How to reduce nitrogen oxide emissions from coke ovens
Thread Content
5.5-meter coke oven, standard temperature of 1285°C, flue draft of 145 Pa, damper opening of 145 mm, cycle time of 24 hours. Nitrogen oxide emissions do not meet the standards.
Upgrading the denitration equipment – it’s an inevitable trend: lol
Front-end denitration technology for coke oven gas modification
Upper denitration technology is the trend in combustion, and in the short term, the method of reducing the flame front temperature can also be employed.
He Kebin, an academician of the Chinese Academy of Engineering, said, “Where lies our new potential for emission reduction?” This requires moving towards the front end; by \"moving towards the front end,\" it means that we cannot rely on the conventional concept of using environmental protection technologies for end-of-pipe treatment, but rather we need to extend our efforts to green technologies. What are green technologies? That is, energy conservation first, diverse structures, and environmental friendliness. ”
You can try reducing the flue suction a bit and see.
The air excess coefficient is low, resulting in incomplete combustion of the gas! There is a risk of fire and explosion!
Install desulfurization and denitration devices – **environmental protection is an inevitable trend
