How to observe the flame and combustion condition in coke oven high-air heating
Thread Content
Recently, I used high-temperature heating to observe the combustion, but the results weren’t very accurate! Could someone give me some advice? ! The exhaust gas analysis isn’t very accurate! What’s the level of error required for it to be visible to the naked eye? Is the pressure at the fire viewing hole higher than it is during coke gas operation? ! ! How to tell! ! ! I’m eager to learn from you! ! ! This post was last edited by Zihua Xiao on 2009-3-4 21:45]
Whether it is high-pressure or coke gas, the purpose of adjustment is to ensure its proper combustion in order to achieve the highest thermal efficiency. When heated with blast furnace gas, the flame channel is clear and transparent, and the flame cannot be seen. Of course, at lower furnace temperatures, a pale blue flame can be seen at the furnace tip. It’s difficult to judge just because no flames can be seen when heating the blast furnace. If you can see the flames, it is normally gas burning at the air inlet. It completely covers the air chute opening; if the vertical flue becomes turbid, it indicates a high amount of gas. If the gas burns right at the exit of the gas chute as soon as it emerges from it, this indicates that the amount of gas is low (though this is not absolute; such a judgment needs to be made by taking into account the pressure at the viewing port as well as the brightness levels at the air and gas chutes). In the coal and air chutes, the chute with lower gas flow will be lit, while the one with higher gas flow will be dark. Short circuits due to poor sealing in the regenerator, along with an excessive amount of air, can cause \"white eyes\". Under conditions of proper combustion, the pressure at the monitoring hole is higher than that of the coke oven gas (you’ll need to look this up in a book; typing is too tedious). As a precaution, increase the suction force when monitoring and taking temperature readings, so as to avoid any harm. This post was last edited by 26722672 on 2009-3-5 22:37.]
Thank you!!!!!!! Let’s communicate more!
