Performance Test Codes - ASME

PTC 6, on Steam Turbines, is the international standard for steam turbine acceptance testing. It was created and recently revised by a consensus group of vendors, owners, and users. It provides a standard, consistent, method for determining existing, retrofitted and new steam turbine performance within the minimum practical uncertainty.

A Guide to Steam Trap Testing | TLV - A Steam

2019-12-6 · Because the flash steam temperature is the same as that of leaking live steam, it is not possible to differentiate between a steam leak and regular condensate discharge by the measured temperature. An erroneous condition report based on temperature can lead to the unnecessary replacement of a good condition steam trap.

Steam Pressure Reduction: Opportunities and Issues

2013-9-26 · Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boiler's net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.
