With the SWGR system, offgas from selected zones of the sinter machine is mixed with hot cooler off-air and then recirculated to the sinter strand. The result is a significant reduction of the specific offgas volume to the end-of-pipe gas cleaning by up to 50%.</p><h3>Sinter cooler waste heat recovery – Transform sinter waste energy into profit</h3><p>The sensible heat of the sinter that is discharged from the sinter machine to the sinter cooler amounts to almost half of the total process thermal energy input. Primetals Technologies has developed solutions for efficient recovery of this sensible energy by utilization of hot waste air from the sinter cooler for production of steam. Special off-air recirculation concepts lead to increased plant efficiency and additionally ensure compliance with local emission standards.</p><h3>Top gas Recovery Turbine (TRT) – Transform off-gas into profit</h3><p>The blast furnace process consumes upward of 75% of the total energy in an integrated steel plant. The TRT recovers the pressure energy of the top gas of a blast furnace by controlled expansion to low clean-gas pressure. Electrical energy from the waste pressure can be gained without any additional energy input or CO2 production.</p><h3>Dry slag granulation with heat recovery – Utilization of blast furnace slag heat energy</h3><p>Primetals Technologies, voestalpine Stahl, the FEhS – Building Materials Institute and the University of Leoben joined forces in an R&D program to develop a new dry-granulation technology using air to cool molten slag and recover the lost heat energy. The slag granulate from this process fulfills the same criteria as wet-granulated slag for use in the cement industry.<br><br> Click here to learn more about our gas-cleaning portfolio for <a href="/fileadmin/user_upload/content/01_portfolio/17_eco-solutions/gas-cleaning/ECO_SOLUTIONS_-_IRONMAKING.pdf" target="_blank">ironmaking</a> facilities.<br> </p></div></div></div></div></section> <div style="display: none;"> Debug: 4 </div> <section class="main"> <div class="row"> <div class="col-xs-12 owl-carousel-images-wrap"> <div class="owl-carousel owl-carousel-images" data-loop="" data-cols="3"> <a class="images-slider images-slider-lightbox" data-loop="" data-slider-id="slider-20111" title="Selective waste-gas recirculation system" href="/fileadmin/user_upload/content/01_portfolio/17_eco-solutions/energy-efficency/swrg.jpg" > <img title="Selective waste-gas recirculation system" alt="Selective waste-gas recirculation system" src="/fileadmin/_processed_/2/0/csm_swrg_fd78172aad.jpg" width="343" height="225" /> <p class="image-caption">Selective waste-gas recirculation system</p> </a> <a class="images-slider images-slider-lightbox" data-loop="" data-slider-id="slider-20111" title="Sinter cooler waste-heat recovery system" href="/fileadmin/user_upload/content/01_portfolio/17_eco-solutions/energy-efficency/Picture2_.jpg" > <img title="Sinter cooler waste-heat recovery system" alt="Sinter cooler waste-heat recovery system" src="/fileadmin/_processed_/b/5/csm_Picture2__6368592407.jpg" width="343" height="225" /> <p class="image-caption">Sinter cooler waste-heat recovery system</p> </a> <a class="images-slider images-slider-lightbox" data-loop="" data-slider-id="slider-20111" title="TRT 3D plant layout" href="/fileadmin/user_upload/content/01_portfolio/17_eco-solutions/energy-efficency/AMEH_TRT.png" > <img title="TRT 3D plant layout" alt="TRT 3D plant layout" src="/fileadmin/_processed_/0/c/csm_AMEH_TRT_7fde244138.png" width="343" height="225" /> <p class="image-caption">TRT 3D plant layout</p> </a> <a class="images-slider images-slider-lightbox" data-loop="" data-slider-id="slider-20111" title="Pilot Plant Dry Slag Granulation at voestalpine, Austria" href="/fileadmin/user_upload/content/01_portfolio/17_eco-solutions/energy-efficency/DSC07207.jpg" > <img title="Pilot Plant Dry Slag Granulation at voestalpine, Austria" alt="Pilot Plant Dry Slag Granulation at voestalpine, Austria" src="/fileadmin/_processed_/6/9/csm_DSC07207_0d08a1a821.jpg" width="343" height="225" /> <p class="image-caption">Pilot Plant Dry Slag Granulation at voestalpine, Austria</p> </a> </div> <div id="customArrowsImages-20111" class="customArrows customArrowsImages"></div> </div> </div> </section> </div> <div id="f007ccb01659b85c54bdb0eb6162b772" class="tab-pane "> <section id="c842" class="main frame-layout frame-layout-0 "><div class="container"><div class="frame frame-default frame-type-textpic "><header><h2 class="h2__uppercase--bold"> Energy efficiency technologies for steelmaking plants </h2></header><div class="ce-textpic ce-center ce-above"><div class="ce-bodytext"><h3>Gas recovery</h3><p>LD (BOF) gas recovery is an economic solution for LD (BOF) primary waste gas treatment that is completely integrated. The main equipment for the LD (BOF) gas recovery is the gasholder plus the pressure boosters and distribution network. Beside the high efficiency the main focus is on advanced operation safety.