Troubleshooting: Condensate Contamination

steam header's steam trap. If you find contamination here, you most likely have boiler carryover occurring. This boiler carryover may either be the cause of the condensate contamination you see or be a result of it. Remember that drip legs off steam headers are there to take out carryover though. 5.

Steam Distribution System - an overview

Recommended velocities are: steam exit from boiler, 12 m/s; exhaust steam, 18−23 m/s; dry saturated steam, 23 −30 m/s; superheated steam 36−48 m/s. Steam should be generated at the highest pressure required by any consumer, plus an addition for pressure drop in the pipeline to the consumer.

How to Destroy a Boiler -- Part 3

As the unit cools, the steam condenses and water level drops, which allows the pressure to drop. If the steam drum vent is not open when the unit is cooling, a vacuum condition can result. A vacuum on a boiler can cause problems with leaks on rolled tube seats of generating tubes, which are designed for a mechanical fit to withstand positive ...

Flash Steam Recovery |

High pressure condensate enters the flash steam generator from the left. A rapid drop in pressure flashes some of the condensate to steam that goes up into the low pressure steam header, and the rest becomes low pressure condensate that flows into a pumping steam trap that returns it to the low pressure condensate return line.

Tips for a Successful Steam Boiler Replacement | U.S

6/14/2018 · Other than the boiler header, you should never pipe a steam riser into the bull (side outlet) of a tee. See Figure 1. Figure 1. A dropped header produces dryer steam. Although a dropped header is not a requirement, dryer steam moves faster, stays in a steam state longer, and has less of a chance for system noise caused by excessive water in ...

Steam/water circulation design

Natural circulation principle is usually implemented on small and medium sized boilers. Typically the pressure drop for a natural circulation boiler is about 5-10 % of the steam pressure in the steam drum and the maximum steam temperature varies from 540 to 560 °C. Natural circulation principle The water/steam circulation begins from

Skid Assemblies

Boiler and ancillaries are mounted onto a steel chequer plate floor and surrounded with box sectional uprights. Main steam is piped to a steam header, which is trapped to the condensate return tank. An optional pressure-reducing valve can be connected to the steam header, and an outlet connection is left for onward connection.

headerpiping - steamheating

If you have two 3” mains, and all of the radiation is still connected to them, a 3” header isn’t going to drop much water out of the steam. The velocity in the header will be twice the velocity in each building steam main. Size the header big. You buy the pipe once, and if it is sized right, the fuel savings of not needing to lift water ...

What is a Drop Header?

The best results are accomplished by "drying" the steam at the header (by increasing the steams "travel" distance at the boiler). That's usually tough to do in a low basement, so a drop header can give you the best of both worlds. Bob Young replies: As Dave pointed out, extra dry steam is a key result and it makes piping a proper header a snap ...

Boiler room steam distribution header

The header pressure should be a constant 125. There's no way you can (or should) have the velocity of steam in the header the same as the steam leads. New headers are often oversized initially anyway, to allow for future additions. This also gives water droplets that have been carried over, out of the boiler, a low velocity area to drop out of ...

Effective Boiler-Level Control

Steam header. Multiple-boiler systems employ a steam manifold usually referred to as the main distribution header (Figure 1). Proper flow to and from a steam header is necessary for efficient warmup, good steam quality, and proper steam distribution. The design of a distribution header should allow boilers to share a load equally.
