Patent ID: 7551982

Claim:
A method of optimizing feed rates for a cement kiln plant comprising: receiving raw material data associated with raw material for said cement kiln plant, fuel data associated with fuel for said cement kiln plant, clinker kiln dust data associated with clinker kiln dust from said cement kiln plant, and emissions data associated with emissions from said cement kiln plant; receiving a user inputted clinker composition constraint indicating a composition of clinker resulting from said cement kiln plant; receiving a user inputted solution target parameter and a user inputted selection to minimize said solution target parameter, to maximize said solution target parameter, or to match said solution target parameter to an inputted value; calculating at least one of a raw material feed rate and a fuel feed rate with a processor, based on said raw material data, said fuel data, said clinker kiln dust data, and said emissions data, such that said raw material feed rate and said fuel feed rate result in a clinker composition meeting said clinker composition constraint and in said solution target parameter being minimized, maximized, or matched to said inputted value, according to said user inputted selection; and setting a cement kiln feeder based on at least one of said calculated raw material feed rate and said calculated fuel feed rate.
