1 Project Description
1.1 Background of the Project
To accelerate the development in Liaoning coastal economic belt, Liaoning Provincial Government has proposed the development strategy of “Five Points and One Line” to realize the “First Prosperity in Coastal Region”, regarding the industrial base along the coast of Yingkou city as its key development zone in its strategy of “Five Points and One Line”. In this case, new buildings will emerge in swarms shortly, which urgently needs a large-scale heat source; otherwise, the development zone will see a chaotic scenario that small boilers and high stacks are erected here and there. Besides, the rate of central heating for Yingkou existing buildings is 54.2%( boiler rooms of above 14MW), of which, the small thermal power plants and hot water boilers of below 29MW should be eliminated according to China new energy policy. Therefore, a large heat and power plant is urgently needed to build so as to solve the problem of central heating of Yingkou city.
In addition, the current coal-based energy consumption will continue to exist for quite a long time, and no radical changes will take place. The coal-fired energy accounts for2/3 of the total consumption of Yingkou city. Coal－ burning smoke is the primary source of atmosphericpollution, especially in winter. Thus, a large thermal power plant equipped with updated technique and complete environmental protection facilities, would play a positive role in improving city air quality and citizens’ living quality.
To satisfy the thermal power demand of Yingkou, two heating supply units of 2×350MW, each capable of supplying a basic heating load of 325MW are planned to build in the south of coastal industrial bases of Yingkou city. One unit will be used to satisfy the heating demand of some coastal bases and the piping network entrusted by the Administration Committee of Development Zone is being laid; another unit of 1×58MW+4×29MW equipped with hot water boilers would be built for heating supply to an area up to 9.6 million m2 north of the city proper. A loan application from the World Bank has been submitted for the fund of heat supply network responsible for heating supply to the north of Yingkou city proper. This environmental management plan is prepared for the heating networksystem.
