Abstract

The invention relates to a combustion radiator and combustion method of a multi-ejecting-tangent-circle premixing porous medium gas stove. A traditional combustion gas stove has the disadvantages that combustion efficiency is low and a large number of pollutants such as CO and NOx are discharged. The combustion radiator of the multi-ejecting-tangent-circle premixing porous medium gas stove comprises a fuel gas injector and a plurality of Venturi ejectors, wherein a rotary fuel gas mixer is arranged at the tail ends of the Venturi ejectors, a gas uniform distribution device is arranged at the upper end of the rotary fuel gas mixer, and a second-level fuel gas mixing chamber is formed in the upper end of the gas uniform distribution device, and a porous medium combustion radiator body is arranged at the upper end of the second-level fuel gas mixing chamber. The combustion radiator and combustion method of the multi-ejecting-tangent-circle premixing porous medium gas stove have the advantages that the combustion efficiency and heat efficiency are high, emission of the pollutants such as the CO and the NOx is reduced, and the variation range of a combustion load is wider.

Description

technical field

[0001] The invention belongs to the technical field of porous medium combustion, and relates to a combustion method of a multi-injection tangential circle premixed porous medium combustion radiator, which is suitable for use as a burner for civil gas stoves. Background technique

[0002] At present, in the burners of civil gas stoves, the main way of gas stoves to mix air and gas is still to adopt the method of natural injection of primary air, using the natural mixing structure of air and gas, and in order to enhance the injection effect and reduce the resistance loss , there is usually no pre-mixing chamber, which will inevitably lead to the difficulty of fully mixing the gas before it enters the stove for combustion, which will easily cause incomplete combustion, generate more CO, and reduce combustion efficiency and thermal efficiency. Therefore, how to improve the effect of gas injection air, Enhancing the premixing effect of air and gas is the main diff...
