Huali four-nozzle
Thread Content
There is a problem with the domestic Huali four-nozzle dual-burner. Is reduced-load production feasible? After working in this field for so many years, I feel that it’s not as good as the German-style old ones. Is it really necessary to go through all that trouble just for that small increase in conversion rate? Increasing the level of labor intensity so much
It seems there was a post about this stove yesterday as well
I think the same way; simple things are made complicated.
For a coal feeding rate of less than 1,500 tons, multi-nozzle operation is not as effective as single-nozzle operation; however, it’s worth considering which single-nozzle system can handle a daily coal feeding rate of 4,000 tons while achieving a high carbon conversion rate, high effective gas output, and stable operation. Multiple nozzles are suitable for larger scales, and the advantages become more evident as the size increases. Additionally, in the event of a failure in one pair of multi-nozzle burners, it is not feasible to keep those burners in operation; the requirement is that they must not be used for more than two hours! The reason is that the flow plant was damaged.
The world’s largest coal-fired boiler with the highest daily coal consumption at present
There is a fault with one pair of multi-nozzle burners; it is not feasible to have that pair of burners in operation. The requirement is that they must not be used for more than two hours! The reason is that the flow plant was damaged. Then the entire system has to be shut down.
The situation you mentioned could indeed lead to a shutdown of the entire plant, but multi-nozzle systems have another advantage: they allow for seamless furnace switching without any fluctuations.
