摘要：In the paper, the patterns of NOx formation from fuel bound nitrogen have beeen analyzed when burning various types of biofuel containing nitrogen, and also chip-ped waste of furniture production. It has been established that fuel bound nitrogen conversion to NOx slightly de-pends on type of fuel and on whether the nitrogen contai-ned in the fuel is naturally bound or is an artificial additive. It has been concluded that when heating the fuel up to 500°C, up to 30% of substances containing nitrogen releases from the fuel together with volatile substances. It has been shown that, when applying thermal processing of fuel, a part of nitrogen may be removed from the fuel. NOx formation can be reduced by rinsing the wood panels with water. 20% coke additives to fuel containing nitrogen allows reducing NOx concentration by up to 44%. Burning of high nitrogen content fuel together with low nitrogen content fuel provides ambiguous effect on NOx formation – it depends upon properties of this fuel as well.
