Background
Waste gas generated in the heating process of a common gas or fuel oil industrial kiln is generally directly discharged into the atmosphere, but some products (such as carbon products, foamed ceramics and the like) have high organic volatile matters, and can volatilize or thermally crack under the high-temperature environment in the kiln to generate combustible gas, and the combustible gas is mixed with flue gas generated after fuel combustion to form combustible waste gas containing one or more combustible gases, and the direct discharge of the combustible waste gas can cause great pollution to the atmospheric environment. Conventionally, such combustible waste gas is delivered to a dedicated waste gas incinerator for re-incineration, so that the combustible waste gas is fully incinerated and then discharged, which not only increases the treatment cost of the combustible waste gas, but also causes fuel waste.
Therefore, how to provide a kiln nozzle that can carry out secondary safety burning in returning the kiln with the combustible waste gas that the kiln produced in service again is the research objective of the utility model.
