A number of ash samples where collected at four Danish municipal solid waste incineration (MSWI) plants. Samples of bottom ash/slag, 2nd-3rd pass ashes and ESP/E-filter ash were collected at the
Light tar is a significant contaminant in gas thermally produced from biomass using updraft gasifiers. This tar represents a server risk with respect to formation of deposits within the gas-driven
Utilisation of biomass and waste is generally expensive and not very efficient on small and medium scale plants. For gasification systems the main problem is the gas cleaning, where severe
Uneven char conversion and in extreme cases channels have been observed in the char bed of down draft gasifier. This might lead to a reduced efficiency of the gasifier.
The aim of the project was to optimize the biogas process of high ratios of the organic fraction of municipal solid waste (OFMSW) in co-digestion with manure. Optimization was aimed with regard to
Microbiologically induced corrosion (MIC) in district heating systems is a well-known phenomenon, which to a large extend has been associated with sulphate-reduging bacteria (SRB). Detection of these
The goal of the project is to collect, promote, and communicate the knowledge of pyrolysis and related thermal conversion processes for production of fuels and chemicals from biomass.
The aim leading to the LT-CFB concept is to create better access for the efficient, clean and economic utilization of bio-fuels and waste products having a high content of slag forming and/or
The objective of this research project is to improve the electric energy efficiency of biomass fired boilers (specifically straw). The main focus of the project is on deposit formation on walls and
Despite the pre-selection of only the most promising energy solutions, the analyses and comparison of the chosen energy supply solution have revealed, that none of them are capable to turn out with an
The project has 2 objects: 1) to produce better chip quality or chunk to the gasification plants and 2) to provide essential data for the Danish as well as international standardisation work.
BIOG supplemental is a small supplement to the project BIOG, Reference: 1383/98-0003. A number of students from Norway and Denmark have wished to stay at ReaTech to perform experiments related to
This project shall prove that gasification of straw pellets and briquettes are possible with a two-stage gasification process. A rebuilding of the 100 kW test gasifier at DTU/ET will take place, and
