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 Methodology

GHG 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 amount

ERy = (AEMRR,y - AEMPJ,y) * POy
ERyGHG emission reductions (tCO2/yr)
AEMRR,ySpecific GHG emissions of reference scenario (tCO2/t-glass) → Default value can be used
AEMPJ,ySpecific GHG emissions of Project Scenario (tCO2/t-glass)
POyAnnual glass production volume (t-glass/yr)

Expected GHG Emission Reductions


← Annual glass production of Ralaco: 12.500t-glass
← Specific GHG emission reduction: 0.288tCO2/t-glass
