Abstract Gas gas reheater is an important device for waste heat recovery and flue gas purification in thermal power plant. In this paper, the fracture failure reason of pressing plate bolt of guide bearing end cover of flue gas reheater in thermal power plant is analyzed. The results of optical microscope analysis show that there is no obvious abnormality in the metallographic structure of the two guide bearing bolts. The mechanical analysis results show that the hardness value, tensile strength and yield strength meet the requirements of relevant standards. SEM analysis showed that the fracture began at the root of the thread. The research results can provide reference for the operation and maintenance of flue gas reheater in relevant enterprises.

Using water-source heat pump for recovering waste heat of thermal power plant circulating water, mining of low grade heat energy. It can improve the power efficiency of comprehensive energy, but also can reduce the evaporation cooling water, the heat and moisture discharge to the environment. It has the economic, social and environmental benefits are very remarkable. Through the analysis of 600MW thermal power unit circulating water waste heat and calculation of water source heat pump heating, the feasibility of the water source heat pump technology in the recovery of power plant circulating water waste heat can be obtained.

The concepts of developing efficient and reliable schemes for the use of waste heat of low-potential energy resources in heat transformers (HT) are considered. Examples of using HT in several non-ferrous metallurgy plants in Russia and Kazakhstan are given: the production of nickel, zinc and ferroalloys. In the case of nickel production, two schemes are proposed for consideration: for summer and winter modes. The main object of study is a nickel production scheme using a lithium bromide absorption chiller (AbCh). Recycled water is the main source of utilized low-grade waste heat for AbCh. The cold obtained in AbCh is necessary for the technological process. The basic parameters were calculated under various extreme conditions, the energy effect of the modernization of the circuit was estimated, and equipment was selected. Studies have shown the feasibility of introducing AbCh into circuits with a large amount of waste heat. Low-grade heat utilization of nickel production using heat pump unit (HPU) in winter allows to obtain heat energy for heating water from the heating network and raw water for feeding the boiler house of a thermal power plant.Another example of HT use is a heat pump unit (HPU) in the production of zinc and ferroalloys. HPU is designed to heat feed water before chemical water purification and at the same time “cool down” the circulating water, which is then used on a series of electrolysis, replacing purchased artesian water. In winter, the heat produced at HPU is used for heating, ventilation and hot water supply, which allows to dispense with the services of a third-party thermal power plant.
