Small scale live steam frequently asked questions.
2011/7/5 · Some locos have blowdown valves which can be used to refill the boiler by vacuum: as the boiler cools, the condensing steam inside creates a vacuum which will draw water from a refill hose. Given the ability to refuel and replenish the boiler, you may run the loco virtually indefinitely with occasional service stops.Get Price

Mcdonnell & Miller Low Water Cutoffs - Taco Low Water Cutoffs - Hydrolevel Low Water Cutoffs …
A low water cutoff is a device that detects when the fluid level in hot water and steam boilers drops below the minimum safe operating level specified by the boiler manufacturer. If this should occur, the low water cutoff will cut-off the burner and shut down the boiler. If a boiler is "dry-fired" (burned without water in it), it can result in boiler failure, or a possible fire/explosion. The Get Price
What is Descaling? - Definition from Corrosionpedia
2015/4/23 · A descaling agent or chemical descaler is used to remove limescale from metal surfaces in contact with hot water, such as in boilers, water heaters and kettles. Descaling agents are typically acidic compounds such as hydrochloric acid that react with the alkaline carbonate compounds present in the scale, producing carbon dioxide gas and a soluble salt.Get Price
