Abstract

The invention discloses a water supply storage mechanism of a marine boiler. The water supply storage mechanism comprises a hot well. A hot well output pipe is arranged on the hot well, the hot well is connected with a first condensate pipe and a second condensate pipe, the second condensate pipe communicates with the drainage end of a condenser, the water inlet end of the condenser is connected with a condensate input pipe, and the condensate input pipe is connected with a steam supply pipeline. A steam injection pipe capable of injecting steam into the hot well is arranged in the hot well, the steam injection pipe is connected with a steam input pipe outside the hot well, a straight-through stop valve, a temperature adjusting valve and a first stop valve are sequentially arranged on thesteam input pipe in the steam conveying direction, and the steam input pipe is connected to the steam supply pipeline. A temperature sensor is arranged on the hot well. The water supply storage mechanism has the advantages that the temperature of water in the hot well can be effectively controlled, so that the oxygen content is reduced, corrosion of metal equipment of the boiler is reduced, and the service life of the whole boiler is prolonged.

Description

Technical field[0001]The present invention relates to the technical field of marine boilers, in particular to the water supply mechanism of marine boilers.Background technique[0002]Due to space constraints, hot wells are usually used as feedwater storage tanks on ships. The water in the hot well is supplied to the boiler. In the boiler water supply process, it was found that the oxygen content in the water decreases with the increase in temperature, and the oxygen content increases once the temperature of the water decreases. If the boiler feed water has a high oxygen content, it will accelerate metal corrosion and shorten the life of the boiler. However, the water in the current well cannot always be kept at a higher temperature, so the oxygen content of the feed water cannot be well controlled.Summary of the invention[0003]The purpose of the present invention is to provide a water supply storage mechanism for a marine boiler, in which the water temperature can be stably controlled...
