What is the typical flue gas volume for 6t/h and 10t/h circulating fluidized bed boilers?
Thread Content
I would like to ask everyone: what are the flue gas volumes for 6t/h and 10t/h circulating fluidized bed boilers respectively?
This is related to many factors such as coal quality, efficiency, and excess air ratio
I can’t provide the details for now~ May I ask what is the general range for the flue gas volume?
The coal consumption for 6t/h is approximately 2500 kg/h. Approximately 2.9 cubic meters of wet flue gas are produced per 1 kg of lignite. So, the flue gas volume for 6T is approximately 7,500 cubic meters per hour.
For the large-scale fluidized bed boiler you’re asking about, its efficiency is estimated to be around 76%; there is also significant air leakage, with the excess air ratio likely to be above 1.3. The coal used is estimated to have a calorific value of 4,000 kcal per kilogram. Based on this, a 10 T/H fluidized bed boiler consumes approximately 2 tons of coal, and the volume of flue gas produced is around 20,600 cubic meters； A 6T/H fluidized bed boiler requires about 1.28 tons of coal, with a flue gas volume of around 13,000 cubic meters. These are empirical values. Accuracy still requires calculation using formulas.
