工業用燃煤鍋爐效率計算方法分析及效率標準之訂定

Abstract

隨著京都議定書的簽訂以及能源意識的抬頭，節能減排已成為全球重視的問題，目前台灣僅訂定燃油及燃氣鍋爐效率標準，並未針對燃煤鍋爐訂定效率標準，本研究之目的在訂定工業用水管式燃煤鍋爐效率標準建議值，裝置容量範圍為5t/h至30t/h，並且針對國家標準(CNS2141)鍋爐熱效率計算方法之出入熱法以及熱損失法公式作分析與比較，找出適合現有量測技術的計算方式，配合實測的15座燃煤鍋爐，建立一新參數OT，可利用OT估計鍋爐效率，並利用Visual Basic撰寫一鍋爐效率計算程式，提供更簡便的鍋爐效率計算方式。參考日本、加拿大、英國、西班牙、奧地利及中國的鍋爐效率標準，評估工業用水管式燃煤鍋爐的操作條件建議值，訂定對日後新設鍋爐的效率標準建議值。

The purpose of this study is to establish the boiler efficiency standards for water tube coal-fired boilers. At present, Taiwan only has boiler efficiency standards for liquid fuel-fired and gas-fired boiler, but not for the coal-fired boiler. Compared with the boiler efficiency standards calculation method from Japan, Canada, UK, Spain, Austria and China, the heat lost method is proposed to be the CNS2141 method to calculate the water tube coal-fired boiler efficiency. After measuring fifteen coal-fired boilers, a new standards of efficiency is proposed for new water tube boilers. We set out the operating conditions and recommended efficiency standards for new water tube coal-fired boilers.
