以下に記す。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a catalytic combustion device that uses hydrocarbon as fuel and utilizes its calorific value. In other words, the combustion method in which hydrocarbon fuel is supplied onto the oxidation catalyst, the oxidation reaction is terminated on the surface of the catalyst, and the generated heat is utilized makes it possible to make the combustor compact and improve the properties of the exhaust gas. This combustion method has many advantages such as: In order to make this combustion system more complete, the present invention incorporates a system in which hydrocarbons are reformed in a fuel reformer and then supplied to an oxidation catalyst. The objects of the present invention are described below.

燃焼器を提供することを目的とする。(1) Light hydrocarbon gas (natural gas, propane,
Butane), especially natural gas (methane) has poor combustibility and the reaction does not complete on the oxidation catalyst.
It was usual to slip a few percent from the oxidation catalyst. The object of the present invention is to eliminate slip from the oxidation catalyst by partially reforming natural gas and converting it into hydrogen with good combustibility. Furthermore, if hydrocarbon gas is completely reformed into inorganic gases of hydrogen and carbon dioxide, a low-temperature catalytic combustor that takes advantage of hydrogen's excellent combustibility becomes possible. In other words, combustion can be completed simply by passing the generated hydrogen gas through the oxidation catalyst without an ignition source, and by simply changing the amount of hydrogen supplied.
The purpose is to provide an excellent combustor that can obtain any temperature up to 500℃.

ル析出問題の解決を目的とする。(2) Heavy hydrocarbon fuel (kerosene) has traditionally been mainly used in small combustors of the wick type and premixed vaporization type.
Furthermore, even when using an oxidation catalyst, a small combustor requires a vaporization surface. In any of the above cases, if heavy hydrocarbon fuel is used, tar precipitation becomes a problem. That is, tar accumulates on the wick or vaporizing surface, leading to poor combustion. The present invention improves combustion performance and solves the problem of tar precipitation by reforming heavy hydrocarbon fuel into hydrocarbons or inorganic gases such as hydrogen that are lighter than the supplied fuel using a reforming catalyst and then supplying the fuel to an oxidation catalyst. The aim is to solve

る。(3) Recently, combustion exhaust gas, especially nitrogen oxides (hereinafter referred to as NO x ), has become a major problem in indoor combustion combustors. It is a common theory that NO x can be divided into thermal NO x and fuel NO x based on the generation factors. The former is generated in a flame at a high temperature of 1200°C or higher, and the latter is caused by nitrogen compounds contained in the fuel itself. In the case of kerosene used for household purposes, fuel NO x is not a problem, but only thermal NO x is a problem. However, in the case of catalytic combustion that uses an oxidation catalyst, no flame is formed, and there are no local high-temperature areas called heat islands, so compared to other combustion methods, the thermal
NO x will be significantly reduced. However, recently a CH radical-mediated NO x generation mechanism called prompt + NO x has been proposed. This is because immediately after the start of combustion, NO x
Prompt + NO x is said to be the main cause. This is caused by combustion intermediate products.
Because they are CH radicals, if hydrocarbons are reformed to CO and H2 without being directly combusted, no hydrocarbons are included, and it is said to be based on CH radicals.
Prompt＋NO x is not generated. This results in clean combustion without thermal prompts + NO x .
