Abstract

PURPOSE:To maintain the best burning condition by a method wherein an air pipe for introducing the open air is arranged in an incinerator, and the outlet end part of the air pipe is opened at the upper part of a burning chamber or at a flue. CONSTITUTION:The object to be incinerated is supported on a fire grate 2 in an incinerator, the air inside of air pipes 7 is heated by the burning heat, the air is sucked up from a lower space 4 due to a draft action, the air temperature is raised, then blown-off toward the upper part of a burning chamber 1. Consequently, a volatile content is generated by the object to be incinerated, the condition of the volatile content is just before the burning or burning initial phase. The high temperature air is mixed with the volatile content. Thus, the high temperature and sufficient amount of air required for the burning can be obtained. Thereby, a troublesome work required for removing a burnt ash and introducing of the object to be incinerated is not necessary, also the environmental pollution can be prevented.

Description

[Detailed description of the invention] It is related to.

Incinerators that have been commonly used in the past and are equipped with a grate that supports combustible materials have a tendency to produce large amounts of incinerated ash on the grate, or large amounts of lumpy combustible material on the grate at once. When put into the air, the combustion condition deteriorated significantly due to poor air permeability.

Therefore, the ash had to be removed frequently and the material to be heated had to be added in small quantities, which was very inconvenient.

In addition, if the combustion conditions are poor, soot and smoke may be released and pollute the atmosphere.

The present invention is intended to always completely burn the materials to be burnt and eliminate the above-mentioned drawbacks.In order to achieve this purpose, the incinerator of the present invention is provided with a ventilation pipe for introducing outside air into the furnace. By opening the outlet end of the ventilation pipe into the upper part of the combustion chamber or the flue, heated outside air is supplied through the ventilation pipe to the upper part of the combustion chamber or into the flue, where unburned matter undergoes secondary combustion. It was designed so that

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a sectional view of an incinerator, in which a rectangular parallelepiped combustion chamber 1 is formed by a heat insulating wall, and a grate 2 is arranged horizontally at a slight distance from the floor surface of the combustion chamber 1. 3 is an air intake provided at the lower part of the front wall of the combustion chamber 1 to introduce outside air into the lower space 4 of the grate 2, and 6 is an upper part of the air intake 3 for introducing the object to be heated onto the grate 2. 6 indicates a flue opened at a ceiling position near the rear wall of the combustion chamber 1. Therefore, a plurality of vent pipes 7, 7... are arranged on the inner wall surface of the combustion chamber 1, and the lower ends communicate with the lower space 4 of the grate 2, and the upper ends of the oil vent pipes 7, 7... is bent inward and opened at the upper part of the combustion chamber l. The upper ends of the 93 ventilation pipes 7, 7.7 at the rear m side of the combustion chamber l face the opening of the flue 6.

FIG. 2 is a cross-sectional view of another field of view.

In the incinerator configured in this way, the materials to be burned are supported on the grate 2 and burned, and the combustion heat is transferred to the ventilation pipes 7, 7, . . .
Since the air inside is heated, air is sucked from the lower space 4 by the draft action, its temperature is raised, and it is blown out to the upper part of the combustion chamber 1. Therefore, high-temperature air mixes with the explosion just before combustion or at the beginning of combustion, which rises from the material to be burned,
Complete combustion is possible because the high temperature and sufficient air particles necessary for combustion are achieved.

In this embodiment, air is introduced from the lower part of the grate, but it may also be introduced from the upper part of the grate. Also, ventilation pipes 7, 7...
Although the vent pipe is installed bare on the inner wall surface, the vent pipe may be buried in the wall of the combustion chamber, thereby further reinforcing the furnace wall. Also, the upper end of the ventilation pipe 7.7... is the combustion chamber 1.
A secondary combustion chamber may be provided not only in the upper part of the combustion chamber but also in or on the flue and opened there. Moreover, air may be supplied using a blower if necessary.

As explained above, in the incinerator of the present invention, the air whose temperature has increased by passing through the ventilation pipe is mixed with the needles and completely combusted, so that the best combustion condition M is always maintained.

Therefore, it does not take much time to remove the incinerated ash or to put in the materials to be burned, and it also has beneficial effects such as being able to prevent air pollution.
