From 2036 onwards, the limit value drops 100 mg\/Nm\u00b3, as for new plants! [<em>In Germany, liquefied petroleum gas is treated just as strictly as natural gas, although higher emissions are hardly avoidable with identical technology<\/em>].<\/li>\n<li><em>In case 2, stricter regulations also apply. For example, the NOx limit value for natural gas or LPG for typical thermal oil heaters (> 210 \u00b0C) or steam\/hot water boilers for higher pressures (> 18barg) is also 150 mg\/Nm\u00b3<\/em>. At lower temperatures or pressures (110 to 210 \u00b0C or 0.5 to 18 barg) it drops to 110 mg\/Nm\u00b3, then a tightening to 170 mg\/Nm\u00b3 also applies to fuel oil.

In the meantime, however, the issue has come very much into focus, even for smaller installations and in countries with traditionally low energy prices (e.g. USA), and in the majority of cases our customers find that considerable savings can be achieved with relatively small additional investments.<\/p>\n<p>In addition, it is important to note that there may also be<strong> regulatory requirements regarding efficiency<\/strong>! In Germany, this is again the 44th BImSchV, which generally specifies a maximum flue gas loss of 9%. In other words, the thermal efficiency must then be at least 91%! At the usual operating temperatures of most thermal oil heaters, this cannot be achieved without additional measures.<\/p>\n<h3>How can the thermal efficiency be increased in practice?<\/h3>\n<p>A proven method which is independent of external heat sinks is the <strong>preheating of combustion<\/strong> air by means of a so-called <strong>combustion air pre-heater (German abbreviation Luvo)<\/strong>. Here, thermal power from the flue gases, which would otherwise escape unused through the chimney, is used to preheat the intake air of the burner. The resulting fuel saving is reflected in a considerable increase in thermal efficiency (typically by about 6 percentage points).<\/p>\n<\/div><\/section><\/p><\/div>\n<div  class='flex_column av-2h0m3gb-88d64c495698710db7664f381f9359bb av_two_fifth  avia-builder-el-24  el_after_av_one_full  el_before_av_three_fifth  first flex_column_div  column-top-margin'     ><section  class='av_textblock_section av-lkmd4qjb-6abeb1ce1f466d5b1a7f693a407fd661 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p class=\"reader-text-block__paragraph\">Despite an increased power requirement for the combustion air fan, very short payback times can be achieved.

Is it then an option worth considering at all?<\/p>\n<p>The answer to this is clearly YES, because this only applies to a comparable technology level! When converting to state-of-the-art low NOx burners, nitrogen oxide emissions can often be significantly reduced &#8211; despite retrofitting a Luvo! In many cases this even applies without having to resort to measures such as external exhaust gas recirculation, which would complicate the conversion.<\/p>\n<p>NESS is the right partner for this, because we know the available and already field-tested burner technology in detail!<\/p>\n<p>And what alternative or additional measures are possible?<\/p>\n<ul>\n<li>If an (external) &#8211; ideally also year-round &#8211; heat sink is available, this can also be taken into account. This is, for example, <strong>the introduction of the hot flue gases into a dryer<\/strong> (depending on the product to be dried and the fuel) as well as the<strong> extraction of heat in the form of hot or warm water<\/strong> by means of a heat exchanger. Depending on the respective temperature levels and required heat outputs, these measures can even be foreseen in addition to combustion air preheating!<\/li>\n<li>Retrofitting an <strong>O2 control system<\/strong> to limit the residual oxygen content in the flue gas. It reduces the excess air at the burner and thus reduces the amount of hot flue gas that is discharged via the chimney while the boiler output remains the same. Typically, this increases the thermal efficiency by about one percentage point, and also compensates well for slight fluctuations in the fuel composition.<\/li>\n<li>Retrofitting a\u00a0<strong>VFD for the combustion air fan<\/strong> to minimise its electrical energy demand. This measure is particularly effective when heaters run at partial load for longer periods. Then the sound level of the fan is also reduced.<\/li>\n<\/ul>\n<\/div><\/section><br \/>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lkmddvbb-85ed8a4bcd17b93c024a89cf573f8a36\">\n.avia-image-container.av-lkmddvbb-85ed8a4bcd17b93c024a89cf573f8a36 img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-lkmddvbb-85ed8a4bcd17b93c024a89cf573f8a36 .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-lkmddvbb-85ed8a4bcd17b93c024a89cf573f8a36 av-styling- avia-align-center  avia-builder-el-31  el_after_av_textblock  el_before_av_hr '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-20601 avia-img-lazy-loading-not-20601 avia_image ' src=\"https:\/\/ness.de\/wp-content\/uploads\/2023\/07\/slider-elektro-w-1030x328.jpg\" alt='' title='slider-elektro-w'  height=\"328\" width=\"1030\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/ness.de\/wp-content\/uploads\/2023\/07\/slider-elektro-w-1030x328.jpg 1030w, https:\/\/ness.de\/wp-content\/uploads\/2023\/07\/slider-elektro-w-300x95.jpg 300w, https:\/\/ness.de\/wp-content\/uploads\/2023\/07\/slider-elektro-w-768x244.jpg 768w, https:\/\/ness.de\/wp-content\/uploads\/2023\/07\/slider-elektro-w-1536x489.jpg 1536w, https:\/\/ness.de\/wp-content\/uploads\/2023\/07\/slider-elektro-w-2048x652.jpg 2048w, https:\/\/ness.de\/wp-content\/uploads\/2023\/07\/slider-elektro-w-1500x477.jpg 1500w, https:\/\/ness.de\/wp-content\/uploads\/2023\/07\/slider-elektro-w-705x224.jpg 705w, https:\/\/ness.de\/wp-content\/uploads\/2023\/07\/slider-elektro-w-1320x420.jpg 1320w\" sizes=\"(max-width: 1030px) 100vw, 1030px\" \/><\/div><\/div><\/div><br \/>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-av_hr-af89a52d51412774536fa272e468f7cd\">\n#top .hr.hr-invisible.av-av_hr-af89a52d51412774536fa272e468f7cd{\nheight:30px;\n}\n<\/style>\n<div  class='hr av-av_hr-af89a52d51412774536fa272e468f7cd hr-invisible  avia-builder-el-32  el_after_av_image  el_before_av_textblock '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div><br \/>\n<section  class='av_textblock_section av-lkqwguam-ab2816f29c97401b25640f029c3e14d5 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p>Ideally, the selected measures should be carried out simultaneously in order to make the engineering and conversion (mechanical and electrical) as efficient as possible.<\/p>\n<p>Such a conversion is also often a good opportunity to replace obsolete plant controls (replacement of contactor controls with hardware controllers by failsafe PLCs).<\/p>\n<p><strong>NESS is your ideal partner for all these issues.
