This project has improved the process and methodology knowledge about dynamic operation and stability of biomass-fired units. The need for a high degree of regulation meant that project focus was
The project has experimentally tested several methods for sampling, test reduction and volume weight determination, ash melting point, particle size, moisture content, elements and QA of solid
This Danish-American partnership resulted in two PhD theses as well as a model for biomass firing in turbulent boiler flow. Burner maps of CO, CO2, O2, NO, NH3, HCN, SO2 as well as particle
This project consisted of two parts: Establishment of test facilities and design of a model that describes how combustion in grate-fired power plant boilers takes place. The establishment of the test
Wood is a strongly anisotropic material and likewise the char produced by pyrolysis of wood is characterized by a strong anisotropy. This anisotropic behaviour allows relatively easy transport of gas
The 'Clear Views on Clean Fuels' (VIEWLS) project aims to increase our insight into: 1) The economic and environment-technical performances of the various transport biohels, both existing biohels and
The aim is to: verify the final choice of solvent for 'Guideline for Sampling and Analysis of Tar and Particles in Biomass Producer Gas' and to develop an unambiguous method for tar evaporation with
As a continuation of preliminary experiments on super critical water cleaning a process development unit (PDU) for a capacity of 50-60 kg/h will be designed and built.
The main objectives of IEA Task 38 Greenhouse Gas Balances of Biomass and Bioenergy Systems are to calculate, analyse and assess the effects and impacts on greenhouse gas emissions of (1) substitution
The political and technical objective of the project is to ensure an efficient outcome of the Danish participation in the international work group IEA Bioenergy Agreement, Thermal Gasification of
The long-term objective of the project is to improve the energy efficiency and to increase the annual operating hours for furnaces for waste and/or biomass combustion. The project objective is
Microbially influenced corrosion (MIC) is by now a well-known phenomenon also in district heating systems. Bacteria can cause corrosion by various mechanisms including production of corrosive
One of the prime factors affecting deposit formation in straw fired furnaces is the presence of particles, which are transported from the fuel bed through the furnace by a path governed by the
Lignocellulosic biomass is an abundant and renewable source of sugars that can be fermented into high value products like ethanol. Ethanol may be used as an octane booster, fuel extender or neat fuel
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
