Douwe Egberts is an international Dutch brand founded in 1753 with numerous beverage brands (coffee, tea and hot chocolate).

Our standard (8x) DUO-Block the required NOx emissions where so low that we used FGR to reach that level. The BIO-gas what is produced from a water purification plant, is mixed to the burner with 2 gas trains. The combustion is monitored by an O2/CO controller that will adjust the combustion real time for the optimum combustion setting or change in calorific value of the BIO-gas that is produced. The used O2/CO controller is capable of having the O2 below 1% for maximum efficiency from the combustion.
