting the cross bar 70 to drive the blade plate 72 to rotate forward, so that the gas flows. The gas passes through the mesh cover 9, the desiccant, the activated carbon filter plate 6, the cross pipe 2, the sleeve 3, the gas outlet cover 4 and the gas outlet head 5 in sequence, and is transported to the boiler cavity to provide dry and clean gas to the boiler. When the spring telescopic rod 75 moves to the right, the inclined surface 77 contacts and squeezes the inner wall of the spiral groove 73, so that the top of the spring telescopic rod 75 shrinks away from the spiral groove 73, and does not cause the direction of the cross bar 70 to rotate;

[0027] When the spring telescopic rod 75 moves to the left, it simultaneously drives the connecting rope 714 and the moving block 712 to move, and the moving block 712 drives the cleaning plate 713 and the cleaning cotton to move vertically, so as to wipe and remove dust from the activated carbon filter plate 6 to avoid clogging of the activated carbon filter plate 6.
