ASME PTC 4 – Fired Steam Generators

Scope of ASME PTC 4

ASME PTC 4 Fired Steam Generators. This Code provides rules and instructions for conducting performance tests of fuel fired steam generators. These include coal, oil, and gas fired steam generators as well as steam generators fired by other hydrocarbon fuels. The scope of ASME PTC 4 also includes steam generators with integral fuel-sulfur capture utilizing chemical sorbents. Steam generators which are not fired by coal, oil, or gas may be tested using the concepts of this Code, but it should be noted that the uncertainty caused by variability of the fuel may be difficult to determine and is likely to be greater than the uncertainties in sampling and analysis of coal, oil, or gas. For example, gas turbine heat recovery and other heat recovery steam generators designed to operate with supplemental firing should be tested in accordance with ASME PTC 4.4. Testing of auxiliary equipment is not addressed in this Code, but are covered PTC 4.2, PTC 4.3 and ASME PTC 11.

asme ptc 4This ASME PTC 4 Code does not prescribe procedures for testing to determine chemical and physical properties of fuels. This ASME PTC 4 Code specifically addresses equipment used for the generation of steam; however, the basic principles presented are also applicable to other working fluids. Certain types and sizes of equipment used for the recovery of heat released by combustion are not addressed in any specific Performance Test Code. This Code can be used as a general guide in developing performance tests for such equipment; however, such specifically developed performance tests shall not be considered ASME Code tests.

This ASME PTC 4 Code provides general procedures for conducting combustible fuel fired steam generator performance tests; however, it cannot possibly provide detailed procedures applicable to every steam generator design variation. Design variations considered in developing this Code include subcritical and supercritical once-through steam generators and oil, gas, stoker, cyclone, pulverized, and fluidized bed firing. For each performance test, a competent engineer must study the actual steam generator and its relation to the remainder of the steam cycle, and develop test procedures which are consistent with this Code. A test report shall be prepared. Many references, which are listed in this Code, provide useful supplemental information in planning for a performance test in accordance with this Code.

ASME PTC 8.2 – Centrifugal Pumps

Scope of ASME PTC 8.2

ASME PTC 8.2 Centrifugal Pumps. This Code provides directions for conducting and reporting performance tests of centrifugal pumps, including those of the mixed flow and axial flow types, under the following characteristics: (a) Total head produced by the pump; (b) Pump capacity (rate of flow through the pump); (c) Power input to the pump; (d) Efficiency; and (e) Net positive suction head requirements of the pump. This ASME PTC 8.2 Code applies to the testing of pumps utilizing liquids or mixtures of miscible liquids which have Newtonian viscosity characteristics. In addition to the foregoing this Code provides nonmandatory appendices which provide guidance related to the application of this Code.

The ASME Test Code PTC 8.2 (Secs 2.21, 4.45-4.48) reccommends use of an “effective vapor pressure”, which is determined by a laboratory procedure on the liquid sample containing the gas. The real requirement is to preclude the generation of any gas or vapor in the system or pump. The vapor comes from the change of state from liquid to gas and happens very quickly depending on the temperature and pressure.

ASME Y14.100-2004 – Engineering Drawing Practices

Scope of ASME Y14.100-2004

ASME Y14.100-2004 Engineering Drawing Practices. This Standard establishes the essential requirements and reference documents applicable to the preparation and revision of manual or computer generated engineering drawings and associated lists unless tailored by a specialty Standard. It is essential that this Standard ASME Y14.100-2004 be used in close conjunction with ASME Y14.24, ASME Y14.34, ASME Y14.35M, and ASME Y14.41. Incorporated into Y14.100-2013 is Y14.42 on Digital Approval Systems.

ASME Y14.100-2004 paragraph 4.32.3 uses soft language to discourage the practice of converting inch to metric and vise verse (“should not be used”). This is known as soft conversion. This is not an outright prohibition against dual dimensioning by itself. However, the practice of soft conversion is integral to using dual dimensions. With this practice discouraged, dual dimensioning is also discouraged.
