Quantifying Savings From Improved Boiler Operation

In the case of a boiler, combustion gas velocity, V, is directly proportional to combustion gas mass flow rate, m g. Since every other term on the right side of the equation is a constant, the convection coefficient, h, is proportional to combustion gas mass flow rate, mg, to the 4/5 power. h ∼ m g 4/5 (15)
