Blowdown valve(s) must be full size of the connection on the boiler. Steam boilers 15 psig and below require at least one blowdown valve. Higher-pressure boilers require two blowdown valves with one or both valves being slow opening type. Each water column and float type low water cut-off must be equipped with a blowdown valve.
Boiler design is the process of designing boilers used for various purposes. The main function of a boiler is to heat water for steam generation. Steam produced can be used for a variety of purposes including space heating, sterilization , drying, humidification and power generation.
Aug 08, 2002 · Steam-to-steam humidifiers use a steam coil immersed in a water bath to heat the water to boiling (Fig. 2). The boiling water produces humidification steam at atmospheric pressure.
On December 5, 1988, at 11:45 a.m., boiler steam was released to humidify an electrical components manufacturing plant in Ohio. At noon, employees returning from lunch noticed an odor described as musty, pungent, "ammonia-like," or "radiator-like," and the work area was evacuated.
Adding amines to steam for humidification . Humidity control is required in all health care facilities. Direct injection of steam from a central boiler plant is the most economical humidification system. The steam carries neutralizing amines—corrosion-inhibiting chemicals—that are added to boiler feedwater to prevent pipe corrosion.
While pressurized steam-injection humidifiers leverage the output of an existing boiler or central steam plant, the tradeoff is that boiler chemicals carried by the steam enter the airstream along with the steam. Buildings with processes or occupants requiring steam that is free of chemicals should not use boiler steam for humidification.
May 17, 2018 · The local DriSteem representative, Brian Willemsen of R.L. Kistler, suggested a steam-to-steam humidification system. This system provides chemical-free steam to the space and, because it uses boiler steam as the heat source, it has very low energy costs. There was just one problem: The museum does not have a boiler.
Reimers Electra Steam is a manufacturer of electric steam boilers for a variety of commercial baking equipment applications, such as, proof boxes, ovens, & other food and bakery equipment. Our boilers are used by restaurants, bakeries, and other establishments that engage bakery steamers.
plant steam to the room was discon-netted and a small once-through boiler was installed to provide con-tinuously injected steam humidifica-tion.-This arrangement offered flexibil-ity in varying amine concentrations in the steam. The boiler was operated at 15 psig, and all of the steam was used for humidification. The three FDA-

Nov 14, 2016 · Steam-to-steam humidifier In either case, humidification components are available in a variety of configurations, including single or multiple dispersion tubes or panel/coil type humidifiers that keep humidification steam separate from boiler steam.
6 campus main steam lines and auxiliary plant loads. The #5 boiler supplies 600 psig steam to a pressure-reducing valve that feeds the 200 psig steam header. The 600 psig steam turbine generators were decommissioned and removed after the coal boiler shutdown, and the plant no longer operates turbines for continuous electrical generation.
Sussman Electric Boilers products include electric steam boilers, stainless steel electric steam boiler, electric steam generator, electric steam superheater, electric hot water boiler, humidification generators and steam heat exchangers.
The boiler steam heats the city water through the exchanger and returns it to the boiler. The city water, which has not come in contact with chemical additives, becomes the source of steam for humidification. In this way, steam is used, and there is no increase in energy consumption as with electric units.
Steam Operations Overview. Steam Operations consists of a 20,000-square-foot facility that provides 320,000 lbs/hr of steam for heating, humidification and sterilization connected to four miles of underground and aboveground piping. This is accomplished with four industrial size watertube 80,000 lbs/hr Babcock & Wilcox Boilers,

On the other hand, the water and Legionella comments are puzzling. The subject of the thread is steam humidifiers. Clean steam generators may use clean water (DI is best) as a source, but steam is produced. If that's an issue for microbial growth, then a lot of autoclave mfrs have a problem. My chimps have clean steam.
BOILER STEAM HUMIDIFIERS: Many buildings were originally equipped with steam humidifiers as a byproduct of the traditional boiler room. Fueled by either gas or electricity, water is boiled to provide hot water, heat, and humidity for an entire building. To add humidity, boiler steam is released directly into the air stream.
The flow of steam to the plant. When steam condenses, its volume is dramatically reduced, which results in a localised reduction in pressure. This pressure drop through the system creates the flow of steam through the pipes. The steam generated in the boiler must be conveyed through the pipework to the point where its heat energy is required.
SHU Series Steam Boiler Humidifiers. The Humidity Source SHU Series of steam boiler humidifiers have been designed to provide low pressure (under 15 psig) steam for a multitude of humidification and HVAC requirements. High quality steam is efficiently and quietly generated with minimal generator heat loss to the surroundings. The Humidity
The Humidity Source SHU Series of steam boiler humidifiers have been designed to provide low pressure (under 15 psig) steam for a multitude of humidification and HVAC requirements. High quality steam is efficiently and quietly generated with minimal generator heat loss to the surroundings.
DriSteem offers a full range of systems for steam generation: GTS® (gas-to-steam) humidifiers that are the industry's best-selling gas-fired humidifier, electric steam humidifiers offering endless flexibility anywhere electricity is available, and STS® (steam-to-steam) humidifiers that create chemical-free humidification steam using boiler steam as the energy source.
Nov 14, 2016 · Boiler steam humidifiers (direct injection or steam-to-steam). Steam humidifiers can be used to put steam directly into the duct, air handler or the actual space. Assuming there is an onsite boiler, steam generated from this source can be used for direct dispersion into the duct system/space or as an indirect source for generating humidification steam.
Energy Efficency In Hospitals – The Steam (on photo: San Antonio Community Hospital – Cogeneration plant) Furthermore, steam installations are relatively easy to regulate. Steam is used for many applications in hospitals, including sterilisation, humidification, heating and providing hot tap water.

creating very pure humidification steam. Instead of injecting boiler-generated steam directly into the airstream, boiler steam is used as an energy source to heat a second pressurized vessel filled with deionized water, creating ultra-pure steam for humidification. This system offers flexible design, easy installation
The boiler tubes in the watertube design carry the heated water inside the tubes between the lower drum (mud drum) and upper drums (steam drum), with the generated steam accumulating in the upper drum. Heat is generated in the furnace area and transferred to the water through two main zones,
Jan 26, 2017 · If we select a steam-to-water heat exchanger—also called a convertor—at 30 PSIG entering steam pressure, we get a shorter unit than if we select it at 5 PSIG entering steam. There's slightly more latent heat in higher pressure steam, but the overriding factor comes from the steam temperature. 30 PSIG steam is 274°F while the 5 PSIG steam is 227°F.
Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
Boiler Feed Pump Control Using Variable Frequency Drive. 2016-5-19 · 2. BOILER FEED PUMP (BFP) A boiler feed water pump is a specific type of pump used to pump feed water into a steam boiler. Boiler feed pump is used to feed water to steam generator boiler drum at desired pressure and temperature.
