Abstract

PURPOSE:To reduce production of NOx, by a method wherein an electrified metallic member is disposed in the vicinity of a burner to attract a combustion flame for cooling. CONSTITUTION:A ring 9 made of a metal is earthed, and a burner body 3A is insulated from other part. The burner body is coupled to a negative pole 10a of a D.C. source 10 within a casing 1, and an electric field of about 3-10kV is generated between the burner body and the ring 9 made of metal. This enables positive ion in a combustion flame to be attracted to the ring 9 made of a metal, and increases the efficiency of contact to the combustion flame to produce an effective contact cooling action, resulting in the possibility to reduce the production of NOx.

[Problem to be solved by the invention] However, in the above conventional configuration, the produced combustion gas (flame)
The contact between the metal member and the cooling metal member is a mere contact that depends only on whether or not there is a metal member on the flow path of the generated combustion gas, that is, the relative positional relationship between the flow path of the generated combustion gas and the metal member. Therefore, the contact cooling effect of the metal member on the generated combustion gas is limited, and therefore, the NOx reduction has been limited to about 60 mm compared to a type without a cooling metal member.

In other words, due to the action of the electric field formed between the metal burner body and the cooling metal member, cations in the generated combustion gas (combustion flame in a broad sense) are attracted to the cooling metal member, which is the negative electrode. As a result, the combustion gas is also attracted to the cooling metal member, so the contact between the generated combustion gas and the metal member is much smaller than the conventional method, which relies solely on the relative positional relationship between the flow path of the generated combustion gas and the metal member. The contact efficiency could be effectively increased, and the contact cooling effect of the metal member on the generated combustion gas could be increased, thereby making the reduction rate of Now even larger than that of the previous Jo-.
