状況であった。In the above-mentioned conventional refuse incinerator, the amount of air supplied to the combustion zone, that is, the appropriate value of the amount of air supplied from the first blower mechanism and the amount of air supplied from the second blower mechanism is appropriate. There is no clear standard for this, and the amount of air supplied from the second blower and the amount of air supplied from the first blower were changed as appropriate depending on the combustion state obtained from the furnace outlet temperature, etc. It was the situation that the flow rate ratio of quantity could take various values.

れる。However, if the above-mentioned flow rate ratio becomes large, the amount of air supplied from the second air blowing mechanism increases, so that diffusion combustion becomes active and gas combustion is promoted, resulting in a decrease in unburned gas concentration. However, if excessive supply is performed, the cooling action will work and the gasification phenomenon of dust will be weakened, while the amount of air supplied from the first blower mechanism will also be small, so solid combustion will be hindered and combustion speed will decrease. There was a risk that the grate combustion efficiency would decrease. Here, the grate combustion efficiency is an index of the incineration efficiency in a refuse incinerator, and is represented by the weight of incinerated refuse per unit time and unit area.

An object of the present invention is to provide a refuse incinerator capable of reducing the generation of unburned gas such as carbon monoxide without lowering the grate combustion efficiency.

点にある。In order to achieve this object, the characteristic configuration of the refuse incinerator according to the present invention is such that the flow rate ratio of the supply air amount from the second blower mechanism to the supply air amount from the first blower mechanism is about. The point is that a flow rate adjusting mechanism for setting to 0.3 or less is provided.

ガスは、第一送風機構から供給される燃焼用空気による
予混合火炎と、第二送風機構から供給される燃焼用空気
による拡散火炎により燃焼する。In general, the combustion air supplied from the first blowing mechanism contributes to the solid combustion in which the dust itself on the combustion zone burns and the gas combustion in which the combustible gas generated from the dust burns. The combustion air supplied from the blower mechanism mainly contributes to gas combustion. That is, the combustible gas generated on the combustion zone is combusted by the premixed flame by the combustion air supplied from the first air blowing mechanism and the diffusion flame by the combustion air supplied by the second air blowing mechanism.

逆に拡散燃焼抑制による冷却効果が勝り燃焼温度が低下
して火格子燃焼効率が悪くなる。When the total flow rate of air supplied from the first and second air blowing mechanisms is constant and the amount of combustion air supplied from the second air blowing mechanism increases, the complete combustion is promoted by the diffusion combustion and unburned gas If the amount of combustion air supplied from the first blower mechanism is increased, premixed combustion is promoted and the grate combustion efficiency improves, but if the extent is significant, conversely the cooling effect due to diffusion combustion suppression However, the combustion temperature drops and the grate combustion efficiency deteriorates.

とができる。Therefore, when the flow rate ratio of the amount of air supplied from the second air blowing mechanism to the amount of air supplied from the first air blowing mechanism is set to about 0.3 or less, the generation occurs as evidenced by the experimental results described below. It is possible to improve the grate combustion efficiency while promoting sufficient diffusion combustion for the combustible gas.

る。As shown in FIG. 1A, a dust sample 23 containing water is placed on a mesh-shaped sample table 22 provided in the combustion space 21 of the experimental furnace 20, and the side walls below and to the left and right of the sample table 22. While supplying the air for combustion from the above, the furnace temperature was heated to about 800 ° C. by the heating wire 24, and the combustion experiment of the dust sample 23 was conducted. Here, sample stand 2
The supply of combustion air from below 2 corresponds to the air supply by the first blower mechanism, and the supply of combustion air from the side of the sample table 22 corresponds to the air supply by the second blower mechanism.

Then, it becomes as shown in FIG. Here, the weight reduction rate is the weight reduction rate ΔW / Δt per unit time when the incineration material having the initial weight W is reduced by the weight ΔW during the time Δt, as shown in FIG. Is defined.

が判明した。From FIG. 2A, when Q2 / Q1 is 0, that is, when the air supply amount Q2 from the side of the sample table 22 is 0, Q2 / Q1 is up to about 0.3. It was found that during the period, the weight reduction rate was increased to promote the combustion of the dust sample, and when Q2 / Q1 was about 0.3 or more, the weight reduction rate was reduced and the combustion of the dust sample was suppressed.
Furthermore, from FIG. 2B, as long as the temperature inside the furnace is maintained at about 800 ° C., Q2 / Q1 is 0, that is, the case where the air supply amount Q2 from the side of the sample table 22 is 0. Based on the criteria, it has been found that diffusion combustion is promoted and the carbon monoxide concentration tends to decrease as Q2 / Q1 increases, and there is no significant difference in the amount of nitrogen oxides generated.
【0014】つまり、Q2/Q1は、第二送風機構から

することができるようになる。That is, Q2 / Q1 corresponds to the flow rate ratio of the amount of air supplied from the second air blowing mechanism to the amount of air supplied from the first air blowing mechanism. Therefore, if this value is set to about 0.3 or less,
As compared with the case where air is supplied only from the blower mechanism, it is possible to prevent the generation of unburned gas by diffusion combustion while at the same time ensuring an increase in weight reduction rate, that is, an improvement in grate combustion efficiency. Become.
