Due to the rapid development of economy, the scale of power plant construction continues to expand. Thermal power plants have obvious advantages in generating electricity. Although this method is low cost and low risk, it can continuously convert heat into electricity for use in the area. However, some thermal power plants in our country will have large energy consumption problems in the operation process, which will not only greatly waste coal resources, but also cause environmental pollution and bring losses to the operation of thermal power plants. This paper further analyzes the specific application of energy saving and consumption reduction in thermal power plants. Through the application of various measures, the overall operation efficiency of thermal power plants has been greatly improved.

In the construction and operation of thermal power plants, we should pay attention to the two goals of energy saving, environmental protection and energy saving. In the construction stage, the energy consumption problems existing in the construction and application of thermal power plants are analyzed, energy saving points are determined, and energy consumption is reduced by investing in new environmental protection and energy saving technologies. From the current situation, the new environmental protection and energy saving technologies applied in the construction of thermal power plants are mainly concentrated in five aspects: environmental protection, coal and water treatment, electrical energy saving, boiler energy saving and external wall insulation. It should be pointed out that the new technology of environmental protection and energy saving is comprehensive, and its comprehensive impact needs to be paid attention to. Based on the application of energy-saving technology in the construction of thermal power plant and environmental protection, this paper discusses the basic application of energy-saving technology in the construction of thermal power plant.

Under the influence of various industrial research results and practical experience, China's industrial manufacturing level has been greatly improved. However, the environmental situation is affected by various environmental problems that arise during the development and accumulation stages. In order to promote the sustainable development of China's economy and promote the sustainable development of various industries, we need to pay more attention to environmental protection and energy conservation. In the field of power generation, thermal power generation and other traditional methods will bring serious environmental pollution. Therefore, in recent years, the industry has paid more and more attention to the realization of environmental protection and energy conservation goals and related technology research. In the construction stage of thermal power plant, it is necessary to clarify the objectives of construction and use, and pay attention to the energy consumption and environmental impact during construction. Through reasonable technology selection and upgrading, the comprehensive construction of thermal power plants will be more in line with the current requirements of environmental protection and energy saving, and will also promote industrial upgrading and professional development.

Thermal power plant has its particularity. Thermal power plants should not only provide power resources, but also meet the demand for heating. Therefore, compared with ordinary power plants, the daily operation of thermal power plants will be restricted by more factors. For example, the unit size of a thermal power plant is smaller than that of a thermal power plant, and its boiler capacity is larger than that of a thermal power plant. In addition, thermal power plants need to complete different types of water treatment and carry out a large amount of water treatment. In the process of building a thermal power plant, the construction location should also be considered. Under normal circumstances, it is necessary to build around the heating demand area to avoid large heat loss due to excessive heating distance. In the construction of thermal power plants, it is necessary to pay attention to reasonable site selection, combined with thermal power supply demand, development demand and other factors, do a good job of internal construction planning, and leave a certain flexible development space.
