Boiler Systems Operation. In steam heating systems, a boiler furnace heats water by means of a gas or oil-fired burner and turns it into steam. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again.
The steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers, they are inherently less efficient than their hot-water cousins and are more finicky to operate.

The potential to use biomass as a low-cost fuel that reduces carbon footprint is growing. The equipment options for firing biomass to replace fossil fuel in plant operations are equally vast. Most types of organic material can be burned for steam and power. In the final analysis, the choice of
This is the most common form of steam actually experienced by most plants. When steam is generated using a boiler, it usually contains wetness from non-vaporized water molecules that are carried over into the distributed steam. Even the best boilers may discharge steam containing 3% to 5% wetness.
When steam is generated using a boiler, it usually contains wetness from non-vaporized water molecules that are carried over into the distributed steam. Even the best boilers may discharge steam containing 3% to 5% wetness.
Another alternative for facilities with low steam requirements is the use of condensing boilers for domestic water heating and building heating. These boilers can operate at up to 98% efficiency compared to around 83% approximate efficiency for steam boilers.
Coil-type steam generators provide an average of six Btu per sq ft per F, which translates to a heating surface requirement of approximately 1.67 sq ft to produce one boiler horsepower (bhp).
