what is steam distribution system

Full Answer

How does the Steam distribution system work?

The steam distribution system is the essential link between the steam generator and the steam user. This Module will look at methods of carrying steam from a central source to the point of use. The central source might be a boiler house or the discharge from a co-generation plant.

What is the pressure in the Steam distribution system?

The pressure in the steam distribution system is usually between 2 and 12 bar, where steam with a pressure of between 2 and 5 bar is called low-pressure steam, and medium-pressure steam has a pressure of between 9 and 12 bar (SFI, 1990). In the steam distribution system condensate is formed, due to cooling of the steam.

What is steam distribution system?

The steam distribution system transports the steam to the consumers. The pressure in the steam distribution system is usually between 2 and 12 bar, where steam with a pressure of between 2 and 5 bar is called low-pressure steam, and medium-pressure steam has a pressure of between 9 and 12 bar ( SFI, 1990 ). In the steam distribution system condensate is formed, due to cooling of the steam. Steam traps are used to remove the condensate, and these are also used to ventilate the system during start-up and during operation. The steam traps must cope with varying capacity and pressure and close for steam ( Armatec, 2004 ). There are basically two different types of steam traps: thermal and mechanical. The function of the thermal steam traps is based on the temperature difference between saturated steam and condensate that is somewhat cooled. There are several variants, of which capsule steam trap and bimetallic steam trap are two examples. The mechanical steam traps work from the basis that steam and condensate have different densities. A float steam trap is a common mechanical steam trap. To select the right steam trap, account must be taken to the type of installation, the amount of condensate, the pressure, and the temperature. Furthermore, consideration should be given to whether there should be individual drainage or group drainage, and the acceptable level of condensate to be impounded ( Armatec, 2004 ).

How is refinery steam generated?

Steam typically is generated by heaters (furnaces) and boilers combined in one unit. Feedwater supply is an important part of steam generation.

How is steam generated?

Steam is generated in main generation plants, and/or at various process units using heat from flue gas or other sources. Heaters (furnaces) include burners and a combustion air system, the boiler enclosure in which heat transfer takes place, a draft or pressure system to remove flue gas from the furnace, soot blowers, and compressed-air systems that seal openings to prevent the escape of flue gas. Boilers consist of a number of tubes that carry the water–steam mixture through the furnace for maximum heat transfer. These tubes run between steam-distribution drums at the top of the boiler and water-collecting drums at the bottom of the boiler. Steam flows from the steam drum to the superheater before entering the steam-distribution system.

What are some safety features in steam distribution systems?

Safety features aim to minimize the risk of an accident happening. Adhering to safety procedures is essential in making factories with steam distribution systems safer. Here are some safety features each plant should have.

What is Steam's primary service?

Steam's primary service is to allow its users to download games and other software that they have in their virtual software libraries to their local computers as game cache files (GCFs). Initially, Valve was required to be the publisher for these games since they had sole access to the Steam's database and engine, but with the introduction of the Steamworks software development kit (SDK) in May 2008, anyone could potentially become a publisher to Steam, outside of Valve's involvement to curate games on the service.

What happened to Steam?

An attempt occurred in November 2011, when Valve temporarily closed the community forums, citing potential hacking threats to the service. Days later, Valve reported that the hack had compromised one of its customer databases, potentially allowing the perpetrators to access customer information; including encrypted password and credit card details. At that time, Valve was not aware whether the intruders actually accessed this information or discovered the encryption method, but nevertheless warned users to be alert for fraudulent activity.

Why did Valve sue Steam?

Steam's predominance in the gaming market has led to Valve becoming involved in various legal cases. The lack of a formal refund policy led the Australian Competition and Consumer Commission (ACCC) to sue Valve in September 2014 for violating Australian consumer laws that required stores to offer refunds for faulty or broken products. The Commission won the lawsuit in March 2016, though recognizing Valve changed its policy in the interim. The ACCC argued to the court that Valve should be fined 3 million Australian dollars "in order to achieve both specific and general deterrents, and also because of the serious nature of the conduct" prior to their policy changes. Valve argued that from the previous court case that "no finding that Valve's conduct was intended to mislead or deceive consumers", and argued for only a A$ 250,000 fine. In December 2016, the court ruled with the ACCC and fined Valve A$3 million, as well as requiring Valve to include proper language for Australian consumers outlining their rights when purchasing games off Steam. Valve sought to appeal the rulings, arguing in part that they did not have a physical presence in Australia, but these were thrown out by higher courts by December 2017. In January 2018, Valve filed for a "special leave" of the court's decision, appealing to the High Court of Australia, but the High Court dismissed this request, affirming that Valve was still bound by Australian law since it sold products directly to Australian citizens. Later in September 2018, Valve's Steam refund policy was found to be in violation of France's consumer laws, and were fined €147,000 along with requiring Valve to modify their refund policy appropriately.

What is the Discovery Update on Steam?

The September 2014 "Discovery Update" added tools that would allow existing Steam users to be curators for game recommendations, and sorting functions that presented more popular games and recommended games specific to the user , as to allow more games to be introduced on Steam without the need of Steam Greenlight, while providing some means to highlight user-recommended games. This Discovery update was considered successful by Valve, as they reported in March 2015 in seeing increased use of the Steam Storefront and an increase in 18% of sales by revenue from just prior to the update. A second Discovery update was released November 2016, giving users more control over what games they want to see or ignore within the Steam Store, alongside tools for developers and publishers to better customize and present their game within these new users preferences.

When did Steam Greenlight end?

Steam Greenlight was phased out and replaced with Steam Direct in June 2017. With Steam Direct, a developer or publisher wishing to distribute their game on Steam needs only to complete appropriate identification and tax forms for Valve and then pay a recoupable application fee for each game they intend to publish. Once they apply, a developer must wait thirty days before publishing the game as to give Valve the ability to review the game to make sure it is "configured correctly, matches the description provided on the store page, and doesn't contain malicious content".
