常见问题 2020赌博网送彩金 > Frequently Asked Questions
2. Taiguo boiler often inspects the situation of incoming coal to understand the quality of coal and surface moisture; at the same time, it is necessary to check the situation of incoming coal at work, and to judge the different coals burned at different times according to the load of the unit, the powder level of the silo and the speed of the powder feeder To do this, do the corresponding combustion adjustment work in advance. You should often observe the fire and smoke color on site.
3. Strengthen the combustion adjustment. It should be adjusted according to different loads, www.hnstkguolu.com/different coal types, and adjusted according to the low load test report after overhaul. When adjusting the combustion, first of all, run the primary air as much as possible. Leveling, at the same time, to maintain a reasonable number of powder feeders, to maintain centralized combustion, to avoid too low or too high speed of the powder feeder (400t / h furnace kept at 380 ~ 550 rpm, 670t / h furnace kept at 550 ~ 700 rpm), the primary air door of the powder feeder should be closed in time; the secondary air volume should be reasonable, and the oxygen amount can be appropriately increased, but it should be avoided to be too large, and the upper secondary air door of the powder feeder should be stopped in time Off to 10%.
4. When the powder feeder needs to be deactivated, it must be shut down diagonally from top to bottom under normal circumstances. When there is a problem with the lower powder feeder and it needs to be shut down, the air door of the phase should also be closed in time. Do a good job of preventing accidents caused by combustion instability; when combustion cannot be ensured, you must first put in oil to assist combustion.
5. The rich and lean phase supplementary wind can be released automatically, and the temperature of the rich and lean phase burner wall can be appropriately increased and kept at the upper limit for stable operation, but it is necessary to avoid burning the rich and lean phase burner to red.
6. Henan Taiguo boiler pulverizing system should keep running smoothly, the total air pressure should be kept as low as possible, and the air temperature should be kept as high as possible; the coal feeder should be checked frequently to prevent the coal feeder from suddenly The coal is cut off and affects the combustion. When the coal feeder suddenly cuts coal, it is necessary to adjust the total air pressure in a timely manner. At the same time, it is necessary to strengthen the adjustment of the combustion. When starting and stopping the mill, the operation must be stable to avoid large fluctuations in wind pressure at the same time, and at the same time, it must be approved by the supervisor on duty.
7. When the unit lifts and lowers the load, the operation should be cautious and slow, and the amount of suction and supply air should be adjusted in time to keep the oxygen amount running at the optimal value. The furnace negative pressure should not be too large.
8. Prevent the boiler from leaking air, especially at the fire mouth and the bottom of the furnace. When the slag comes out of the furnace, the deputy watchman must be notified and consent obtained.
9. Firmly establish the "safety first" idea, set the relationship between safety and economy, and do not allow fortunate pursuit of fuel saving while ignoring the stability of combustion; when the boiler cannot be operated safely, it must be fueled in time to assist combustion. And confirm that the oil gun is on fire. At the same time, it is strictly forbidden to increase the steam temperature operation by deactivating the lower powder feeder.
10. Study the 25 countermeasures carefully, especially the "Measures to Prevent Boilers from Extinguishing and Blasting", and firmly establish the idea of protecting the main equipment.
