Boiler Inspection

Jun 03, 2006 · Why American boiler makers won't do this is a mystery to me. The first one who produces a good reliable high-efficiency line of residential steamers is going to sell a LOT of boilers. Here in Baltimore, I could probably sell them right off the truck! And don't think converting a steam system to hot-water is without its pitfalls.

Top Ten Boiler and Combustion Safety Issues to Avoid

A boiler explosion is a catastrophic failure of a boiler.There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early boiler explosions.

There are two types of steam boilers. One is the fire tube, which is made from one combustion chamber and many tubes. The hot gases that are produced during the combustion process pass from inside the tubes and make a heat transfer with the water that is on the outside of the tubes. The other type is a water tube steam boiler.

Specific problems can include frequent boiler shutdowns from low-water level, damaged steam pipes and valves due to water hammer, vibration, corrosion, erosion, reduced capacity of steam heaters, and overloaded steam traps. These problems are most frequently caused by low steam quality, often called "wet steam" or "carry-over."
