style=\"color: #008080;\">Additional Energy and Operational Benefits<\/span><\/h2>\n<p data-pm-slice=\"1 1 []\">Beyond the direct reduction in sootblowing steam consumption, HISS can contribute to improved overall recovery boiler efficiency through:<\/p>\n<ul data-spread=\"false\">\n<li><strong>Increased effective steam generation:<\/strong> More efficient cleaning of heat-transfer surfaces improves heat transfer and can increase steam generation.<\/li>\n<li><strong>Reduced boiler feedwater consumption:<\/strong> Lower steam demand for sootblowing reduces the need for treated boiler feedwater makeup.<\/li>\n<\/ul>\n<p>These additional benefits can further improve the overall economic performance of the installation.<\/p>\n<p>&nbsp;<\/p>\n<h2><span style=\"color: #008080;\">Performance Backed by Guarantees<\/span><\/h2>\n<p>Heat Management combines demonstrated operational results with contractual performance guarantees.<\/p>\n<p>These guarantees include maintaining or improving boiler availability and achieving a <strong>minimum 30% reduction in sootblowing steam consumption<\/strong>, with potential savings of up to 50%, depending on boiler characteristics and operating conditions.<\/p>\n<p>HISS also offers the possibility of increasing sootblowing frequency by up to 100%, while maintaining agreed performance criteria for boiler campaign duration and steam consumption.<\/p>\n<p>The above guarantees are absolute, Heat Management offers full reimbursement of the investment if the guaranteed results are not achieved.<\/p>\n<p>&nbsp;<\/p>\n<h2><span style=\"color: #008080;\">Proven Results, Measurable Savings<\/span><\/h2>\n<p>The results from these four black liquor recovery boilers demonstrate how HISS can reduce sootblowing steam consumption by <strong>30\u201333%<\/strong>, while maintaining or even increasing boiler load.<\/p>\n<p>Depending on operating conditions, local costs, and investment requirements, the payback period can be less than 12 months.<\/p>\n<p>By combining proven operational improvements with contractual performance guarantees, Heat Management makes sootblowing optimization a measurable investment in recovery boiler efficiency and performance.<\/p>\n<p>&nbsp;<\/p>\n<blockquote><p>Pour en savoir plus sur HISS Advanced et comment il r\u00e9duit la consommation
