生物質熱風爐缺水的解決方法

生物質熱風爐運行必須保持正常水位。當水位低於最低安全水位線時，稱為缺水事故。缺水事故可分為輕微缺水和嚴重缺水兩種。如水位在最低安全水位線以下，但還能看見，或雖然已看不見水位，但對允許采用“叫水法”成都收賬生物質熱風爐進行“叫水”後水位很快出現時，屬於輕微缺水。如水位已看不見，用“叫水法”也不能出現時，屬於嚴重缺水。
The operation of biomass hot blast stove must maintain normal water level. When the water level is lower than the minimum safe water level line, it is called water shortage accident. Water shortage accidents can be divided into two types: slight water shortage and serious water shortage. If the water level is below the lowest safe water level, but it can still be seen, or although the water level has not been seen, but the water level is slightly short when the water level appears soon after the biomass hot blast stove which is allowed to use the "water-calling method". If the water level is out of sight, when the "water law" is not available, it is a serious shortage of water.
生物質熱風爐缺水事故，如果處理不當，會造成設備嚴重損壞，如果在生物質熱風爐嚴重缺水成都找人公司情況下進水，就會導致生物質熱風爐爆炸。這是因為生物質熱風爐缺水後，一方面鋼板被幹燒而過熱，甚至燒紅，使強度大為下降，另一方面由於過熱後成都收賬鋼板溫度與給水收賬溫度相差極為懸殊，鋼板先接觸水成都找人公司部位因遇冷急劇收縮而龜裂，在蒸汽壓力的作用下，龜裂處隨即撕成大的破口。汽水從破口噴射出來，即造成爆炸事故。
If the water shortage accident of biomass hot blast stove is not handled properly, it will cause serious damage to the equipment. If the water is fed into the biomass hot blast stove in the case of serious water shortage, it will lead to the explosion of biomass hot blast stove. This is because after the shortage of water in the biomass hot blast stove, on the one hand, the steel plate is dried and overheated, or even burned red, so that the strength decreases greatly. On 彩色沥清地坪the other hand, because the temperature of the overheated steel plate is very different from the temperature of the feed water, the place where the steel plate first contacts the water cracks because of the sharp contraction of the cold. Under the action of the steam pressure, the cracks are located at the place where the steel plate first contacts the water. And then ripped into a big breach. Steam water ejected from the breach is an explosion accident.
下面說下具體情況：
Below is the specific situation:
(l)生物質熱風爐缺水現象
(L) water shortage in biomass hot stove
1)鍋內的水位低於最低安全水位或水位計內看不見水位，水位計的顏色發白或發亮。低水位信號報警，信號燈亮起。
1) The water level in the pot is below the lowest safe water level or invisible in the water level gauge. The color of the water level gauge is white or shiny. Low water level signal alarm, signal light on.
2)有過熱器的生物質熱風爐，過熱蒸汽的溫度不正常地升高，發出超溫報警信號。
2) The biomass hot blast stove with superheater, the temperature of superheated steam rises abnormally, and sends out the alarm signal of overtemperature.
3)生物質熱風爐排嫻溫度異常升高。
3) the temperature of biomass hot blast stove is extremely high.
4)給水流破與蒸汽流址異常。一般情況下是給水流瀲小於蒸汽流量，如若有管子或省煤器等發生泄漏時，給水傲雖然增大仍不能維持正常水位，這時給水盈將大於蒸汽流盛。
4) breaking the water flow and abnormal steam flow. Generally speaking, the feed water weir is less than the steam flow rate. If there is leakage of pipes or economizers, the feed water pride can not maintain the normal water level even though it increases, then the feed water surge will be larger than the steam flow.
5)生物質成都找人公司嚴訊缺水時，可以嗅到焦糊味。
5) when the biomass hot stove is short of water, it can smell burnt.
(2)生物質成都***缺水的原因
(2) reasons for water shortage of biomass hot stove
1)司爐人員違反勞動紀律．撤離職守或疏忽大意，對水位的監視不夠。當生物質成都***負荷增大時調整不及時或錯誤操作。水位報警及聯鎖保護裝置已失靈未能及時察覺。
1) the stoker staff violated labor discipline, evacuated from duty or negligence, and did not monitor enough water level. When the biomass hot stove load increases, the adjustment is not timely or erroneous operation. The water level alarm and interlock protection devices have failed to detect in time.
2)司爐人員操作技術水平較低，對水位的判斷失誤。例如，對生物質熱風爐負荷發生突然變化時形成的虛假水位不認識，對水位計因安裝不合理或汽水通路堵塞、汽水旋塞開關不到位等原因造成的假水位不會判別，對缺水或滿水分辨不清等。這些因素都會造成司爐人員對水位的誤判斷而導致生物質熱風爐缺水。
2) the technicians of the stoker are relatively low in technical level, and the judgment of the water level is wrong. For example, the false water level formed when the load of biomass hot blast stove suddenly changes is unknown, the false water level caused by unreasonable installation of water level meter or blockage of steam-water passage, inadequate switch of steam-water cock, etc. can not be distinguished, and the water shortage or full water can not be distinguished clearly. All these factors will cause the stoker to misjudge the water level and lead to the lack of water in the biomass hot stove.
