我单位现有容量１ｔ／ｈ及以上的工业锅炉约３５０台，年耗燃煤几十万ｔ，是能源消耗大户。但从１９９４年以来我单位开展工业锅炉监测的情况看，锅炉运行中燃煤浪费较大，主要反映在炉渣含碳量、排烟处空气过剩系数严重超标等，炉渣含碳量最高竟达７０８％，空气过剩系... My existing unit capacity of 1t / h and above about 350 industrial boilers, burning coal hundreds of thousands of tons of annual energy consumption. However, since my unit started to monitor industrial boilers since 1994, there was a large waste of coal in the operation of the boiler, which was mainly reflected in the carbon content of the slag and the excessive air excess coefficient at the smoke exhaust. The carbon content of the slag was as high as 70  8%, excess air system ...
