The answer is simple thermodynamics.<br \/>\n<!--more--><\/p>\n<p style=\"text-align: justify;\">Who hasn&#8217;t already seen this on a gas cylinder: the <strong>famous and notorious ice crust<\/strong> around the propane gas cylinder? It seems to appear out of nowhere and can be a real nuisance. If you don&#8217;t happen to have a reserve cylinder at the ready, or if you don&#8217;t know a few tricks, you might have to stop your gas supply completely.<\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Why_does_the_ice_crust_form\"><\/span>Why does the ice crust form?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>To put it simply: Because the gas volume required by the gas equipment exceeds the <strong>evaporation capacity<\/strong> of the gas cylinder. Depending on influence factors such as filling level and size of cylinder or ambient temperature, the cylinder sometimes ices over sooner, sometimes later \u2013 in many cases, of course, it doesn&#8217;t ice over at all.<\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"A_fiasco_waiting_to_happen\"><\/span>A fiasco waiting to happen<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>This is what a potential worst-case-scenario would look like: The gas barbecue has an output of 25 kW. This corresponds to a requirement of roughly 1.9 kg\/h LPG. Now, you want to have it running for over an hour on full power with a 5 kg gas cylinder which is almost empty when the temperature outside is low.<\/p>\n<p>If you&#8217;re planning to do this, you should keep the local <strong>pizza delivery number<\/strong> handy, because the gas cylinder is very likely to ice over in a short time.<\/p>\n<figure id=\"attachment_9138\" aria-describedby=\"caption-attachment-9138\" style=\"width: 1024px\" class=\"wp-caption alignnone\"><a ref=\"magnificPopup\" href=\"https:\/\/www.gok-blog.de\/wp-content\/uploads\/2019\/07\/Gasgrill-Schnee-verschneit-Eis.jpg\" target=\"_blank\" rel=\"noopener noreferrer\"><img decoding=\"async\" class=\"wp-image-9138 size-full\" src=\"https:\/\/www.gok-blog.de\/wp-content\/uploads\/2019\/07\/Gasgrill-Schnee-verschneit-Eis.jpg\" alt=\"Wer bei eisigen Temperaturen grillen m\u00f6chte, sollte den Zustand der Flasche besonders im Blick haben und aufpassen, dass diese nicht vereist.\" width=\"1024\" height=\"683\" title=\"\" srcset=\"https:\/\/www.gok-blog.de\/wp-content\/uploads\/2019\/07\/Gasgrill-Schnee-verschneit-Eis.jpg 1024w, https:\/\/www.gok-blog.de\/wp-content\/uploads\/2019\/07\/Gasgrill-Schnee-verschneit-Eis-300x200.jpg 300w, https:\/\/www.gok-blog.de\/wp-content\/uploads\/2019\/07\/Gasgrill-Schnee-verschneit-Eis-768x512.jpg 768w, https:\/\/www.gok-blog.de\/wp-content\/uploads\/2019\/07\/Gasgrill-Schnee-verschneit-Eis-705x470.jpg 705w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption id=\"caption-attachment-9138\" class=\"wp-caption-text\">If you&#8217;re keen to have a barbecue in icy temperatures, you should pay particular attention to the state of the cylinder. <br \/>\u00a9 Rudolf Jaeger GSV<\/figcaption><\/figure>\n<div class=\"en_beitrag_box\">\n<p><span class=\"en_like_h3\">You might also be interested in<\/span><\/p>\n<p>Discover more helpful content on this topic.<\/p>\n<p><a href=\"#weiterfuehrend\">See related posts<\/a><\/p>\n<\/div>\n<h2><span class=\"ez-toc-section\" id=\"How_does_the_cylinder_ice_over\"><\/span>How does the cylinder ice over?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Transforming the liquid propane-butane mixture in the cylinder to the desired gaseous state requires heat. The gas, and therefore the LPG cylinder, cool down when gas is withdrawn. <strong>Heat is taken from the surroundings<\/strong> via the cylinder coat and used to make the gas boil.<\/p>\n<p>The greater the quantity withdrawn from the gas cylinder, the greater the requirement of heat energy. The LPG cools quickly and draws more and more heat from the environment. This first causes the formation of <strong>condensation<\/strong> at the barrier between the gas and the atmosphere, i.e. the gas cylinder.<\/p>\n<p>If the connected gas equipment continues to draw so much gas, the temperature in the LPG drops below 0 degrees Celsius, and so does the outer wall of the cylinder. The water transforms into an ice crust. At some point, the gas can no longer evaporate in the volume required. As a consequence, hardly any gas, or <strong>no more gas whatsoever<\/strong> can be drawn by the device.<\/p>\n<figure id=\"attachment_9142\" aria-describedby=\"caption-attachment-9142\" style=\"width: 1024px\" class=\"wp-caption alignnone\"><a ref=\"magnificPopup\" href=\"https:\/\/www.gok-blog.de\/wp-content\/uploads\/2019\/07\/Flasche-Sonne-Vereisung.jpg\" target=\"_blank\" rel=\"noopener noreferrer\"><img decoding=\"async\" class=\"wp-image-9142 size-full\" src=\"https:\/\/www.gok-blog.de\/wp-content\/uploads\/2019\/07\/Flasche-Sonne-Vereisung.jpg\" alt=\"Selbst wenn die Sonne scheint und das Thermometer \u00fcber 25 Grad Celsius anzeigt, kann es durchaus sein, dass die Gasflasche trotzdem einfriert.\" width=\"1024\" height=\"683\" title=\"\" srcset=\"https:\/\/www.gok-blog.de\/wp-content\/uploads\/2019\/07\/Flasche-Sonne-Vereisung.jpg 1024w, https:\/\/www.gok-blog.de\/wp-content\/uploads\/2019\/07\/Flasche-Sonne-Vereisung-300x200.jpg 300w, https:\/\/www.gok-blog.de\/wp-content\/uploads\/2019\/07\/Flasche-Sonne-Vereisung-768x512.jpg 768w, https:\/\/www.gok-blog.de\/wp-content\/uploads\/2019\/07\/Flasche-Sonne-Vereisung-705x470.jpg 705w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption id=\"caption-attachment-9142\" class=\"wp-caption-text\">Even when the sun is shining and the thermometer is showing above 25 degrees Celsius, it can still be the case that your gas cylinder freezes.<\/figcaption><\/figure>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Countermeasures_Part\"><\/span>Countermeasures Part<strong><br \/>\n<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If you categorically wish to prevent icing, you should always balance the <strong>output of the connected gas equipment<\/strong> with the withdrawal volume of the gas cylinder.
