Yet comprehensive utilisation runs at only about 32%, against roughly 56% in the EU, signalling a large efficiency gap.<\/p>\n<h2>Steel<\/h2>\n<p>The steel sector alone holds about 350 million tonnes of standard-coal equivalent in waste heat, but utilisation is below 35%, and for low-to-mid-temperature streams below 300C it is under 5%. Steel accounts for around 16% of national energy use, so recovery is a national priority: the 2024 steel action plan targets raising self-generated power from waste energy by more than 3 percentage points.<\/p>\n<h2>Cement, Chemical and Glass<\/h2>\n<ul>\n<li><strong>Cement<\/strong> &#8211; waste-heat power generation (WHG) penetration exceeds 90%, making it the most matured recovery application in China.<\/li>\n<li><strong>Chemical and petrochemical<\/strong> &#8211; high-pressure steam, purge gas and waste-heat\/pressure recovery are widely applied; the sector contributes about 19% of national WHG capacity.<\/li>\n<li><strong>Glass and non-ferrous metals<\/strong> &#8211; kiln and smelting off-gas recovery is expanding, though coverage remains lower than cement.<\/li>\n<\/ul>\n<h2>Recovery Capacity and Equipment<\/h2>\n<p>China&#8217;s waste-heat power capacity surpassed 45 GW in 2025, with steel (~38%), cement (~27%) and chemical (~19%) dominating. Leading Chinese engineering firms supply WHG systems and heat-recovery equipment. Air-to-air plate exchangers and heat pipes play a growing role in capturing low-temperature streams (30-120C) that were previously vented, often feeding the same recovery loops described in this Encyclopedia.<\/p>\n<h2>Why It Matters for Recovery Equipment<\/h2>\n<p>Most untapped potential sits in low-temperature waste heat &#8211; exactly the band where compact air-to-air and heat-pipe exchangers are most cost-effective. As policy tightens, demand for these units across steel, cement, chemical and park-level heating networks is set to rise.<\/p>\n<div class=\"yc-related\">\n<h3>\u95a2\u9023\u8a18\u4e8b<\/h3>\n<ul>\n<li><a href=\"https:\/\/www.26yc.com\/ja\/plate-vs-rotary-wheel-drying-selection\/\">Plate vs Rotary Wheel Heat Exchangers for Drying Applications: A Selection Guide<\/a><\/li>\n<li><a href=\"https:\/\/www.26yc.com\/ja\/rotary-heat-exchangers-grain-drying-towers\/\">Rotary Heat Exchangers in Grain Drying Towers<\/a><\/li>\n<li><a href=\"https:\/\/www.26yc.com\/ja\/heat-pump-low-temp-drying-air-to-air-recovery\/\">Heat Pump Low-Temperature Drying: Air-to-Air Waste Heat Recovery Principle<\/a><\/li>\n<li><a href=\"https:\/\/www.26yc.com\/ja\/outdoor-air-ratio\/\" title=\"Outdoor Air Ratio: Why 100% Outside-Air Spaces Need Recovery Most\">Outdoor Air Ratio: Why 100% Outside-Air Spaces Need Recovery Most<\/a><\/li>\n<li><a href=\"https:\/\/www.26yc.com\/ja\/datacenter-liquid-cooling-heat-recovery\/\" title=\"\u30c7\u30fc\u30bf\u30bb\u30f3\u30bf\u30fc\u6db2\u51b7\u71b1\u56de\u53ce\uff1a\u30b5\u30fc\u30d0\u30fc\u71b1\u306e\u6355\u6349\">\u30c7\u30fc\u30bf\u30bb\u30f3\u30bf\u30fc\u6db2\u51b7\u71b1\u56de\u53ce\uff1a\u30b5\u30fc\u30d0\u30fc\u71b1\u306e\u6355\u6349<\/a><\/li>\n<\/ul>\n<\/div>\n<h2>\u3088\u304f\u3042\u308b\u8cea\u554f<\/h2>\n<p><strong>How much industrial waste heat does China generate?<\/strong><br \/>China&#8217;s industrial waste-heat resource exceeds one billion tonnes of standard coal equivalent per year, with over 300 million tonnes economically recoverable but only about 32 percent utilized.<\/p>\n<p><strong>Which sectors offer the most waste-heat recovery potential?<\/strong><br \/>Steel holds about 350 million tonnes of coal-equivalent with low utilization, while cement, chemical, glass, and non-ferrous metals add large and partly tapped streams.<\/p>\n<p><strong>Why is low-temperature waste heat important?<\/strong><br \/>Most untapped potential sits below 300 degrees C, exactly the band where compact air-to-air and heat-pipe exchangers are most cost-effective and were previously vented.<\/p>\n<p><strong>What role do air-to-air exchangers play in Chinese recovery?<\/strong><br \/>Plate exchangers and heat pipes capture low-temperature streams of 30 to 120 degrees C, often feeding the same recovery loops used across process and district heating.<\/p>","protected":false},"excerpt":{"rendered":"<p>The Resource at Stake China generates the largest industrial waste-heat resource on the planet &#8211; equivalent to more than 1 billion tonnes of standard coal per year, of which over 300 million tonnes are economically recoverable.
