New report on low emissions biomass combustion

Task 32 has published a new report titled “Low emission biomass combustion in automated boilers for heat and power“.

In recent years we have seen important developments in the design of biomass fueled heating plants. Both innovative designs of the primary combustion technology and innovative application of advanced secondary emission abatement technology have paved the way for plants with very low levels of emission of particles and NOx – even with low grade biomass fuels.

Some countries have seen a tremendous increase in efficiency levels of especially combustion plants utilising moist fuels. The combination of decreasing temperature levels in district heating systems and application of flue gas condensation and heat pumps in the system has paved the way for increasing the capacity without additional fuel demand.

Task 32 has reviewed these means with focus on concepts and technical consequences and highlights these developments and approaches to the benefit of potential new plant owners. The report provides an introduction to fundamentals and history of research and development over the past 30 years of primary measures and concepts as well as secondary abatement measures such as de-NOx systems. It contains examples/cases of innovative developments in the recent years from several countries such as Austria, Denmark, Netherlands and Switzerland as well as a summary and conclusion.

The publication includes a two-pager highlighting the most important fundamentals and developments.
