The invention relates a combustion device for premixed gas and non-premixed gas intense whirl mutual-pre-heating combustion. Problems that combustion air and gas are not mixed uniformly; mixing strength is not high; gas stream field distribution is hard to be uniform; and combustion temperature is not high are effectively solved. A porous smoke outlet is formed in the lower part of a mixing combustion chamber; at least a pair of mixer barrels is arranged on a round barrel body of a wall body of a combustor; a gas inlet pipe and an air outlet pipe which are vertically symmetrical are arranged on outer ends of a barrel body of a mixer; an air stream adjustment nozzle which extends into the barrel body of the mixer is arranged at an outer end closed part; an inner end of the barrel body of the mixer obliquely communicates with the mixing combustion chamber through the mixer nozzle; and an air stream separation plate which is fixed on an inner wall of the barrel body of the mixer is arranged in the barrel body of the mixer. By adopting the combustion device, gas and air whirl pre-mixing combustion features are improved; whirl combustion is enhanced in the intense whirl mixing combustion chamber; a technical effect of super enthalpy combustion; and integral controllability of a combustion process is realized.
Description
technical field [0001] The invention relates to an airflow control and combustion equipment used in heat utilization equipment of industrial furnaces and kilns, in particular to a combustion device for preheating and combustion of premixed gas and non-premixed gas with strong swirling flow. Background technique [0002] At present, with the optimization of the process and the increasingly prominent environmental protection issues in industrial furnaces, higher requirements are put forward for the efficient combustion and adjustable combustion of the combustion process of the burner. Under the condition that the combustion technology has made great progress, how to Utilizing strong swirling flow to realize high-intensity self-preheating combustion, so as to significantly increase the combustion intensity and temperature, and even generate a local combustion temperature exceeding the theoretical combustion temperature, is an urgent problem to be solved at present.
