Particle emissions from a domestic pellets-fired boiler

Characterization and combustion of olive pomace and forest residue pellets

“…The results of Fernandes et al [17], for commercial pine pellets, show small emissions of NO x , not exceeding in any case 30 ppm (13% O 2 ).…”

“…Other authors, such as Fernandes et al [17] show, for a small domestic pellet boiler, with a power of 10 kW, an average emission of CO of about 1150 ppm (13% O 2 ) for commercial pine pellets, equivalent to about 1438 ppm (11% O 2 ). Pyrenean oak pellets show CO emissions slightly higher.…”

“…Also, the comparative study of the performance of these equipments in the frame of current technical specifications has been carried out [12,13]. Other authors have also studied the behavior of domestic boilers [14][15][16], and the emissions arising from combustion processes [17].…”

Integrated Electrostatic Precipitator for Small‐Scaled Biomass Boilers

“…The initial approach was to develop an electrostatic precipitator (ESP) for biomass boiler systems, which are fueled with wooden or alternative fuels and with a maximum nominal heat output of 150 kW th 9. Biomass residue and waste materials, such as straw‐based fuels from the landscape conservation or the agriculture industry, generally show higher (dust) emission rates than standard biomass fuels 10–15. This defines higher requirements concerning the technical robustness of the combustion system and the ESP.…”

Achievement of high CO2 concentration in the flue gas at slightly positive pressure during oxy-coal combustion in a 300kWth furnace

“…Zhuo et al [12] investigated the formation mechanisms of submicron particulate matter (PM 1 ) by observing progressive changes of collected samples at different combustion stages. Fernandes and Costa [13,14] have pointed out that there are three types of particulate matter (PM) structures for all boiler operating conditions examined, namely: ultra fine (6100 nm) particles, submicrometer and micrometer sized particles/agglomerates, and isolated spherical and irregularly shaped large particles [13]. In the early combustion process, the PM is dominated by carbon, with smaller amounts of O and Si, while in the final stages of the combustion process, the PM composition is dominated by inorganic material [14].…”
