Abstract
The present invention provides a coal feeding control method and system for a small pulverized coal silo, the method includes: acquiring a boiler load increase signal, and determining the target function F(t) for boiler load control obtaining the current coal mill output signal B(t), where B(t) is the fuel quantity signal at the outlet of the coal mill that changes over time from the start time; comparing B(t) with F(t): if B(t) cannot meet the fuel quantity requirements of F(t), activate the small pulverized coal silo connected to the boiler; otherwise, the small pulverized coal silo remains inactive; determining the coal feeding signal f(t) for the small pulverized coal silo, and further determining the coal feeding control signal f(t) for the small pulverized coal silo; controlling the small pulverized coal silo to feed coal to the boiler, quickly changing the combustion rate in the furnace, and increasing the boiler load.
