Regarding the exhaust gas temperature at the chimney inlet, suction
Thread Content
At the inlet of the 5.5-meter coke oven chimney, the exhaust gas temperature is around 235°C, with a suction force of 350 PA. The temperature in the machine-focal flue is around 245°C, with a suction force of 190 PA. Is a standard temperature of 1280°C appropriate? Thank you.
Please provide the type of heating gas, its calorific value, and its composition!
It uses coke oven gas; its calorific value, as determined through previous tests, is around 16,000 kJ/m3 or so.
The exhaust gas temperature is too low; it should be around 280 at the chimney inlet!
To avoid affecting the flue draft, the total flue temperature should not be lower than 250 degrees Celsius
What is the suction force at the base of a chimney for a 900,000 tons/year coke oven using ramming process (H=125m), or in other words, what is the minimum suction force?
To avoid affecting the flue draft, the overall flue temperature should not be lower than 250 degrees Celsius. If waste heat recovery technology for flue gases is used, the temperature of the flue gases entering the chimney must remain above 180 degrees
