Isolated operation of the CFB unit after power failure since the launch of measures
Reduce the amount of flowing of water is too large adverse impact on the unit. Young fire started when a fan make the material flow of the normal level immediately after the wind dropped slightly higher than the flow of the wind to slow the rate of decline in bed temperature, and arrange for staff to return material put shame back to gray material related to the return expected wind damper Room wind pressure (1000 ~ 2000) KPa, put back to gray when the material will return the material to ensure that both the ashes soon exhausted, but also to ensure that cold air can be inhaled materials back to the wind room, because the boiler has just started by Cyclone back down to capture the temperature is very low ash material, bed temperature down quickly, not to feed back into the furnace ash bed temperature can increase more quickly. In addition, while the fan will start adding coal, plus the amount of coal to be slightly higher than the oxygen level during normal operation, if the increase is too low will cause the amount of coal bed temperature continued to decrease, or even fire. The rate of increase as the bed temperature to decide when to stop playing back material gray; (7) If there is failure of auxiliary power system can not immediately fire Yang, need to press the fire, the insulation is very important to do. Quickly cut off when the pressure of the fire main steam valves (including electric and manual valves) and the even rows, will be ranked, sampling valves, fan baffle. Ensure the boiler is not air leakage, no more than water, reduce heat loss, make ready to fire Yang; ( If the engine trip due to full-load rejection will cause the boiler drum, or higher than the safety valve off, this time to think of way to make it back seat as soon as possible to avoid the waste exhaust of a large number of successful Young fire. 3, the use of production practice using this method I plant two successful recovery unit operation. (1) for the first time, two boilers and network operation, due to external failures, two boilers all six trips to the coal, the boiler 2, the first and second fan trip (both frequency motor), Fan did not jump, bed temperature decreased slowly; a group of a boiler, secondary air fan, induced draft fan did not jump, the bed temperature decreased rapidly. Therefore, we decided to use 2 ≠} Yang boiler fire. As described above / l ~, N is completed and network. Specific parameters are load rejection electric load 13300KWh, complete and net extraction 62L emperor steam pressure,[link widoczny dla zalogowanych], main steam temperature decreased to 2.89MPa, 387 ~ (3, with a time 23min. (2) a second time, the main steam cushions pipeline leak, fire two boilers pressure shutdown, and other troubleshooting after 8 hours have passed,[link widoczny dla zalogowanych], when the highest bed temperature 570%,[link widoczny dla zalogowanych], the lowest 485 to 12, opened fire after two diesel generators Yang a successful, shared that when the 1 hour 45 minutes followed by direct wiring to the transmission of the circulating fluidized bed boiler bottom .4 Conclusion material as regenerative energy, a feature that is better than other boiler, so as long as the speed of action, and effective measures , cool, calm and act in harmony, it may be time to recover with the least unit's operation, thereby saving time and create efficiency, this method for circulating fluidized bed unit has certain significance.

According to the implementation of national environmental planning,[link widoczny dla zalogowanych], implementation of international conventions and environmental management and enforcement need to adjust the discharge standard system, increase the emissions control program, improved emission control requirements; 2. Provides pollutant emission monitoring requirements and water pollutant emissions base displacement; 3. Adsorbable organic halogen indicators will be adjusted to force the implementation of the project. Since the date of implementation of this standard, \Standards for existing businesses and new enterprises were proposed requirements for water pollutants emission limits, but July 1, 2011 from all the pulp and paper companies will implement the new standards. At the same time standards of vulnerable to serious water pollution problems in need of special protection measures for the region, has also developed a 'ice discharge limits of pollutants in particular. \ More articles related to topics：
