This invention discloses a waste heat boiler with integrated bypass function, comprising a waste heat boiler body and an internal flue gas direct passage. The waste heat boiler body is equipped with one or more stages of heat exchange tubes, through which high-temperature flue gas passes, exchanging heat with steam or boiler feedwater within the heat exchange tubes. One or more internal flue gas direct passages replace the external bypass; these passages pass through the middle of the heat exchange tubes; and their opening and closing are controlled by dampers. This invention offers the following advantages: because the flue gas direct passage is surrounded by hot flue gas, low-temperature conditions do not occur even with no flow, eliminating the problem of flue gas dew point corrosion. The waste heat boiler possesses a bypass function compatible with SCR denitrification, ensuring that flue gas emissions meet standards even when one waste heat boiler is switched off for maintenance, guaranteeing long-term stable operation of the unit.
