Abstract:
Electronically controlled throttle valves are often used in syngas fueled engines in order to maintain the engine speed constant under variable load and gas composition conditions. The producer gas carries two macro-categories of pollutants: tars (naphthalene, benzene, toluene etc. in vapor phase) and particulate matter; a high concentration of these species leads, almost certainly, to governor stuck or failure. These malfunctions force to engine shutdown. Since it is not always possible to move towards to a better syngas filtration, especially on small scale systems, it is fundamental to investigate the way of fouling of this device. This preliminary study lead to the conclusion that a combined CFD and psychrometric approach is required for a better comprehension of the fouling phenomena.
