Abstract
The use of boilers at residential and industrial levels is very common in various ap-plications and processes, leading to significant fuel and LPG consumption. For this reason, energy efficiency analysis is important to reduce losses caused by heat dissipation and to implement maintenance and changes in the generation process. The methodology used in the present study describes the heat losses using a thermal camera, water level gauge, steam thermometer, and environmental combustion analyzer to determine the composition of combustion gases. Efficiency calculations were performed through data collection using both direct and indirect methods of energy efficiency. The results obtained through the calculations determined an efficiency of 67,8%, utilizing 7,45 kW out of the 11 kW entering the system. It is concluded that the greatest efficiency loss occurs due to heat transfer by radiation and unburned gases. These findings suggest the need to improve component insulation and tube maintenance to reduce the Bacharach index and minimize losses.
