Embodiment

[0015] See attached figure 1 As shown, the boiler shell (1) wraps all the main heat exchange equipment inside, and is insulated with thermal insulation materials. The outer combustion chamber (2) and the combustion chamber (3) are water jackets. 2) It forms a furnace (12) with the combustion chamber (3). The combustion chamber (3) mainly conducts radiation heat exchange. A burner (13) is installed in the middle of the front of the furnace (12). The upper rear position is provided with a furnace hot flue gas outlet (14), and the upper drum (4) is set on the top of the boiler, passing through the right water pipe row (5), the right flue water pipe row (6), the middle water pipe row (7), The left flue water pipe row (8), the left water pipe row (9) and other five drainage pipes are connected to the combustion outdoor bladder (2), and the right water pipe row (5), the right flue water pipe row (6), and the middle water pipe row (7) ) Forms the return flue (10), which is composed of...
