manufacturing plant, self-procured nozzles were used to spray steam and urea solution into exhaust gases for <span style=\"font-weight:bold;font-size: 1rem\">Selective Non-Catalytic Reduction (SNCR)<\/span>*.<br \/>\n*Selective Non-Catalytic Reduction (SNCR): a process designed to prevent air pollution caused by nitrogen oxides (NOx) by spraying a reducing agent, such as urea solution or ammonia gas, directly into an incinerator without using a catalyst to chemically reduce nitrogen oxides (NOx) to nitrogen (N2) and water (H2O).<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">\nHowever, the nozzles they used at the time produced spray droplets with uneven sizes, causing non-evaporated coarse droplets to adhere to the inner walls of the incinerator. This caused corrosion of refractory materials, such as bricks and mortar. Furthermore, nozzle clogging caused by urea crystallization was also a recurring problem. To resolve these challenges, the plant consulted us for a solution.<\/p>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<\/div>\n<p><!-- Proposals from IKEUCHI\u3000\u2605p\uff5e\/p\u3067\u6bb5\u843d\u533a\u5207\u308a \u2605\u753b\u50cfURL\u3092\u201d\u3053\u3053\u306bURL\"\u306e\u4f4d\u7f6e\u306b\u5165\u308c\u308b\u3002\u753b\u50cf\u30b5\u30a4\u30ba\u306f\u5143\u548c\u6587HTML\u53c2\u8003\u3000--><\/p>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-bottom:0.8rem;background:url(https:\/\/www.dry-fog.com\/jp\/wp-content\/uploads\/sites\/2\/2024\/10\/10px-45px.svg) no-repeat 0 0;background-size:auto 30px;padding-left: 20px\">\n<h3 style=\"font-size: 1.5rem\">Proposals from IKEUCHI<\/h3>\n<\/div>\n<ul style=\"list-style-type: disc;margin-left:2.8rem;font-size: 1rem;line-height:1.6rem\">\n<div style=\"margin-bottom:0.8rem\">\n<li>Proposed the SETOJet-R Series, an <a href=\"https:\/\/www.dry-fog.com\/en\/projects-technology\/technical-report\/basics-011\/\" style=\"color: #00a273\" target=\"_blank\" rel=\"noopener\">external mixing type<\/a> that is <span style=\"font-weight:bold;font-size: 1rem\">clog-resistant and delivers excellent atomization performance<\/span>, as the optimal choice for urea solution spraying.\n<\/li>\n<\/div>\n<div style=\"margin-bottom:0.8rem\">\n<li>\nUsing the nozzle&#8217;s flow rate diagram, we effectively demonstrated <span style=\"font-weight:bold;font-size: 1rem\">the absence of coarse droplets<\/span>, ensuring the customer\u2019s confidence in the benefits of <span style=\"font-weight:bold;font-size: 1rem\">complete evaporation<\/span> of the urea solution within the furnace\u2014which <span style=\"font-weight:bold;font-size: 1rem\">reduces adhesion to and corrosion of the inner walls while optimizing the reduction efficiency of nitrogen oxides (NOx)<\/span>.\n<\/li>\n<\/div>\n<div style=\"margin-bottom:0.8rem\">\n<li>\nPresented our extensive track record in similar applications for plant engineering companies, providing reassurance to the customer.<\/li>\n<\/div>\n<\/ul>\n<p><!-- \u753b\u50cf\u3000\u2605\u753b\u50cfURL\u3092\u201d\u3053\u3053\u306bURL\"\u306e\u4f4d\u7f6e\u306b\u5165\u308c\u308b\u3002\u4ee5\u4e0b\uff12\u3064\u306e\u3046\u3061\u3069\u3063\u3061\u304b\u3000--><br \/>\n<img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2025\/03\/setojet_1.jpg\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/><\/p>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<\/div>\n<p><!-- Benefits Achieved\u3000\u2605\u672c\u6587\u6bb5\u843d\u3068\u7b87\u6761\u66f8\u304d\u3000--><\/p>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-bottom:0.8rem;background:url(https:\/\/www.dry-fog.com\/jp\/wp-content\/uploads\/sites\/2\/2024\/10\/10px-45px.svg) no-repeat 0 0;background-size:auto 30px;padding-left: 20px\">\n<h3 style=\"font-size: 1.5rem\">Benefits Achieved<\/h3>\n<\/div>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">First, a test conducted in one of the furnaces demonstrated <span style=\"font-weight:bold;font-size: 1rem\">improvements in the corrosion of bricks and mortar<\/span>.
