Abstract

The invention provides a furnace kiln continuous heat exchange control device. The device comprises a first heat storage chamber, a second heat storage chamber, a flue gas input pipeline, a flue gas output pipeline, an air input pipeline and an air output pipeline, wherein the flue gas input pipeline, the flue gas output pipeline, the air input pipeline and the air output pipeline are communicatedwith the first heat storage chamber and the second heat storage chamber. Valves are arranged on the pipelines,wherein the pipelines is used for connecting the first heat storage chamber, the second heat storage chamber with the the flue gas input pipeline, the flue gas output pipeline, the air input pipeline and the air output pipeline. The control system controls the valves between the pipelinesand the heat storage chambers to be opened and closed periodically, so that the first heat storage chamber and the second heat storage chamber can be switched periodically between heat absorption andheat release modes. The furnace kiln continuous heat exchange control device and the furnace kiln continuous heat exchange control method have the advantages that the structure and the working process is simple, the problem of short heat exchange period, high furnace temperature and large furnace pressure fluctuation in heat storage combustion caused by frequent heat exchange in the prior art canbe solved, the continuous combustion stability of the heat storage chamber can be improved, and the waste heat recovery efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of reversing combustion control, in particular to a furnace continuous heat exchange control device and control method. Background technique [0002] Regenerative combustion technology is a technology that burns under high-temperature and low-oxygen air conditions. Usually, the temperature of high-temperature air is greater than 1000°C. Regenerative combustion technology fundamentally improves the energy utilization rate of the heating furnace, especially for low calorific value fuels ( The rational use of blast furnace gas) not only reduces the emission of pollutants (blast furnace gas), but also saves energy. It has become an advanced technology that meets the current resource and environmental requirements, and the adoption of regenerative combustion technology has strengthened Excellent furnace gas circulation, uniform temperature field of the furnace, improved heating quality, and the effect is also ver...
