JB/T 50172-1999 Energy consumption classification of resin abrasive hardening furnaces

JB/T 50172-1999 This standard is a revision of ZB J01 022-88 "Energy Consumption Classification of Resin Abrasive Hardening Furnaces". This standard specifies the energy consumption levels of intermittent resin abrasive hardening furnaces that use electricity or generator gas as energy. Resin hardening furnaces are divided into first, second and third grades according to the comparable unit consumption of their furnace bases. Furnace bases that do not meet the third-grade comparable unit consumption index are classified as out-of-grade. This standard was first issued on March 5, 1988.

2 The energy consumption of the furnace is limited to the use of air circulation and air circulation, and the energy consumption of the furnace is not affected by the environment. 3.1: The average unit consumption of the hardening furnace H during the calculation period is calculated by formula (1): Zwa.r.
In the formula:
The comparable unit consumption of resin abrasives during the calculation period is kg Standard energy consumption of each furnace during the statistical period, k standard fuel coefficient of each furnace during the statistical period, electricity: r-1; generator gas: \,=.45; y product coefficient of each furnace during the statistical period, see Table 2; G

3.2 Statistics of each furnace's total energy consumption according to the formula (2): W-+ shape
I: color - total energy consumption of each furnace, k standard coal: that is, the energy potential of each furnace, k standard coal: the annual energy consumption of the circulating fan of the furnace, k standard coal. 3.3 Grinding and its conversion energy calculation formula (3): S
Wu: inductive and hardening energy consumption, m or kw·h:, - the low calorific value of the furnace gas or the current calorific value of the electric plate. 3.4 The energy consumption of circulating fan is calculated according to formula (4): 6
Wherein: W is the energy consumption of circulating fan, m or kW·h; ()
3.5 The low calorific value of fully washed coal gas in the boiler is generally based on actual measurement. If there is a national standard, it is selected according to 5651.1kJ/m: 2n=3600 k/ (kW3)
