Recently, health risk assessment and early warning systems for high-temperature events have become critical concerns. However, current high-temperature warning systems primarily focus on temperature alone, which fails to accurately reflect the actual heat exposure levels and associated health risks. Therefore, this paper proposes an improved AHP (analytic hierarchy process) combined with a multi-level gray evaluation method for assessing human health risks during high-temperature conditions. A comprehensive early warning system is developed, incorporating various indicators, including human status, building conditions, and weather forecasts, making it more holistic than traditional temperature-based warning systems. A case study shows that the highest evaluation score for young individuals is 3.41, while elderly males receive the highest score of 2.5. Furthermore, the highest evaluation score for males is 3.41, while for females the highest score of 3.1. The warning results indicate that for young individuals, no alert is issued; for the elderly, a red alert is triggered; and for middle-aged individuals, the system issues orange and yellow alerts based on varying levels of risk. This study can be used to monitor health risk and provide alert message to humans. Based on the proposed early warning system, people can be able to predict health risk in time.

The steam trap plays the role in steam blocking and drainage.The appropriate trap can make the steam heating equipment to achieve the highest efficiency. To achieve the best results, it is necessary to have a comprehensive understanding of the performance and characteristics of various types of traps. This paper mainly introduces the types, principles, application occasions and characteristics of drain valves, and analyzes the types of drain valves that should be selected in the process of oil tank heating and the problems that should be paid attention to in use

This paper introduces the heating measures in the process of crude oil exploitation and transportation, meanwhile, it puts forward several process modes of solar heating technology, and illustrates the system principle and operation process of solar heating transportation of crude oil through actual cases, which opens up a new idea for the application of new energy technology in the petroleum industry and is conducive to the further promotion and application of new energy technology.
