        兩段式煤氣發生爐
        兩段式煤氣發生爐

          兩段式煤氣發生爐有上下兩個煤氣出口,可輸送不同熱值的煤氣,其氣化效率和綜合熱效率均比單段爐高,煤炭經過爐內上段徹底干餾,下段煤氣基本不含焦油,上端煤氣含有少量輕質焦油,不易堵塞管道,兩段爐煤氣熱值高而且穩定,操作彈性大,自動化程度高,勞動程度低。兩端爐煤氣站不污染環境,節水顯著,占地面積小,長期運行成本低。該爐型中爐柵轉動及加煤部分可根據用戶不同需求采用機械或液壓,爐柵為耐熱鑄鋼,其透氣性效果佳,適用煙煤氣化工藝。


          Two-stage coal gasifier contains an upper and a lower coal gas outlet which can put out gas of different calorie value, its gasification efficiency and comprehensive thermal efficiency are higher than that of single-stage gasifier, the coal is retorted inside the upper section thoroughly, the coal gas from the lower outlet almost contains no tar and the gas from the upper outlet contains a little amount of light tar which will not block the pipe easily, the two-stage coal gasifier is of high calorie value, good stability, big operating elasticity, high automation, low labor intensity, no pollution, outstanding water saving, little occupying area and low operation cost. The rotation of the ash grate and coal-feeding parts can be adopted by mechanical or hydraulic ways as per customer's requests.The ash grate is made of heatproof cast iron with perfect ventilation and available for the soft coal gasification.
