Foreword

YS/T 124 "carbon products manufacturing Determination and calculation of heat balance of the furnace" is divided into five parts.

--- Part 1. rotary kiln;

--- Part 2. Tank calciner;

--- Part 3. Electrical calciner;

--- Part 4. roaster;

--- Part 5. Graphite resistance furnace.

This section YS/T 124 - Part 1.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.

This part is YS/T 124-1994 "carbon products manufacturing Determination and calculation of heat balance of the furnace" in the rotary kiln section amendments.

Compared with YS/T 124-1994, the main changes are as follows.

--- Standardized units of measurement, symbols, highlighting the standard of rigor;

--- Furnace surface temperature of more realistic test requirements.

The non-ferrous metal part by the National Standardization Technical Committee and centralized.

1 Scope

YS/T 124 This part provides carbon products manufacturing various types of rotary kiln heat balance determination and calculation of the reference measurement conditions, measured Given project and calculation methods.

This section applies to all types of rotary kiln heat balance measurement and calculation method of producing carbon products.

2 Thermal balance determination and calculation of the reference and measurement system

2.1 reference temperature using the ambient temperature.

2.2 reference pressure using 101325Pa.

2.3 calorific value of the fuel calorific value calculated by application based low (bits); conversion Joule card and using 1cal = 4.1868J.

2.4 rotary kiln heat balance measurement and calculation methodology, including body kiln, kiln hood, kiln hood and the settling chamber (or combustion chamber), not including the cold but machine.

3 Determination of requirements and time

3.1 Determination of thermal equilibrium in the cycle time, must be in a rotary kiln measured under normal operating conditions, the production conditions and meet the maximum Organization when measured capacity.

3.2 Determination of time specified continuous determination of 6h, the number of measurements for each item not less than three times, and then take the arithmetic mean.
