PTC 19.10 - Flue and Exhaust Gas Analyses-Part 10

Presented are descriptions of methods, apparatus, and calculations which are used in conjunction with Performance Test Codes to determine quantitatively, the gaseous constituents of exhausts resulting from stationary combustion sources. The gases covered by this PTC Supplement are oxygen, carbon dioxide, carbon monoxide, nitrogen, sulfur dioxide, sulfur trioxide, nitric oxide, nitrogen dioxide, hydrogen sulfide, and hydrocarbons. Stationary combustion sources include steam generators, gas turbines, internal combustion engines, incinerators, etc. Many methods are available for measuring the constituents in flue and exhaust gases. This PTC Supplement describes in detail the most commonly used instrumentation and analytical procedures used for flue and exhaust gas analyses. Included are instrumental methods as well as (normally, wet chemical) methods. The instrumental methods include instruments used for non continuous or continuous sampling using extractive samples and in-situ type instruments that require no sampling system.

A112.6.3 - Floor and Trench Drains

This Standard establishes design requirements for floor, area, adjustable floor, and trench drains that are used inside of, or outside and immediately adjacent to, building structures that are typically nonresidential. It includes definitions, nomenclature, outlet types and connections, grate-free area, top loading classifications, materials and finishes, and variations in product design.

A112.6.1M - Floor Affixed Supports for Off-the-Floor Plumbing Fixtures for Public Use

This Standard applies to floor-affixed supports for off the floor plumbing fixtures, including combination carriers and waste fittings for water closets, and carriers for urinals, lavatories, sinks, and water coolers. This Standard covers definitions, materials and finishes, general requirements, strength and deflection requirements, and details of the various types of supports included herein.

B30.8 - Floating Cranes and Floating Derricks

Applies to the construction, installation, operation, inspection, and maintenance of cranes and derricks mounted on barges and pontoons. Floating cranes are convertible for excavation service and other uses that are categorically not considered to be lifting service. The requirements of this volume are applicable only to machines when used in lifting work.

A112.18.6 - Flexible Water Connectors

B29.23M - Flexible Chain Couplings

A chain type flexible coupling is one member of a broad family of mechanical shaft connectors that transmit torque without slip and that will accommodate a moderate misalignment between axially oriented driving and driven machine members. This Standard covers couplings of the chain type where two hubs having chain sprocket teeth are engaged by means of a length of roller chain or silent chain.

B107.15 - Flat Tip Screwdrivers

This Standard covers straight handle-type screwdrivers of flat tip design intended for manual operation in driving or removing screws with slotted recesses. The screwdrivers are of the types normally used by cabinetmakers, carpenters, sheet metal workers, production workers, mechanics, etc. The intention is to specify performance rather than design detail. Inclusion of dimensional data in the Standard is not intended to imply that all of the products described herein are stock production sizes. Consumers are requested to consult with manufacturers concerning lists of stock production sizes. Using a screwdriver as a pry bar or striking it with a hammer are clearly misuses of the tool, and nothing in this Standard shall be interpreted as condoning any tool misuse. Futher information about proper use of screwdrivers is contained in the Guide to Hand Tools-Selection, Safety Tips, Proper Use and Care.

PTC 4 - Fired Steam Generators

The rules and instructions presented in this Code apply to fired steam generators. These include coal, oil, and gas fired steam generators as well as steam generators fired by other hydrocarbon fuels. The scope 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. Gas turbine heat recovery and other heat recovery steam generators designed to operate with supplemental firing should be tested in accordance with Performance Test Code (PTC) 4.4, Gas Turbine Heat Recovery Steam Generators. This Code does not apply to nuclear steam supply systems, which are specifically addressed in PTC 32.1, Nuclear Steam Supply Systems. This Code does not apply to the performance testing of chemical heat recovery steam generators, municipal waste fired steam generators, pressurized steam generators with gas side pressure greater than 5 atmospheres, or incinerators. Municipal waste fired steam generators can be tested in accordance with PTC 34, Waste Combustors with Energy Recovery. Testing of auxiliary equipment is not addressed in this Code, but shall be governed by the following Performance Test Codes which apply specifically to the equipment in question: PTC 4.2, Coal Pulverizers. PTC 4.3, Air Heaters. PTC 11, Fans. Steam purity and quality shall be tested in accordance with PTC 19.11, Water and Steam in the Power Cycle (Purity and Quality, Leak Detention and Measurement). Methods used by this Code for determining emission related parameters, e.g., sulfur retention and flue gas constituents, are not equivalent to methods required by EPA, New Stationary Source Performance Standards, 40CFR60 and are not intended to be used for evaluating compliance with those standards or any other environmental regulations. This Code does not prescribe procedures for testing to determine chemical and physical properties of fuels. Applicable procedures may be found in the PTC 3 series or other pertinent standards such as those published by ASTM. This 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 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. See Section 6. Many references provide useful supplemental information in planning for a performance test in accordance with this Code. Those used most frequently are listed in Section 3.3.
