燃氣壁掛爐工作原理及過程(cheng)
燃(ran)(ran)氣(qi)(qi)壁掛爐主要是通(tong)(tong)過(guo)將(jiang)燃(ran)(ran)氣(qi)(qi)與(yu)空氣(qi)(qi)預(yu)混后點火燃(ran)(ran)燒,通(tong)(tong)過(guo)換熱系統(tong)將(jiang)熱媒(mei)水(或生活(huo)熱水加(jia)(jia)熱),再通(tong)(tong)過(guo)散熱末(mo)端加(jia)(jia)熱空氣(qi)(qi)用以采(cai)暖(nuan)或供(gong)熱的一個過(guo)程。
燃(ran)(ran)(ran)氣(qi)(qi)壁(bi)掛爐(lu)(lu)的(de)工(gong)作過程(cheng)是:在鍋(guo)爐(lu)(lu)待機工(gong)作狀態下,當鍋(guo)爐(lu)(lu)感知(zhi)到有(you)采暖需求時,風(feng)機啟(qi)動,開始(shi)30 秒的(de)“前(qian)吹(chui)掃”,形成燃(ran)(ran)(ran)燒(shao)倉負(fu)壓(ya),空氣(qi)(qi)進入(ru)(ru)燃(ran)(ran)(ran)燒(shao)倉;風(feng)壓(ya)差開關(guan)啟(qi)動,打開燃(ran)(ran)(ran)氣(qi)(qi)電(dian)(dian)(dian)磁閥,燃(ran)(ran)(ran)氣(qi)(qi)進入(ru)(ru)燃(ran)(ran)(ran)燒(shao) 倉與空氣(qi)(qi)預混;循(xun)環水(shui)泵開始(shi)工(gong)作;同時點(dian)火電(dian)(dian)(dian)極(ji)開始(shi)放電(dian)(dian)(dian)形成電(dian)(dian)(dian)弧將(jiang)燃(ran)(ran)(ran)氣(qi)(qi)點(dian)燃(ran)(ran)(ran),燃(ran)(ran)(ran)氣(qi)(qi)燃(ran)(ran)(ran)燒(shao)后(hou)火焰(yan)將(jiang)主換 熱(re)(re)(re)器中(zhong)的(de)鍋(guo)爐(lu)(lu)爐(lu)(lu)水(shui)加熱(re)(re)(re)用(yong)于(yu)熱(re)(re)(re)交(jiao)換,循(xun)環水(shui)泵將(jiang)熱(re)(re)(re)水(shui)送出與二次系統熱(re)(re)(re)交(jiao)換用(yong)于(yu)采暖或供(gong)熱(re)(re)(re)。
點火(huo)后有個探針檢測(ce)到(dao)火(huo)焰的負離子電流(幾微A)給主板(ban),主板(ban)接受到(dao)工作采暖或供熱才能持續。
當有生(sheng)活(huo)(huo)(huo)熱(re)水(shui)需求時,生(sheng)活(huo)(huo)(huo)熱(re)水(shui)流(liu)量開關啟動并切換電磁三通閥,鍋(guo)爐爐水(shui)通過換熱(re)器將生(sheng)活(huo)(huo)(huo)熱(re)水(shui)換熱(re),然后供應(ying)生(sheng)活(huo)(huo)(huo)熱(re)水(shui)。
