In chemistry, the burn rate (or burning rate) is a measure of the linear combustion rate of a compound or substance such as a candle or a solid propellant. It is measured in length over time, such as millimeters per second or inches per second. Among the variables affecting burn rate are pressure and temperature. Burn rate is an important parameter especially in the area of propellants because it determines the rate at which exhaust gases are generated from the burni… Webb25 nov. 2015 · For instance, a 50 MW unit that meets the aforementioned standard will have a ramp rate of at least 50/10 = 5 MW/min, but a 500 MW will have a ramp rate of at least 50 MW/min.
