| Abstract: | Directing against the problems resulted from mixedly burning brown coal in large proportion for the low rank bituminous coal fired 1 025 t/h boiler in Hunjiang Power Generation Co Ltd,a mid-temperature flue gas inerting and drying system was additionally installed in the coal pulverizing sytsem,a temperature-regulating air system was installed in the hot air transporting pulverized coal system,and a nitrogen blanketing system was installed in the pulverized coal bunker,and the pulverized coal burners with two channels were retrofitled into honrizontal dense and thin burners.After retrofitting,according to proportion of 50% to burn brown coal,the operation of boiler is safe and stable,the fuel expenses can be saved by 5.436 million yuan in one year,boasting remarkable economic benefit. |
| Keywords: | coal-fired boiler low rank bituminous coal mixedly burning brown coal coal puvlerizing system explosion prevention |
