WATER HEATING BOILER WITH DIRECT CONTACT

摘要

The water heater (10) has a seating (1) with a first water atomiser (12) in the seating to spray water onto a first heat exchanger array (13) held in the seating by a support (15). A heating gas duct (16) is in communication with an upper part of the a seating. A burner (17) is connected to an upper part of the seating to heat the water in a first reservoir in the seating. A second heat exchange array (21) is spaced from the first by a second support (22). A second sprayer (24) is above the second array. A second water reservoir (25) in the seating is below the first array. A passage (27) allows hot gases to pass from the second array to a position above the reservoir.
