Abstract

The invention discloses a combustor with two-plus-one linear arrayed fire holes. The combustor comprises a main body fire discharge piece, a secondary air adjusting plate and a gas conveying device; two-plus-one flame ports are arranged on the main body fire discharge piece; through change of structures of a gas channel and an air adjusting belt, the fire hole combustion area is increased, the combustion strength of fire hole surfaces is changed, and the flame combustion height of the fire holes is lowered; and the secondary air adjusting plate is provided with a strip intake main channel anda circular hole type intake auxiliary channel for changing a fuel combustion coefficient a1 to lower the flame so as to reduce the emission of Nox nitric oxides in the heat reaction process. The combustor reduces the flame combustion height of the fire holes, lowers the flame temperature, and obviously reduces the emission of the Nox nitric oxides in the heat reaction process of the combustor. Thecombustor has the advantages of low combustion load, low combustion vibration and low combustion noise.

Description

Technical field: [0001] The invention relates to the technical field of gas burners, in particular to a burner with two plus one line array fire holes. Background technique: [0002] Nitrogen oxides NOx include NO, NO2, N2O, N2O3, N2O4, N2O5, etc. NOx in flue gas is mainly NO and NO2. The toxicity of NO is very high. It is very easy to combine with hemoglobin Hb in the blood, causing blood hypoxia and central nervous paralysis. The affinity between NO and hemoglobin is about hundreds to thousands of times that of CO. The pollution of NOx to the environment and the harm to the human body have been widely known. [0003] The nitrogen oxides produced during the combustion process of the gas burner are mainly NO and NO2, which are usually referred to as nitrogen oxides NOx. A large number of experimental results show that the nitrogen oxides emitted by the burner are mainly NO, accounting for about 95% on average, while NO2 only accounts for about 5%. The NO produced by gener...
