Abstract

PURPOSE:To shorten combustion time by intermittently burning a combustion burner at a predetermined time interval, and jetting a fuel from a nozzle upon non-combustion of the combustion burner to force the fuel to permeate an article to be burned and again burning the article with the combustion burner. CONSTITUTION:After an article 2 to be burned is charged into a combustion chamber, operation is started. Combustion burners 3, 4 are intermittently burned at a predetermined time interval to fire and burn the article. Upon non- combustion of the combustion burners 3, 4, a liquid fuel is jetted in a mist state from a nozzle 13 for example to permeate the article 2 and the article 2 is again burned with the combustion burners 3, 4. Thus, the article is effectually burned. Trees and plants with relatively high moisture content such as turf for example can be effectually burned and hence burning time can be shortened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incinerator for completely burning general combustible waste such as garbage, plastics and urethane foam.

[0002]

2. Description of the Related Art For example, Japanese Unexamined Patent Publication No. 4-148108 discloses one in which an incinerator such as a combustible waste is put into an incinerator and a burner installed on a wall of the incinerator burns the incinerator.
It is shown in Japanese Patent Publication No.

On the other hand, vegetation such as turf contains much more water than the residue discharged in kitchens of ordinary households, and a combustion burner with a calorific value enough to incinerate general garbage etc. It cannot be incinerated enough.

This is because the garbage such as plants and trees contains a very large amount of water, so that simply applying the combustion flame of the combustion burner to the garbage burns the surface of the garbage and the temperature of the central portion is increased. It did not rise and was spending a lot of time in the incineration work.

[0005]

Therefore, the calorific value of the combustion burner is increased so that the combustion flame is directly applied to the incineration object, and the incineration object is heated to a high temperature to be incinerated. There is a problem that the fuel consumption increases and the maintenance cost increases.

Further, when the combustion burner is enlarged, the incinerator body is enlarged, and when the amount of incineration material is small, the internal temperature of the combustion chamber rises and the chamber wall is thermally deformed. is there.

[0007]

According to the present invention, there is provided a combustion chamber for accommodating and burning an incineration object, a combustion burner mounted on a side wall of the combustion chamber, for ejecting a combustion flame toward the combustion chamber, Fuel jetting means for jetting fuel toward the combustion chamber,
The fuel injection means and a control means for controlling the combustion burner are provided, and the control means intermittently burns the combustion burner at predetermined time intervals, and the fuel injection means when the combustion burner is not burning. Is configured to eject fuel.

Further, according to the present invention, the fuel injection means is constituted by a nozzle of a combustion burner.

Further, according to the present invention, the control means is configured such that the non-combustion time during which the combustion burner is not burned is shorter than the combustion time, and the combustion time is set according to the type of incineration object. It is provided with means.

[0010]

When the operation is started after the incineration object is put into the combustion chamber, the control means controls the fuel injection means and the combustion burner to intermittently burn the combustion burner with a predetermined time interval. While igniting and burning the incinerated matter, when the combustion burner is not burning, for example, liquid fuel is ejected in a mist state from the fuel ejection means to permeate the liquid fuel into the incineration object,
By incinerating these by the subsequent combustion of the combustion burner, the incineration object is efficiently incinerated.

Further, by constructing the fuel jetting means by the nozzle of the combustion burner, it is not necessary to add a member dedicated to the fuel jetting, and for example, only by changing the control of the combustion burner,
It can be constructed relatively inexpensively.

Further, by the combustion time setting means, for example, the combustion time is set long when the water content of the incineration object is large, and the combustion time is set short when the water content is low. By setting the combustion time of the combustion burner according to the type, it is possible to efficiently incinerate the incineration object, thereby shortening the incineration time.
