Abstract
In order to make the superheated steam flowing at high speed complete the desuperheating process in the pipeline with limited distance, so as to save the production cost, this paper makes structural innovation on the existing equipment, a solution to install static mixing elements in the pipeline downstream of the nozzle of the desuperheater is proposed to improve the performance of the desuperheater without increasing the cost of nozzle atomization. Based on Fluent software, the working process of the new desuperheater is numerically simulated, and its working mechanism and desuperheating effect are visually analyzed. Compared with the traditional desuperheater, the desuperheating range of the new desuperheater in the pipeline with the same distance is increased by about 70.8%, and the temperature non-uniformity coefficient is reduced by about 75.5%. Furthermore, the validity of the above simulation results is verified by experiments.
