Analysis of low temperature of reheat steam of a 670t h boiler and corresponding measures 鍋爐再熱蒸汽溫度偏低的原因分析
Somewhat lower temperature phenomenon of main steam has been existing for a long time on boiler on . 5 in datang taiyuan co - generation power 摘要大唐太原第二熱電廠5號(hào)爐長(zhǎng)期以來(lái)存在著主蒸汽溫度偏低現(xiàn)象。
Through analysis of test data in the field , it shows that the main causes leading to said phenomenon for are : adding water - cooling panel in the furnace ; rising of the feed - water temperature ; and somewhat smaller air flow rate in operation 通過(guò)對(duì)其現(xiàn)場(chǎng)測(cè)試數(shù)據(jù)的分析表明,爐內(nèi)增加水冷屏、給水溫度升高以及運(yùn)行風(fēng)量偏小是造成其主蒸汽溫度偏低的主要原因。
The simulations results show that the average combustion temperature is much lower in fuel - rich state and little higher in oxygen - rich state near the best o / f ratio . by extending the post - chamber length the oxidizing gas and the fuel pyrolytic gas can burn completely and the average combustion temperature can be prominently increased . the fuel - rich recirculation zone close to the head of combustion chamber is very important for the combustion 計(jì)算結(jié)果分析表明:發(fā)動(dòng)機(jī)在富燃狀態(tài)下平均燃燒溫度偏低,在接近理想配比的富氧狀態(tài)下平均燃燒溫度有所提高;加長(zhǎng)補(bǔ)燃室可以大幅度提高發(fā)動(dòng)機(jī)的平均燃燒溫度,并促進(jìn)氧化劑氣體和熱解氣體的充分燃燒;燃燒室頭部的富燃回流區(qū)對(duì)發(fā)動(dòng)機(jī)的燃燒非常重要,去掉燃燒室頭部突擴(kuò)段后,氧化劑氣體和燃料熱解氣體不能充分燃燒,發(fā)動(dòng)機(jī)的平均燃燒溫度大幅下降。
