Experimental Investigation of the Effect of the Feeding System and Flue Gas Outlet Position on the Performance of Pellet-Fuelled Boilers

Depending on the growing industry and population, energy needs are increasing day by day. This issue makes it necessary use of renewable sources as much possible. There is a interest in pellet fuel pellet-fired combustion systems, which one sources. In this work, performance analyzes pellet-fueled boilers with two different feeding systems (horizontal-fed top-fed) flue gas outlet positions were carried out results discussed. Emissions O2, CO2, CO NOx temperature measured at certain point chimney. Boiler thermal efficiencies calculated compared each other. Direct indirect methods used to calculate efficiency boilers. Results showed that temperatures about 110 °C top-fed boiler 138 horizontal-fed boiler. The was higher than boiler, emissions lower Generally, better emission characteristics
