Gas turbines may be designed to burn either gaseous or liquid fuels， or both with or without changeover while under load. This standard covers both types of fuel.
ASME Gas Turbine .ontrol and Protection Systems B1...4 Published: 1978 (Reaffirmed Year: 1997)
The intent of this standard is to cover the normal requirements of the majority ofapplications， recognizing that economic trade-offs and reli-ability implications may differ in some applications. The user may desiretoadd， delete， or modify the requirements in this standard to meet hisspecific needs， and he has the option of doing so in his own bid specifica-tion. The gas turbine control systemshall includesequencing，control，protection， and operator information， which shall provide for orderly andsafe start-up of gasturbine， controlof proper loading， and an orderlyshutdown procedure. It shall include an emergency shutdown capability， which can be operated automatically by suitable failure detectors or which can be operated manually. coordination between gas turbine con-trol and driven equipment must be provided forstartup，operation， and shutdown.
ASME Gas Turbine Installation Sound Emissions B1...8 Published: 1977 (Reaffirmed Year: 1989)
This standard gives methods and procedures for specifying the sound emissions of gas turbineinstallations for industrial，pipeline， and utility applications. Included are practices for making field sound measurements and for reporting field data. This standard can be used by users and manu-facturersto write specifications for procurement， and to determine com-pliancewith specification after installation. Information isincluded， forguidance， to determine expected community reaction to noise.
ASME Measurement of Exhaust Emissions from Stationary Gas Turbine Engines B1...9 (Published: 1994)
This standard provides guidance in the measurement of exhaust emissions for the emissions performance testing (source testing) of stationary gasturbines. Source testing is required to meet federal， state， and local environ-mental regulations. The standard is not intended for use in continuous emissions monitoring although many of the online measurement methods defined may be used in both applications. This standard applies to engines that operate on natural gas and liquid distillate fuels. Much of this standardalso will apply to engines operated on special fuels such as alcohol， coal gas，residualoil， or process gas or liquid. However， these methods may require modification or be supplemented to account for the measurement of exhaust components resulting from the use of a special fuel.
ASME Procurement Standard for Gas Turbine Electrical Equipment B1...5 (Published: 1978) (Reaffirmed Year: 1997)
The aim of this standard is to provide guidelines and criteria for specifyingelectrical equipment， other than controls， which may be supplied with a gas turbine. Much of the electrical equipment will apply only to larger generatordrive installations， but where applicable this standard can be used for othergas turbine drives. Electrical equipment described here， in almost allcases， iscovered by standards， guidelines， or recommended practices documented elsewhere. This standard is intended to supplement those references and point out the specific areas of interest for a gas turbine application. For afew of the individual items， no other standard is referenced for the entiresubject， but where applicable a standard is referenced for a sub-item. A user is advised to employ this and other more detailed standards to improve hisspecification for a gas turbine installation. In addition， regulatory require-ments such as OSHA and local codes should be considered in completing the final specification. Gas turbine electrical equipment covered by thisstandard is divided into four major areas: Main Power System， AuxiliaryPowerSystem， Direct current System， Relaying. The main power system includes all electrical equipment from the generator neutral grounding connection up to the main power transformer or bus but not including a main transformer or bus. The auxiliary power system is the gas turbine section Ac supply and includes all equipment necessary to provide such station power as well as motors utilizing electrical power. The Dc system includes the battery and charger only. Relaying is confined to electric system protective relaying that is used for protection of the gas turbine station itself.
