Abstract: Based on the characteristics of the conventional submerged combustion technology,we do some improvement and innovation,and then develop the pressurized submerged combustion vaporization (PSCV) equipment.Basic theoretical calculations of the higher pressure burner are carried out,which agree well with the results from numerical simulation of the high pressure combustion.It will offer appropriate measures for the application and optimization of the high pressure burner in the PSCV system and guidance on engineering design.Besides the advantages of the traditional submerged combustion technology,the pressurized submerged combustion technology is able to utilize the higher pressure exhaust gas.This innovation could further help the system increase efficiency,reduce emission and lower costs,and it will have brilliant future and be widely used in the industrial waste water treatment,oil field and chemistry industry.
