Unlike an open flare, the VCU encloses the flame inside a refractory-lined chamber, holds the gas at oxidation temperature for a controlled residence time, and delivers measurable, repeatable destruction efficiency under audit conditions.<\/p>\n<p>Ever-power VCUs are skid-mounted packages that integrate combustion, fuel-gas, vapour-handling, safety and control hardware into a single delivery. They are designed for marine and truck loading terminals, tank-farm vapour control, gasoline distribution depots, ethanol production and any application where regulators require demonstrable VOC destruction.<\/p>\n<\/div>\n<\/div>\n<h2 style=\"color:#0a3d62;border-left:5px solid #c0392b;padding-left:14px;font-size:26px;margin-top:36px;\">Core Components Explained<\/h2>\n<div style=\"display:grid;grid-template-columns:repeat(auto-fit,minmax(280px,1fr));gap:20px;margin-top:18px;\">\n<div style=\"background:#ffffff;border:1px solid #dee2e6;border-radius:8px;padding:22px;\">\n<h3 style=\"color:#0a3d62;margin:0 0 10px 0;font-size:18px;\">Combustion System<\/h3>\n<ul style=\"padding-left:20px;margin:0;font-size:15px;\">\n<li>Anti-flashback main burner<\/li>\n<li>Continuous-monitored pilot light<\/li>\n<li>Refractory-lined combustion chamber rated 1,400 \u00b0C<\/li>\n<li>Sized for 0.5&ndash;2.0 second residence time at 760&ndash;1,100 \u00b0C<\/li>\n<\/ul>\n<\/div>\n<div style=\"background:#ffffff;border:1px solid #dee2e6;border-radius:8px;padding:22px;\">\n<h3 style=\"color:#0a3d62;margin:0 0 10px 0;font-size:18px;\">Gas Supply Unit<\/h3>\n<ul style=\"padding-left:20px;margin:0;font-size:15px;\">\n<li>Combustion-air blower with VFD<\/li>\n<li>Fuel-gas piping with redundant block-and-bleed<\/li>\n<li>Modulating control dampers<\/li>\n<li>Inlet flow and pressure transmitters with continuous logging<\/li>\n<\/ul>\n<\/div>\n<div style=\"background:#ffffff;border:1px solid #dee2e6;border-radius:8px;padding:22px;\">\n<h3 style=\"color:#0a3d62;margin:0 0 10px 0;font-size:18px;\">Safety Control<\/h3>\n<ul style=\"padding-left:20px;margin:0;font-size:15px;\">\n<li>Detonation\/flame arrestor (FM\/UL listed)<\/li>\n<li>Dual UV\/IR flame detection<\/li>\n<li>Ignition controller with NFPA 86 sequencing<\/li>\n<li>SIL 2 BMS as standard, SIL 3 available<\/li>\n<\/ul>\n<\/div>\n<div style=\"background:#ffffff;border:1px solid #dee2e6;border-radius:8px;padding:22px;\">\n<h3 style=\"color:#0a3d62;margin:0 0 10px 0;font-size:18px;\">Waste Gas Handling<\/h3>\n<ul style=\"padding-left:20px;margin:0;font-size:15px;\">\n<li>Vapour piping with isolation valving<\/li>\n<li>Booster blower (where vapour pressure is insufficient)<\/li>\n<li>Liquid knock-out and demister<\/li>\n<li>Sample point per AS 4323 for performance verification<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<h2 style=\"color:#0a3d62;border-left:5px solid #c0392b;padding-left:14px;font-size:26px;margin-top:36px;\">Performance &amp;
