What is a Steam Boiler? A steam boiler is a cast iron or steel container that’s designed to convert water into steam for various heating applications or to turn a steam engine. Water is stored in the tank of a steam boiler and it’s heated by natural gas, propane, coal or an electric element. Once the water is converted to steam, it is collected in an empty tank called a dome.
What You Need to Know About Residential Steam Boilers
Most steam boiler systems in homes are either one-pipe or two-pipe systems. One-pipe (or single-pipe) systems use the same pipes to deliver steam to the radiators and to return water to the boiler. The steam rises up and the water falls down through the same pipes.
Contact GE Power for more information on the use of boilers in steam power plants. With GE’s boilers, our customers can burn a wide spectrum of fuels, from high-rank coals to low-rank coal wastes, and from oil and natural gas to opportunity fuels such as petroleum coke, biomass and oil shale.
Boiler Design: Top or Bottom Supported? - Boiler and Pressure

Steam and Condensate Boiler System. In common facility heating applications, the condensate system is at atmospheric pressure and the system is arranged to drain the condensate to a central condensate receiver, or into local smaller receivers that pump the condensate back to the central condensate receiver.
Steam comes off the top of the Steam Main, comes down to the trap along the vertical pipe in the left of the photo, as it is cooled by heat loss from the pipe. This steam trap is therefore acting mostly as a “steam cooler” wasting steam from the Steam Main.
With subcritical and supercritical steam pressures, temperatures and capacities, our top-supported, one- or two-drum designs use challenging fuels in a circulating bed of inert particles to control combustion and emissions. The CFB boiler is ideal for high sulfur and high ash fuels and various waste fuels, wood, biomass, gob and culm.

Boilers heat water, and then distribute hot steam or hot water to rooms through a series of pipes to heat the home. Steam is sent to radiators, while hot water flows to radiators or radiant heating systems. Boilers are fueled by natural gas, heating oil, propane, electricity or a biodiesel-oil blend.
Jun 18, 2015 · The industry is now greatly affected by the fluctuations in gas pricing, so moving forward with the correct boiler is a top concern in the goal to reduce costs. Additionally, some brewers are now promoting a green image, which means low emission, energy- and water-efficient boilers are increasingly more popular.
How to Run a Hot Water Zone Off a Steam Boiler | 2016-11-21
Nov 21, 2016 · Can I run a hot water zone off an existing steam boiler without a heat exchanger? Yes, but there is a limit to how much radiation your steam boiler can support. Manufacturers list two capacity outputs on every steam boiler: the Department of Energy (DOE) capacity, aka the boiler’s gross output, and the boiler’s net capacity.
