The lining material in the target area of fluidized bed boilers suffers severe wear after ammonia water injection for denitration
Thread Content
After adding denitration nozzles to the horizontal flue of the 210t and 240t circulating fluidized bed boilers, the lining material in the separator target area suffered severe wear and detachment. After it was rebuilt using corundum plastic, the tubes cracked due to wear within less than 30 days of operation. Is there any solution?
Increase the number of ammonia spray points to improve nozzle atomization
Are there any pictures? Generally speaking, adding a denitration nozzle has little impact on the casting material of the flue gas separator; could the reason for your problem not be related to the nozzle? ?
To completely resolve environmental issues in circulating fluidized bed boilers, it is necessary to adopt carbon molecular gasification combustion technology to prevent problems at the source. On the condition of meeting environmental standards (excellent standards), environmental protection costs are reduced by over 80% compared to current treatment costs.
It might be due to poor atomization performance of the denitration nozzle, or issues related to its installation

The technological innovations in the vaporized combustion of carbon molecules lie in designing a process with a Ca/S ratio close to 1 for oxygen-deficient sulfur fixation in gas production (with a sulfur removal rate of nearly 100%) and a low excess air ratio of α close to 1 for combustion (with an efficiency of nearly 100%). By reducing the amount of oxygen at the source, it is possible to prevent the formation of chemical pollutants such as SO2, NOX, and VOCs.
