3 Terms and Definitions
GB/T 10067.31-2013 and GB/T 30839.1-2014 and as defined in the following terms and definitions apply to this document.
3.1
Unit power consumption specificelectricconsumption
IF no furnace under the conditions specified in the test method for determination of the charge from the starting temperature of the heating, melting, and (or) raised to its rated temperature
Of course, the total power the main circuit and electrical auxiliary equipment and test charges consumed by the weight ratio of units of kilowatt-hours per ton
(KW · h/t).
4 energy parameters
According to the provisions of GB/T 30839.1-2014 Chapter 6, IF no furnace energy consumption parameters for the selected unit power consumption.
5 energy range
Energy range IF no furnace unit power consumption involved should be GB/T 30839.1-2014 Chapter 7, comprising.
a) IF no furnace main circuit input power meter power consumption, including supporting rectifier transformers, converter means, and the main circuit power transmission line
Stove like power consumption, power consumption and furnace material including the furnace heat loss and energy efficient furnace charge and the like;
b) IF no furnace mechanical and electrical auxiliary equipment power consumption, including self-supporting for the furnace tilting, opening and closing the lid and other hydraulic and electrical transmission
Dynamic system, cooling system, and control and measurement systems, such as power consumption;
c) auxiliary heating energy, such as natural gas may be blown, oxygen and other input heat and converted into electricity consumption;
d) an outer charge preheating furnace power consumption, but use their own waste heat (eg exhaust fumes outside temperature) is not carried out by preheating the count;
e) other should be included in the power consumption.
