Oil pre-mix burner

摘要

The oil premix burner has a fuel element (1), a burner surface, a distribution chamber (2) below the burner surface, a central oil injector (3), a combustion air duct (4) and an air heat exchanger for preheating the combustion air in the burner surface. The air heat exchanger has multiple double pipe elements (5) over the periphery with an inner pipe (6) and an outer pipe (7) in each case. The inner pipe and the outer pipe of a double pipe element are arranged eccentrically into one another in each case.
