Although the submerged combustion apparatus has a very high thermal efficiency, the pressure drop is not small. Therefore, a new haet exchanger with direct contact of combustion gas and liquid using spray quenching has been developed for the reduction of this high pressure drop. It was found to be possible to maintain a very high thermal efficiency with 1/10 of the usual pressure drop. The effect of mixing on the volumetric heat transfer coefficient was influenced by the number and diameter of supplied water tubes. The empirical equation for the volumetric heat transfer coefficient was obtained from experimental data.
