Comparison of CO2 GenerationCxHy + (x+y/2) O2 → x CO2 + y/2 H2O
In Japan (Using the emission factor of Japan):
CO2 Generation by city gas combustion:
0.050 t-CO2/GJ / 40% = 0.12 t-CO2/GJ
CO2 Generation by fuel oil C combustion:
0.072 t-CO2/GJ / 40% = 0.18 t-CO2/GJ
CO2 generation by power generation: 0.000518 t-CO2/kWh
0.144 t-CO2/GJ / 85% = 0.17 t-CO2/GJ

Ecolead furnace achieve 5% energy saving compared with the
conventional end-port.
Electric booster realize the pull up or improvement of the glass quality.
Well balanced design is important, considering with energy cost and CO2
emission case by case.
Insulation design with using THERMOTECT WALL® realize epoch-
making energy savings through low or no degradation of performance.
