According to the utility model discloses a steady flame fire arranges piece of embodiment of first aspect, including fire arranges piece main part and steady flame frame 200, fire arranges the piece main part and includes the portion of drawing 120 and locate the head that draws 120 top, draws 120 and is equipped with and draws the chamber 121, and the head is equipped with the fire front chamber 142 and main flame hole 150, and main flame hole 150 locates the top of fire front chamber 142, and fire front chamber 142 and draw the chamber 121 and communicate; the flame stabilizing frame 200 is sleeved outside the head, the top of the flame stabilizing frame 200 is open, the bottom of the flame stabilizing frame 200 is hermetically connected with the fire grate segment main body, an auxiliary flow channel 201 is arranged between the flame stabilizing frame 200 and the head, the flame stabilizing frame 200 is provided with a throttling section and a diffusion section arranged on the upper side of the throttling section, and the width of the diffusion section is greater than that of the throttling section; the forefire chamber 142 is provided with a second necking section 141, the second necking section 141 is concavely arranged towards the inner side of the forefire chamber 142, a plurality of first through holes 143 are arranged on the second necking section 141, the forefire chamber 142 is communicated with the auxiliary runner 201 through the first through holes 143, and the second necking section 141 is arranged at the lower side of the throttling section.

For example, as shown in fig. 1 to 3, the fire row piece main body and the flame holding frame 200 have a front-back dimension in width and a transverse dimension in length; the fire grate main body is sequentially provided with an injection cavity 121, a transition cavity and a fire front cavity 142 from bottom to top, wherein the transition cavity is provided with a first necking section 131, the fire front cavity 142 is provided with a second necking section 141, and the first necking section 131 and the second necking section 141 are respectively processed to be concave towards the inner side; the flame holding frame 200 is sleeved outside the pre-fire chamber 142, the bottom edge of the flame holding frame 200 is arranged at the lower side of the second necking section 141, and because the second necking section 141 is recessed towards the inner side of the fire row piece main body, a cavity with a certain volume is formed at the bottom of the auxiliary flow channel 201, and meanwhile, the width of the upper part of the flame holding frame 200 is larger than that of the lower part of the flame holding frame, so that the middle part of the auxiliary flow channel 201 is narrower, and the upper part and the lower part of the flame holding frame are wider.

By arranging the flame stabilizing frame 200 and the first through hole 143, when the gas-air mixed gas reaches the second necking section 141, part of the mixed gas flows out of the first through hole 143 and enters the auxiliary flow channel 201; because the middle part of the auxiliary runner 201 is narrow, the mixed gas is prevented from directly flowing out, the mixed gas forms turbulent flow in the cavity at the bottom of the auxiliary runner 201, the part with large mixed gas kinetic energy is diffused to the part with small kinetic energy in the length direction, the mixed gas is fully mixed and uniformly distributed in the cavity at the bottom of the auxiliary runner 201, and finally flows out from the top of the auxiliary runner 201 to form uniform auxiliary flame, the root of the main flame is heated, and the effect of stabilizing the main flame is achieved; meanwhile, the width of the part of the pre-ignition cavity 142 located at the second necked-down section 141 is also narrow, and the gas-air mixed gas forms turbulence at the lower side of the second necked-down section 141, so that the mixing of the gas and the air is enhanced; by arranging the second necking section 141, the mixing of the gas in the pre-fire chamber 142 and the gas in the auxiliary runner 201 is enhanced, the structure is compact, and the space is saved.

The utility model discloses an in some embodiments, the piece main part is arranged to fire still includes transition portion 130, and transition portion 130 locates the head and draws between penetrating portion 120, and transition portion 130 is equipped with the transition chamber, and the chamber 142 before the fire passes through the transition chamber intercommunication with drawing penetrating chamber 121, and the transition chamber has the first section 131 of necking down of a plurality of, and first section 131 of necking down is to the sunken setting of the inboard of transition chamber, and all first sections 131 of necking down interval from top to bottom sets gradually. As shown in fig. 2, the transition chamber has a first necked-down section 131, which is simple to process while promoting the mixing of the gas and the air, but more than two first necked-down sections 131 may be provided to achieve a more sufficient mixing effect; therefore, when the mixed gas flows to the main flame hole 150 from the injection cavity 121, the mixed gas is throttled twice, turbulence is formed below the first necking section 131 and between the first necking section 131 and the second necking section 141, so that the gas is fully mixed, the pressure and the speed of the mixed gas of the gas and the air at the main flame hole 150 are basically consistent, the combustion is uniform and sufficient, and the smoke quality is improved; the unevenness of flame at the main flame holes 150 is prevented and the heat transfer efficiency with the heat exchanger is low.

In some embodiments of the present invention, the bottom edge of the flame holding frame 200 is closely attached to the fire grate segment main body. Because the temperature of the flame stabilizing frame 200 and the fire row piece main body is higher in actual work, the sealing connection by using an adhesive is easy to damage; the bottom edge of the flame stabilizing frame 200 is tightly attached to the fire row piece main body, so that the gas-air mixed gas is difficult to leak.

In some embodiments of the present invention, the top edge of the flame holding frame 200 is provided with a fire transmitting notch, the bottom of the fire transmitting notch is provided with a fire transmitting ear 210, and the fire transmitting ear 210 extends from the bottom of the fire transmitting notch to the outside of the flame holding frame 200. The burner is generally formed by arranging a plurality of fire row sheets in parallel, and by arranging the fire transmission notch and the fire transmission lug 210, when any part in the burner is ignited, flame can be rapidly transmitted to other fire row sheets from the fire transmission notch.

In some embodiments of the present invention, the left side of the injecting portion 120 is provided with the excess material portion 110, and the excess material portion 110 is disposed below the head portion. Clout portion 110 can make its combustor portion that accords with more sizes dress installation demand through secondary operation, makes the utility model discloses can be used for the combustor of multiple model, size.

In some embodiments of the present invention, the main flame holes 150 are located at the top of the fire grate segment main body, and the top of the fire grate segment main body is flat. Present fire arranges piece because the preparation process problem, the both ends at its top can the perk, can touch the part of perk during flame burning, reduces the heat conduction efficiency of combustor and heat exchanger, the utility model discloses the top that sets up fire row piece main part is level and smooth, can not touch fire row piece main part during flame burning.

According to the utility model discloses combustor through adopting foretell steady flame row piece, and burning flame is stable.
