1 Scope

This standard specifies the electrolytic aluminum production molten aluminum holding furnace heat balance determination and calculation of baseline condition, heat balance measurement conditions, measured Items and methods, heat balance calculations, thermal efficiency and main technical indicators and thermal balance determination analysis and recommendations for improvement. This standard applies to aluminum production in heavy oil, gas, natural gas for the energy supply of molten aluminum thermal balance determination and calculation of the holding furnace.

2 thermal balance determination and calculation of the reference

2.1 reference temperature using the ambient temperature. 2.2 reference pressure using 101325Pa. Calorific fuel by 2.3 application based low (bits) calorific value calculation; conversion Joule card and, using 1cal = 4.1868J. 2.4 molten aluminum holding furnace heat balance measurement and calculation system for the furnace to take the entire system [ie fuel (heavy oil, coal, natural gas) pipe into the furnace Flue gas leaving the furnace flue] to the furnace wall as the system boundary.

3 Device Status

Equipment Condition 3.1 states, characteristics and problems in the thermal balance determination report, put into operation or put into operation since the last overhaul date. 3.2 Overview of equipment and production to fill the average of the month in the first three months of testing, content, and reporting formats are shown in Table 1. Table 1 Make. Workshop. Unit number. Item Unit Value or content Furnace - Fuel mode - Into the amount of aluminum t/shift The amount of aluminum t/shift Furnace volume m3 Furnace size m Furnace temperature control ℃ Completion date - Last Overhaul date -

4 Determination of thermal equilibrium conditions

4.1 test equipment and process requirements Molten aluminum holding furnace heat balance determination, the device should be put into operation in mid or last overhaul was to keep the furnace was measured during the production process must be stable
