How to determine the dry steam boiler plant accident occurs when the minimum height of the water level has been less delineated, but still be able to see the water meter water height, sentenced to mild water; when the water meter can not see the water height, sentenced severe water shortages. Finishing conditions such as the following: (1) a conventional water drum height less than the height of the water delineated; (2) a low level warning, automatic alarms sounded, the warning lamp illuminated light; (3) higher temperature superheated steam; (4) supplied conventional water is not less than the vapor flow rate value; (5) increase the exhaust gas temperature. How to determine gas steam boiler water events have occurred gas boilers | oil-fired boilers | steam boiler Environmental Equipment Co., Ltd. has long been below the minimum amount of water when the water level is limited, but the water meter is still also be able to see the water, breaking into a slight less water ; see the water when the water meter, severe dry off. The case of sorting are listed below: (1) lower than the conventional water drum water fraction defined; (2) ultra-low level alarm, the alarm sounds, warning lights; (3) the temperature of superheated steam to improve the water vapor; ( 4) the amount of water supplied is not conventional, less than steam flow; (5) increase the temperature of the flue gas water vapor is discharged.

Boiler reheat steam temperature abnormal phenomenon how to do 1, reheat steam temperature abnormal alarm. 2, when rapid change in the reheat steam temperature, turbine expansion, differential expansion, abnormal vibration or the like changes. 3, frequent accidents significantly reducing water damper action. 4, flue gas damper position is not adjusted properly. Cause 1, the flue gas through the large open shutter adjustment or control failure. 2, Save heated reheater out of adjustment. 3, boiler total wind excessive or too small. 4, furnace wall fouling, coking, fouling, resulting in furnace exit gas temperature is high. 5, reheater heating surface leakage, reheater tubes or burst at the occurrence of secondary combustion. 6, the high side mistakenly turned off after the adjustment is not properly heated Save high, high temperature steam. 7, squib reheat steam pipe. 1 process, or by warm water reheater flue automatic adjustment of the deflector is not normal, it is cut immediately to normal manual adjustment. 2, the case of excessive wind should be timely adjustment of the air volume is normal. 3, if the boiler furnace wall dirt, water wall for soot blowing to respond, if necessary, the main steam temperature can be appropriately reduced. 4. reheater heating surface leakage, the secondary combustion occurs squib or reheater, the result when the reheat steam temperature rises, in addition to quickly take measures to cool, but also processed separately according to the corresponding regulations. 5, sharply decreased 50 deg.] C over 10 minutes temperature reheat steam turbine side, should an emergency stop. 6, if the malfunction is high side, should be immediately shut down, and the next higher vapor temperature adjusted within a predetermined range.

Five kinds of method for detecting water gauge steam boiler water level table is a testament to the steam boiler is safe instruments. Here's to introduce water table is how to steam boiler inspection. Steam boiler water level table index is normal, this question is the key to the safe operation of steam boiler to effective decision-making, so that each of the following safety testing method is particularly important. Water table: Each steam boiler water means at least two tables, it can be used normally, water table conveniently placed for observation and illumination, 6m above the water table during operation from ground level installation of the remote display device. At the same time direct reading water gauges must ensure that the normal use of the water table has the highest indication, a clear sign of the lowest low security level and normal water level (red bar). A lower water gauge visible edge of at least the minimum safe level of less than 25mm, the upper visual edge is at least higher than the safety level zui 25mm, normal water level in the middle of the table. 1, the water table clearly show the normal water level, wash at least once per shift, to prevent false level 2, level 3 Table no leakage, water tables have drainage valves, and have received a place of safety release pipe 4, water table and the drum soda connecting tube with a valve between the boiler must be run when the valve between the inner diameter of the connection pipe soda fully open position 5, the drum water level gauge is not less than 18mm, the diameter of the inner diameter of the flow channel and valve water gauge glass is not less than 8mm. Minimum security level steam boiler tube should be able to ensure reliable water supply to decline. Thus, the population of the downcomer should leave the drum at least 300mm line zui low safety level; the downcomer population waterwall should leave away from the center of the riser number, should be at least two to three times the diameter of the downcomer.
