Resumo: The present work presents the analysis of the horizontal flamotubular boiler, with furnace and aquatubular grid, B category, powered by solid fuel (wood logs). This boiler has a production capacity of 2500 kgV / hour, Maximum Allowable Working Pressure (PMTA) of 833.56 kPa and Hydrostatic Test Pressure (PTH) of 1,250.34 kPa and is installed in a dairy factory located in the city of São Geraldo – MG. This work its main objective is the study of thermal efficiency, taking into account the direct and indirect methods, proposals to improve this efficiency and a presentation of the operation and maintenance procedures for this equipment. During the work, technical data of this equipment, the fuel, and the environmental impacts caused by the burning of this fuel were noted and analyzed, and parameters that interfere with the thermal efficiency of the boiler were studied. A thermal efficiency of 74.65% was found, with a loss of 25.35%, referring to 11.18% of the dry combustion gases, 5.50% of the humid combustion gases, 4.30 of the fuel moisture, 4.00% by convection radiation, 0.25% by feed air humidity, 0.08% by incomplete combustion of fuel and 0.04% by unburned ash.

Essa caldeira possui capacidade de produção de 2500 kgV/hora, Pressão Máxima de Trabalho Admissível (PMTA) de 833,56 kPa e Pressão de teste Hidrostático (PTH) de 1.250,34 kPa e está instalada em uma fábrica de laticínios situada na cidade de São Geraldo – MG. Esse trabalho teve como objetivo principal estudo da eficiência térmica, levando em consideração os métodos diretos e indiretos, de propostas de melhoria dessa eficiência e uma apresentação dos procedimentos de operação e manutenção desse equipamento. No decorrer do trabalho foram investigados e analisados os dados técnicos desse equipamento, do combustível, além dos impactos ambientais causados pela queima desse combustível e de parâmetros que interferem na eficiência térmica da caldeira. Foi encontrado um rendimento térmico de 74,65%, com uma perda de 25,35%, referentes a 11,18% dos gases secos de combustão, 5,50% dos gases úmidos de combustão, 4,30 da umidade do combustível, 4,00% por radiação de convecção, 0,25% pela umidade do ar de alimentação, 0,08% pela queima incompleta do combustível e 0,04% pelas cinzas não queimadas.Universidade Federal de Viçosa - UFV2022-03-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1401510.18540/jcecvl8iss2pp14015-01eThe Journal of Engineering and Exact Sciences; Vol. 8 No. 2 (2022); 14015-01eThe Journal of Engineering and Exact Sciences; Vol. 8 Núm. 2 (2022); 14015-01eThe Journal of Engineering and Exact Sciences; v. 8 n. 2 (2022); 14015-01e2527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/14015/7228Copyright (c) 2022 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCruz, Marlons Lino daSiqueira, Antonio Marcos de Oliveira Campos, Júlio Cesar CostaSilva, Charles Luiz da2022-04-08T17:11:09Zoai:ojs.periodicos.ufv.br:article/14015Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2022-04-08T17:11:09Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false
