16、g and application of ASME EA-1, Energy Assessment for Process Heating Systems. This document provides background and supporting information to assist in applying the standard. The guidance document covers such topics as rationale for the technical requirements of the assessment standard; technical g

17、uidance, application notes, alternative approaches, tips, techniques, and rules-of-thumb; and example results from fulfilling the requirements of the assessment standard. This guidance document was developed to be used as an application guide on how to utilize ASME EA-1.ASME EA-1 provides a standard

18、ized framework for conducting an assessment of process heating systems. A process heating system is defined as a group (or a set, or combination) of heating equipment used for heating materials used in production of goods in an industrial plant. Assessments performed using the requirements set by AS

19、ME EA-1 involve collecting and analyzing system design, operation, energy use, and performance data and identifying energy perform-ance improvement opportunities for system optimization. These assessments may also include additional information, such as recommendations for improving resource utiliza

20、tion, reducing per unit production cost, reducing life cycle costs, and improving environmental performance of the assessed system(s). ASME EA-1 provides a common definition for what constitutes an assessment for both users and providers of assess-ment services. The objective is to provide clarity f

21、or these types of services that have been variously described as energy assessments, energy audits, energy surveys, and energy studies. In all cases, systems (energy-using logical groups of industrial equipment organized to perform a specific function) are analyzed through various techniques such as

22、 measurement, resulting in the identification, documentation, and prioritization of energy performance improvement opportunities. This guide is part of a portfolio of documents and other efforts designed to improve the energy efficiency of indus-trial facilities. Initially, assessment standards and

23、guidance documents are being developed for compressed air, process heating, pumping, and steam systems. Other related existing and planned efforts to improve the efficiency of industrial facilities include(a) ASME Assessment Standards, which set the requirements for conducting and reporting the resu

24、lts of a com-pressed air, process heating, pumping, and steam assessments(b) a certification program for each ASME assessment standard that recognizes certified practitioners as individu-als who have demonstrated, via a professional qualifying exam, that they have the necessary knowledge and skills

25、to apply the assessment standard properly(c) an energy management standard, A Management System for Energy, ANSI/MSE 2000:2008, which is a stand-ardized approach to managing energy supply, demand, reliability, purchase, storage, use, and disposal and is used to control and reduce an organizations en

26、ergy costs and energy-related environmental impactNOTE: ANSI/MSE 2000:2008 will eventually be superseded by ISO 50001, now under development.(d) an ANSI measurement and verification protocol that includes methodologies for verifying the results of energy efficiency projects(e) a program, Superior En

27、ergy Performance, that will offer an ANSI-accredited certification for energy efficiency through application of ANSI/MSE 2000:2008 and documentation of a specified improvement in energy performance using the ANSI measurement and verification protocolThe complementary documents described above, when

28、used together, will assist organizations seeking to establish and implement company-wide or site-wide energy plans.Publication of this Technical Report that has been registered with ANSI has been approved by ASME.

This guidance document provides backgroun

41、d and supporting information to assist in applying the standard. 1.2 LimitationsASME EA-1 does not provide guidance on how to perform a process heating energy assessment, but sets the requirements that need to be performed during the assessment. ASME EA-1 was written in a form suitable for a standar

42、d, with concise text and without examples or explanations. This document was developed to be used in conjunction with the standard in order to give basic guidance on how to fulfill the requirements of the stand-ard. This document is only a guide, does not set any new requirements, and ASME EA-1 can

43、used with or without this document.2 definitionS assessment: activities undertaken to identify energy performance improvements in a process heating sys-tem that consider all components and functions, from energy inputs to the work performed as the result of these inputs. Individual components or sub

44、systems might not be addressed with equal weight, but sys-tem assessments shall be sufficiently comprehensive to identify the major energy efficiency opportunities for improving overall system energy performance. System impact versus individual component characteristics should be discussed.batch fur

45、nace: furnace into which the entire workload is introduced periodically.continuous furnace: furnace into which the workload is introduced continuously or at short time intervals.energy intensity: the ratio of the energy used during a heating operation to the product unit or mass that absorbs the ene

46、rgy. Also called “specific energy.“ energy use baseline: amount of energy use measured during the operating conditions existing at the time of the assess-ment. It should be expressed in terms of energy per unit of production, energy per unit of mass or volume pro-duced or in terms of energy per unit

47、 of time. Examples of the base line units are Btu/lb (kWh/kg), Btu/hr (kW), or Btu/unit of product (widget) (kWh/unit of product). functional requirement: description of what the plant expects the manufacturing system to do using the heat-ing system. The parameters could be expressed in terms such a

48、s production output, quality (insofar as it can be controlled by the heating process), energy consumption (per production unit, if applicable), and emissions. furnace: term generically used in this Standard to describe process heating equipment such as furnaces, melters, ovens, and heaters.heat bala

49、nce: a procedure in which an imaginary control boundary is placed around a process heating system and all energies and mass flows crossing that boundary are determined and summed. maximum installed energy input rate: The maximum amount of energy that can be supplied, usually expressed in such terms as Btu/hr, kW, kCal/hr, and kJ/h. In most cases the maximum installed energy input rating can be obtained from the nameplate of the heating equipment, the operating manual, design drawings, or documents provided by the equipment supplier. In some cases this is known as
