THE USE OF A PORTABLE PROBE TO STUDY FOULING IN EXHAUST GAS STREAMS

The extent to which fouling occurs, and the effect it has on component performance, is one of the major problem areas when considering the installation of waste heat recovery units in dirty gas streams. Though the problem is of a practical nature, there is a lack of measurement techniques and consequently good data from case studies to test the proposed theoretical models. This paper describes the work recently carried out at NEL to develop such techniques aimed specifically at heat exchanger fouling.
