| Abstract: | According to the existing problems of fly ash filter for dry ash removing,a filter with inner cyclone is developed and applied successfully.The results show that the pressure drop of the filter reduces remarkably,the pressure drop of the cyclone can meet the requirements of the system,the life of the ceramic candles can be lengthened,and the scheme can reduce the plant shutdown because of the filter fault.Also,it bring direct economic benefit about 17.09 million CNY per year and the total indirect economic benefit over 50 million CNY. |
