These are the undertakings of Energia Pecém and MPX Pecém II.
State-of-art thermoelectric power station that use the clean burning technology of coal.
Located about 15 km from Port of Pecém, in the State of Ceará,
the plants aim to supply the growing demand in the consumption of electrical energy of the Northeast region and the National Interconnected System.
The first plant (Energia Pecém), built in 50/50 partnership with EDP, will have two units, totalizing 720MW.
The second plant (MPX Pecém II), 100% MPX, will be capable of producing over 360MW.
The charcoal, raw-material used in the plant, arrives through the Port of Pecém,
from where it is unloads through special cranes and transferred to an enclosed conveyor.
This conveyor connects the port to the storage yard of charcoal.
It is enclosed, so that the coal is protected against the weather throughout the course,
by avoiding it to contaminate the environment, through the action of wind and rains.
In this yard, the coal is kept in stack in large rows for storage.
A series of special care prevent the coal to contaminate the groundwater of the region.
The floor is prepared, throughout the extension of the yard, in order to catch rain water and avoid it to infiltrate the soil.
And due to the watering process of coal piles, the particles are not carried through the wind.
In addition, in order to reduce the action of wind, a dense and high vegetation belt surrounds all over the yard.
The coal stored in the yard is carried through new conveyors that transport it until the bins.
There, the coal is pulverized and prepared for burning.
Besides the charcoal, another raw-material is necessary for the generation of power: water.
In this region, it is found in plenty amount due to the proximity to the sea.
In this process, ground ducts are used in order to catch water from the reservoir,
which passes through the treatment station, where it follows until the boiler.
In the boiler, the charcoal powder is burned and the heat generated warms the water, resulting in superheated steam.
This steam makes the turbine turns, by turning the thermal energy into mechanical energy.
The turbine makes the generator’ axis turns, then producing electricity.
After going through the turbine, the steam needs to be condensed in order to be pumped back to the boiler, where the process is repeated.
All this procedure takes place inside the condenser through steam cooling.
The sea water is used in order to cool the steam and, then, returned unchanged to the environment,
unless for a discrete rise in temperature.
As for the waste from the coal burning?
Due to gravity, the heavy ashes falls into the bottom of the boiler, where they are collected.
This material is reused for paving.
The light ashes are carried through the smoke coming out the boiler.
First, the smoke crosses the desulphurizer in order to eliminate the sulphur oxide.
Then the smoke passes a series of tapered filters,
over 99% of ashes are removed before released to the atmosphere by the chimney.
Finally, the generated electricity passes through the transformers so that the voltage is regulated to the standards of the transmission line.
Before reaching the consumer, the electricity still goes through a substation inside the plant.
This is how MPX works: by prevailing the environmental control using state-of-art technologies,
in order to provide Brazilian people with the energy required for the growth of the country with sustainability.
With our technology, the energy that moves the world can live in balance with the nature.
Energia Pecém and MPX Pecém II. More development, life quality and much more power for the State of Ceará.
