Hofland, E.C. (author), Baran, I. (author), Wismeijer, D.A. (author)Selective laser sintering (SLS) is an additive manufacturing technique that enables the production of customized, complex products. SLS has proven itself a viable prototyping tool and production method for noncritical products. The industry has picked up on the potential of SLS, which raised the question whether it is possible to produce...article 2017

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

van Kessel, L.B.M. (author), Arendsen, A.R.J. (author), de Boer-Meulman, P.D.M. (author), Brem, G. (author), TNO Milieu, Energie en Procesinnovatie (author)Combustion of solid fuels on a grate is widely used. Mostly, the combustion behaviour is explained by the classical theory of Rogers. However, that theory cannot explain the combustion process when primary air preheating is applied. Solid fuel grate combustion is studied by experiments in a pot furnace. Experiments with and without primary air...article 2004

Slettenhaar, B. (author), Zevenbergen, J.F. (author), Pasman, H.J. (author), Maree, A.G.M. (author), Moerel, J.L.P.A. (author)Hydrazinium nitroformate (HNF) is the salt of hydrazine (N2H4) and nitroform (HC(NO2)3). Nowadays there is interest in HNF dissolved in a solvent/fuel combination. This is a promising propellant to replace hydrazine that is currently commonly used for thrusters for attitude control of satellites. TNO PML, APP and Delft University of Technology...conference paper 2003
