For example, the moisture content of the fuel as fed into the furnace may vary from 25 to 55 wt% for bark and sawmill by?products, and be less than 10 wt% for pellets. Also, the ash sintering temperatures of biofuels used cover a wide range (800 to 1200\u00b0C), as do particle shapes and sizes. Fuel quality can be improved by suitable pre-treatment technologies, but this increases costs.<\/p>\n<p>Different combustion technologies are available to deal with various fuel qualities &#8211; less homogeneous and low-quality fuels need more sophisticated combustion systems. Therefore, and for &#8220;economy of scale&#8221; reasons, only medium and large-scale systems are suitable for low-quality and cheap biofuels. The smaller the combustion plant, the greater the need for fuel quality and homogeneity.<\/p>\n<table style=\"height: 354px;\" border=\"1\" width=\"291\" align=\"right\">\n<tbody>\n<tr>\n<td style=\"width: 281px;\"><img loading=\"lazy\" decoding=\"async\" class=\"\" src=\"https:\/\/task32.ieabioenergy.com\/wp-content\/uploads\/sites\/24\/2017\/03\/pellets.jpg\" width=\"325\" height=\"245\" border=\"0\" \/><\/td>\n<\/tr>\n<tr>\n<td style=\"width: 281px;\"><i><span style=\"font-size: small;\">Clean and dry woodpellets are an ideal fuel for combustion in small-scale installations<\/span><\/i><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The chemical fuel composition has a direct influence on combustion characteristics, ie energy content, ash deposition, emissions, corrosion mechanisms, as well as ash behaviour inside a boiler.