3)給水設備或管路發生故障；不能及時向鍋內進水，造成生物質熱風爐缺水，例如給水泵損壞等。
3) Water supply equipment or pipeline malfunction; unable to feed water into the pot in time, resulting in water shortage of biomass hot stove, such as damage to the feed pump.
(3)生物質熱風爐缺水處理方法
(3) water treatment method for biomass hot blast stove
1)先校對各水位計所指示的水位；正確判斷是否缺水。在無法確定缺水還是滿水時，可開啟水位計放水旋塞，若無鍋水流出，表明是缺水事故，否則便是滿水事故。
1) first check the water level indicated by each water level gauge; correctly judge whether there is water shortage. When water shortage or full water is uncertain, the water level gauge discharge cock can be opened. If there is no pot water flowing out, it indicates water shortage accident, otherwise it will be full water accident.
2)對於允許實施叫水操作的小型生物質熱風爐，可以先進行叫水，判斷生物質熱風爐是輕微缺水還是嚴重缺水。這種情況隻適用於水位計的水連通管水孔高於受熱面的最高火界和水容量較大的生物質熱風爐。否則，不能對生物質熱風爐進行叫水，因為它就會延誤對生物質熱風爐缺水事故處理的時間，使事態擴大。
2) For the small biomass hot stove which allows water-calling operation, water can be called first to judge whether the biomass hot stove is slightly short of water or seriously short of water. This situation is only applicable to biomass hot stove with water connecting pipe water hole higher than the maximum fire boundary of heating surface and larger water capacity. Otherwise, we can't call water for biomass hot stove, because it will delay the time to deal with the water shortage accident of biomass hot stove, and make the situation wider.
3)生物質熱風爐輕微缺水時，應減少燃料和送風，減弱燃燒，並且緩慢地向生物質熱風爐進水至正常水位。一般通過調節給水閥的開度和大小，控制進水流速和給水量，註意不要進水過量。在進水過程中要迅速查明缺水的原因（例如給水管、爐管、省煤器管是否漏水或閥門開錯等）：要及時排除，然後檢查生物質熱風爐有無異常情況，經確認正常之後；方可恢復生物質熱風爐運行。
3) When the biomass hot-blast stove is slightly short of water, fuel and air supply should be reduced, combustion should be weakened, and water should be slowly fed into the biom环氧地坪ass hot-blast stove to normal water level. Generally, by adjusting the opening and size of the water supply valve, we can control the inlet flow rate and the amount of water supply, and we should pay attention not to excessive water intake. In the process of water intake, the causes of water shortage (such as leakage of water supply pipes, furnace pipes, economizer pipes or wrong opening of valves, etc.) should be quickly identified. The operation of biomass hot-blast stove can be restored only after the abnormal situation of biomass hot-blast stove is checked and confirmed to be normal.
4)生物質熱風爐嚴重缺水時，必須進行緊急滅火停爐。滅火停爐的操作程序按緊急停爐的方法實施，嚴重缺水時嚴禁向鍋內進水。有的司爐人員在發現生物質熱風爐缺水後，采用多次間斷進水，每次少量補水的辦法來掩蓋生物質熱風爐的缺水事故。這種做法是非常危險的。采用此法如果生物質熱風爐缺水還不太嚴重，則會造成生物質熱風爐漏水。如果生物質熱風爐缺水相當嚴重，則會造成生物質熱風爐爆炸事故。因為鋼板在無水冷卻的情況下幹燒，則壁面的溫度相當高，此時進水將導致過熱的鋼板急劇冷卻，發生龜裂或爆炸。隻有在生物質熱風爐自然通風冷卻且鍋內水溫降至70℃以下時，方可緩慢進水。進水至正常水位後，應對生物質熱風爐進行全面檢查，如無異常情況，才能重新進行點火起動，恢復生物質熱風爐的運行。
4) when the biomass hot stove is seriously short of water, emergency fire and shutdown must be carried out. The operation procedure of fire and shutdown is implemented according to the method of emergency shutdown. Some furnace managers use the method of intermittent water intake and small amount of water replenishment to cover up the water shortage accident of biomass hot stove after discovering the water shortage of biomass hot stove. This approach is very dangerous. With this method, if the biomass hot stove is short of water, it will cause the leakage of water in the biomass hot stove. If the biomass hot stove is short of water, it will cause an explosion of biomass hot blast stove. Because the steel plate burns dry without water cooling, the temperature of the wall is quite high. At this time, the water will cause the superheated steel plate to cool sharply and crack or explode. Only when the biomass hot air stove is naturally ventilated and cooled and the water temperature in the pot drops below 70 C, can the water enter slowly. After entering water to normal water level, the biomass hot blast stove should be inspected comprehensively. If there is no abnormal situation, the ignition can be started again and the operation of the biomass hot blast stove can be restored.
