Optimised strawfired heating plant - OPTINOX
The purpose of this project was to show that condensing flue gasses after filtration in a bag filter is an economical and environmental friendly solution for straw fired heating plants.
Throughout the 1980ies and 90ies the environmental and energy performance of biomass based heating plants has been improved, but there is still room for improvement. There has been tests with condensing mode on straw fired boilers, bud experience with the technical solutions has not been convincing, and therefore the technology has is not been common. The purpose of this project is to demonstrate that condensing mode after a bag house filter on straw fired heating plants can be an economical and environmental success. The combination of bag house filters and condensing mode is new. The combination will reduce the content of salts and particles considerably. Based on the result of this project condensing mode is expected to be combined with air-moisturizing, and hereby the efficiency can be increased by further 5-10%
In this project Øster Toreby Halmvarmeværk has installed new bag filters and a condensing unit. The purpose of the bag filters was to separate the fine particles from the flue gas. As the bags operate at 120-130 deg. C, the largest part of the salts in the flue gas will be present as fine matter (aerosols) and therefore be separated in the filters. A purpose of the project was to investigate to what degree the salts could be separated. With a good separation the emissions can be reduced in respect to particles, HCL and sulphur compounds and the concept could be widely used.
