ABSTRACT
Increasing number of small heating sources in households means an increasing number of solid fuel pollutants. Many European households turn from gas to less green - wood combustion. Their impact on overall air quality has increasing trend in Slovakia, although other industries are decreasing the emissions of air pollutants. Small heating sources have around 15% share in air pollution by Particular matters. There are Huge pollutants with much more significant impact on air quality. The greatest one is US Steel which produces more than 50% of all the pollutants in entire country. This fact can be hardly changed. Smaller heating sources can be exchanged much easier. The paper focuses on CO, NOx, and PM10 matters measured in number of tests. The measurements taken in National Laboratory show the importance of proper wood combustion in wood gasifying boilers in order to maximize its efficiency and decrease the air pollutants emission. There are hundred thousand boilers installed, mostly old ones with high emissions in Slovakia. The most complicated for boiler producers is to decrease the CO emissions to minimum in order to meet actual EN requirements. There are expensive technical solutions or the fuel must be changed to high quality biomass – wood pellets. Classical steel or cast iron hot-water boilers are not able to meet the emission criteria without modification of their construction. Wood gasifying boilers can meet the criteria for CO and PM especially in laboratory conditions.
