    • PROBLEM TO BE SOLVED: To secure a reliable ignition property.
      SOLUTION: This combustion device of very low NOx comprises a lean burner port 102 for spouting out the lean air-fuel mixture, a first rich burner port 106 for spouting out a first rich air-fuel mixture having the concentration higher than the lean air-fuel mixture, a second rich burner port 109 for spouting out a second rich air-fuel mixture of the concentration between the lean air-fuel mixture and the first air fuel mixture, and an ignition means 125 for igniting the second rich air-fuel mixture. Thus the air-fuel mixture of intermediate concentration which can be easily burnt, can be ignited, the ignition can be surely performed even when high fuel supply amount to the lean burner port is determined to achieve very low NOx, and the discharge of unburnt substances such as HC can be inhibited in ignition.

    • PROBLEM TO BE SOLVED: To provide a catalyst combustor capable of achieving low NOx ratio by employing catalyst combustion for a pre-burner, based on the fact that premixed fuel gas of high concentration is usable for the pre-burner regardless of loads on a gas turbine. SOLUTION: This catalyst combustor 1 comprises a catalyst burner 9 for ignition provided in an air inlet passage 3 of the catalyst combustor 1 to heat air flowing into a main partial oxidation catalyst carrying part 7 to catalyst ignition temperature. The catalyst burner 9 for ignition has a partial oxidation catalyst carrying part 14. Fuel concentration of premixed gas 24 flowing into the partial oxidation catalyst carrying part 14 is held to be less than a theoretical mixture ratio, and at an ignitable concentration or more in temperature and pressure conditions of air flowing into the partial oxidation catalyst carrying part 14.

    • PROBLEM TO BE SOLVED: To solve the problems that secondary air required for combustion is subject to natural induction from the outside to the inside of a cooking chamber via an opening portion of the cooking chamber and so the construction of the opening portion determines the flow-in amount and angle of the secondary air to possibly preclude an increase in the angle control range of gas flames.
      SOLUTION: This device comprises a blowing device 14 horizontally provided in a secondary air intake 32 neighboring a set of right and left lower burners 13a, 13b for forcibly taking secondary air therein with power supplied by a power source. Thus, flames are controlled to flow toward the center of the cooking chamber so that cooked objects are sufficiently and uniformly heated or the cooked objects are partially cooked corresponding to required heat quantity.
