全面論述生物質熱風爐啟動注意事項

 

啟動注意事項有以下三大點︰一 在上水過程中應檢查鍋筒、集箱的孔門及各部的閥門、法蘭、堵頭等是否有漏水現象。當發現漏水時應停止上水並進行處理。當水位升至鍋筒水位計的負100毫米處,停止上水。以後水位應不變,若水位有明顯變化,應查明原因予以消除。二 要求整個升溫升壓過程力求平緩、均勻,並在以下各個階段檢查記錄膨脹指示值。

There are three points for attention in the start-up of biomass hot blast stove: First, in the process of water supply, it is necessary to check whether there are leakage phenomena in the pot drum, header orifices, valves, flanges, plugs, etc. When leakage is found, the water should be stopped and treated. When the water level of the hot blast stove rises to the negative 100mm of the drum water level gauge, the water supply is stopped. After that, the water level should remain unchanged. If the water level changes obviously, the reasons should be found out and eliminated.

Secondly, the whole process of temperature and pressure rise should be smooth and uniform, and the expansion indicators should be checked and recorded in the following stages.

上水前、後。鍋筒壓力分別達到0.3-0.4、10.-1.5、2.0、3.9MPA時,檢查膨脹情況,如發現有膨脹不正常時,必須查明原因並消除不正常情況後方可繼續升壓。

Before and after Sheung Shui. When the drum pressure reaches 0.3-0.4, 10. -1.5, 2.0 and 3.9 MPA respectively, check the expansion. If abnormal expansion is found, the cause must be found out and the abnormal situation must be eliminated before the pressure can continue to rise.

三 的並爐應注意

Attention should be paid to the merging of three hot stoves

1 並爐時保持主汽壓力低于蒸汽母管壓力0.05-0.1MPA,若汽壓高于母管壓力時,禁止並爐。

1. Keep the main steam pressure lower than the steam main pipe pressure 0.05-0.1 MPA in parallel furnace. If the steam pressure of hot blast furnace is higher than the main pipe pressure, it is forbidden to combine furnace.

2 並列時蒸汽溫度應低于額定值30.C,保持較低的水位,燃燒穩定,應注意保持汽壓、汽溫等參數,並緩慢增加蒸發量。

When parallel, the steam temperature should be lower than the rated value of 30.C, maintain a lower water level, stable combustion, and pay attention to keeping the parameters of steam pressure and temperature, and slowly increase the evaporation.

3 在並列過程 中,如引起汽機的汽溫急劇下降時或發生蒸汽管道水沖擊時,應立即停止並爐,減弱燃燒,加強 水,待恢復正︰籩匭虜 。

3 In the process of parallel operation, if the steam temperature of the turbine drops sharply or the water shock of the steam pipeline occurs, the furnace should be stopped immediately, the combustion should be weakened, the water should be strengthened, and the parallel operation should be restored to normal.

4 並列後,應對機組進行一次全面檢查,並將點火至並列過程中的主要操作及新發現的問題,記錄在有關的記錄薄內。

After parallel arrangement, the hot blast stove units shall be thoroughly inspected, and the main operation and newly discovered problems during ignition to parallel arrangement shall be recorded in the relevant record book.

5 當給水泵開始供水時關閉再循環用閥門。

5. Close the recirculation valve when the feed pump starts to supply water.
