ASME PTC 34-2007 pdf download.Waste Combustors With Energy Recovery Performance Test Codes.
This Code contains instructions for testing waste fuel combustion systems with energy recovery. These facili- ties are defined as combinations of apparatus for con- suming the organic content of waste by releasing its chemical energy. For the purpose of this Code, perform- ance will be a measurement of the available heat energy released during the process. The recovery of useful energy in the form of steam is considered to be the measure of performance in this Code. It is not the intent of these testing procedures to obtain data on specific components of the system or to establish design criteria for these components or the process. Testing of individ- ual components such as fans shall be conducted in accor- dance with their respective test codes. See PTC 11. It is intended that in using this Code a detailed exami- nation will be made of the Code of General Instructions, PTC 1 and all other codes herein referenced before start- ing preparations for the tests. Such study is for the pur- pose of assuring an orderly and thorough testing procedure since it provides the user with an overall understanding of the ASME Performance Test Code requirements and enables the tester to understand readily the interrelationship of the various codes. Care should be exercised to obtain and use the latest revision of the Codes. Subsection 5-20 of this Code is concerned with sym- bols and their description, relating specifically to testing of waste combustion systems. This Code has departed from the use of symbols previously used in earlier codes in an attempt to make the symbols compatible with present-day word processors, personal computer spread sheets, and computer code. Hence a symbol set was adopted that does not use superscripts, subscripts, hyphens, or Greek letters. The ASME Supplements on Instruments and Appara- tus PTC 19 series referenced herein should be studied thoroughly, because the value of the test results depends on the selection and application of the instruments, their calibration, and the accuracy of the readings. Other items of vital importance to the value of the test are the proper determination of the characteristics of the effluent gas and water streams. The appropriate procedures for test and analysis procedures as listed herein should be followed carefully. This Code is intended as a test guide for all waste combustor systems with energy recovery, but it could not possibly detail a test applicable to every variation in the design of waste combustion systems. In every case, a competent engineer must study the particular facility and develop test procedures that are in agreement with the intent, guiding principles and required accuracy of this Code. Examples of the system variations atthe time ofpreparation ofthis Code include rotary kilns, refractory and waterwall furnaces, rotary combustors, mechanical grates, semi-suspension and suspension burning, multiple chamber solid hearth units, and two-stage combustion systems. Such systems were considered as the Code was being prepared. Portions of this Code may be used for waste combus- tors without energy recovery in the area of unburned combustibles in residue. For systems fired either by waste, or by waste in combination with other fuels in which heat recovery is a major portion of the heat output, PTC 4 may be used along with appropriate sections of this Code. The user is cautioned to note the difference between capacity and efficiency as defined in PTC 4 and PTC 34. Advanced instrument systems such as those using electronic devices or mass flow techniques, may, by mutual agreement, be used as alternates to the specified Code instruments, provided that applications of such instruments have been demonstrated to be no less accu- rate than required by the Code.
