Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

Referring to fig. 1 and 2, the rectifying, noise-reducing and energy-saving furnace core for a compression type combustion furnace comprises a furnace core main body 1, wherein a hollow area of the furnace core main body 1 is a combustion area 10; the combustion zone 10 is composed of a combustion pool 11, an annular recess 12 and a necking zone 13 which are sequentially arranged from bottom to top; the annular recess 12 is arranged around the inner side wall of the core body 1. The fuel burns in the burning pool 11 to generate flame, and the flame is sprayed out from the burning pool 11 through the fire outlet end at the top of the furnace core main body 1 after sequentially passing through the annular recess 12 and the reducing area 13. The concave surface of the annular recess 12 is an arc surface, the top edge 121 of the annular recess 12 is in arc transition connection with the bottom edge 131 of the throat area 13, and the bottom edge 122 of the annular recess 12 is in arc transition connection with the top edge 111 of the combustion pool 11. The structural arrangement of the annular recess 12 can play a good role in rectifying flame flow, so that the noise in the operation process of the combustion furnace is effectively reduced, the flame flow can be intensively rushed out, and the noise is controlled and kept at about 50 decibels; in addition, the arrangement of the annular recess 12 increases the upward climbing stroke of the fuel along the inner wall of the furnace core main body 1, and the expansion of the lower half part of the annular recess 12 can reduce the airflow strength, weaken the thrust of the fuel, and further bind part of the fuel in the annular recess 12, thereby effectively reducing the loss of the fuel along with the airflow, improving the utilization rate of the fuel and reducing the use cost of the combustion furnace.

With reference to fig. 1 and 2, the throat area 13 has a structure with a large upper end and a large lower end and a small middle portion, a row of second air inlet holes 132 is formed in the sidewall of the throat area 13, the row is composed of 12 uniformly arranged second air inlet holes 132, and all the second air inlet holes 132 are arranged to extend from bottom to top and to the right side in an inclined manner. The combustion chamber 11 is narrow at the top and wide at the bottom, the bottom of the combustion chamber 11 is provided with a mounting hole 110 for assembling an oil inlet nozzle, and the side wall of the combustion chamber 11 is provided with first air inlet holes 112 uniformly distributed along the circumferential direction. The combustion chamber 11 is provided with two rows of first air inlet holes 112, all the first air inlet holes 112 are obliquely and extendedly arranged from bottom to top and from left side, the number of the first air inlet holes 112 in the upper row is 12, and the number of the first air inlet holes 112 in the lower row is 24. Through the opposite orientation setting of first inlet port 112 and second inlet port 132 for the air that gets into by second inlet port 132 produces a corrective action to the flame flow of rotation, makes the flame flow in combustion area 10 not take place rotary motion, and this has both reduced the noise, has also effectively reduced the orbit area of flame and the contact of combustion chamber lateral wall, reduces the loss amount of flame heat energy, guarantees the flame temperature who dashes out the combustion chamber, improves the utilization ratio of the energy. In addition, the inner wall of the combustion pool 11 is provided with an annular oil separation groove 113 distributed in the circumferential direction, the inner end of the first air inlet 112 in the previous row is arranged at the bottom of the annular oil separation groove 113, the annular oil separation groove 113 is arranged to further prevent fuel oil from climbing upwards, and the first air inlet 112 at the bottom of the annular oil separation groove 113 blows the fuel oil flowing to the annular oil separation groove 113 out of the combustion pool 11 for combustion, so that the utilization rate of the fuel oil is further improved.

With reference to fig. 2, the combustion chamber 11 has a structure in which the bottom extends from the middle portion thereof in a downward inclination toward the wall. The structure arrangement enables residual oil accumulated in the combustion pool 11 to stay at the corner of the pool bottom when the combustion furnace is not used, which can reduce the volatilization surface area of the residual oil, and the flowing air flow is not easy to pass through the corner of the pool bottom, thereby enabling the residual oil not to be easily volatilized.
