[Prior Art] In conventional incinerators, the inner furnace walls, flue, heat exchanger, etc. cannot be protected against malignant gases generated inside the furnace and rapid temperature changes by using only refractory bricks, castable insulation materials, and heat-resistant paint. As a method to prevent cracking and peeling, which made it difficult to withstand long-term use, a method was proposed in Japanese Patent Publication No. 2-44103 titled ``Boiler for Garbage Incinerator'' by spraying a self-fusing alloy. However, it had the disadvantage that it could not be used on parts other than metal parts.

[Function] As an example of the combustion section of the incinerator of the present invention, the wall surface of the carbonization gasification chamber is made of steel plates.The outside of the chamber is cooled by water, and the internal combustion side is protected by a glass spray coating. Since the temperature can be lowered, the efficiency of generating carbonized gas is improved, and the durability of the furnace wall is also improved. To coat the inside of the incinerator with a glass thermal spraying device, a normal powder flame thermal spraying device is sufficient.Glass powder starts to wet and melt from the edge where it adheres to steel, bricks, castable refractories, etc., regardless of the material of the base material. This bond is completely different from thermal spraying of other ceramics, metals, and cermets, and has no porosity and a flat surface. The main factor is chemical bonding between glass and glass, which is generally not easily attacked by acids, and the various malignant gases generated inside the incinerator are acidic, so it is sufficiently durable.The surface is coated with SiO2. This makes it possible to use it to protect the interior of the incinerator, which has a quartz surface and experiences high temperatures as it burns, resulting in a significantly longer life than conventional incinerators. As for the thermal spraying method, we were able to obtain a preferable glass thermal spray coating using not only a normal powder flame spraying system but also a plasma spraying system, an induction plasma spraying system, and various thermal spraying systems that utilize a laser.

[Effects of the Invention] As described above, the incinerator of the present invention has wear resistance, corrosion resistance,
Because it has excellent heat resistance, the amount of refractory used in the incinerator can be reduced, making it possible to significantly reduce construction costs.Moreover, the water-cooled integrated structure makes installation easy, and all heat-generating parts are water-cooled. The heat source can be used without the need for a special heat exchanger, and even when the inside of the incinerator is cooled, the temperature inside the incinerator drops quickly, eliminating the need to stop the incinerator for a long period of time. Even if cracking or peeling occurs due to some kind of accident, it can be easily partially repaired by reheating or re-spraying, making it possible to significantly reduce running costs.
