Recover Heat from Boiler Blowdown - Department of Energy

The 80% efficient boiler produces 50,000 pounds per hour (lb/hr) of 150-pounds-per-square-inch-gauge (psig) steam. It operates for 8,000 hours per year. The blowdown ratio is: Blowdown Ratio = 3,200 3,200 + 50,000 = 6.0% From the table, the heat recoverable corresponding to a 6% blowdown ratio with a 150-psig boiler operating pressure is 1.7 MMBtu/hr.
