2、rican Society of Mechanical Engineers Printed in the United States of America FOREWORD Performance Test Code Committee No. 4 on Stationary Steam-Generating Units was reorganized in May, 1958 to rewrite and bring up to date the 1946 edition of the Test Code for Stationary Steam-Generating Units. Duri
3、ng the formulation of the new Test Code, PTC 4.1-1964, the technical committee brought to the attention of the Performance Test Codes Committee that for the Air Heater, an auxiliary heat absorption equipment common to all large sttam generating units, there existed no power test code. PTC Com- mitte
4、e No, 4 recommended the development of such a Test Code as part of its assignment. The Performance Test Codes Committee instructed FTC Committee No. 4 to prepare such a Test Code as a Supplement to be known as PTC 4.3 on Air Heaters. This Test Code was developed and its format follows closely that o
5、f PTC 4.1, the Test Code for Steam Generating Units. This Test Code was approved by the Performance Test Codes Committee on June 9, 1966. Final publica- tion was delayed, however, until a number of suggestions made by the standing Committee were con- sidered and satisfactorily resolved. It was appro
6、ved and adopted by the Council as a standard practice of the Society by action of the Policy Board, Codes and Standards on November 8, 1967.

Thus: % LEAKAGE = % CO;! gas entering heater - % COZ gas leaving heater % CO2 gas leaving heater x 90 Experience has shown that the use of this factor, 90, will result in percentage leakage figures that are very close (plus or minus one percentage point) to leakage determined on a weight basis. 7
