Question 350Steam Plants - Assistant Engineer

The correct answer is B) feed line. In a boiler steam and water system, the pressure is highest in the feed line. This is because the feed line connects the boiler feed pump to the boiler, and the pump is responsible for increasing the pressure of the water before it enters the boiler. The high pressure in the feed line ensures that the water is forced into the boiler, where it can be converted into steam. The other options are incorrect because the dry pipe, steam stop, and mud drum are not the locations where the pressure is highest in the system. The dry pipe carries the steam from the boiler to the engine, the steam stop controls the flow of steam, and the mud drum is used to collect sediment and impurities from the water.
