循環(huán)流化床鍋爐設(shè)計-畢業(yè)論文

1、1循環(huán)流化床鍋爐設(shè)計循環(huán)流化床鍋爐設(shè)計摘要摘要循環(huán)流化床鍋爐是近幾十年發(fā)展起來的一種新型燃燒設(shè)備，其具有燃料適應性廣、有利于環(huán)保、負荷調(diào)節(jié)性好、燃燒熱強度大、爐內(nèi)傳熱能力強等優(yōu)點。所以，其一經(jīng)推出就在世界范圍內(nèi)得到了廣泛的應用。特別是在中國，循環(huán)流化床鍋爐技術(shù)在近幾十年取得了長足的進步。本文系統(tǒng)的闡述了10th循環(huán)流化床的計算和設(shè)計過程，主要包括熱力計算、煙風阻力計算、鍋筒強度計算、鍋爐的結(jié)構(gòu)設(shè)計。通過對循環(huán)流化床方面的英文文獻的翻譯，
