The float glass production line achieves energy conservation and environmental protection through the following comprehensive measures:

1、 Energy saving measures

Fuel optimization and substitution: Using high calorific value fuels (such as natural gas) instead of heavy oil, coal tar, or co firing petroleum coke powder can reduce fuel costs by more than 40% while improving combustion efficiency.

Advanced combustion technology:

Full oxygen combustion: reduces heat loss from flue gas, increases thermal efficiency by 20%, and reduces nitrogen oxide emissions by 80%.

Oxygen enriched combustion: increases flame temperature and heat transfer efficiency, reduces fuel consumption.

Optimization of kiln structure: adopting shallow pool, narrow neck, and wide feeding design throughout the kiln to reduce heat loss and enhance the heating effect of the mixed materials; Optimize the roof structure and insulation materials to reduce energy consumption.

Recycling of broken glass: Adding 15% -30% broken glass raw materials, reducing melting temperature, and increasing the proportion by 2% can reduce daily fuel consumption by 0.1-0.5 tons.

Waste heat recovery: Utilizing waste heat from exhaust gas to generate electricity (such as a 7MW power station) or supply winter heating, improving energy utilization efficiency.

2、 Environmental protection measures

End of pipe treatment: Install efficient desulfurization, denitrification, and dust removal facilities to ensure ultra-low emissions of sulfur dioxide, nitrogen oxides, and particulate matter in flue gas.

Clean energy transformation: promote "coal to gas" to reduce carbon emissions; A photovoltaic power station will be built on the roof of the factory building, generating nearly 4 million kWh of electricity annually.

Resource recycling: Recycling solid waste such as refractory materials and tin slag, treating oily wastewater and dust, and achieving waste resource utilization.

Green process: Adopting Low-E glass online coating technology to reduce subsequent building energy consumption; The all oxygen combustion process reduces the generation of nitrogen oxides from the source.

Enterprises can achieve both energy consumption reduction and emissions reduction by combining automation control with waste heat power generation. Select energy-saving equipment and electric vehicles, and strengthen green management throughout the entire chain.

In summary, the float glass industry is promoting energy conservation, consumption reduction, and pollution prevention and control through technological upgrades, structural optimization, and circular utilization, helping to achieve the "dual carbon" goal.
