Embodiment 1

[0021] High-efficiency and energy-saving internal dust removal hand-fired boiler, refer to the attached Figure 1-3 , is a dual-purpose boiler for hot water and steam, including a boiler body with a furnace door 28 and a drum 10. The drum 10 is located on the upper part of the boiler body. The outside of the drum 10 is connected to the water wall 3. The boxes 5 communicate with each other, and two sealing walls 4 are arranged in the inner cavity of the boiler body, and the inner dust removal room 6 used as the dust removal space between the two inner sealing walls 4, the inner dust removal room 6 separates the inner cavity of the boiler into the left combustion chamber 1 and the left combustion chamber on both sides. The right combustion chamber 2, the sealing wall 4 is isolated from the left combustion chamber 1 and the right combustion chamber 2, and the left combustion chamber 1 and the right combustion chamber 2 are communicated through the communicating flue 7 passing thro...

Embodiment 2

[0030] High-efficiency and energy-saving hand-fired boiler with internal dust removal, suitable for hot water boilers, refer to the attached Figure 4-6 The difference from Embodiment 1 is that the drum 10 is a hot water tank, which is connected to the hot water tank connecting pipe 30 through the hot water tank connecting flange 31, and the hot water tank connecting pipe 30 communicates with the upper header 35, and the upper header 35 passes through The water wall 3 is connected to the lower header 5; the water wall 3 is a tube plate cast iron part, which is used as a sealing wall and a downcomer 9; the boiler drum 10 is provided with a hot water output pipe 15 for outputting hot water, and the drum 10 is connected to the boiler water inlet pipe 14 The boiler water inlet pipe 14 connects the economizer water outlet 16 to the water inlet 17, and the economizer water outlet 16 runs through the economizer 19 to absorb the heat of the economizer 19.
