最低的環(huán)境溫度<br/>2. 最短的運行周期<br/>3. 最高的運行溫度<br/>4. 加熱介質(zhì)的最大重量（流動介質(zhì)則為最大流量）<br/>第三，電加熱器功率設(shè)計的步驟:<br/>1. 根據(jù)工藝過程，畫出加熱的工藝流程圖（不涉及材料形式及規(guī)格）。<br/>2. 計算工藝過程所需的熱量。<br/>3. 計算系統(tǒng)起動時所需的熱量及時間。<br/>第四，考慮合適的安全系數(shù)，確定加熱器的總功率。<br/>1. 決定發(fā)熱元件的護套材料及功率密度。<br/>2. 決定加熱器的形式尺寸及數(shù)量。<br/>3. 決定加熱器的電源及控制系統(tǒng)。</span></p><p style="line-height: 2em; text-indent:
