Gas fired radiant emitter(100)comprising a premixing chamber(110)for preparing a premix of gas and air; a perforated ceramic plate(120)acting as burner deck; and a pilot burner(130)comprising a premix gas supply flow tube (140)and two electrodes(160, 170). The premix gas supply flow tube (140) of the pilot burner(130) extends from the side of the perforated ceramic plate (120) where the premixing chamber(110)is located, into a through hole(180)in the perforated ceramic plate(120). The premix gas supply flow tube(140)has a gas exit in the through hole(180)in the perforated ceramic plate(120)or at the combustion side of the perforated ceramic plate(120). Means(192, 194)are provided so that in an area of the perforated ceramic plate(120)around where the premix gas supply flow tube extends(140)into athrough hole(180)in the perforated ceramic plate(120),no premix gas flows through the perforated ceramic plate(120). |
