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

2. Furnace Design Concept Insulation Design with THERMOTECT WALL®

17

In 2015, It got the grand prize for excellent energy solution in Japan.

• High thermal resistance (>1600C)• High thermal insulation properties• Low shrinkage • Human body-friendly (Non RCF)• Low aging degradation

High Thermal Insulating Ceramic Materials

Application for Glass Furnace

Port

Reg wall Hybrid structure of melter wallRCF: Refractory Ceramic Fiber.BSF: Bio soluble Fiver.

19

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.
