The main function of a non-return valve (NRV), otherwise known as stop or check valve, is to allow steam flow in one direction, and automatically prevent backflow. In other words, they prevent steam from flowing back to the main header of the boiler, or back to a boiler that has failed or is off-line.

Jul 09, 2018 · Boilers Terminology: If you are connected to steam industry-education or employment or business- then this post is going to deliver a lot of value by adding lots of definitions and terms in your knowledge bank. Today, We are going to list all common terms related to steam process industry and steam boilers plants.
A Steam Trap is an integral part of a steam system. Steam traps play the important role in maintaining the productivity and efficiency of steam system. This exhaustive guide answers all the questions one might have about steam traps, their working principles, troubleshooting etc. What is a steam trap?
A steam trap is an automated device designed to remove condensate from a steam-containing enclosure while retaining live steam at the same time, giving the live steam more surface to maximize heat transfer efficiency. By removing condensate, steam traps allow it to be collected and re-used.
Jun 24, 2014 · Those sensors work well on bucket traps because they cycle full-open to full-closed, but an F&T trap (to me at least) sounds about the same all the time. The only way to check an F&T trap is to open up a valve on the discharge and see what comes out. If the trap is working, you'll get a mixture of water and vapor. If it's not, you'll get steam.

sections of this Code specify the rules by which steam boilers, pressure vessels and connecting piping are to be designed, constructed and installed. Section I of the ASME Code contains rules for Power Boilers which, for the case of steam boilers, are boilers designed for a maximum allowable operating pressure (MAWP) greater than 15 psig.
They tend to run higher steam pressures for this process. And the kettles usually have an F&T trap on the outlets of the kettle jackets. There's one that has the kettle right next to the boiler. Steam goes up and into the kettle and the condensate comes out, into an F&T, and right into the feedwater tank.
If a steam distribution system includes more than 500 traps, a steam trap survey will probably reveal significant steam losses. Operation. Depending on boiler efficiency and steam pressure, low pressure steam requires 1,200 to 1,400 BTUs of input energy to produce 1 pound of steam.

Jun 24, 2014 · This boiler is providing steam for a steam kettle in a commercial kitchen in a school. We installed main vents, a bucket trap for the main return line, and a Float & Thermostatic trap for the kettle. We also installed a condensate-receiving tank since we don't have enough height for the condensate to return to the boiler by gravity alone.
When a steam trap fails, it allows steam to blow-through along with the condensate. This loss of steam can represent a substantial energy loss. A basic component of all industrial energy audits in plants with steam, is a stream trap inspection and repair/replacement program. Operation. There are several types and manufacturers of steam traps.
Inverted Bucket Steam Trap In an inverted bucket steam trap (Figure 1), steam and condensate enter the trap and flow under the bottom of the inverted bucket. As steam collects at the top of the bucket, the bucket rises and closes the discharge valve.
Steam traps should be selected and agreed between the boiler supplier and trap supplier, according to their required duty and should be of cast or forged steel. Steam traps are the most effective and efficient method of draining condensate from a steam distribution system.

The steam trap is designed to close in the presence of steam and drain the condensate. As the steam condenses into a liquid, it gives up its latent heat. The latent heat results in lb, for lb the steam releasing more energy than the water. The steam traps purpose is to prevent the steam leaving the system before it gives up its latent energy

Some steam heating systems may include a hot water or hydronic heat using hot water radiators not steam radiators on the lower floor or basement level when all of those radiators are located below the water level in the steam boiler. How to recognize a Steam Trap: Depending on the application steam traps are sold in a blizzard of forms and

Aug 07, 2017 · Today on this episode of Boiling Point, Ritchie talks with Gerald Blain about the different types of Steam Traps for your steam system. Steam Traps are vital to your steam system has they pull the
Oct 22, 2016 · Condensate from Steam traps Steam Traps are widely employed in Steam distribution network to discharge the condensate from the steam lines as soon as it is formed. This prevents two phase flow in steam lines enabling us in reducing the pressure drop and increasing the life of the pipelines preventing water hammer.
Dec 01, 2011 · What Are Steam Traps? A steam trap is the separation point between the steam system and the condensate system. The purpose of a steam trap is to pass condensate, air and non-condensable gases from the steam system into the condensate system while not allowing live steam to pass into the condensate system.
When high pressure hot condensate is discharged through a steam trap to lower pressure, flash steam is generated. If this flash steam then flows into a return line that contains sub-cooled condensate at a much lower temperature, an instant collapse (condensing) of the flash steam will occur as it gives off its latent heat to the condensate, and

Steam energy savings are achieved through the Delta traps’ unique venturi design. There is TRUE continuous condensate discharge without any open/close cycles rather than intermittent discharge like traditional mechanical type steam traps such as ball float or inverted bucket traps.
Maximum steam efficiency. Maximum energy savings. In a steam-based heating process, condensate (condensed steam) is formed when the steam gives up its latent heat and needs to be removed quickly to maintain heating efficiency. A steam trap is an automatic device (constantly opens, closes or modulates automatically) used to discharge this condensate (and non-c
Steam trap: The function of a steam trap is automatically to drain away or return to the boiler, the water collected in the steam pipe or steam jacket due to partial condensation of steam without allowing steam escape. Feed pump: Feed pump delivers feed water at a pressure higher than that in the boiler. There are two types of feed pumps.

A float-and-thermostat steam trap, if present, is more likely to be found on newer, modern steam heating systems in which the boiler and piping heat up rapidly. The trap is operated (opened or closed) by a float assembly that will drain condensate through the trap without depending on temperature or heat-up time.
Apr 30, 2014 · The benefit gained with a steam trap, is that steam is contained in the heating line until it condenses, thus giving up all of its latent heat. Thermodynamic steam trap use pressure energy of the steam to close the valve which consists of a simple metal disc. The sequence of operation is shown in figure below.
