Abstract
The present work is devoted to experimental measurement of combustion gasses and calculation of the energy losses with leaving gasses during exhaust nozzle for furnace of boiler Didacta-Italia power plant. The energy losses are presented by (1) – the comprehensive energy losses as, a – the losses energy with outlet exhaust gasses to the atmosphere, b - the fuel chemical energy which are not burned. (2) The comprehensive exchange losses due to the losses of water pipe leakage and the losses in steam or hot water leaving the boiler. By use of ORSAT device the combustion gasses are analyzed to calculate the percentage of concentration and molars of volumes of these gasses and ) , the result of calculation for the energy losses leaving with the gasses was (179.147 kj/kg) .Theoretical heat amount produced by combustion of fuel (gas oil) and the heat amount released by combustion gasses of steam in the boiler are also calculated , the difference between theme represent the steam generation unit losses .The comprehensive energy losses in steam generation unit for one Kg of fuel was (25.466 kW). Also the mass flow rate of burning gasses is calculated which was (430 kg /h).
