Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 13338-1991 "Basic Rules for Determination and Calculation of Thermal Balance of Industrial Fuel Furnace", and GB/T 13338-1991 Compared to the main technical changes are as follows:

--- Chapter 2 "normative reference documents", updated the number, name and nature of the reference standard;

--- Chapter 2 "normative reference documents", added GB/T 218, deleted the abolished standard GB 2586, GB 2588;

--- Chapter 3 "Terms and Definitions", the new term "

1 Scope

GB/T 13338-2018 is the Chinese national standard on basic rules for the measurement and calculation of thermal equilibrium of fuel-fired furnace in industry, in the field of manufacturing 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 7 June 2018 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 January 2019. Classification: ICS 25.180.10, CCS K61. 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.

This standard specifies the terms and definitions of thermal equilibrium measurement and calculation for industrial furnaces using fuel, thermal balance and heat budget, and thermal balance measurement. Requirements, calculation methods, and measurement reports. This standard applies to industrial furnaces using solid, liquid and gaseous fuels, such as rolling steel heating furnaces, soaking furnaces, heat treatment furnaces, cupolas, stepping Furnace, hood furnace, conveyor belt furnace, etc., as well as tunnel kiln, downdraft kiln and other industrial furnaces (hereinafter referred to as "industrial furnaces") for various purposes Balance measurement and calculation.

Note. The measurement items listed in this standard do not have to be carried out for all kinds of industrial furnaces. This standard does not include all the thermal balance tests of various industrial furnaces. Set the project. The measurement items of various industrial furnaces are specified in the respective heat balance standards, and the items not included in this standard are supplementally listed.
