“…The size of infrared radiation energy of an object and its distribution by wavelength are closely related to its surface temperature. Therefore, by measuring the infrared energy radiated by the object itself, its surface temperature can be accurately measured, which is the objective basis for infrared radiation temperature measurement [7] . Therefore, this study also provides a real-time visual monitoring system for the temperature field of coal spontaneous combustion in the goaf.…”

“…Em contraste, a termografia ativa requer fontes externas de estimulação de calor (Kee et al, 2012;Rehman et al, 2016), pode até ser sub-dividida de acordo com a natureza da estimulação como: Pulsed, Lock-in, Pulsed-Phase, entre outros (Maldague, 2001). A aplicação das técnicas de termografia ativa estão relacionadas com a detecção de defeitos em metais, monitoramento de processos industriais, entre outros (Meola et al, 2002;Montanini, 2010;Yuanlin et al, 2015;Zhao et al, 2017). A termografia infravermelha tem dois tipos de medições e análises.…”

RESUMOEste artigo tem como objetivo apresentar as metodologias, vantagens e limitações do ensaio da termografia infravermelha para a inspeção de pontes de concreto armado. Foi realizada uma revisão sistemática de artigos e de material acadêmico relativo à área. Esta revisão foca-se principalmente na aplicação passiva e em estudos tanto de laboratório quanto de campo. Utilizou-se uma abordagem crítica da informação disponível quanto a seu alcance. A termografia infravermelha apresenta-se como uma alternativa real para a detecção de defeitos nestas estruturas, sendo mais eficaz quanto mais superficiais sejam estas anomalias. Dependendo do trabalho a ser realizado é necessário levar em conta algumas considerações para obter melhores resultados. E é eficaz em combinação com outros ensaios. Palavras chaves: termografia infravermelha; inspeção de pontes; patologias do concreto. _______________________________________________________________

“…In foreign countries, the earliest scientific research institution engaged in the research of infrared thermography nondestructive testing technology is Wayne State University in the United States, which has been at the forefront of this field. At present, the application of infrared detection technology in China is relatively mature, including aerospace, electrical, medical, and so on [1]. Although infrared detection technology has many advantages, it is late in the field of special equipment inspection.…”

This paper introduces the application of infrared thermal imaging detection technology in the field of special pressure equipment, and applies infrared imaging detection to burners, low-temperature vessels, and tower vessels in chemical plants. The conclusion is that infrared detection technology can accurately detect temperature-maintaining defects in burners and low-temperature vessels, and can intuitively reflect the defect location in a high-heat form. For high-temperature equipment, the infrared characteristic form of insulation defects is generally displayed in an irregular chain shape, because the insulation is made up of materials that are spliced together and easily form pores at the joints. For low-temperature equipment, the humid environment caused by cold running may cause corrosion to exposed metals and even affect the process’s effectiveness. Infrared detection technology can visually reflect the location and degree of cold running, reduce equipment usage risks, and provide size and position guidance for insulation repair.
