a gas combustion chamber

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.

Description

Technical field: [0001] The invention relates to the technical field of stove manufacturing, and more specifically relates to a gas combustion chamber. Background technique: [0002] The gas combustion chamber is a device that generates high-temperature flue gas by burning combustible gases such as acetylene, natural gas or propane. It is also a key device for the heat source of the hot blast stove. The combustion efficiency of the gas in the combustion chamber is directly related to the heat treatment effect of the hot blast stove. While traditional gas combustors, such as figure 1 As shown, it mainly includes a shell 1' and a burner 2'. The burner 2' is set on the same side as the gas inlet 3', and is set opposite to the combustion chamber gas injection port 4'. The gas enters the combustion chamber and burns through the burner. , the high-temperature flue gas produced is sprayed by the gas injection port 4' to provide heat for heating the furnace, but because the burner ...

While traditional gas combustors, such as figure 1 As shown, it mainly includes a shell 1' and a burner 2'. The burner 2' is set on the same side as the gas inlet 3', and is set opposite to the combustion chamber gas injection port 4'. The gas enters the combustion chamber and burns through the burner. , the high-temperature flue gas produced is sprayed by the gas injection port 4' to provide heat for heating the furnace, but because the burner 2' is set opposite to the gas injection port 4', and there is no barrier in the combustion chamber, the residence time of the gas in the combustion chamber is short, and The contact area between the burner nozzle and the gas is limited, resulting in insufficient combustion and low combustion rate. Among them, part of the gas is burned to produce high-temperature flue gas, and the other part of unburned gas is ejected from the gas nozzle along with the high-temperature flue gas flow, which is the heating furnace. For heat supply, the flue gas after heat exchange needs to be purified before it can be discharged up to the standard, which increases the flue gas purification process, which is costly and consumes a lot of energy
