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 "3.2 Thermal Stability" "3.3 Effective Heat" and its definition;
--- Deleted "5.4.4 units";
---"5.5.2.1 Determination of fuel consumption", increase "gas flow meter and according to pressure";
--- "5.5.2.2 Sampling analysis of fuel and determination of calorific value", clarifying the calorific value of solid fuel, liquid fuel and gaseous fuel
Determination together and calculation method;
--- "5.5.3.2 Air temperature" increased "cold thermometer, hot air thermocouple";
--- "5.5.7.3 Material temperature" increased "radiation pyrometer";
--- "6.1.3 Physical heat brought into by combustion air", regarding "b) gas fuel air coefficient а, analysis and fuel by furnace flue gas
The composition is calculated as follows.", a simplified formula is added;
--- "6.4 Thermal efficiency", added "equipment thermal efficiency refers to the effective use of energy in order to achieve a specific purpose
The quantitative representation is equal to the percentage of effective energy and energy supplied.

Basic rules for the determination and calculation of thermal balance of industrial fuel furnaces
1 Scope
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.
