Abstract

The invention relates to a progressive switchover heat storage type combustion device. The progressive switchover heat storage type combustion device comprises at least five heat storage type combustors connected with a hearth and a controller capable of controlling the heat storage type combustors. The controller switches over the heat storage type combustors, so that the heat storage type combustors are alternately used for combustion or smoke exhaust, and the number of the heat storage type combustors used for smoke exhaust is made to be larger than that of the heat storage type combustors for combustion at any moment; in combustion production, when the controller switches over any heat storage type combustor, at least another heat storage type combustor maintains combustion work. Compared with the prior art, in the steering process of the device, the phenomena of detonation and furnace blast are effectively avoided, the safety performance is better, and the energy-saving effect is more obvious.

Description

technical field

[0001] The invention relates to a regenerative combustion equipment, in particular to a progressive switching regenerative combustion equipment. Background technique

[0002] Industrial furnaces are the main energy-consuming equipment in industrial production, and the energy consumption accounts for 60% of the total industrial energy consumption. Therefore, the research on its energy-saving technology is of great significance.

[0003] Existing industrial furnaces generally use regenerative combustion systems to recover and utilize the waste heat of flue gas. However, the regenerative combustion systems currently used at home and abroad are all arranged in pairs, that is, one group of regenerative burners is used for combustion, and the other group of the same number of regenerative burners is used for smoke exhaust, and the timing is reversed. The heat accumulator alternately stores and releases heat. In this kind of regenerative combustion system with pai...
