YB/T 4209 Technical Specification for Regenerative Combustion in the Iron and Steel Industry
YB/T 4773 Determination and calculation method of oxidation loss of steel billets
3 Terms and definitions
The terms and definitions defined in YB/T 4209 and YB/T 4773 apply to this document.
4 Thermal balance test and calculation benchmark
4.1 Reference temperature
The average ambient temperature is used, that is, the ambient temperature of the regenerative industrial furnace in the workshop 1m away from the furnace wall or 1m away from the ladle or ladle roaster.
Average ambient temperature.
4.2 Fuel calorific value
The received low calorific value of wet coal gas is adopted.
4.3 Thermal balance test range
According to the test requirements, the whole furnace (including heat storage recovery device) or (and) the furnace heat balance of the industrial furnace is tested and calculated.
The thermal balance test of the ladle baking system includes the baking machine, air pipeline, gas pipeline, exhaust pipe and the baked ladle.
4.4 Thermal balance test time
For industrial furnaces, continuous measurement is performed when the type and specification of the materials entering the furnace remain unchanged and the furnace operating conditions are stable.
The measurement should be completed within 8 hours, and the number of measurements should not be less than 2 times, each time for 1 hour. The measurement of temperature, pressure, flow rate and other parameters should be not less than 1 hour per hour.
4 times and then take the average.
