Foreword

This standard replaces GB/T 17719-1999 "industrial boiler flue gas heat and flame heating furnace Resource Calculation method and utilization guidelines." This standard compared with GB/T 17719-1999 main changes are as follows:

--- According to the provisions of GB/T 1028 for terminology, classification revised and improved;

--- According to the requirements GB/T 10180, GB/T 17954 and so on formulas, symbols and informative annex data standards referenced in the Amendment;

--- Based on waste heat "cascade utilization, with high-quality" principle, the use of waste heat 250 °C ~ 400 °C for increased encouragement for Power Generation terms [see 5.1b)];

--- Supplementary principles furnace industrial boilers and waste heat utilization, proposed to provide tail heating surface and the waste heat recovery unit to Seek range (see 5.4,

--- Complements the waste heat recovery and utilization management requirements (see 6.6);

--- Unified calculation formula idiomatic expressions and marked [see formula (2), (3), (5), (6), using the mass fraction and volume fraction Representation];

--- Standard Appendix A, Appendix B and Appendix C has been revised and complements. The Standard Appendix A, Appendix B and Appendix C are informative appendices. This standard by the National Standardization Technical Committee for Energy Management and focal points.

1 Scope

GB/T 17719-2009 is the Chinese national standard on calculation method and utilization guides for waste heat resource's quantity of industrial boiler's and flame heating furnace's exhaust gas, in the field of energy and heat transfer engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 8 April 2009 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 December 2009. Classification: ICS 27.060, CCS F04. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

Back calculation method of waste heat and waste heat boilers and industrial resources flame furnace smoke This standard specifies, as well as waste heat resources Receive and utilize the principles of management requirements. This standard applies to GB/T 1921, boilers and GB GB/T 3166 provisions/T 3486 stipulated continuous flame heating furnace (with Planning hereinafter referred to as "furnace") of the waste heat utilization engineering, design, technological innovation and management.

3 Terms and Definitions

The following terms and definitions apply to this standard.

3.1 With respect to the ambient temperature is 20 °C, relative humidity of 70%, the average volume of flue gas heat capacity at constant pressure is 1.359kJ/(m3 · °C) conditions Flue gas carried by waste heat for macro control targets. NOTE. The standard "m3" refers to standard conditions (1.01325 × 105Pa, 0 °C) under the measured gas volume units.

3.2 By country, industry and the relevant provisions of this standard, the technical and economic analysis to determine the available waste heat of the flue gas for the practical application of indicators.
