Boiler is one of the most important machinery systems on the ship. An economic and efficient working of a marine boiler on a ship requires timely maintenance and special care in starting and stopping the boiler.Routine cleanup is extremely helpful in increasing the working life of a marine boiler. In this article we have brought to you one such important procedure – boiler blow down, which has to be performed at a regular interval of times in order to increase the performance of the boiler.
Why Boiler blowdown?
The water which is circulated inside the boiler tubes and drum contains Total Dissolved Solids (TDS) along with other dissolved and undissolved solids. During the steam making process, i.e. when the boiler is in operation, the water is heated and converted into steam. However, these dissolved solids do not evaporate and get separated from water or steam, and they tend to settle at the bottom of the boiler shell due to their weight. This layer will prevent the transfer of heat amid the gases and the water, eventually overheating
