During the production process, the flaps on the gas collection pipes of Oven No. 2 were fully open, and the pressure in those gas collection pipes increased further during coal loading, which led to frequent releases of pressure. Once coal loading was completed, the pressure returned to normal. However, Oven No. 1 did not experience such issues – the flaps, coal loading process, and gas collection pipe pressure were all normal. I seek advice from experts; thank you
If the rising pipe is blocked, the pressure in the gas collection pipe won’t be high. It might be that the gas collection pipe is blocked; P. Another possibility is that the flap in the gas collection pipe is not functioning properly. Check it out and see
Is it possible to load coal at the same time and start ammonia production simultaneously?
A situation like this is likely caused by excessively high levels of ammonia at both high and low pressures.
When high-pressure ammonia water is used for coal charging, the volume of gas entering the gas collection duct suddenly increases (including a large amount of air); therefore, it is not sufficient to adjust only the flap in the gas collection duct during coal charging – it is necessary to adjust the blower simultaneously, mainly through methods such as speed control or increased circulation.
Take a look at the mechanical version of the negative pressure pipeline; its opening value is 516359511. Zhu Guangdong’s contact number is 15069044662 – feel free to reach out if you have any questions. I specialize in researching this type of device
Is the tar box in the negative pressure pipeline clogged? This prevents proper flow of ammonia when high pressure is applied during coal loading, and as a result, gas cannot enter the negative pressure pipeline, causing the pressure in the gas collection pipe of the odd-numbered furnace to rise
Try cleaning the gas collection pipe and the tar box, especially the tar at the bottom of the gas collection pipe.
There tends to be sediment at the bottom of the gas collection pipe; clean it out.
Everyone’s suggestions are great; I’ve learned from them.
