As shown in figures below, the boiler (1) is placed on legs (4). Boiler water below water
line (23) is in the boiler (1) and the door (13). The steam space in the boiler and door is
located above water line (23). On their outsides, door (13) and boiler (1) are clad with a
thermally insulated jacket (25). The flame is observed through aperture (15) located in
the door (13). The burner is attached to the door (13) on mounting plate (14). Water level
gauges (16) are located on boiler (1) and door (13). The flue-gases exit through outlet
(2) at the rear of the boiler (1). On the inside of the door (13), the flue-gases are diverted
into a tube assembly where a partition (24) made of fire-resistant steel prevented the hot
flue-gases to enter the boiler (1) and door (13) above the water line (23).
A portion of the boiler water travels from boiler (1) bottom via pipes (6), (7), (9), (11), and
(12) into the door (13) via the connected vessels principle. The water in door (13) turns
into steam above water level line (23), exits the door (13) through pipes (18) and (20),
enters the boiler (1) steam area above water line (23) and leaves the boiler (1) via the
steam outlet (22). The part (21) below pipe (20), which delivers the steam from the door
(13) into the boiler (1) prevents the steam coming from the door (13) from getting in touch
with the boiler water, thereby preventing it from getting wet.
Pipes (7), (11), (18), and (20) are flanged (5), (10), and (19) for the purpose of making it
possible to open the door (13), and for the removal of deposits from the boiler (1) bottom.
Connections (3) and (8) are provided on the underside of the boiler (1) for draining the
boiler water, and for the removal of deposits from boiler (1) bottom. The solids are in an
ongoing process removed from boiler and door (13) from water surface (23) via pipe (17).
In the case of hot water boilers of such design, a pump (26) to pipe (20) is added thereby
assuring sufficient water flow in and out of the door (13). In addition, a valve (27) makes it
possible to open the boiler door (13) without emptying entire boiler (1). To intensify the
heat exchange in tubes the coiled wire shaped turbulence promoters, turbulators, made
of fireproof steel are placed in boiler tubes.
