Where should the brass washout plugs of miniature boilers be installed?

The correct placement of brass washout plugs on miniature boilers is on the bottom part of the boiler. This is essential for effective maintenance and operation. The washout plugs allow for the removal of sediment and other deposits that can accumulate at the bottom of the boiler during operation. Since these deposits can affect the efficiency and safety of the boiler, having the washout plugs positioned at the bottom makes it easier to clean and ensures that any buildup can be adequately flushed out.

Placing them on the top or side of the boiler would not facilitate the removal of sediments that naturally settle at the lowest point. Similarly, situating them near the safety valve would not serve the purpose of sediment removal at all. Overall, the design and functionality of the washout plugs emphasize the importance of accessibility and efficiency, validating their placement on the bottom part of the miniature boiler.
