Description
Technical field:
The invention belongs to the fuel combustion appliance field, relate to a kind of Blowed premixed combustion apparatus specifically.
Background technology:
At present, existing commercial kitchen range air blast burner all is to adopt strong air blast diffusion type combustion technology basically, and fuel combustion is insufficient, and too much heat is also taken away in strong air blast, so the thermal efficiency of this combustion technology is low, and the energy consumption height; Simultaneously, because the coefficient of excess air of diffusion combustion is bigger, local temperature is low, causes carbon monoxide relative with the nitrogen oxide discharge capacity higher, and the pollution that causes and waste are and are big.
Summary of the invention:
The purpose of this invention is to provide a kind of premixed combustion technology that adopts fully, it can make fully burning of combustion gas (fuel oil), flame temperature is up to 1200 degree, flame temperature is even relatively, the carbon monoxide discharge capacity is low, a kind of Blowed premixed combustion apparatus that the nitrogen oxide discharge capacity is low is to overcome above-mentioned deficiency.
The objective of the invention is to be realized by following technical scheme:
A kind of Blowed premixed combustion apparatus, be by the air spray orifice, gas nozzle, air chamber, the combustion chamber, the diffusion chamber, stabilier, gas mixer chamber, fire jetting hole, fuel gas inlet, the air channel, air blast is formed, it is characterized in that: gas mixer chamber is wrapped in the air chamber, gas mixer chamber is provided with the diffusion chamber, the indoor combustion chamber that is provided with of diffusion, combustion chamber and diffusion chamber interior walls are equipped with fire jetting hole, stabilier is installed between gas mixer chamber and the diffusion chamber, gas nozzle is positioned at the gas mixer chamber middle position, fuel gas inlet is installed on the gas nozzle and is stretched out outside the air chamber, the air chamber lower end is provided with the air channel, and the rear end, air channel is installed air blast and constituted a kind of Blowed premixed combustion apparatus;
Described air chamber, combustion chamber, diffusion chamber and gas mixer chamber are hollow structure; Described stabilier 6 is alveolate texture, thickness 6～15mm, and honeycomb hole is: diameter 2～5mm, porosity 20%～50% or reticular lamina structure, the length of side are 1～2mm, porosity 20%～40%.
Advantage of the present invention is:
The present invention compares with burner with existing kitchen range, has the following advantages:
1) improved the thermal efficiency of flame temperature and burner,
The present invention adopts premixed burning fully, and the burning of fuel is also more abundant more fast, and flame is shorter, and the heat that burning produces can fully be released in the bottom of a pan, and flame temperature is even relatively;
2) reduced the discharging of nitrogen oxide and carbon monoxide;
3) stabilier is between mixing chamber and diffusion chamber, and it is more even that gas is mixed, and flow velocity is also more balanced, thereby makes each fire hole fired state of combustion chamber more consistent, can reduce combustion noise and tempering probability effectively;
4) obviously promote the class of product, met the fundamental policy of national energy-saving and emission-reduction, met the cook to demand simple to operation, more met the purpose of using user's solar term to save money.
The invention solves that too much heat is also taken away in insufficient, the strong air blast of fuel combustion, the thermal efficiency is low, energy consumption is high, local temperature is low, cause the problem of carbon monoxide and the relative higher existence of nitrogen oxide discharge capacity.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is stabilier structural representation of the present invention.
Be further described below in conjunction with the present invention of embodiment,
The specific embodiment:
Embodiment:
As Fig. 1-shown in Figure 2, a kind of Blowed premixed combustion apparatus of the present invention, be by air spray orifice 1, gas nozzle 2, air chamber 3, combustion chamber 4, diffusion chamber 5, stabilier 6, gas mixer chamber 7, fire jetting hole 8, fuel gas inlet 9, air channel 10, air blast 11 is formed, it is characterized in that: gas mixer chamber 7 is wrapped in the air chamber 3, gas mixer chamber 7 inwalls are equally distributed air spray orifice 1, gas mixer chamber 7 is provided with diffusion chamber 5, be provided with combustion chamber 4 in the diffusion chamber 5, combustion chamber 4 is equipped with fire jetting hole 8 with diffusion chamber 5 inwalls, stabilier 6 is installed between gas mixer chamber 7 and the diffusion chamber 5, gas nozzle 2 is positioned at gas mixer chamber 7 middle positions, fuel gas inlet 9 is installed on the gas nozzle 2 and is stretched out outside the air chamber 3, air chamber 3 lower ends are provided with air channel 10, and 10 rear ends, air channel are installed air blast 11 and constituted a kind of Blowed premixed combustion apparatus; Described air chamber 3, combustion chamber 4, diffusion chamber 5 are hollow structure with gas mixer chamber 7; Described stabilier 6 is alveolate texture, thickness 6～15mm, and honeycomb hole is: diameter 2～5mm, porosity 20%～50% or reticular lamina structure, the length of side are 1～2mm, porosity 20%～40%; Stabilier 6 is between gas mixer chamber 7 and diffusion chamber 5, and it is more even that gas is mixed, and flow velocity is also more balanced, thereby makes combustion chamber 4 each fire jetting hole 8 fired state more consistent, can reduce combustion noise and tempering probability effectively.
