Bekdemir, C. (author), Doosje, E. (author), Seykens, X. (author)At present, the hydrogen combustion engine has gained renewed interest from the heavy-duty internal combustion engine (ICE) industry as an enabler for fast decarbonization of well-to-wheel emissions and reinforced by the vast commitment of key stakeholders to establish a green hydrogen infrastructure. Past studies have often focused on partial...conference paper 2022

Pan, W. (author), Bekdemir, C. (author), Willems, F. (author)A model-based control approach is proposed to give proper reference for the feed-forward combustion control of Partially Pre-mixed Combustion (PPC) engines. The current study presents a simplified first principal model, which has been developed to provide a base estimation of the ignition properties. This model is used to describe the behavior...conference paper 2022

Abelha, P.M.R. (author), Leiser, S. (author), Pels, J.R. (author), Cieplik, M.K. (author)To demonstrate the benefits of upgrading biomass, six samples of unique materials were combusted under pulverized fuel conditions aiming at the demonstration of complete coal replacement. These fuels were: sugarcane bagasse (SCB) (raw and steam exploded); sugarcane trash (SCT) (steam exploded and washed þ steam exploded); empty fruit bunch ...article 2022

Tang, C. (author), Tukker, A. (author), Sprecher, B. (author), Mogollon, J.M. (author)The European Union (EU) has set a 37.5% GHG reduction target in 2030 for the mobility sector, relative to 1990 levels. This requires increasing the share of zero-emission passenger vehicles, mainly in the form of electric vehicles (EVs). This study calculates future GHG emissions related to passenger vehicle manufacturing and use based on stated...article 2022

Tosti, L. (author), van Zomeren, A. (author), Pels, J.R. (author), Comans, R.N.J. (author)Purpose: This study evaluates the potential of biomass ash as raw clinker material and the influence of biomass feedstock and thermal conversion technology on biomass ash properties. Methods: A set of criteria for biomass feedstock and ash properties (i.e. CaO/SiO2 ratio and burnability) are established. A large dataset was collected and the...article 2021

Luo, X. (author), Grossbichler, M. (author), Waschl, H. (author), Donkers, M.C.F. (author), de Jager, B. (author), Willems, F.P.T. (author)When controlled in an open-loop fashion, both stationary and dynamical diesel engine performance can deteriorate due to disturbances. Although cycle-to-cycle fuel injection control has the potential of reducing the performance degradation by manipulating the fueling profile in real time, this potential has not been thoroughly studied. This is...article 2021

Vlaswinkel, M.G. (author), de Jager, B. (author), Willems, F.P.T. (author)Internal Combustion Engines (ICEs) are getting more complex in order to meet the limits set by tightening emission regulations. As a result, the control problem of ICEs is also getting more complex, due to an increased number of subsystems and actuators. In this paper, an input-output scaling and pairing procedure based on measured input-output...conference paper 2021

(author)The aim of this work was to evaluate the performance of three different supported amine sorbents in a 6-step vacuumswing adsorption (VSA) cycle through process simulation and optimization for a representative post-combustion CO2capture system. Detailed process optimization revealed that all the adsorbents were able to achieve the desired purity...article 2021

Evaluation of Steam-Exploded Wood Pellets Storage and Handling Safety in a Coal-Designed Power PlantAbelha, P. (author), Cieplik, M.K. (author)Solid biofuels are currently used in increasing volumes to replace fossil equivalents. Next to the traditional wood derived fuels, the advancement of biomass upgrading technologies like steam explosion (SE), followed by pelleting, further broadens the variety of materials on the market. This thermochemical and mechanical upgrading improves...article 2021

(author)Residential wood combustion (RWC) is a major source of air pollutants in the Nordic and many other countries. The emissions of the pollutants have been estimated with inventories on several scopes, e.g. local and national. An important aspect of the inventories is the spatial distribution of the emissions, as it has an effect on health impact...article 2021

Boot, H. (author), Pérez, S.R. (author)The present paper describes the theory behind the “plume rise from warehouse or pool fires model” as implemented in the software package EFFECTS. This model simulates the rising of buoyant plumes due to the density difference between the hot combustion products and the ambient air. The plume rise model calculates the maximum height at which the...article 2020

Biomass combustion is widely recognized as one of the important options to contribute to the necessary CO2 emissions reductions in the EU and World-wide on short term. Both large-scale (co-)firing of biomass in coal-designed plants, as well as dedicated stand-alone CHP units can deliver the necessary contributions to the reduction targets. This...other 2020
