Can the heating furnace in a diesel hydrogenation unit use a high-hydrogen burner?
Thread Content
The hydrogen content in the fuel gas pipeline network of our factory is relatively high (hydrogen content is close to 90% (vol)). The heating furnace of the diesel hydrorefining device needs to use this fuel gas. Does anyone know if there are any heating furnaces that use burners that burn high hydrogen? Is this burner special?
Yes, but 90% hydrogen content is too much. Our company’s fuel gas contains about 70% hydrogen.
The hydrogen content is too high, which is not conducive to safety. It can easily cause the temperature at the top of the furnace to be too high, but the furnace temperature cannot be raised.
When the hydrogen content is too high, it is easy to fail to raise the furnace temperature, but it does not affect other things. Sometimes the hydrogen content in our gas can reach more than 70%, and the temperature rise of diesel hydrogenation is still acceptable. There is no need to worry about the furnace temperature not being able to raise it, so the impact is not big, and no special burner is needed.
The hydrogen content is so high that building a PSA or membrane separation device will bring good benefits. Why burn it? It is too wasteful.
If the furnace temperature can be raised, it won't affect anything.
The hydrogen content of the gas burned by the diesel hydrogenation furnace of CNPC Dalian No. 7 Plant reached 85%. It used to use a Hunan burner, which exploded several times. Later, it switched to a high-hydrogen burner from Luoyang Ruichang and has been using it until now. The effect is good. You can consult us.
