High-pressure ammonia water smokeless coal charging
Thread Content
When using smokeless coal loading, should the rising pipe cover be closed first, or should the high-pressure ammonia solution be released first? Who has the operating procedures for this?
If it is done manually, it is recommended to close the rising tube cover first
Of course, the lid should be closed first; otherwise, the oxygen content in the gas will become excessively high
Here’s a link for you to take a look; remember to give me +++ points, haha: http://www.bbscoke.com/read-htm-tid-11692-fpage-8.html
It’s a simple question: the advice on the 3rd floor is meant for you; it represents the minimum requirement for standard operating procedures
If a cover is put on first, a lot of water from the water seal groove will splash out, which is very dangerous for the operators.
I think it’s also necessary to seal it first; otherwise, a large amount of air will be drawn in, resulting in an oxygen level that is too high. This can cause the electrostatic precipitator to trip, and it can also lead to the formation of explosive gases. But in practice here, we first start with high-pressure ammonia water. The reason is the same as that in the comment on floor 6.
The lids in our company are those used by the operators who work on the top of the furnace to close it in order to cool it down. They all wear flame-retardant clothing and masks, and of course they operate with great care, not closing the lid too forcefully so that as little splashing as possible occurs.
