Moisture, ash, and volatile matter contents, combustion heat and mech. strength of a peat were examd. and compared with the results obtained for eco-pea coal and wood pellets. Burning of peat in heating boilers resulted in emissions of CO, NOx and particulate matter (PM10 and PM2.5) in amts. close to the emission accompanying the combustion of wood pellet but much lower than for eco-pea coal. The use of peat was economically viable.
