I happen to have done a lot of reaserch to sensors for detection of boiler fouling lately. See the link to http://www.hukseflux.com/industry/fouling.htm
Your probem for detection of fouling can be soved by using heat flux sensors. These can be coupled to automation systems that can perform ´ntelligent sootblowing". By placing these sensors around the waterwall you will have a spatial picture. Some companies offer watercannons that will be able to perform very localised sootblowing on demand only. This will reduce the sootblowing to the minimum. These sensors also can be used for analysis of aging of tubes; an added temperature sensor can be used to follow rapid temperature changes. These changes can be compared to empirical data, and you will have a reasonably accurate picture of what lifetime can be expected.

Best regards,
