Smoke, flame, and heat detectors are included in the active fire protection system that must be present on board. The function of these detectors is to detect fires early. This research aims to optimize the maintenance of smoke, flame, and heat detectors on board ships. This research was conducted using a qualitative method with primary data sources obtained through notes from interviews, field observations, documentation, and secondary data obtained from various literacies. This research was conducted at MV Pan Mutiara. In this study, it can be concluded that the optimization of smoke, flame,

In this study, the concept of bench test was established to replace the real distance test conducted outdoors for determining the sensitivity of UV flame detectors. In addition, the experimental apparatus of the bench test was developed and its validity was confirmed. The fire source of bench experiments used a microburner (6 mm diameter) using liquefied petroleum gas, and the bench test was performed with a flame height of 5 cm. The flame detector used in the experiment was a UV flame detector, and the amount of light was measured up to 2.4 m at a distance of 0.2 m from the fire source. The a

A fast response chemiluminescent flame detection approach is presented along with field test results from a fiber optic based flame detector device. Chemiluminescence, the light given off by molecules formed in their excited states, has long been recognized as a diagnostics method for use in combustion. The recent advent of higher quality optical fibers with improved transmission properties in the UV, as well as UV optical detectors, has made the use of chemiluminescence for gas turbine diagnostics and monitoring practical.

This paper presents experimental research findings for those involved in the early phase of fire in office buildings. Class A model fires with a reaction area from 5 cm2 to 300 cm2 were chosen for investigation. To mock up a fire, the following combustible materials typical of offices were used: wood pieces, heat-insulated linoleum, paper and cardboard. The main characteristics of a model fire were recorded: temperature in the combustion zone, heat release, time of complete burnout and concentration of flue gas components. Typical trends and histograms of changes of these characteristics over

The development of the oil and gas complex is one of the priority areas of the Azerbaijan economy. Oil and gas are among the most competitive Azerbaijan goods and are in high and stable demand from global consumers. Therefore, increased attention is paid to product quality. One of the methods for quality control of petroleum products is gas chromatography. Today it is a widely used physical and chemical research method. The capabilities of a gas chromatography are mainly determined by the enormous separating power of the chromatographic columns and the characteristics of the detectors. If the

In this study, the validity of an indoor bench test to replace and overcome the limitations of the real-range test, an infrared flame detector sensitivity test, was analyzed. A micro burner (diameter 6 mm) was used to substitute for the infrared flame detector. In order to measure the amount of light by distance, the voltage at the output end of the IR sensor was acquired. In addition, normal heptane (n-heptane) was used as a fuel for the actual distance experiment, and the amount of light at each distance was measured using an IR sensor. A bench tester was developed to measure the light outpu

The possibility of using semiconductor nanocrystals in photodetectors for optical detection of open flame has been explored. The spectral range boundaries of response of flame detectors have been concretized. In accordance with this, colloidal lead sulfide nanocrystals absorbing in the range of 1–1.5 μm have been synthesized. Photoresistors with different ligand compositions have been made from these particles. For the obtained samples, the current–voltage characteristics were measured and the photosensitivity and specificdetectivity parameters were calculated. A theoretical estimate of the fl

The need for selective and inexpensive detectors in liquid chromatography is of considerable interest in the determination of sulfur compounds. Of the available-selective sulfur methodologies, flame photometric detector coupled to gas chromatography is the most widely used. It has proven to be a sensitive and selective method for detection of heat stable and volatile sulfur compounds. Fundamentally, this technique is not applicable to high boiling and/or thermolabile sulfur compounds. More recently, hyphenated flame photometric detector has been utilized, with limited success, to monitor sulfu

A proposed "laser enhanced flame ionization detector" is described which retains the desirable properties of conventional flame ionization detectors (FID's), e.g., wide linear dynamic range, a predictable response for hydrocarbon detection, low noise level, and small internal volume, while providing significantly reduced detection limits. This superior detection capability results from improved response characteristics and a thousand-fold increase in ionization rate.

Abstract Hydrogen-fuelled carbon-free energy is a growing prospect for the future of several industries, among them the aeronautical and energy generation sectors. However, the transition to hydrogen comes with several challenges: flame stabilization due to the unique combustion properties of hydrogen compared to conventional fuels and control of nitrogen oxides (NOx) production due to the higher combustion temperature. In addition, the high flammability of hydrogen poses an increased risk of flashback in premixed configurations commonly used to generate low-NOx flames. As a consequence, resea

This project developed and evaluated methods for distinguishing between natural gases from different sources. Identification of particular "batches" of gas can be of considerable importance. For example, means of distinguishing between gases can demonstrate whether a gas appearing at the surface over a storage area is migrating storage gas or is gas formed by bacterial action above the storage zone. As another example, identification methods can allow detection of migration from a storage zone to an adjacent production zone. Two general methods were evaluated/developed in this project; tracers
