In most cases, if only because of their high operating temperatures and their capacity to cause injury or death as a result of some failures, furnaces and boilers should be included in predictive maintenance (PdM) programs that monitor their condition while they operate. |

Temperature monitoring can detect overheating delivery system components, help solve irregularities in electrical power supplies, predict operational machinery failure, detect blockages in supply pipes, and identify product inconsistencies. |

On a commonality between many petrochemical production equipment failures, whether lubrication, valve failure, tank settling or electrical-related, is temperature. That makes handheld thermal imagers, which capture two-dimensional images of the apparent surface temperatures of objects, a useful tool for regular predictive petrochemical maintenance. |

While many people in the power generation industry are familiar with annual infrared thermography surveys as part of PdM, the coal plant in this case study uses a thermal imager year round. There are two differences in their approach. |

In energy audits of homes and other buildings, technicians use blower doors in conjunction with thermal imagers. The blowers create positive or negative pressures within interior envelopes, making leaks much more apparent in thermal images. |

One set of tools for monitoring equipment in substations is Fluke's handheld thermal imagers. Thermal imagers capture two-dimensional representations of the apparent surface temperatures of electrical components and other objects. |

Surface temperature can tell you a lot about a building's structural elements, plumbing installations, and HVAC and electrical systems. Problems that are otherwise invisible to the naked eye are suddenly clear as day when you look through an infrared lens. |

Normally, people in industry use level indicators to tell how much product is inside a tank. So why do so many of them also use thermal imagers (infrared cameras) to do the same thing? It's because of the horror stories. |

This document discusses the cost savings of thermal imaging (thermography) PdM, provides guidelines for successfully capturing and analyzing thermographic data and describes how to integrate thermography into a predictive maintenance program. |

Electrical contractors typically use thermal imagers for predictive maintenance and troubleshooting, and sometimes during installation. |
