Changsha Zhonglian Pump Co., Ltd. helps Guodian group to improve economic benefits by using waste heat

in order to ensure heating on schedule, Changsha Zhonglian Pump Co., Ltd. has also set up a special project headquarters. On the premise of ensuring the production process and ensuring the product quality due to the anchor and anchor chain, the product delivery is completed in a short period of one month, meeting the requirements of the construction period, And unit 1 passed the one-time acceptance

the condensation heat of the thermal power plant is discharged into the atmosphere through the cooling tower or air cooling island, forming a huge cold end loss, which is the main reason for the low efficiency of energy use in the thermal power plant. It not only causes the waste of energy and water, but also increases rapidly with the increase of oil price, seriously (heat) polluting the atmosphere. The evacuation of condensation heat in thermal power plants is a common problem in China and even the world

nowadays, in order to solve this problem, many thermal power plants make full use of the waste heat generated in the process of power generation through technological transformation. On the one hand, it can effectively increase the economic benefits of power plants, and at the same time, it can improve the efficiency of energy utilization, so that thermal power plants, such as large energy consumers, can truly become large energy producers

waste heat utilization makes up for the heating gap in winter

currently in China, The electricity produced by coal-fired power generation accounts for about 60% of the total electricity. In actual production, due to the influence of various factors, the thermal power plants around the city directly discharge a large amount of heat into the atmosphere through the cooling tower in the process of power generation, which not only obviously affects the humidity and heat of the environment, but also causes a huge waste of energy

on the other hand, it is common in large and medium-sized cities in China that the central heating source cannot meet the rapidly increasing demand for heating. Therefore, if the waste heat of circulating water in the power plant can be used for heating, it can not only reduce the environmental heat pollution caused by the heat dissipation of circulating water in the power plant, but also alleviate the tension of gas and power resources caused by heating

how to use the considerable heat contained in the circulating water of thermal power plants has become one of the main measures for thermal power plants to seek benefits and development. It is reported that a large state-owned power plant of Guodian group in Hebei Province has undergone technological transformation this year to utilize the waste heat of the circulating water system and turn waste into treasure to provide heat source for local heating in winter

saving energy benefits the country and the people

it is understood that the waste heat utilization technology transformation of a large state-owned power plant in Hebei Province can not only make full use of the heat in the condensation link, create direct economic benefits for the power plant, but also make up for the energy gap of local heating in winter, which is beneficial to the country and the people

in order to realize the utilization of waste heat, the power plant carried out public bidding. After comparing all the enterprises participating in the bidding, the core equipment - hot water circulating pump was finally provided by Changsha Zhonglian pump industry, which has many years of manufacturing experience and technical strength. It is understood that Changsha Zhonglian pump mainly provides GS type high-efficiency single-stage double suction split centrifugal pump. This split centrifugal pump is not only optimized and designed by using excellent hydraulic models at home and abroad and combined with years of application experience, but also adopts a pre negative pressure system. When the pump is started each time, it does not need to manually fill the water, which is convenient to use, time-saving and labor-saving

in order to ensure the heating on schedule, Changsha Zhonglian Pump Co., Ltd. also set up a special project headquarters. On the premise of ensuring the production process and product quality, the production was completed in just one month. When scientific research institutions studied and explored new material technologies and new product processes, the experimental machine became an indispensable important instrument to deliver, which met the requirements of the construction period, and unit 1 passed the one-time acceptance

Changsha Zoomlion pump project leader said that being able to participate in the implementation of this project is not only an recognition for Zoomlion pump, but also an important opportunity to improve its own technology

the promotion and application of comprehensive utilization technology of waste heat in thermal power plants can not only obtain good economic and environmental benefits, but also improve the capacity of thermal power plants. Therefore, the paper industry will continue to be a one-year power plant with challenges and opportunities, which is not only conducive to cost saving, competitiveness improvement and environmental protection obligations, but also in line with the national development ideas on changing the development mode, energy conservation and emission reduction
