publisher Copyright ® 1977 by THE AMERICAN SOCIETY OF MECHANICAL ENGINEERS All Rights Reserved Printed In U.S.A FOREWORD The purpose of the Bl33 standards is to provide guidance and criteria to facilitate preparation of gas turbine procurement specifications These standards will also facilitate response to such specifications The Bl33 standards provide essential information for the procurement of gas turbine power plants They apply to open cycle, closed cycle, and semi-closed cycle gas turbines with conventional combustion systems for industrial, marine, and electric power applications Auxiliaries needed for proper operation are covered Not included are gas turbines applied to earth moving machines, agricultural and industrial-type tractors, automobiles, trucks, buses and aeropropulsion units For gas turbines using uncon\'entlonal or special heat sources (such as: chemical processes, nuclear reactors, or furnaces or supercharged boilers), these standards may be used as a basis for procurement, but appropriate modifications may be necessary The intent of the B133 standards is to cover the normal requirements of the majority of applications, recognizing that economic trade-offs and reliability implications may differ in some applications The user may desire to add, delete or modify the requirements in this standard to meet his specific needs, in the preparation of his own procurement specification The B133.2 standard presents and describes features that are desirable for the user to specify in order to select a gas turbine that will yield satisfactory performance, availability and reliability The Bl33.2 standard is limited to a consideration of the basic gas turbine including the compressor combustion system and turbine Suggestions for improvement of this standard will be welcome They should be sent to The American Society of Mechanical Engineers, United Engineering Center, 345 East 47th Street, New York, NY 10017 American National Standard B133.2 was approved by the B133 Standards Committee and f'mal approval by the American National Standards Institute was granted on October 12; 1977 ill AMERICAN NATIONAL STANDARDS COMMITTEE

NATIONAL STANDARD BASIC GAS TURBINE exceed the value specified by the manufacturer for his particular machine and the defined duty cycle SCOPE This standard presents and describes features that are desirable for the user to specify in order to select a gas turbine that will yield satisfactory performance, availability and reliability The standard is limited to a consideration of the basic gas turbine including the compressor, combustion system and turbine COMPRESSOR SURGE 4.1 The compressor shall be designed to avoid de- structive surge during startup, as well as throughout the operating speed and load range for ambients specified by the user Any operating restrictions required to avoid surge conditions will be specified by the manufacturer GAS TURBINE- GENERAL 2.1 The design of the gas turbine, the selection of materials used, and the manufacturing techniques employed in its construction shall be of a quality required by the application to sustain mechanical integrity and deliver expected performance and availability throughout the design life of the unit, with appropriate consideration given to maintainability COMBUSTION 5.1 Design of combustors and transition sections shall consider fuels designated and ease of maintenance 5.2 Combustor shell arrangement shall ensure correct alignment of the fuel nozzle in the chamber Combustion system components shall be arranged for simplified service or replacement Nozzle parts in the gas path shall have provisions for adequate locking to prevent coming off during operation 5.3 Where dual fuel or other multiple nozzle arrangements are specified, inactive nozzles and their supply system should be designed so as to be available for immediate use 5.4 Means for assuring and monitoring proper operation of the combustion system should be specified by the manufacturer 5.5 The combustion system shall be of such design as to enable the gas turbine to comply with applicable emission standards and regulations ROTATING COMPONENTS (COMPRESSQR AND TURBINE) 3.1 Gas turbine rotors shall be mechanically designed to safely withstand transient speeds up to the turbine trip speed setting for brief periods at operating tern· perature 3.2 If field balancing is specified, the manufacturer shall state the method of performing this and the degree of disassembly required to balance 3.3 Adequate provisions shall be made to control thermal bowing of the rotor after shutdown so that restart can be made without excessive vibration 3.4 The design intent for all rotating (and stationary) blading shall be to prevent damaging fatigue stresses from being incurred as a result of aerodynamically induced excitation forces for the specified duty cycle 3.5 Where the manufacturer of the gas turbine also provides the driven equipment, he shall perform a lateral and torsional critical speed analysis of the combined driver-driven equipment system If the gas turbine manufacturer is to supply the driveronly,itis the responsibility ofthe user to see that such an analysis is performed 3.6 Vibration in the operating speed range shall not BEARINGS 6.1 Bearing housing cooling shall be provided as re- quired to minimize carbonization and deterioration of the lubricant 6.2 Bearings shall be designed to prevent instability at any operating speed The design shall be verified by an appropriate stability analysis 6.3 Means for monitoring condition of main shaft bearings should be specified AMERICAN NATIONAL STANDARD BASIC GAS TURBINE ANSI 8133.2-1977 6.4 Proximity probes if used, shall be mounted to face a journal surface or a scratch-free surface concentric with the journal surface 8.4 It is desirable that casings and duct work be designed to permit visual inspection of critical areas of the compressor and turbine blade path without major disassembly Access for visual inspection should be by means of small removable covers and/or holes designed for use of borescopes The intent is to provide maximum inspection for these areas with minimum disassembly 8.6 Jack screws, lifting lugs, eyebolts, or the equivalent shall be provided to facilitate alignment, disassembly, and reassembly When jackscrews are used as a means of parting contact faces, they shall be designed to prevent damage to the joint surface To facilitate disassembly and reassembly, bolting and doweling shall be designed and constructed for accessibility and to minimize seizure 8.6 The manufacturer should indicate maintainability features of his gas turbine, e.g., compressor and turbine casings split on the horizontal centerline, modular disassembly, etc 8.7 Insulation materials shall comply with OSHA regulations 8.8 All casing connections should be designed with appropriate consideration given to durability and maintainability SEALS 7.1 Where seals are required, their design should minimize heat input to the shaft so as to avoid conse.quential bowing of shaft if rubbing occurs 7.2 Seals shall be designed for ease of removal and replacement at overhaul 7.3 Utilized material shall be compatible with specified duty cycle and environment CASINGS 8.1 All pressure parts shall be suitable for operation at the most severe condition of coincident pressure and temperature expected 8.2 All casing joints shall be designed and constructed so as to maintain minimum leakage throughout the service life of the machine 8.3 Casings, supports and expansion joints shall be designed to prevent injurious distortion caused by temperature, load, or piping stresses Gas turbines shall have supports which will maintain proper alignment with connected equipment AMERICAN NATIONAL STANDARDS FOR GAS TURBINES TITLE OF STANDARD Gas Turbine Terminology (in preparation) • Basic Gas Turbine, 1977 • .• • • •.• •.•.•
