Submerged combustion vaporizer is indispensable heat exchanger equipment for liquefied natural gas (LNG) receiving terminals
it mainly utilizes water bath system as intermediate media to achieve heat transfer between flue gas and LNG. In this work
an unabridged experimental apparatus is built to study the complex heat transfer characteristics of it. Experimental results reveal some unique fluid dynamic phenomena inside SCV system (local water bath freezes). Meanwhile
the simulated model is established for coupled flow and heat transfer process between two-phase mixture and trans-critical LNG. The influences of inlet LNG pressure
inlet LNG velocity
static water height
flue gas flux on the NG outlet temperature and water bath temperature are analyzed. The outcomes can provide some important guidance to localization design of SCV.
