Description

Flameless combustion gas homogenizing module Technical Field The invention relates to the technical field of flameless combustion, in particular to a flameless combustion gas-homogenizing module. Background Flameless combustion is a common heating means in chemical reactors. Flameless combustion means that the gas and air are mixed homogeneously in advance before entering the combustion chamber. The combustion rate is only dependent on the ignition and combustion reaction rate, and is faster than that of flame combustion, the flame is short, and no obvious flame contour exists, so the combustion is called flameless combustion, and belongs to power combustion However, when the existing chemical reactor works, because the reaction methanol or methanol solution is sprayed to the catalyst to react rapidly, the concentration of the methanol is high at the place close to the spray head, the concentration of the methanol is low at the place far away from the spray head, and even some places cannot contact the methanol at all, no heat is generated, and a very high temperature gradient difference is caused.
