Coordination issues in the air-water system of dual-fluid nozzles?
Thread Content
I have worked on a flue gas circulating fluidized bed desulfurization project, in which BETE company’s dual-flow nozzles were used. The designed flow rate for these nozzles was 17.6 t/h; the centrifugal pump had a capacity of Q = 25 t/h and a head of 72 m. The nozzles were designed to operate at an air supply pressure of 0.4 MPa, while the maximum operating pressure allowed by the manufacturer for these nozzles was 0.5 MPa. In actual operation on site, however, the pressure reached only 0.43 MPa. Since pressure has a significant impact on the flow rate with these nozzles, the actual maximum flow rate achieved was only 13 t/h. I would like to ask everyone how to increase nozzle flow rate?
Conduct a pressure reduction test and see how the results are
Could we consider changing the nozzle diameter?
What is the actual air pressure? \"The designed flow rate is 17.6 t/h; the manufacturer states that the maximum water pressure that can be achieved is 0.5 MPa, but the actual water pressure reaches only 0.43 MPa. As a result, the maximum flow rate during actual operation is 13 t/h.\" It shouldn’t differ by so much, right?
