The pot and the furnace are both undergoing a heat conversion process. The interface between heat release and heat absorption is called the heating surface. The boiler heats water into steam. In addition to the pot and the furnace, there are also auxiliary equipment such as frames, platforms, escalators, combustion, slag discharge, smoke and air ducts, pipes, furnace walls, etc. The working principle of the boiler is to convert the chemical energy of the fuel into the heat energy of flames and flue gas through combustion, and then convert it into the heat energy of water and steam through heat transfer.

[0035] When in use, first add enough water into the water storage chamber 8 through the water adding pipe 2, and fill all the heating water pipes with water through the water delivery pipe 4, and make the return pipe 3 reflux the water, then open the chamber door 9 to add coal into the combustion chamber 6, then start the igniter to ignite the coal, and start the blower at the same time to draw in outside air through the air intake pipe. After the coal is ignited, open the box cover 11 to add enough coal into the coal storage box 5, and the high-temperature flue gas generated by the combustion of the coal will be discharged through the exhaust pipe 12 and the air delivery pipe 25. The high-temperature flue gas entering the exhaust pipe 12 will transfer the energy of the high-temperature flue gas to the water under the action of the heat conduction ring 13, and the water vapor generated by the water heating will enter the coal storage box 5 through the steam pipe 14 and the air injection hole 43 opened on the air injection pipe 42, and act on the coal in the coal storage box 5, and the ash in the ash chamber 7 can be opened by the ash discharge door 10 for regular treatment;

[0036] The energy of high-temperature flue gas can act on the water, thereby improving the heating efficiency of water and realizing preheating of coal. On the one hand, it improves the heating efficiency of water in the water storage chamber 8, and on the other hand, it improves the combustion efficiency of coal and reduces the emission of pollutants from coal combustion, thereby improving energy utilization.

[0037] Reference Figure 2 , Figure 3 , Figure 6 , Figure 8, and also includes a rotating rod 16 rotatably connected to the furnace body 1, the rotating rod 16 is provided with an impeller 15, the rotating rod 16 is fixedly connected with a stirring blade 17, the rotating rod 16 is fixedly connected with a rotating ring 23, and the outer wall of the rotating ring 23 is fixedly connected with a wiper rod 24, wherein the two ends of the rotating ring 23 are rotatably connected to the exhaust pipe 12 and the gas pipe 25 respectively, the wiper rod 24 is in contact with the inner top of the furnace body 1, the impeller 15 is arranged in the exhaust pipe 12, and the stirring blade 17 is arranged outside the exhaust pipe 12.

[0038] When high-temperature flue gas is discharged through the exhaust pipe 12, the flow of high-temperature flue gas will cause the impeller 15 to rotate, thereby driving the rotating rod 16 to rotate. The rotation of the rotating rod 16 will drive the stirring blade 17 and the rotating ring 23 to rotate. The rotation of the stirring blade 17 will stir the water in the water storage chamber 8, so that the water in the water storage chamber 8 is in a flowing state, and then the water in the water storage chamber 8 is in contact with the heat-conducting ring 13, thereby improving the heating efficiency of the water in the water storage chamber 8, so that the heat of the high-temperature flue gas transferred by the heat-conducting ring 13 can be evenly transferred to the water in the water storage chamber 8, and the rotation of the rotating ring 23 will drive the scraper rod 24 to rotate along the inner top of the furnace body 1 to scrape off the water vapor attached to the top of the furnace body 1;

[0039] The water in the water storage chamber 8 is stirred and placed in a flowing state, thereby making the water in the water storage chamber 8 heat more evenly, improving the heating efficiency of the water in the water storage chamber 8 and reducing the amount of mist-like water discharged. This is because the rotation of the wiper rod 24 will cause the amount of water droplets on the inner top of the furnace body 1 to change, so that water vapor can intermittently contact the inner top of the furnace body 1 to form water droplets, saving water resources.

[0041] The rotation of the rotating rod 16 will also cause the scraper 18 to rotate, and the rotation of the scraper 18 will cause the scraper 18 to intermittently contact the inclined protrusion 22, so that the dust filter plate 19 is in a shaking state under the action of the return spring 21;

[0042] The ash produced by the combustion of coal in the combustion chamber 6 is discharged into the ash chamber 7, which prevents the ash filter plate 19 from being blocked, causing the ash produced by the combustion of coal to accumulate on the periphery of the unburned coal, resulting in the inability to fully burn the coal. At the same time, the contact area between oxygen and coal is increased, thereby promoting the full combustion of the coal, improving the combustion efficiency of the coal, and reducing the emission of pollutants.

[0044] The water vapor discharged from the steam pipe 14 and the high-temperature flue gas discharged from the gas pipe 25 will pass through the guide ring 26, enter the guide ring 26 and contact with multiple groups of ash-removing and water-absorbing fluffs 31, and the ash-removing and water-absorbing fluffs 31 will absorb water in the water vapor and pollutants in the high-temperature flue gas. The gas passing through the guide ring 26 is high-temperature flue gas and water vapor, and because the upper opening of the guide ring 26 is large and the lower opening is small, the high-temperature flue gas and water vapor flowing through the guide ring 26 will be pressurized, so that the high-temperature flue gas and water vapor passing through the guide ring 26 have greater kinetic energy, so that the high-temperature flue gas and water vapor passing through the guide ring 26 are in the process of After being used on the blade 34, it can blow the blade 34 to rotate, so that the magnetic strip 35 intermittently overlaps with the magnetic block 32, so that the shaking rod 29 is in a shaking state under the magnetic force of the magnetic block 32 and the magnetic strip 35 and the action of the shaking spring 28, thereby making the paddle 30 and the filter 33 shake, so that the paddle 30 moves the dust removal water-absorbing fluff 31, so that the dust removal water-absorbing fluff 31 shakes and shakes off the dust and other impurities attached to its outer surface, and the shaking of the filter 33 will make the dust on the filter 33 enter the dust storage box 44 through the dust inlet 45, and the dust in the dust storage box 44 can be collected and processed by the personnel who open the box door regularly;

[0045] By setting the ash-removing and water-absorbing fluff 31, when the flue gas and water vapor pass through the ash-removing and water-absorbing fluff 31, the ash-removing and water-absorbing fluff 31 absorbs the dust in the flue gas and the moisture in the water vapor, so that the high-temperature gas discharged into the coal storage box 5 is sufficiently dry, and the water in the water vapor is prevented from acting on the coal in the coal storage box 5, causing the coal in the coal storage box 5 to be relatively moist, affecting the combustion efficiency of the coal, and also causing an increase in pollutants, thereby ensuring the combustion efficiency of the coal and reducing the pollutants generated by the combustion of the coal. At the same time, since the flue gas generated at the end of the boiler operation enters the coal storage box 5, the coal in the coal storage box 5 will absorb some pollutants in the flue gas, thereby further reducing the probability of environmental pollution caused by the flue gas being discharged into the environment, thereby achieving good protection of the environment. The ash-removing and water-absorbing fluff 31 after absorbing water can absorb sulfides, nitrides, and suspended particles in the flue gas, thereby achieving purification of the flue gas, preventing pollutants in the flue gas from being discharged into the air and causing air pollution, thereby achieving good protection of the environment.

[0046] The movement of the dust-removing water-absorbing fluff 31 by the paddle 30 ensures the adsorption quality of the dust-removing water-absorbing fluff 31 on water vapor and the processing efficiency on smoke, ensures the cleanliness of the filter 33, and facilitates the centralized processing of dust.
