<p>A vertical circulating combustion boiler with multi-furnace includes at least two vertical furnaces (30). A rotary grate (11) is set in the lower part of each furnace (30). A smoke returning chamber (25) is formed below the rotary grate (11). The flue gas of each furnace (30) is discharged from an exhaust port of the furnace (30), entering into the smoke returning chamber (25) of the next furnace (30), passing through the rotary grate (11), and entering into the next furnace (30) for re-combustion.</p> |
