Issues with the composition of coke oven flue gas
Thread Content
Hello everyone, I have a question: 1. If blast furnace gas is used as fuel, or if blast furnace gas is mixed with coke oven gas, will there be components such as dust in the resulting coke oven gas in actual production? Is it because of this that clogging occurs in the heat storage material? ? 2. A certain space is left above the heat storage material in the heat storage chamber for ammonia injection – can this help reduce NOx levels? Are there any safety risks such as explosions associated with ammonia spraying? Thank you all for your answers!
1. There is a standard for the dust content in blast furnace gas; it should be 15 mg/m3. The main components of blast furnace dust are alkali metal oxides； 2. The temperature in the upper space of the regenerator is around 1250–1300 degrees; when the air flow is downward, the air excess factor is approximately 1.3. At this temperature range, ammonia is oxidized to NOx.
Thank you very much for your reply! Thanks!
