Industrial ovens and furnaces used for high temperature heating in variety of industries and applications, from aluminium smelting and oil refineries to manufacturing and food processing, are the energy hogs of your business. Now it’s time to tame this wild animal to save on fuel and to reduce emissions, and the prescription is simple: reduce, recycle and recover. Here are some examples how:
Reduce excess air. Make sure your burners are operating at their minimum excess air level. Lowering excess air levels lowers the furnaces energy requirements. Reducing excess air by 15 percent on a furnace running at 10,000˚C will reduce the energy usage by more than eight percent. That’s eight percent less emissions, and eight percent lower fuel costs.

Recycle the energy being lost to atmosphere by preheating your incoming load. Preheating a load by 2,000˚C on a heating furnace running at 10,000˚C will reduce the energy usage by more than 15 percent. That’s 15 percent less emissions, and 15 percent lower fuel costs.

Recover the energy by preheating the combustion air. Using the exhaust gasses to raise the combustion air temperature by 3,000˚C on a furnace running at 10,000˚C will reduce the energy usage by more than 20 percent. That’s 20 percent less emissions, and 20 percent lower fuel costs.

Not sure where to start? Contact us to carry out a survey of your furnace and to get recommendations for the fuel saving option that suits your application the best.

We can upgrade your current system or design and supply a new system to optimise the performance of your furnace. Among the equipment we supply there are burners, controls, safety systems, gas trains and combustion air blowers from the leading European and American manufacturers.
