As a rule of thumb, a 1% increase in the boiler efficiency is expected for each 5°C (9°F) increase in the feedwater temperature. • Use of air preheaters to transfer energy from stack flue gases to combustion air. The stack flue gas heat recovery equipment (i.e., air preheaters...
The equipment is equipped with automatic water injection, pressure control, water shortage protection and alarm, very low water level automatic shutdown, overpressure protection, overpressure relief valve and other protective measures. Adopt tubular feed water and built-in steam and water...
