· Pressure drop across a 4 stage preheater used to be 500 to 550 mmwg. Any increase in number of stages resulted in additional pressure drop which unfavorably offset gain in fuel efficiency. Therefore cement industry continued for quite some time with 4 stage preheaters till cyclones of low pressure design were developed.

S. Laroche in Steam Generators for Nuclear Power Plants 2017 4.2.2.3 Preheater thermal plate leakage. The integral preheater with crossflow usually includes a thermal plate that separates the feedwater from the recirculating flow from the downcomer flow entering the tube bundle. There is a small clearance gap between the tubes and the thermal plate and leakage is possible through this gap.

The leakage rate and its direction are dependent of the pressure drop across the thermal plate with higher pressure drops resulting in higher leakage rates. If the feedwater leaks from the preheater into the recirculating flow the preheater efficiency and steam generator thermal output are reduced as a fraction of the feedwater mixes with the hot recirculating flow below the thermal plate.
