The first session (2AO.2) is entitled “Production, Characterization and Quality of Solid Biofuels” and covers the development of innovative methods for solid biofuels characterization, factors influencing fuels quality, biomass management procedures to improve the fuel quality, as well as the combustion behaviour of solid biofuels. Examples include pellet production from underexploited forest and agricultural feedstocks and reduction of dry matter losses during industrial scale wood chips storage by using calcium hydroxide as additive.
Topic 2.2, “Biomass and Bioliquids Combustion for Small and Medium Scale Applications”, has one session entitled “Novel Modelling Approaches and Application of Residue-based Fuels” (2AO.5) commencing at 15:15. This session covers new CFD models for simulations of packed bed pellet combustion, alkali release from the fuel bed during biomass pyrolysis, utilisation of residues from olive production in an industrial boiler as well as utilisation of used cooking oil in novel domestic heating combustion systems. In addition, emissions modelling and a method to predict pollutants from residential wood heating appliances are addressed.
The single session of Topic 2.3 (2AO.8) starts at 17:00 and is entitled “Innovative Measures Towards High Efficiency and Availability in Large Scale Combustion”. The session deals with retrofitting of existing large-scale combustion plants, in particular aiming at fuel flexibility, including the use of additives, and high efficiency. Innovative modelling and experimental methods are also addressed to decrease maintenance costs, support failure prediction and high availability.
There will also be one visual/poster session on Monday afternoon starting at 13:30, from Topic 2.4, “Gasification for Power, CHP and Polygeneration”. Session 2AV.2 is on “Experiments and Modeling Towards Enhanced Implementation of Gasification in Systems for CHP” which addresses both integrated gasification and CHP systems, including a transportable biomass gasification unit for agricultural residues, fuel characterization and emissions in both experimental and modelling projects.
Tuesday 7th July
There are two oral sessions for Topic 2.4, “Gasification for Power, CHP and Polygeneration”. The first session, 2BO.2, begins at 08:30 with the title “Innovative Pilot-Scale Integrated Gasification CHP Systems Modeling and Demonstration”. In this session, different configurations of bench and pilot-scale gasification systems, including blaze technology for CHP applications, coupling fixed bed gasifier with char bed reactor for improved syngas quality and integration of solar drying of sewage sludge with gasification. A GIS-based modelling process for gasification power plant planning is also presented. The second Topic 2.4 oral session, 2BO.6, on “Small Scale Gasification Advanced Testing and Characterisation Related to Emissions” starts at 13:30. This session focuses on research works dedicated to small-scale laboratory characterisation of fuels for gasification and small-scale testing works and includes the catalytic role of Ca and K in energy grass char gasification, toluene cracking using char, mineral sorbents for alkali removal and cleaning of gas for use in a SOFC.
There are also two oral sessions for Topic 2.5, “Gasification for Synthesis Gas Production”. The first, 2BO.10, commences at 15:15 on Tuesday and is entitled, “Innovations in Feedstock for Gasification for Synthesis Gas Production”. In this session various feedstocks for gasification for synthesis gas production and factors affecting syngas quality, including sewage sludge gasification for syngas and ash utilisation, are discussed and analysed. Process emissions are also considered, for example through an innovative sampling apparatus for simulation of energy conversion processes. The second Topic 2.5 oral session, 2BO.14, on “Advances in Gasification Processes for Synthesis Gas Production” starts at 17:00 and covers process related factors, for example process design and equipment operating conditions, for production of syngas as well as the cleaning and upgrading possibilities, for example for advanced biofuel production from energy crops and for upgrading of synthesis gas by reforming of recycled methane.
There is one visual/poster session on Tuesday afternoon starting at 13:30, and which combines Topic 2.2 “Biomass and Bioliquids Combustion for Small and Medium Scale Applications” and Topic 2.3 “Biomass Combustion in Large Utilities”. Session 2BV.4 is entitled “Innovative Approaches for Biomass Use in Small to Large Scale Combustion Systems”. The utilisation of new challenging solid fuels and liquid fuels is addressed. Moreover, new methods to improve process control and combustion performance as well as novel approaches for combustion-based CHP technologies are outlined. This session also deals with measures aimed at increasing systems efficiency, fuel flexibility and reliability.
Wednesday 8th July
There are three visual/poster sessions, all of them in the afternoon. The first session, 2CV.4, from Topic 2.5, “Gasification for Synthesis Gas Production”, starts at 13:30. This session on “Innovations in Feedstock and Advances in Processes for Gasification for Synthesis Gas Production” focuses on various gasification feedstocks, the influence on different gasification agents as well as modelling of process conditions. In addition, gas cleaning and upgrading of syngas are discussed as well as techno-economical aspects.
The second and third visual/poster sessions are both for Topic 2.6, “Anaerobic Digestion for Biogas and Biomethane Production”. The first of the two sessions (2CV.5), “Anaerobic Digestion Session I“, starts at 15:15 and covers a wide range of biomass substrates for biogas and hydrogen production, biomass pretreatment methods, co-digestion, gas cleaning and technologies for biogas upgrading to biomethane for pipeline injection. The second of the Topic 2.6 visual/poster sessions (2CV.7), “Anaerobic Digestion Session II“, deals with biogas process performance optimization, enhanced methane yield as a function of biomass substrate, hydrogen production and integration of anaerobic digestion with other process wastes and residues.
