“The emissions from our new burner are at an absolute minimal”


In high-temperature combustion processes, the nitrogen N2 contained within the consumption combustion air reacts with oxygen O2 in such a method that nitrogen oxide is shaped. This creates emissions of NOx (NO + NO2). These emissions should clearly be as little as doable for the environment. In horticulture, the flue gases from that combustion course of are used to get CO2 into the greenhouse – so in doing so, you additionally wish to hold the proportion of NOx as little as doable.

Till now, a NOx content material of 35mg, emitted by burners, was across the decrease restrict in Dutch horticulture, say Geert-Willem van Weert and Ed Roeleveld of Vitotherm. “Under 35mg, a number of challenges arose that might not be solved simply, whereas necessities are getting stricter worldwide. In some US states, 5ppm (10mg) is the max, and in addition, in a number of elements of the world, decrease than 30mg is demanded because the norms grow to be stricter. And that’s what we have now developed a burner for. The facility vary runs from 0.6 to 10 Mega Watt. We keep in mind the certifications and laws in every nation.

First burner will probably be in operation by autumn
The brand new burner works based on a special combustion precept, attaining a lot decrease emissions. A flue fuel cleaner shouldn’t be wanted. Assessments of the prototype carried out by the entrepreneurs in a laboratory setup had been greater than profitable. The outcomes had been beneath the anticipated 10 mg. The ultimate engineering part for the brand new burner line has entered, and so at the moment are able to deliver it to market, Geert-Willem and Ed Roeleveld inform us concerning the new burner, which will probably be known as NOxtreme®. The primary burner is on order and will probably be commissioned in direction of autumn. The necessities of this burner are <18mg @3% O2. (9ppm).

So the burner was initially developed for the overseas market however can also be of curiosity within the Netherlands, given the nitrogen downside right here. “Once we began engaged on it, the nitrogen dialogue was not a lot in play right here. However we anticipate one thing from it within the substitute market within the Netherlands as nicely. Suppose you’ve got enlargement plans as an organization, and also you substitute your burner with this new one, you additionally get decrease nitrogen deposition.”

All in all, this new burner is a big step for Vitotherm, conclude Geert-Willem and Ed. “A boundary has been crossed, which we did not know was doable a yr in the past.”
