In high - temperature burning process , the nitrogen N2 contained in the intake combustion air reacts with O O2 in such a way that nitrogen oxide is formed . This creates emissions of NOx ( NO + NO2 ) . These emission must obviously be as low as potential for our surroundings . In horticulture , the flue gases from that combustion cognitive operation are used to get CO2 into the nursery - so in doing so , you also require to keep the proportion of NOx as low-toned as possible .
Until now , a NOx capacity of 35 mg , emitted by burner , was around the lower terminus ad quem in Dutch horticulture , say Geert - Willem van Weert and Ed Roeleveld of Vitotherm . " Below 35 milligram , several challenges arose that could not be solve well , while prerequisite are get strict worldwide . In some US states , 5ppm ( 10 magnesium ) is the max , and also , in several parts of the world , lower than 30 mg is demanded as the norms become strict . And that is what we have develop a burner for . The power range runs from 0.6 to 10 Mega Watt . We take into accounting the certifications and regulations in each state .
First burner will be in operation by autumnThe new burner works according to a different burning principle , achieving much grim emission . A flue pipe gas pedal cleaner is not postulate . Tests of the prototype carried out by the enterpriser in a science laboratory frame-up were more than successful . The results were below the expected 10 magnesium . The final engineering phase for the new burner pedigree has entered , and so are now quick to bring it to market , Geert - Willem and Ed Roeleveld tell us about the new burner , which will be forebode NOxtreme ® . The first burner is on order and will be commissioned towards autumn . The requirements of this burner are < 18 mg @3 % O2 . ( 9ppm ) .

So the burner was initially developed for the strange market but may also be of interest in the Netherlands , given the nitrogen problem here . " When we started working on it , the nitrogen discussion was not so much in play here . But we expect something from it in the replenishment market place in the Netherlands as well . Suppose you have expansion plans as a company , and you supercede your burner with this new one , you also get lower nitrogen deposition . "
All in all , this new burner is a vast pace for Vitotherm , conclude Geert - Willem and Ed . " A boundary has been cross , which we did n’t know was potential a year ago . "
