Abstract

The invention discloses a low-NOx burner for resource utilization of extremely low calorific value associated gas and carbon black burnout, which includes a flue gas inlet for entering the extremely low calorific value gas generated during the production process of activated carbon, and the flue gas inlet is output The end is connected to the pilot combustion chamber, and the primary air inlet is set on the pilot combustion chamber, and the low calorific value gas combusted in the pilot combustion chamber passes through the swirl channel regenerative burner and the exhaust air sent in by the exhaust air inlet. Complete combustion in the concave heat-gathering combustion chamber and furnace. The invention realizes the integrated treatment of industrial extremely low calorific value associated gas combustion, carbon black elimination and low NOx combustion. The heat of extremely low calorific value gas is effectively used, which greatly improves the efficiency of energy utilization. It can provide heat for subsequent enterprise transformation such as flue gas whitening or heating transformation, and eliminate environmental pollution such as carbon black.

Description

technical field

[0001] The invention relates to chemical manufacturing enterprises such as activated carbon and the technical field of energy conservation and environmental protection, and in particular to a burnout low NOx burner with extremely low calorific value associated gas and carbon black. Background technique

[0002] The preparation of activated carbon from raw coal generally requires two steps of treatment. One is carbonization treatment to reduce the non-carbon components in the coal, that is, the raw coal is isolated from the air for high-temperature pyrolysis, and the other is activation treatment to make the carbonized coal gasify with water vapor to produce Well-developed void structure. A large amount of carbonized pyrolysis gas and activated associated gas will be produced during the carbonization and activation process. The calorific value of these gases is extremely low, about 4% of the calorific value of methane. The main component of combustible gas is...
