All ferrous, non ferrous and mineral smelting processes require the moltern material to be poured into ladles, tundishes and launders at some stage of the process. These items require to be pre-heated before use to prevent thermal shock from destroying them and to prevent to rapid cooling of the product.

As many of the processes also produce viable quantities of flammable gasses, most clients wish to use this gas as a heat source for their ladle heating stations. The Combustion Group have many years' experience in designing such equipment to take full advantage of the client's "free enegy". In many cases, this is augmented by other gaseous or liquid fuels to compensate for the intermitent loss of the primary fuel. These dual fuel burners and systems are custom-built to the client's particular needs.

In most cases, The Combustion Group designs and builds the whole system, including the refractory lined hood, with its raising and lowering system and the support structure.
