Straw-fired heating plants

In Denmark, straw-fired heating plants are widely spread. In agriculture for example, they generate heat for poultry and pig barns. In many instances, farmers also deliver surplus straw to large municipal heating plants that supply local and district heating networks. Even in a coal-fired power station, straw is burned to generate electricity. By contrast, in Germany there are only a few straw-fired heating plants in service, but there is a growing level of interest in these installations. One manufacturer in Mecklenburg-Vorpommern is producing gasification boilers for straw bales, in which whole round bales can be fired; apart from that, there are straw-fired installations that bring large rectangular bales to a mechanism that breaks them down and chops them up; then the chopped straw is transported in the air stream for burning, in dosed amounts.
