電鍋爐分類及用途： </p> <p> <br /> </p> <p> 此類鍋爐又分為直熱式電鍋爐和蓄熱式電鍋爐兩種，直熱式電鍋爐顧名思義在這里就不再多解釋了，蓄熱式電鍋爐是根據(jù)電力部門鼓勵(lì)在低谷時(shí)段用電加熱，并享受優(yōu)惠電價(jià)的政策，推出的一種新型、高效節(jié)能電加熱產(chǎn)品。蓄熱式電鍋爐配以蓄熱水箱及附屬設(shè)備即構(gòu)成蓄熱式電鍋爐系統(tǒng)，利用蓄熱水箱中的熱水采暖，從成達(dá)到全部使用低谷電力或部分低谷電力的目地。 </p> <p> 電蒸汽鍋爐就也稱電蒸汽爐，電蒸汽鍋爐是指利用電源來(lái)加熱并且產(chǎn)生額定壓力的蒸汽鍋爐。電蒸汽鍋爐可用于紡織、印染、造紙、食品、橡膠、塑料、化工、醫(yī)藥、鋼鐵、冶金等工業(yè)產(chǎn)品加工工藝過(guò)程所需蒸汽，并可供企業(yè)、**、賓館、學(xué)校、餐飲、服務(wù)性等行業(yè)的取暖、洗浴、空調(diào)及生活熱水。 </p>

對(duì)于棱形容器DT=4×截面積÷截面周長(zhǎng);ΛΞ――煤與容器壁間的摩擦系數(shù);ka――煤體的側(cè)壓力系數(shù);h――煤層高度。通過(guò)離散方法，依次計(jì)算出煤斗各截面(截面距Ρ)處的Pv值。根據(jù)虎克定律，煤斗壁與煤體間的摩擦力正比于兩者之間的垂直作用力Pn=Phcos5=kaPvcos5(5為煤斗壁的切面與鉛垂線的夾角;長(zhǎng)四棱臺(tái)處取Pn比較大的壁面分析)。楔形拱原煤經(jīng)碎煤機(jī)處理后，比較大顆粒直徑達(dá)80~100mm，在煤倉(cāng)中堆積，表面產(chǎn)生滲流，小顆粒煤沉在下部，大顆粒煤塊有聚集在一起的可能，依煤倉(cāng)上煤情況而呈間歇的大顆粒層。所以楔形拱的出現(xiàn)是可能的，**易出現(xiàn)在通煤截面**小的部位，即煤斗的下部出口處。粘結(jié)粘附拱實(shí)際運(yùn)行表明，此情況是**易引起堵煤的，尤其是雨季，煤易潮濕，煤斗易生銹，煤的粘附力較大，極易粘附于斗壁上，使通流口徑減小，同時(shí)煤體自身也易密實(shí)，團(tuán)塞。氣壓平衡拱某工程的制粉系統(tǒng)為正壓運(yùn)行系統(tǒng)，通過(guò)給煤機(jī)落煤管傳到煤斗下部出口的壓強(qiáng)有1000Pa以上，產(chǎn)生的阻力N=P×S=1000×016×0156=336N(約3412kgf)，所以產(chǎn)生氣壓平衡拱的可能性也很大。加權(quán)分析四種類型的結(jié)拱都與機(jī)組堵煤的成因有關(guān)，依作用的程度給予不同的權(quán)數(shù):壓縮拱7;楔形拱4;粘結(jié)粘附拱10。</p><p> 電鍋爐是以電力為能源，利用電阻發(fā)熱或電磁感應(yīng)發(fā)熱，通過(guò)鍋爐的換熱部位把熱媒水或有機(jī)熱載體(導(dǎo)熱油)加熱到一定參數(shù)(溫度、壓力)時(shí)，向外輸出具有額定工質(zhì)的一種熱能機(jī)械設(shè)備。***修訂頒布的《特種設(shè)備安全監(jiān)察條例》中鍋爐的定義:鍋爐，是指利用各種燃料、電或者其他能源，將所盛裝的液體加熱到一定的參數(shù)，并承載一定壓力的密閉設(shè)備，其范圍規(guī)定為容積大于或者等于30L的承壓蒸汽鍋爐;出口水壓大于或者等于0.1MPa(表壓)，且額定功率大于或者等于0.1MW的承壓熱水鍋爐、有機(jī)熱載體鍋爐。也就是說(shuō)，無(wú)論使用什么燃料，其規(guī)定范圍都是一樣的，只是燃料熱源不同。電鍋爐必須同樣遵循《特種設(shè)備安全監(jiān)察條例》的規(guī)定。 </p> <p> 對(duì)于容積大于等于30L的蒸汽鍋爐，使用者必須到當(dāng)?shù)刭|(zhì)量技術(shù)監(jiān)督局登記辦理鍋爐使用證，而且每年要接受使用證的年檢。 </p> <p> 對(duì)于容積小于30L的蒸汽鍋爐，我們習(xí)慣稱之為免檢型小型蒸汽鍋爐(也稱蒸汽發(fā)生器)，不需要辦理使用證。對(duì)于常壓的熱水鍋爐，無(wú)論容積是多大的，都不需要辦理鍋爐使用證。和田電壁掛爐哪家比較好。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
