True or False: A high flue gas temperature does not necessarily mean large flue gas losses ( ). Thank you for your support; for correct answers, an additional +5–8 points will be given, while for incorrect answers, +1 point will be added. For those in the top 50, +3 points will be awarded regardless of whether the answer is correct or not
A high flue gas temperature does not necessarily mean large flue gas losses. The impact of flue gas temperature on boiler efficiency: The main factors affecting flue gas heat losses are flue gas temperature and flue gas volume. The higher the exhaust temperature is compared to the ambient temperature, the greater the exhaust volume, and the greater the exhaust losses
x The higher the flue gas temperature, the greater the flue gas loss. A 10°C increase in flue gas temperature results in a 0.5%–0.8% increase in flue gas losses.
A high flue gas temperature does not necessarily mean large flue gas losses (Wrong)
