PURPOSE: A liquid heating device using heat-exchange with combustion gas bubbles is provided to improve a heat transfer rate by minimizing the size of bubbles and maximizing the amount of bubbles. CONSTITUTION: A liquid heating device(100) using heat-exchange with combustion gas bubbles comprises a liquid tank(110), a combustion chamber(120), and a feeding line. The liquid tank accepts liquid(10), such as a heating medium and has a liquid inflow passage and a liquid outflow passage. The combustion chamber is installed inside the liquid tank, and the walls of the combustion chamber form an inner space isolated from outside. The feeding line passes through the walls and supplies fuel and oxygen to the combustion chamber in order to burn fuel. |
