System and methods for controlling operation of a recovery boiler to reduce fouling

A computer-implemented method of reducing a rate of fouling in a recovery boiler system and thereby reducing an amount of time spent executing cleaning processes, the method comprising:

• receiving, by a computing device, boiler operating information for a period of time, wherein the boiler operating information includes a plurality of boiler operating parameters and a rate of fouling for the period of time, and wherein the plurality of boiler operating parameters include a plurality of boiler input parameters;
• performing, by the computing device, a regression analysis to determine at least one correlation between a combination of two or more of the plurality of boiler operating parameters and the rate of fouling, wherein the combination of the two or more of the plurality of boiler operating parameters includes at least one boiler input parameter;
• causing, by the computing device, the at least one boiler input parameter to be adjusted based on the at least one correlation to minimize the rate of fouling;
• and
• transmitting, by the computing device, the at least one adjusted boiler input parameter to a boiler controller device for implementation.

A non-transitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by one or more processors of a computing device, cause the computing device to perform actions for minimizing a rate of fouling in a recovery boiler and thereby reducing an amount of time spent executing cleaning processes, the actions comprising:

• receiving, by the computing device, boiler operating information for a period of time, wherein the boiler operating information includes a plurality of boiler operating parameters and a rate of fouling for the period of time, and wherein the plurality of boiler operating parameters include a plurality of boiler input parameters;
• performing, by the computing device, a regression analysis to determine at least one correlation between a combination of two or more of the plurality of boiler operating parameters and the rate of fouling, wherein the combination of the two or more of the plurality of boiler operating parameters includes at least one boiler input parameter;
• causing, by the computing device, at least one boiler input parameter to be adjusted based on the at least one correlation to minimize the rate of fouling;
• and
• transmitting, by the computing device, the at least one adjusted boiler input parameter to a boiler controller device for implementation.
