Side opening ice melting pipeline and ice melting method

Disclosed are a side opening ice melting pipeline and ice melting method. Laying paths of an original upper blow-off pipe and an original lower blow-off pipe on a marine boiler are changed, the broadside outlet end of the upper blow-off pipe is arranged on one side of a deck water falling broadside discharge port, and the broadside outlet end of the lower blow-off pipe is arranged on one side of a seawater discharge port; the high-temperature waste water in the marine boiler is used for dissolving ice at the deck water falling broadside discharge port and the seawater discharge port, the ship broadside port can be prevented from being frozen, the problem that the deck water falling port or the seawater discharge port is frozen is effectively solved, heat energy of the waste water in the marine boiler can be fully utilized, and the energy-saving effect is achieved. And sewage in the marine boiler can be smoothly discharged out of the ship, so that the water quality in the boiler is kept. 本发明公开了一种舷侧开口融冰管路及融冰方法，
