Abstract
The utility model discloses a step-type hearth combustor which comprises a furnace core, a hearth and a boiler support, wherein the boiler core is arranged on the bottom of the hearth; the boiler support is arranged on the top of the hearth; the lower part of the furnace core is provided with an air suction inlet which is connected with an air blower; the bottom of the hearth is provided with a plurality of fire outlet holes; and the inner wall of the hearth is provided with a plurality of steps from bottom to top. According to the utility model, as the diameters of the steps from bottom to top are greater and greater from layer to layer, the air flow is slower and slower upward, the noise is lowered effectively, the detection time of the high-temperature gas in the hearth is increased, and the heat utilization ratio is improved.
Description
Technical field
The utility model relates to a kind of burner that is used for gaseous fuel, relates in particular to a kind of step hearth combustor.
Background technology
At present, the burner hearth of Chinese meal stove market burner mainly is tubular and hemispherical burner hearth, surfacing.Noise is bigger in practical application, and the heat flow loss is also big, does not meet energy conservation and environment protection, presses for a kind of new-type hearth combustor and solves existing technical problem.
The utility model content
To the deficiency of prior art, the purpose of the utility model is to provide the step hearth combustor of a kind of efficiency of combustion height, energy-conserving and environment-protective, is mainly used in the burning of gaseous fuel.
To achieve these goals; The technical scheme that the utility model adopted is: a kind of step hearth combustor; Include combustion chamber, burner hearth, pan bracket, it is characterized in that said combustion chamber is located at the bottom of burner hearth, pan bracket is located at the top of burner hearth; Described combustion chamber bottom is provided with the air inlet air inlet, and is connected with air blast.
Preferably, the bottom of said burner hearth is provided with several fire output holes, and the inwall of burner hearth is provided with several steps from top to bottom.
The advantage of the utility model: be provided with step from top to bottom at the inwall of burner hearth and form the combustion chamber with combustion chamber; In use, burned flame along step and on, diameter one deck is bigger than one deck from top to bottom owing to step; Therefore air-flow makes progress away slow more more; Effectively reduce noise, and increased the holdup time of high-temperature gas in burner hearth, thereby improved heat utilization efficiency.
Description of drawings
Below in conjunction with the description of drawings and the specific embodiment the utility model is further specified;
Fig. 1 is the structural representation of the utility model;
Among the figure, combustion chamber 1, burner hearth 2, pan bracket 3, air inlet air inlet 4, air admission hole 5, fresh air inlet 6, air blast 7.
The specific embodiment
As shown in the figure, a kind of step hearth combustor comprises combustion chamber 1, burner hearth 2, pan bracket 3; Combustion chamber 1 is embedded in burner hearth 2 bottoms, and pan bracket 3 designs are at the top of burner hearth 2, and air inlet air inlet 4 is left in combustion chamber 1 bottom; And link to each other with air blast 7, the top has several fire output holes, is embedded in the bottom of burner hearth 2; Burner hearth 2 inwalls are provided with several steps from top to bottom, and pan bracket 3 designs are on the top of burner hearth 2.During use; Be provided with step from top to bottom at the inwall of burner hearth and form the combustion chamber with combustion chamber, burned flame along step and on, diameter one deck is bigger than one deck from top to bottom owing to step; Therefore air-flow makes progress away slow more more; Effectively reduce noise, and increased the holdup time of high-temperature gas in burner hearth, thereby improved heat utilization efficiency.
