WFPP process
AEB’s Waste Fired Power Plant (WFPP) is a world leader in producing energy and products from waste. No other facility can match our environmental credentials. Our innovative plant has set a new global standard for electrical efficiency and maximising products from waste.
Every day, 600 trucks and a number of freight trains deliver 4,400,000 kilos of waste to the plant. The waste is mixed to create a homogenous mass with stable combustion properties. It is then deposited on a slide and pushed into the furnaces.
Generation of energy
The walls of each furnace are covered with water-filled tubes. The heat of the fire brings this water to the boil. The steam that is generated is used to drive a turbine that is coupled to a generator. The generator converts this movement into electricity. Using a reheater, steam is extracted from the turbine halfway through the process, and heated for a second time. This raises the temperature and the pressure, making it possible to achieve 30% electrical efficiency!
Products from flue-gas
Cleaning the flue-gas from the incinerator allows us to win back valuable raw materials. The sulphur that is recovered is used to produce gypsum board for the building industry, and calcium chloride is used for defrosting roads in winter.
Recovery from bottom ash
Not all of the waste is incinerated. The bottom ash that remains consists of cinders, granulates, glass and metals. To maximise the amount of material we can collect from this, in cooperation with TU Delft, AEB has built a pilot plant for recovering precious metals. The leftover residue can then be used to produce granulate and artificial sand for use in the construction industry.
Even then, we are not satisfied. AEB is working hard to develop an installation that can convert the last traces of bottom ash into even higher quality materials, such as raw materials suitable for the manufacture of concrete and asphalt.
