Abstract
The invention relates to a gas combustor which comprises a housing. A combustion chamber is formed inside the housing. The housing is square and is provided with an air nozzle and a fuel gas inlet which are communicated with the combustion chamber. A first burner and a second burner are arranged on the left and right sides of the housing respectively. The first burner is arranged on the same side with the fuel gas inlet and is located below the fuel gas inlet. At least one air retaining wall for separating the first burner from the second burner is arranged in the combustion chamber, and the air retaining walls are lower than the combustion chamber. A high temperature fuel gas flue is reserved between the ends of the air retaining walls and the inner walls of the housing. Two-stage combustion is adopted, so that it is guaranteed that fuel gas burns sufficiently. Due to cooperation of the two burners and the air retaining walls, the flowing path of fuel gas in the combustion chamber is changed so as to prolong the residence time of fuel gas in the combustion chamber; the contact time of fuel gas and flame nozzles of the two burners is prolonged, so that the combustion ratio is high, and the cost for later purification treatment is reduced. The gas combustor is simple in overall structure and environmentally friendly, and saves energy.
