Do you know the different energy that Glass bottle factories use?

Glass bottle factories use coal, natural gas and electricity as energy sources in the production process, each with its own advantages, disadvantages and characteristics:

Coal:
Advantages: Coal prices are relatively low and reserves are abundant, suitable for large-scale production.
Disadvantages: Burning coal will produce a large amount of pollutants, such as sulfur dioxide and smoke, which has a great impact on the environment. In recent years, many regions have implemented the "coal to gas" policy to reduce pollution.

In northern China, some factories still use coal. Because of sulfur dioxide, the transparent color of glass bottles produced by coal heating is generally darker, and the overall color is gray, which affects the presentation of the contents after the glass bottles are filled. The price is a bit low.

Natural gas:
Advantages: Natural gas burns cleaner and emits fewer pollutants, which helps reduce environmental pollution. High combustion efficiency, can heat the glass melt more evenly.
Disadvantages: Natural gas prices are high, and supply may be affected by geographical and political factors.

At present, most glass bottle factories in China have switched from traditional coal to natural gas. This has also led to several large-scale price increases in domestic glass factories in recent years.

Electricity:
Advantages: Electricity is easy to use, precisely controlled, and suitable for high-precision production processes. The sources of electricity are diverse and can be obtained through renewable energy (such as wind and solar energy), reducing carbon emissions.
Disadvantages: The cost of electricity is high, especially in areas with high electricity prices.

The melting furnaces of glass factories with electric furnaces are generally small, and production may be unstable due to power restrictions by local governments, unexpected power outages, etc. The heating method of electric furnaces is completely different from that of natural gas and coal. Domestic-related practitioners are not particularly professional, so the quality of the products produced is uneven.

The advantage of electric furnaces is that the furnace is small, the cost of changing the color of the material is low, and customized material colors can be made, and the minimum order quantity requirement is not very high.
Each energy source has its applicable scenarios and limitations. Glass bottle factories usually choose the appropriate energy source based on specific production needs, costs and environmental protection requirements.
