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.
