| Popis: | Objective of this paper is an analysis of briquetted waste combustion in the low power boilers. Research was conducted for the 100 kW pyrolysis heating boiler and 200 kW heating boiler with grate stoker. Briquettes were made by compacting milled and crushed materials into cylinders 50 mm in diameter, with a length of 100-200 mm, density of 800 kg/M3. It was established that process of combustion in low power boilers has low thermal efficiency, value of which fluctuated within 60…74% for wood combustion and 50…70% for RDF briquettes combustion. Burning process was stable and characteristics of the RDF combustion were similar to the wood combustion. Incineration of the fuel briquettes had better effectiveness than burning of solid wood. During RDF briquettes combustion high CO content (up to 0,2% or 2000 ppm) in flue gas was observed, which is an indication of insufficient burning time. It may be concluded that waste incineration in low-duty plants is viable, but to secure complete combustion and desired temperatures process of combustion and heat extraction should be separate in terms of design. |
