ASME EA-1 pdf download.Energy Assessment for Process Heating Systems.
ASME EA-1 covers process heating systems that are defined as a group (or a set or combination) of heating equipment used for heating materials in the production of goods in an industrial plant. These systems, commonly referred to using terms such as furnaces, melters, ovens, and heaters, use heat sources such as fuels, e1ecthcit steam, or other fluids to supply the required heat.
This Standard sets the requirements for conducting and reporting the results of a process heating energy assessment (hereafter referred to as an “assessment”) that considers the entire system, from energy inputs to the work performed as the result of these inputs. An assessment complying with this Standard need not address each individual system component or specific system within an industrial facility with equal weight; however, it shall be sufficiently comprehensive to identify the major energy efficiency opportunities for improving the overall energy performance of the system. This Standard is designed to be applied primarily at industrial facilities, but many of the concepts can be used in other facilities, such as those in the institutional and commercial sectors.
Assessments involve collecting and analyzing data on system design, operation, energy use, and performance and identifying energy performance improvements. An assessment may also include recommendations for improving resource utilization, reducing per unit production cost, reducing lifecycle costs, and improving environmental performance related to the assessed system(s). Assessment activities shall include, but are not limited to, engaging facility personnel and providing information about the assessment process;
Periodic reporting to facility managers in the form of debriefings should occur as agreed upon by the assessment team. Also, irregularities may occur during an assessment (e.g., the failure of a computerized records system). If and when such events occur, the assessment team shall determine a corrective course of action.
The on-site assessment activities will conclude with a wrap-up meeting designed to outline the assessment investigations and initial recommendations. This meeting is discussed in para. 5.7.
4.8.5 Key Personnel Interviews. Subject to modification during the course of the assessment, the dates and times for the assessment team to meet with key plant or facility managers and process operators shall be specified and agreed upon by all individuals who will be participating in each meeting event. It shall be recognized that all data initially identified as essential to the assessment shall be obtained in discussions with knowledgeable facility staff.
4.9 Goaltheck
Prior to conducting the assessment, the assessment team shall ensure that the plan of action meets the stated assessment goals. The assessment plan of action shall be reviewed for relevance, cost effectiveness, and capacity to produce the desired results,
5 CONDUCTING THE ASSESSMENT
The assessment team should rollow the assessment activities shown in Fig. 1.
5.1 Establishing Data Collection Priorities
Requirements for the development of a preliminary list of process heating systems are detailed in para. 4.7.1. The requirements for data collection methods are detailed in para. 4.8.1. These should be reviewed and updated before conducting the assessment.
5.2 Determining the Functional Requirement of Each System
For each process heating system studied, the assessment team shall determine the system’s functional requirements, such as production output, quality (insofar as it can be controlled by the heating process), energy consumption (per production unit, if applicable), and emissions. The assessment team should poll appropriate plant departments to develop a complete profile of expectations or use original design parameters as a guide. These might include parameters such as energy use per unit of product (energy intensity) and product yield.
