Embodiment Construction

[0080] The present invention will be further explained below in conjunction with accompanying drawing and specific embodiment:

[0081] like figure 1 , figure 2 As shown, a glass energy consumption measurement method, including:

[0082] Step S101: Constructing a calculation model of energy consumption per unit mass of glass melting.

[0083] Specifically, the step S101 includes:

[0084] Step S101.1: Construct the heat dissipation calculation model of the glass furnace body during empty firing;

[0085] Further, during the empty firing, the heat dissipation calculation model of the glass kiln body is:

[0086] Q out =Q gas-out –Q smoke-out ⑤

[0087] in,

[0088] Q gas-out =q×V gas-out ×t ⑥

[0089] Q smoke-out = ρ smoke ×V smoke-out ×t×(t smoke-out –T)×c smoke-out ⑦

[0090] From formulas ⑤, ⑥, ⑦:

[0091] Q out =q×V gas-out ×t–[ρ smoke ×V smoke-out ×t×(t smoke-out –T)×c smoke-out ] ⑧

[0092] where Q out When it is empty firing, the heat dissip...
