| 摘要 |
<p>The invention concerns a method for heating liquid, comprising the combustion of a combustible fluid and an oxidant fluid in a burner (1), forming a flame, characterised in that it further comprises the combustion of hydrogen, as combustible fluid and oxygen as oxidant fluid, and passing the flame through the cavity (3), a tubular element (5), immersed in the liquid to be heated, said passage being carried out without contact between the flame end the tubular element (5), between a first end of the cavity, where the burner (1) emerges, and a second end of the cavity, open outwards, and directly contacting the liquid to be heated with the flame at the cavity outward opening, thereby providing intense heat exchange.</p> |
