van Blijderveen, M. (author), Gucho, E.M. (author), Bramer, E.A. (author), Brem, G. (author), TNO Industrie en Techniek (author)Many municipal waste combustors use preheated primary air in the first zone to dry the waste. In most cases the preheat temperature does not exceed 140 °C. In previous experiments it is found that at temperatures around 200 °C, in some circumstances, self- or spontaneous ignition can be achieved. Using preheated air can be a powerful tool to...article 2010

(author), TNO Industrie en Techniek (author)An acoustic vector sensor array consists of multiple sound pressure microphones and particle velocity sensors. A pressure microphone usually has an omni-directional response, yet a particle velocity sensor is directional and usually has a response pattern as a figure of eight. Currently, acoustic vector sensor arrays are under investigation for...conference paper 2010

Cargnelutti, M.F. (author), Belfroid, S.P.C. (author), Schiferli, W. (author), TNO Industrie en Techniek (author)Two-phase flow occurs in many situations in industry. Under certain circumstances, it can be a source of flow-induced vibrations. The forces generated can be sufficiently large to affect the performance or efficiency of an industrial device. In the worst-case scenario, the mechanical forces that arise may endanger structural integrity. Thus, it...conference paper 2010
