Abstract
A high temperature surface combustion burner, comprises a burner head having an air fuel mixed gas supply inlet, a burner plate secured to said burner head, wherein the burner plate is made of a ceramic porous body having more than 30% by volume of pores of 25 to 500 .mu.m in mean pore diameter; and a plurality of throughholes having a 0.05 to 5.0 mm diameter and provided in said burner plate at intervals of 2 to 30 mm and substantially vertically extending with respect to the combustion surface. Another surface combustion burner comprises a burner head having an air fuel mixed gas supply inlet, a burner element secured to said burner head, said burner element consisting of a ceramic porous body having pores sufficiently communicated from its inside to its outside for diffusing an air fuel mixed gas, wherein said ceramic porous body has 75 to 95% by volume in total of communicated pores of 0.5 to 5.0 mm in mean pore diameter; and a plurality of throughholes each having a hydraulic diameter of 0.05-5.0 mm and substantially vertically extending with respect to the combustion surface and provided in said burner element at intervals of 2 to 30 mm.
