Jan 20, 2016 · This massive silver cigar called the feedwater tank holds water before it enters the boiler. The tank can store 100,000 gallons of water heated high above its boiling point to 380 degrees Fahrenheit (193.3 Celsius). To improve efficiency, the plant extracts some of the steam from the water-steam cycle to reheat it. Image credit: GE Power
Part 2: Testing Traps using Temperature. Measuring the trap’s inlet condensate temperature is a first step in the process of testing for steam trap failure. Except in cases of intentional subcooling (such as certain low temperature tracing), the condensate temperature at the trap inlet should be near that of saturated steam.
The “fleet efficiency” or “boiler rating” of a particular boiler brand indicates nothing about boiler quality or boiler durability. In addition, although the fleet efficiency of one brand might exceed that of another, this does not necessarily indicate that any particular model of boiler marketed under the first brand out-performs any
Member Posts: 1,947. If it's partially blocked, you might get boiler flooding as the boiler makes steam and condensate doesn't return as quickly as it should. Level drops, and feeder feeds fresh water. After cycle is over, the partially clogged return slowly always the backed up condensate to return to the boiler.
Ok here is something I've never quite understood. We are in a 14 unit, 5 story building. The common practice in cases like ours seems to be to have an outside temperature sensor and have the boiler come on when the outside temperature dropped below a certain point.
Thermal Efficiency Thermal efficiency is a measure of the effectiveness of the heat exchanger of the boiler. It measures the ability of the exchanger to transfer heat from the combustion process to the water or steam in the boiler.

Using Baseline Gas, the manifold pressure was adjusted to over fire the steam boiler by 25% above its rated input of 301,000 BTU/hr. When this condition was met, the gases were run in the following order: Baseline Gas was tested for 10 minutes.
The Enthalpy Drop Test is used frequently for monitoring steam turbines. This test involves a minimum number of instruments, but estab-lishes the efficiency of those turbine sections most susceptible to deterioration. An Enthalpy Drop Test can be conducted on any turbine sec-tion operating entirely in the superheat region,
The merits of efficiency are immense. That’s especially true when it comes to industrial boilers. An efficient boiler room can save a multitude of costs over its lifetime. Unfortunately, when many companies test their boiler’s energy efficiency, they find the numbers disturbing, to say the least. As Miura sales representative Brandon Hargett of Greensboro, North Carolina’s Boiler Master Inc. states, “the efficiency of your boilers are going to contribute directly onto what your cost
The term “boiler” is a carryover from the past when steam boilers were common, which boiled water to make steam. Today’s boilers are water heaters and typically use natural gas. Most can heat water in a range from 145-190 degrees, depending on the radiation system.
On April 13, 1909, the Power Test Committee was chartered by the Council of ASME to “revise the present testing codes of the Society relating to boilers, pumping engines, locomotives, steam engines, internal combustion engines etc.” In 1915, the “Rules for Conducting Performance Test of Power Plant Apparatus” was published.
