These&nbsp;briquettes&nbsp;play a crucial role in various industries, including steel production, energy generation, and even environmental applications.&nbsp;However, many producers face challenges with the quality of their&nbsp;coal briquettes, particularly when it comes to high&nbsp;ash content. This&nbsp;factor not only affect the performance of the&nbsp;briquettes&nbsp;but also influence combustion efficiency, fuel economy, and overall product quality.

This residue primarily consists of mineral components such as clay, oxides, and salts, all of which are non-combustible. During the combustion process, ash forms two main byproducts:<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>Fly Ash<\/strong>&nbsp;(fine particles, &lt;90\u03bcm, carried by flue gases)&nbsp;(This data is based on the &#8220;Emissions Standards for Air Pollutants from Thermal Power Plants&#8221; (GB13223-2011) and common standards in coal combustion processes)<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>Bottom Ash<\/strong>&nbsp;(coarser, molten or solid remnants expelled from the furnace bottom)<\/p>\n\n\n\n<p data-block-type=\"core\">Chemically, ash is composed of metal and non-metal oxides, including SiO\u2082, Al\u2082O\u2083, Fe\u2082O\u2083, and CaO, all of which originate from the coal&#8217;s natural mineral matter.<\/p>\n\n\n\n<p data-block-type=\"core\">In terms of coal quality,&nbsp;ash content&nbsp;is an essential indicator. High-quality coal or washed coal typically contains less ash (e.g., 5\u201310% for washed anthracite), while raw or poorly processed coal can have ash levels exceeding 15%. A high ash content not only reduces the coal&#8217;s energy value but also leads to equipment wear, lower combustion efficiency, and increased pollutant emissions, creating environmental concerns.<\/p>\n\n\n\n<p data-block-type=\"core\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"root-causes-of-high-ash-content\" data-block-type=\"core\"><strong>Root Causes of High&nbsp;Ash Content<\/strong><\/h2>\n\n\n\n<p data-block-type=\"core\"><strong>Low-Quality Raw Materials:<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">Coal&nbsp;types like lignite or sub-bituminous coal, especially when unprocessed, naturally have higher ash content, which can severely affect&nbsp;briquette&nbsp;quality. Poor-quality coal leads to inefficient combustion and compromised product performance.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>Inadequate Preprocessing:<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">Insufficient washing or screening processes fail to remove mineral impurities. For example, improper crushing or washing can leave clay and silt particles mixed with the coal powder, resulting in higher ash content.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>Binder-Related Issues:<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">Some low-quality&nbsp;<a href=\"https:\/\/www.jianjiebinder.com\/zh\/how-to-choose-the-right-binder-for-coal-briquettes\/\" target=\"_blank\" rel=\"noreferrer noopener\">\u7c98\u5408\u5242<\/a>&nbsp;can introduce additional inorganic elements or fail to adequately bind the coal particles. This results in poor impurity separation during the briquetting process, allowing ash-forming minerals to remain in the final product.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>Suboptimal Briquetting Parameters:<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">Inconsistent mixing of coal and binder or insufficient compression pressure can lead to uneven distribution of ash-forming minerals. This concentration of minerals in certain areas of the briquette lowers its overall quality.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\" data-block-type=\"core\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"1024\" src=\"https:\/\/jianjiebinder.com\/wp-content\/uploads\/2025\/09\/Raw-material-wet-test-768x1024.jpg\" alt=\"Raw material wet test\" class=\"wp-image-18574\" style=\"width:500px\" srcset=\"https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/Raw-material-wet-test-768x1024.jpg 768w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/Raw-material-wet-test-225x300.jpg 225w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/Raw-material-wet-test-1152x1536.jpg 1152w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/Raw-material-wet-test-1536x2048.jpg 1536w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/Raw-material-wet-test-9x12.jpg 9w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/Raw-material-wet-test-scaled.jpg 1920w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\" data-block-type=\"core\">Raw material wet test<\/p>\n\n\n\n<p data-block-type=\"core\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why-ash-content-matters-its-impacts-on-industrial-processes\" data-block-type=\"core\"><strong>Why&nbsp;Ash Content&nbsp;Matters: Its Impacts on Industrial Processes<\/strong><\/h2>\n\n\n\n<p data-block-type=\"core\"><strong>Reduced Combustion Efficiency:<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">Ash&nbsp;content&nbsp;doesn&#8217;t contribute to heat generation; instead, it absorbs and dissipates heat. When the ash content in&nbsp;coal briquettes&nbsp;increases, the gross calorific value (GCV) in coal decreases, and the furnace temperature decreases, leading to higher fuel consumption and increased operational costs.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>Equipment Damage and Downtime:<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">At high temperatures, ash can fuse and form slag, which clogs furnaces, boilers, and gasifiers. This slagging disrupts heat distribution, accelerates metal corrosion, and necessitates frequent maintenance or shutdowns for cleaning.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>Quality Contamination:<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">In metallurgical processes, such as steelmaking, high ash content in\u00a0coal briquettes\u00a0can introduce impurities into molten steel, compromising product quality and raising waste rates.<\/p>\n\n\n\n<p data-block-type=\"core\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"improve-the-quality-coal-briquettes-by-managing-ash-content\" data-block-type=\"core\"><strong>Improve&nbsp;the Quality&nbsp;Coal Briquettes&nbsp;by Managing Ash Content<\/strong><\/h2>\n\n\n\n<p data-block-type=\"core\">Managing the levels of&nbsp;ash content&nbsp;in&nbsp;coal powder briquettes&nbsp;is crucial for ensuring high-quality, efficient, and environmentally-friendly products. While raw material selection and process adjustments play a big role, using the right binder can make a world of difference.&nbsp;<a href=\"https:\/\/www.jianjiebinder.com\/zh\/Coal-Briquettes-Binder-\/\" target=\"_blank\" rel=\"noreferrer noopener\">Jianjie&#8217;s binder<\/a>&nbsp;solutions provide the perfect balance between performance and sustainability, helping producers improve&nbsp;briquette&nbsp;quality, enhance combustion efficiency, and reduce environmental impact.<\/p>\n\n\n\n<p data-block-type=\"core\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-to-reduce-ash-content-in-coal-briquettes\" data-block-type=\"core\"><strong>How to Reduce\u00a0Ash Content\u00a0in\u00a0Coal Briquettes<\/strong><\/h2>\n\n\n\n<p data-block-type=\"core\"><strong>Selecting Low-Ash Coal:<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">Prioritize&nbsp;coals&nbsp;with naturally low&nbsp;ash content, such as anthracite or washed coal. By selecting the right raw materials, you can effectively reduce the ash content in the&nbsp;coal briquettes&nbsp;and minimize the residual ash after combustion.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>Washing Process:<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">In some cases, coal washing can effectively remove mineral impurities and further reduce&nbsp;ash content. Investing in advanced washing and screening equipment ensures that the raw materials meet process requirements and are free from unwanted mineral matter.&nbsp;<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>Optimizing&nbsp;Coal&nbsp;Briquetting&nbsp;Conditions:<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">Optimizing parameters such as temperature, pressure, and humidity during the&nbsp;briquetting&nbsp;process can help reduce the&nbsp;ash content&nbsp;in the final product. For example, applying high pressure (80\u2013150 MPa) during briquetting tightly compacts coal particles, minimizing voids where ash-forming minerals might accumulate.&nbsp;<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>Using High-Quality Binders:<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">Selecting the right binder, like Jianjie&#8217;s advanced binder solutions, helps improve the overall quality of coal briquettes.
