H\u00f6geffektivt sotbl\u00e5sningssystem<\/a><\/h2>\n

Allm\u00e4n installationsprocess<\/p>\n

Nedan beskrivs de \u00e5tg\u00e4rder som kr\u00e4vs f\u00f6r att implementera High Impact Soot System (HISS), f\u00f6r att optimera driften av \u00e5ngsugningsfl\u00e4ktar och \u00e5tervinningspannor.<\/p>\n

\u00a0Steg 1 \u2013 Installera pneumatisk aktuator p\u00e5 \u00e5ngsvavskylarna<\/b><\/h3>\n

Installationen tar cirka 10\u201315 minuter per fl\u00e4kt och kan utf\u00f6ras under pannans drift. Aktuat\u00f6rerna kan kringg\u00e5s med en blockerande pinne.<\/span><\/p>\n

Steg 2 \u2013 Installera pneumatiska kontrollboxar f\u00f6r HISS<\/b><\/h3>\n

Aktuatorn anv\u00e4nds med instrumentluft vid ~6 bar och distribueras till sotbl\u00e5sarna via pneumatiska styrboxar. Varje styrbox kan hantera upp till 12 sotbl\u00e5sare.<\/span><\/p>\n

Steg 3 \u2013 Installera ACABBM 800M-regulatorer f\u00f6r st\u00e4lldonen<\/b><\/h3>\n

Kontakterna f\u00f6r sotbl\u00e5sarna byts ut mot nya med styrning i riktning. Dessutom installeras en ACABBM 800M-styrenhet. Detta utg\u00f6r styrningen f\u00f6r HISS-funktionen.<\/span><\/p>\n

Steg 4 \u2013 Implementering av operat\u00f6rskontrollsk\u00e4rmen<\/b><\/h3>\n

Regleringsdisplayen f\u00f6r sotbl\u00e5saren i DCS \u00e4r det mest kraftfulla verktyget f\u00f6r att ge operat\u00f6rerna m\u00f6jlighet att styra HISS-systemet direkt fr\u00e5n fingertopparna. Regleringsdisplayen \u00e4r skr\u00e4ddarsydd f\u00f6r varje enskild pann och \u00f6kar \u00f6vervakningen av den enskilda sotbl\u00e5sarens drift och status.<\/span><\/p>\n

Steg 5 \u2013 Implementera programvara f\u00f6r procentuell sotutbl\u00e5sning (Soot Power Control)<\/b><\/h3>\n

F\u00f6rdelningen av sotutsl\u00e4ppskapaciteten g\u00f6rs genom att procentandelen per sotutsl\u00e4ppare \u00e4ndras. Programvaran ber\u00e4knar automatiskt antalet startar till och med intervall. Tack vare HISS-tekniken har antalet startar \u00f6kat med 100% samtidigt som operat\u00f6ren f\u00e5r en utm\u00e4rkt \u00f6verblick \u00f6ver det aktuella sotutsl\u00e4ppsprogrammet. Operat\u00f6rerna kan nu snabbt omf\u00f6rdela sotutsl\u00e4ppet till olika delar av pannan beroende p\u00e5 aktuella f\u00f6rh\u00e5llanden.<\/span><\/p>\n

High Impact Sootblowing System General Installation Procedure Below describes the measures necessary for the implementation of the High Impact Soot System (HISS), for the optimization of steam soot blower and recovery boiler operation. \u00a0Step 1 \u2013 Install pneumatic actuator on the steam soot blowers The installation takes approximately 10 \u2013 15 min per blower and can be performed during boiler operation. The actuators can be bypassed with a blocking pin. Step 2 \u2013 Install pneumatic control boxes for HISS The actuators are operated with instrument air at ~6 bar and is distributed to the soot blowers, through pneumatic control boxes. Each control box can handle up to 12 soot blowers. Step 3 \u2013 Install ACABBM 800M controllers for the actuators The contactors for the soot blowers are replaced with new ones, with direction control. Furthermore, an ACABBM 800M controller is installed. This make up the controls for the HISS-function. Step 4 \u2013 Implementation of operator control display The soot blower […]<\/p>\n","protected":false},"author":1,"featured_media":893,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"content-type":"","footnotes":""},"categories":[51],"tags":[],"class_list":["post-888","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-optimized-steam-sootblowing-articles"],"_links":{"self":[{"href":"https:\/\/heatmanage.com\/sv\/wp-json\/wp\/v2\/posts\/888","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/heatmanage.com\/sv\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/heatmanage.com\/sv\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/heatmanage.com\/sv\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/heatmanage.com\/sv\/wp-json\/wp\/v2\/comments?post=888"}],"version-history":[{"count":3,"href":"https:\/\/heatmanage.com\/sv\/wp-json\/wp\/v2\/posts\/888\/revisions"}],"predecessor-version":[{"id":1222,"href":"https:\/\/heatmanage.com\/sv\/wp-json\/wp\/v2\/posts\/888\/revisions\/1222"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/heatmanage.com\/sv\/wp-json\/wp\/v2\/media\/893"}],"wp:attachment":[{"href":"https:\/\/heatmanage.com\/sv\/wp-json\/wp\/v2\/media?parent=888"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/heatmanage.com\/sv\/wp-json\/wp\/v2\/categories?post=888"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/heatmanage.com\/sv\/wp-json\/wp\/v2\/tags?post=888"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
