Smart Tips For Energy Saving With Steam Boilers -

Using careful monitoring techniques lets operators manage the careful balance between too much air, carrying heat away, and not enough air, leading to fuel waste. Make sure that the boiler is running at optimum efficiency. For example, it is better to have one boiler running at 60-70% output than to have 2 boilers running at 30% each.
