鍋爐發(fā)展的趨勢主要是：①進一步提高鍋爐和電站熱效率；②降低鍋爐和電站的單位功率的設(shè)備造價；③提高鍋爐機組的運行靈活性和自動化水平；④發(fā)展更多鍋爐品種以適應(yīng)不同的燃料；⑤提高鍋爐機組及其輔助設(shè)備的運行可靠性；⑥減少對環(huán)境的污染。蒸汽發(fā)生器參數(shù)指標(biāo)編輯鍋爐參數(shù)是表示鍋爐性能的主要指標(biāo)，包括鍋爐容量、蒸汽壓力、蒸汽溫度、給水溫度等。鍋爐容量蒸汽發(fā)生器可用額定蒸發(fā)量或大連續(xù)蒸發(fā)量來表示。額定蒸發(fā)量是在規(guī)定的出口壓力、溫度和效率下，單位時間內(nèi)連續(xù)生產(chǎn)的蒸汽量。大連續(xù)蒸發(fā)量是在規(guī)定的出口壓力、溫度下，單位時間內(nèi)能大連續(xù)生產(chǎn)的蒸汽量。蒸發(fā)量的單位習(xí)慣上以噸/時表示，電站鍋爐的容量也可用與之配套的汽輪發(fā)電機的電功率（兆瓦）來表示。蒸汽參數(shù)包括鍋爐的蒸汽壓力和溫度，通常是指過熱器、再熱器出口處的過熱蒸汽壓力和溫度，如沒有過熱器和再熱器，即指鍋爐出口處的飽和蒸汽壓力和溫度。鍋爐壓力單位用兆帕(MPa)表示，也有用工程大氣壓(at)表示的，1兆帕等于。給水溫度指省煤器的進水溫度，無省煤器時即指鍋筒進水溫度。蒸汽發(fā)生器注意事項編輯鍋爐是具有高溫、高壓的熱能設(shè)備，是特種設(shè)備之一，在、事業(yè)企業(yè)及各行各業(yè)使用。塔城電蒸蒸汽發(fā)生器價格吐魯番全自動蒸汽發(fā)生器廠家。</p><div
