Energy Efficiency Improvement of Glass Furnace
PS Entity: Ihara Furnace
Outline of GHG Mitigation Activity
The introduction of an automatic combustion control system in glass furnaces reduces massive fuel consumptions and thus reduces GHG emissions. The core technology adopted by the project is the computerised combustion system. A glass furnace consumes a lot of fuel because their internal temperature reaches more than 1500 degrees Celsius, and operates 24 hours a day without stopping. The control system monitors air pressure, fuel flow, furnace temperature, oxygen rate, etc., and determines the optimum volume of air intake by automatically adjusting fuel valves and air inlet dampers.
Draft JCM MethodologyGHG emission reductions are evaluated based on specific energy consumption. The simplest option provides a default value, only requiring energy consumption and production data under the project scenario.
Calculation for GHG emission reduction amountERy = (AEMRR,y - AEMPJ,y) * POy
|ERy||GHG emission reductions (tCO2/yr)|
|AEMRR,y||Specific GHG emissions of reference scenario (tCO2/t-glass) → Default value can be used|
|AEMPJ,y||Specific GHG emissions of Project Scenario (tCO2/t-glass)|
|POy||Annual glass production volume (t-glass/yr)|
Expected GHG Emission Reductions
3,600tCO2/yr← Annual glass production of Ralaco: 12.500t-glass
← Specific GHG emission reduction: 0.288tCO2/t-glass
