Abstract

The invention discloses a premixed regenerative combustion device. The premixed regenerative combustion device comprises a furnace body, wherein a hearth is arranged in the furnace body; three branch pipes are arranged at the lower part of the hearth and sequentially connected with a first regenerative chamber, a second regenerative chamber and a third regenerative chamber from left to right; the first regenerative chamber is fixedly connected with an induced draft fan through a flue gas pipeline; a flue gas reversing valve is arranged in the flue gas pipeline; a first gas pipeline is mounted at the lower part of the first regenerative chamber; a gas valve is arranged in the first gas pipeline; a control wrench is mounted on the outer side of the gas valve; a second gas pipeline and a combustion-supporting gas pipeline are correspondingly arranged on the left side and the right side of the lower part of the second regenerative chamber; and a combustor is arranged in each of the first regenerative chamber, the second regenerative chamber and the third regenerative chamber. The premixed regenerative combustion device is smooth in smoke discharging, stable in furnace pressure, high in total flue gas waste heat recovery rate, and uniform in in-furnace temperature distribution, realizes high-temperature nitric oxide combustion and is more energy-saving, environment-friendly and safer.

Description

technical field [0001] The invention relates to the technical field of regenerative burner equipment, in particular to a premixed regenerative combustion device. Background technique [0002] Regenerative high-temperature air combustion technology is a new concept combustion technology that appeared in the late 1980s. Industrial furnaces using this technology can reduce fuel consumption, reduce pollutant emissions, increase production, etc. Regenerative heat exchange technology has been widely used in heating furnaces of metallurgical enterprises such as aluminum furnaces. The traditional regenerative combustion device uses a regenerative flue gas waste heat recovery device, which alternately switches air or gas fuel and flue gas through the regenerator, and the regenerator absorbs the waste heat of the flue gas to heat the air or gas fuel , in order to be able to recover the waste heat of high-temperature flue gas to the greatest extent, and make the temperature distribut...
