Optimal scheduling of a byproduct gas system in a steel …

1/6/2017 · Then, the efficiency of boiler 1# can be expressed as follows: (15) η = m × Δ H Q = ( 0.29348 Q - 1.72591) × Δ H Q = 0.29348 - 1.72591 Q × Δ H where Δ H represents the enthalpy of steam (GJ/t). Because Δ H is a constant value, η increases with increasing Q, as shown by the solid black line in Fig. 5.