</p><h3>Cooling stack – Highly efficient energy recovery</h3><p>Converter waste gas cooling is highly challenging due to the tough operating conditions with high loads of abrasive dust particles as well as high temperatures and the general cyclic nature of this batch process. Primetals Technologies ensures high plant availability and best performance by applying state-of-the-art and proven designs and materials and advanced dynamic simulation of process conditions</p><h3>Energy recovery for electric arc furnaces – Highly efficient waste heat recovery</h3><p>Most electric arc furnace offgas systems are not thermally optimized, so only nearly 30% of the energy input in the electric arc furnace is used further. Primetals Technologies provides electric arc furnace operators with highly efficient energy recovery systems. The integral approach is based on a modular dedusting system set-up. Basically, either the hot gas line or the forced-draft cooler or both aggregates can be exchanged by an adequate energy recovery system.</p><h3>AOD waste heat recovery – Solutions for highly efficient energy recovery</h3><p>A two stage solution helps customer to optimize waste heat recovery in accordance with waste heat utilization. Depending on the individual requirements the first cooling stage for the AOD waste heat recovery system can be realized either as hot water or steam cooled equipment. Additionally the second stage cooling equipment can be replaced by an waste heat boiler or an heat exchanger.<br> </p><p>Click here to learn more about our gas-cleaning portfolio for <a href="/fileadmin/user_upload/content/01_portfolio/17_eco-solutions/gas-cleaning/ECO_SOLUTIONS_-_SAVING_RESOURCES__CREATING_VALUE.pdf" target="_blank">steelmaking</a> facilities.<br> </p></div></div></div></div></section> <div style="display: none;"> Debug: 4 </div> <section class="main"> <div class="row"> <div class="col-xs-12 owl-carousel-images-wrap"> <div class="owl-carousel owl-carousel-images" data-loop="" data-cols="3"> <a class="images-slider images-slider-lightbox" data-loop="" data-slider-id="slider-20117" title="Switch over station for dry dedusting systems" href="/fileadmin/user_upload/content/01_portfolio/17_eco-solutions/energy-efficency/Switch_over_station_for_dry-dedusting.jpg" > <img title="Switch over station for dry dedusting systems" alt="Switch over station for dry dedusting systems" src="/fileadmin/_processed_/d/b/csm_Switch_over_station_for_dry-dedusting_79ad7800d9.jpg" width="343" height="225" /> <p class="image-caption">Switch over station for dry dedusting systems</p> </a> <a class="images-slider images-slider-lightbox" data-loop="" data-slider-id="slider-20117" title="Partially assembled cooling stack " href="/fileadmin/user_upload/content/01_portfolio/17_eco-solutions/energy-efficency/Cooling_stack_partially_assembled.jpg" > <img title="Partially assembled cooling stack " alt="Partially assembled cooling stack " src="/fileadmin/_processed_/6/d/csm_Cooling_stack_partially_assembled_ac9c5c81c0.jpg" width="343" height="225" /> <p class="image-caption">Partially assembled cooling stack </p> </a> <a class="images-slider images-slider-lightbox" data-loop="" data-slider-id="slider-20117" title="Energy recovery for electric arc furnaces " href="/fileadmin/user_upload/content/01_portfolio/17_eco-solutions/energy-efficency/Arvedi_WHR_3D.png" > <img title="Energy recovery for electric arc furnaces " alt="Energy recovery for electric arc furnaces " src="/fileadmin/_processed_/e/e/csm_Arvedi_WHR_3D_ee659047d3.png" width="343" height="225" /> <p class="image-caption">Energy recovery for electric arc furnaces </p> </a> <a class="images-slider images-slider-lightbox" data-loop="" data-slider-id="slider-20117" title="AOD 3D plant layout" href="/fileadmin/user_upload/content/01_portfolio/17_eco-solutions/energy-efficency/3D-AOD-Acroni_.jpg" > <img title="AOD 3D plant layout" alt="AOD 3D plant layout" src="/fileadmin/_processed_/d/7/csm_3D-AOD-Acroni__abfb598b26.jpg" width="343" height="225" /> <p class="image-caption">AOD 3D plant layout</p> </a> </div> <div id="customArrowsImages-20117" class="customArrows customArrowsImages"></div> </div> </div> </section> </div> </div> </div> </section> <script type="text/javascript"> jQuery(document).ready(function ($) { var tabs = '#tabs-848'; var hash = document.location.hash; if (hash.length > 0) { $(tabs + ' a[href="'+hash+'"]').tab('show'); } }); </script> <section id="c26705" class="main frame-layout frame-layout-0 "><div class="container"><div class="frame frame-default frame-type-header "><header><h2 class=""> Reference Story: Highest efficiency & safety for LD (BOF) gas recovery </h2></header></div></div></section> <section class="grid-row frame-layout frame-layout-0"> <div class="container"> <div class="row flexrow"> <div class="col-xs-12 col-md-8 grid-column"> <section id="c849" class="main frame-layout frame-layout-0 "><div class="container"><div class="frame frame-default frame-type-text "><p><strong>Customer</strong><br><a href="https://www.tatasteeleurope.com/" target="_blank" rel="noreferrer">TATA Steel Port Talbot</a>, England</p><p><strong>Typ of plant</strong><br> Gas recovery system for LD (BOF)</p><p><strong>Our solution</strong><br> Although equipped with a suppressed combustion primary dedusting system, the steel shop of TATA Steel Port Talbot (former CORUS), did not feature a gas recovery system until Primetals Technologies was awarded the contract to install the energy recovery system.
