Disclosure of Invention
The utility model aims at providing a through changing big fire hole flame spray angle and small fire flame spray angle, make flame burning gather hot area and more tend to bottom of a boiler center, improve flame combustion temperature simultaneously to this further improves combustion thermal efficiency's inner flame gathers and draws gas combustion ware.
In order to achieve the above purpose, the utility model adopts the following technical solution. The inner flame gathering injection gas burner comprises a furnace tray base, a big flame burner and a small flame burner, wherein the big flame burner and the small flame burner are arranged above the furnace tray base, the small flame burner is arranged at the central position above the furnace tray base, the big flame burner is arranged around the small flame burner, the small flame burner comprises a circular arc cap-shaped shell, the outer circumference of the circular arc hat-shaped shell is provided with a small fire discharging hole, a small fire burner injection pipe communicated with the inner cavity of the circular arc hat-shaped shell is arranged between the circular arc hat-shaped shell and the furnace disc base, the big fire burner comprises an annular shell, the inner ring of the annular shell is in an inverted circular truncated cone shape, the inner ring of the annular shell is provided with a big fire discharging hole, a big fire burner injection pipe communicated with the inner cavity of the annular shell is arranged between the annular shell and the furnace plate base, the big fire burner injection pipe and the small fire burner injection pipe both adopt Venturi pipe injection structures, and the included angle between the inner ring of the annular shell and the horizontal plane is 80-90 degrees.
The inner flame gathering injection gas burner has an included angle of 20-90 degrees between the small fire discharging holes on the outer circumference of the circular arc hat-shaped shell and the horizontal plane.
The inner flame gathering injection gas burner is characterized in that 3-6 rows of small fire discharging holes which are uniformly distributed and have 20-50 in each row are formed in the outer circumference of a circular arc hat-shaped shell.
The utility model discloses owing to adopted above-mentioned technical solution, therefore following beneficial effect has, at first the inner flame gathers and draws and penetrates the big flame of gas burner innovative design and has jetted in order to be close the horizontal mode, little flame of burner sprays for being close vertical mode in the center, little fiery hole increases flame absorption secondary air area for a plurality of intensive designs simultaneously, it is more abundant to make flame burning, flame temperature obviously improves, make flame more gather in the bottom of a boiler after big or small fire mixes, thereby improve combustion thermal efficiency greatly, the totality is than original product improvement 3 percentage points. Secondly, the number of the small fire discharging holes is increased, the heat load is increased, and the combustion heat efficiency is improved.
