How to solve low boiler flue gas temperature
Thread Content
One set of fluidized-bed boilers with a capacity of 75 tons per hour in our plant is currently operating at a load of around 40 to 50 tons per hour, with a gas recovery rate of nearly 1 ton per hour (this amount varies and can be higher or lower). The exhaust temperature of the boilers is currently around 120°C. The sulfur content in the bituminous coal used in our plant is about 1%. Is this exhaust temperature on the low side? I would appreciate it if you could help me calculate it – how should the lower limit for the exhaust temperature be determined? Furthermore, what should be done if it is too low?
At this load, a flue gas temperature of 120 is excellent; moreover, given the sulfur content of your coal type, corrosion at such a low temperature is virtually non-existent
How is the lower limit of the exhaust gas temperature calculated?
Isn’t that great? As long as it’s not below 110, there should be no problem
