Energy recovery

By incinerating the solid waste, the energy containing in the waste is released and transformed into electricity by cogeneration facilities.

The plant has 2 waste heat recovery boilers and 1 steam turbine generator in the plant. In the cogeneration process, the heat energy from waste incineration is absorbed by water in the boiler to produce high pressure steam. The steam is conducted into the turbine to rotate the blades on the turbine rotor. By the function of reduction gear set, the turbine rotor can drive the generator and output electricity.

After having driven turbine rotor, the exhausted steam from the turbine is guided to the air cooled condenser (ACC). The steam is condensed to water again there. In order to complete a full cycle, the water is again conducted to the boiler to absorb the heat energy from waste incineration. Thus, the heat energy is recovered, no water or steam is wasted, and the residual value of solid waste is fully employed.

Normally, the electricity output is roughly 300,000 kWh per day or 90,000,000 kWh per year. Shortly speaking, the plant is able to provide power for 64,000 consumers, or about 16,000 homes for household use. That is to say, when the plant is well operated, the plant incinerates solid to solve the waste management problem, and, meanwhile, a great deal of electricity is produced to benefit the human society.
