In order to realize the sufficient combustion of fuel and achieve the effect of no smoke, an inner shell is arranged in the shell, a plurality of rows of through holes are arranged on the inner shell at intervals and uniformly, the through holes are used for communicating the annular cavity with the combustion cavity, and each row of through holes are arranged around the inner shell.
As the preferred scheme, five rows of through holes are arranged, the lowest row of through holes is arranged on the side of the second air inlet and is not higher than the top of the second air inlet, and the rest four rows of through holes are positioned on the upper part of the inner shell.
More preferably, the upper part of the inner shell is provided with a necking section, and two rows of through holes close to the top of the inner shell are arranged on the necking section.
More preferably, the two rows of through holes in the middle are arranged close to the necking section.
Preferably, the axes of the first air inlet and the second air inlet are perpendicular to each other but do not intersect.
Preferably, the fuel inlet is located directly above the side opposite the second air inlet.
Preferably, the housing is of cylindrical configuration.
Has the advantages that: when the combustion chamber is used, one part of air enters the combustion chamber through the first air inlet to provide sufficient oxygen for fuel combustion, the other part of air enters the annular chamber through the second air inlet firstly and then enters the combustion chamber through the through holes to further provide sufficient oxygen for fuel combustion and secondary combustion, and because the plurality of rows of through holes are formed above the second air inlet, the air can uniformly enter the upper part of the combustion chamber, so that sufficient oxygen is provided for the upper space of the combustion chamber, the sufficient combustion of the fuel is realized, and the smoke-free effect is achieved; on the other hand, in the fuel combustion process, because negative pressure can be formed in the combustion chamber, the external air can smoothly enter the combustion chamber from the through hole, and a fan is not needed for air induction. Because the water tank is not arranged on the side wall of the hearth, and the fan is not used, the whole structure is simpler, the weight is smaller, and the transportation is convenient.

FIG. 1 and FIG. 2 are schematic structural views of a hearth of a composite device of a gasifier water heater in an embodiment;
FIG. 3 is a schematic sectional view of the hearth structure of the composite device of the gasifier water heater in the embodiment.
Detailed Description
The following detailed description will be made with reference to the accompanying drawings, but the present invention is not limited to these embodiments, and the modifications made to the present invention will fall within the scope of the claims of the present invention without departing from the principles of the present invention.
Examples
As shown in fig. 1 to 3, the hearth structure of the composite device of the gasifier water heater comprises a shell 9, the shell 9 is a cylindrical structure, a top plate 10 with a smoke outlet is arranged at the top of the shell 9, a fuel inlet 6 and a furnace ash outlet are arranged on the shell 9, a combustion chamber 5 is arranged in the shell 9, a furnace bridge 2 is arranged below the combustion chamber 5, a first air inlet 1 is arranged on the shell 9 and below the furnace bridge 2, a second air inlet 7 is arranged on the shell 9 and above the furnace bridge 2, the first air inlet 1 is directly communicated with the combustion chamber 5, and the second air inlet 7 is communicated with the combustion chamber 5 through an annular chamber 4.
