<p>The boiler comprises a combustion chamber (1) with inlet (4) for combustion air, a burner (3) for gas or liquid fuel (5), a heat exchanger (2) through which the water flows, and an outlet (6) for the combustion products. The burner is arranged above the heat exchanger. The air inlet may be formed by a mixing tube for air and gaseous fuel. The burner may be a flow element with surface combustion, e.g a meshwork screen. The combustion chamber may be enclosed within an air chamber (7) with air inlet (11). The chamber (7) may contain a baffle (8) with blower (9) arranged at an opening (10) therein.</p> |
