Reference numeral 26 denotes a stopper fitting which is formed so as to stop at the position shown in the figure when the lid C is opened. The lid 21 may be an ordinary iron plate, but if it is an iron plate, it is easily corroded.
Weight becomes heavy. On the other hand, with a stainless steel plate (for example, SUS304), the lid 21 that is lightweight and easy to operate can be formed because it is hard to corrode.

When incinerating garbage and the like in the garbage incinerator configured as described above, as shown in FIG. 7, the lid C is opened and garbage and the like are thrown in and incinerated. At the time of incineration, air enters through the air intake 2b of the grate skin 2 and the grate 1
The gas is supplied from the air passage 1a through the air passage 13 into the furnace body 11 through the vent hole 11b of the furnace body 11. in this case,
Even if a large amount of dust is put into the furnace body 11, the upper and lower sides burn almost at the same time even when a large amount of dust is supplied to the furnace body 11, so that the smoke is reduced and a complete combustion state is achieved.

In the above configuration, the refractory cement for forming the fire bed 1, the furnace body 11, and the heat-resistant coating 4c is a refractory material commercially available under the trade name of "Castable". "Castable" is expensive, but has high mechanical strength. Therefore, it is desirable to use "castable" for a portion that is poked by a poker or the like, such as the grate 1. Furnace body 11
No need to have the mechanical strength of the grate 1 and the amount of refractory material used is large, so if cement containing slag or "whitebait" is mixed, it has a long-term durability, It can be formed at low cost. Further, sufficient durability can be obtained even if the fire plate 2 and the furnace plate 12 are formed of a painted hot-dip galvanized steel plate or a steel plate which has been subjected to a rust-proof treatment equivalent thereto.

When the furnace body 11 is formed in a square shape, it has a good air supply property, and thus burns with a small amount of smoke. That is, when the furnace body 11 has a square shape, dust is unlikely to accumulate at the four corners, so that it is considered that the air supply property is improved. The furnace body 11 may be round, but in this case, it is desirable to devise so that the ventilation holes are not blocked by dust.

[0015]

Since the refuse incinerator of the present invention is constructed as described above, it has the following effects.

Since the lid C is large, even large dust such as a paper box or pruning waste from a garden tree can be easily introduced.

Since the supply of combustion air to the furnace body made of a refractory material is good, any dust will be completely smoked with little smoke.

Since the lid of the dust inlet is made of a stainless steel plate, the lid does not corrode even if the combustion gas stays in the vicinity of the chimney, so that long-term durability can be expected.

Since the furnace body is made of a refractory material, it has good heat retention in the furnace and is suitable for incineration of garbage.
