BLANCO, Jesús M  and  PENA, Francisco. Obtaining the Real Value of Difficult-Evaluation Heat Losses, Applied to the Calculation of Boiler Efficiency. Inf. tecnol. [online]. 2006, vol.17, n.3, pp.123-128. ISSN 0718-0764.

A study to obtain the real value of difficult-evaluation heat losses applied to the calculation of boiler efficiency is presented. A conventional value of 1 % over the gross caloric value of the fuel was assigned to each fuel. The proposed method allows to accurately determining these losses and is suitable for any type of fuel. For the study, both natural gas and fuel-oils (number 2 and low sulphur content fuel respectively) were selected. The conventional value of 1% over the gross caloric value has been useful to compare boiler efficiency as demonstrated in this work.

Keywords : thermal efficiency; boilers; heat losses; fuel-oil; natural gas.
