In the glass industry, cullet and silica are heated into molten glass and subsequently put through various heating processes before resulting in an end product.

Natural gas is mainly used in processes such as melting, refining, fabricating, annealing, fiberising, baking and floating bath.

The end products include television tubes, bottles, tableware and sheet glass.

Melting
High levels of luminosity and flame temperature will result in an increased thermal efficiency. It also provides a higher rate of heat transfer to the raw material. In addition, heat recovery by using regenerators offers substantial energy savings.

Refining
A constant heating value is crucial for this process in order to maintain the required temperature and also to ensure the product quality.

Fabricating
High flame temperature is essential to heat the fabricating mould. Clean combustion products, such as Natural Gas, are necessary to ensure that the mould surface remains clean at all times.

Annealing
A high velocity burner is used to create a uniform temperature distribution within the furnace.

Fiberising
Jet flames ensure stability and high temperatures even in high turbulence air conditions.

Baking
A high velocity exhaust gas penetrates and provides a constant temperature throughout the thick layers of glass fibre.

Floating Bath
Easy controllability of natural gas combustion creates a steady temperature profile to produce high quality sheet glass.
