摘要：PURPOSE:To contrive to reduce NOX and to prevent CO from generating by a structure wherein a flame temperature suppressor consisting in forming inorganic material in porous state is arranged in Bunsen flames in such a manner that the length in the direction of its thickness is included within the flames at the burner forming Bunsen flames. CONSTITUTION:The Bunsen burner 1 consists of a nozzle 2, a mixing tube 3 and flame ports 4. Primary flames 5, which are accumulated at the upper part in order to form secondary flames 6, are formed at the flame ports 4. In the above-mentioned burner, the porous state flame temperature suppressor 7, which is made of inorganic material such as SiO2 or the like in the form of honeycomb with the size of pores 8, for example, of 3-5mm., is fixed at the upper surface of the burner by means of a supporting frame 9 through mounting pieces 10. In this case, said suppressor 7 is arranged so close to the burner that the lower end of the suppressor 7 abuts the primary flames 5 at the position, for example, around 1/2-1/3 of its total length and at the same time the direction of the thickness of the suppressor 7 is rendered to be included within the secondary flame 6. Owing to the structure as mentioned above, the walls of the pores 8 of the suppressor 7 prolong the primary flames 5 during burning and at the same time absorb heat, resulting in lowering the maximum temperature of the flames in order to
accomplish the expected object.
