- Maximum pressure available for producing draught by the chimney is less
- Flue gases have to be discharged at higher temperature since draught increases with the increase in temperature of flue gases.
- Heat cannot be extracted from the fluid gases for economizer, superheater, air pre-heater, etc. Since the effective draught will be reduced if the temperature of the flue gases is decreased.
