Abstract
The utility model relates to a partial pre-mixing burner, comprising an outer bushing, an inner bushing and a flow-revolving device. The utility model is characterized in that the outer bushing and the inner bushing have the same shaft and present a taper shape; a through-hole with an inward obliquity is arranged on the bushing-ring between the outer bushing and the inner bushing. The utility model adopts the through-hole with an inward obliquity arranged on the bushing-ring between the outer bushing and the inner bushing, so a through mixing of the one-time air, the second-time air and the burnable air can be guaranteed. The utility model has the advantages that the air-over coefficient is low; the boiler burning efficiency is high; the burnable air of low heat-value can also be burnt; besides, the utility model is beneficial for the environment protection.
Description
Technical field
The utility model relates to field of combustion technology, the partially premixed burner that particularly a kind of boiler is used.
Background technology
Reasonably the proportioning of control fuel quantity and air capacity is the essential condition that guarantees the full combustion of fuel in the boiler, under the condition that guarantees full combustion of fuel, make air capacity surpass the required theoretical air requirement minimum of burning, be coefficient of excess air hour, ignition temperature is the highest, the stove firing rate is the fastest, fuel consumption is minimum, the overcoat and the interior cover of at present used pre-mixing type combustion apapratus are straight barrel structure, the axis of through hole and sleeve line parallel, its shortcoming is that primary air can not fully mix with auxiliary air, fuel gas, causes the efficiency of combustion of boiler to descend.
Summary of the invention
The purpose of this utility model provides the partially premixed burner that a kind of coefficient of excess air is little, efficiency of combustion is high.
The utility model is achieved in that it comprises overcoat, interior cover and cyclone, it is characterized in that overcoat and interior cover are coaxial and is the vertebra shape, and the collar between interior cover and the overcoat is provided with the inside through hole in inclination angle.
The utility model is because the collar between interior cover and the overcoat is provided with the inside through hole in inclination angle; therefore can guarantee that primary air fully mixes with auxiliary air, fuel gas; have that coefficient of excess air is little, the efficiency of combustion height of boiler, low-calorie fuel gas also incendivity, be beneficial to the advantage of environmental protection.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described
Fig. 1 is the structural representation of partially premixed burner.
The specific embodiment
As shown in Figure 1, this partially premixed burner comprises overcoat 1, interior cover 2, cyclone 3 and the collar 4, overcoat 1 and interior cover 2 are coaxial and be the vertebra shape, the collar 4 between interior cover 2 and the overcoat 1 is provided with the inside through hole in inclination angle 5, during work primary air, fuel gas under the effect of cyclone 3 with auxiliary air mixing after-combustion by through hole 5.
Claims (1)
1, a kind of partially premixed burner, it comprises overcoat, interior cover and cyclone, it is characterized in that overcoat and interior cover are coaxial and is the vertebra shape, the collar between interior cover and the overcoat is provided with the inside through hole in inclination angle.
