在丹麦，政府在1995年至2002年期间为测试和安装生物质燃烧锅炉提供补贴。每种锅炉类型都必须通过官方批准测试才能获得补贴。试验前对锅炉的燃烧能力进行了优化。该补贴的主要目的是鼓励开发节能环保锅炉。因此，该计划以这样一种方式组织，即最大的补贴授予高效率和低排放的锅炉。这一目标实际上已经实现了分批燃烧秸秆锅炉，其中典型的效率已经从1995年的约75%增加到2002年的约87%。同样，一氧化碳排放量也从1995年的5000 ppm（参考值10% O-2）减少到2002年的1000 ppm以下。这些改进主要是由于燃烧室内部更好的隔热、用于向燃烧过程供应空气的更有效的技术、改进的烟气冷却以及用于空气供应的电子控制单元的优化。(C)2003 Elsevier Ltd.保留所有权利。
In Denmark, government subsidies for the testing and installation of biomass-fired boilers were available for the period from 1995 until 2002. Each boiler type had to pass an official approval test to achieve subsidy. The combustion abilities of the boiler were optimized prior to the test. The main aim of this subsidy was to encourage the development of energy-efficient and environmentally friendly boilers. The scheme was therefore organized in such a way that the greatest subsidies were awarded for boilers with high efficiency and low emissions. This goal has in effect been achieved for batch-fired straw boilers, where the typical efficiency has been increased from about 75% in 1995 to about 87% in 2002. Similarly, the carbon monoxide emissions have been reduced from 5000 ppm (reference value 10% O-2) in 1995 to less than 1000 ppm in 2002. These improvements are mainly due to better insulation inside the combustion chamber, more efficient techniques for supplying air to the combustion process, improved cooling of the flue gas, and optimization of the electronic control unit for the air supply.
