Process heating and drying describes heating that is needed as a direct part of an industrial production process - for example, drying, curing, melting, reacting etc. This kind of heating often needs to be continuous, so boilers are frequently used to provide the heat source - dryers and evaporators use the heat in the process.
The process heating technology overview (PDF) gives an introduction to the main process heating energy saving opportunities for businesses.
It's staggering to think that about 40% of the energy used in UK industry goes on process heating and drying. Cutting the energy costs of process heating is often a great way for a company to save money.
Happily, up to 10% of this energy could be saved using straightforward techniques.
Re–using heat from a process makes financial sense – you’ve already paid for it, so see if you can re-use it.

A well-maintained boiler is far cheaper to run. So, closely monitor your boiler’s combustion efficiency and schedule regular maintenance work.
