1 PURPOSE

The purpose of this study is to present the technical and commercial proposal forsupply and installation of a power plant based on biomass combustion in the city ofMarbella.

The remains from the garden pruning of this town can be a perfectly usable energysource for electricity production by combustion of biomass and a thermodynamiccycle turbine - electric generator.

There is currently some 22,000 tons of raw biomass (high humidity), mainly palmpruning. After several treatments cleaning and drying are obtained 13,200 tons of

product clean and dry with a calorific value of about 8.82 MJ / kg (2,107 kcal / kg)able to be recovered directly from biomass furnace. All other products necessary forthe plant will come from nearby towns.

Proposes the introduction of a plant with the following characteristics:


4/25

That decree provides for two different rates for these plants: one for plants up to 2

MWe, and the second plant from this same power, the first being significantly higher.Thus, the most desirable approach for small plants which is a better economicperformance is to implement an installation of 2 MW of electrical power.

The needs of raw materials to feed a 2 MWe plant is to have a total of 32,000 net tonsof dry (with the PCI of 8.82 MJ / kg and commented). This amount implies annualneeds of a crude product of 53,000 tons (of which the city of Marbella has22,000).

In this regard, this study includes:

-Scheme of principle.

-Supplied appliances.

-Implementation of plant.

Preliminary-Economic Survey.

2 OVERVIEW OF PLANT BIOMASS

A biomass plant is the use of biomass combustion from a biomass boiler andelectricity production through organic Rankine cycle (ORC).

2.1 General Operation of plant

S f


6/25

Organic Rankine Cycle (ORC) power production is carried out with a Rankine cycle

operating with a fluid organic siloxane. This cycle consists of the following parts:

or Evaporation through a heat exchanger transfers heat the oil to the organic fluid,evaporndole.or Turbogenerator: steam is passed through a turbine coupled to an electric generatorproducing electricity.or Condenser through a heat exchanger condenses the organic fluid. His energy is

transferred to a closed water loop that evacuates the heat to the atmosphere througha refrigeration air or water.or pumping: the organic fluid is pumped in order to give the initial pressure required tore-enter the exchanger and start the cycle again.

Evacuation ofenergy: electricity passes first by a team of electrical conversion and

then transported through a power line to the point of connection to the outsidenetwork.

The use of the modules ORC cycles versus conventional water vapor is given by thegreater simplicity of operation of such modules and less maintenance, allowing theplant to be operated by highly skilled personnel without one. These factorssubstantially reduce operating and maintenance costs compared to a conventional


7/25

Minimal maintenance (3 to 5 hours per week).

Currently there are over 130 plants operating with these modules and over 30 underconstruction.

3 DESCRIPTION OF THE PROCESS AND supplied appliances

The plant is based on a biomass combustion line with a capacity of 10

MW input to the oven, heat oil boiler, capable of treating a wide range of particle sizesand moisture. The SCADA system control is manufactured such that the line can becontrolled from 25% to 100% of total capacity.

The following chart lists all the constituent parts of the plant and its interactions:

Hydraulic system is supplied to a silo extraction which may be either buried orelevated.

Silo length excl. cylinders: 12 m

Anc length cylinder area: 3 m

ho silo: 10 m hength

planned housingl silo: 4 m Volumen

total span of silo 500 m3

The burner fuel introducer device and combustion air to the furnace is controlled byenergy demand and the oxygen sensor by modulating control system, from 25% to100% capacity, with PLC and inverters that control both the flow flow of fuel andoxidizer, and depression in the oven, being a very robust system and experienced.


10/25

The staggered grid is equipped with movable grate sections to achieve a controlleddistribution of fuel. The speed of movement of the movable sections are adjusted to

achieve a drying of the fuel on top subsequently allowing a complete combustion withcauterization.

The primary air nozzles, secondary and tertiary are strategically located in the frontwall and side of the furnace, and on the grate level, to ensure complete combustion.


11/25

The generator has automatic tube cleaning air shot with installed valves on the topincluding the required air compressor with refrigeration dryer, filtration andmicrofiltration. The tube cleaning system greatly reduces the necessary cleaningcrucial thereby increasing the availability of such plants.

From the boiler, the gaseous fluid passes through a tower of economizing thatensures a high overall performance, then move to the multi-cyclone filter, where it is

The modulating control system means that all parameters are automatically adjusted

according to the load (demand) current of the boiler and the system is therefore always

5 IMPLEMENTATION

In the attached drawing is attached a proposal for implementation of the plant.Logically, the provision may vary depending on the location and site specific, butindicative level shows the elements of the plant and its distribution.

The space required for the collection of biomass is indicative and may vary greatlydepending on the availability of the same throughout the year and the safety orotherwise of a deputy minister continued.

To accommodate the equipment proposed a warehouse of 1200 m2, including anoffice area and control room, a room for the ORC module, the spacecraft for thecombustion equipment and an enclosure for the electrical conversion equipment.

Next to the ship lies the biomass silo of 150 m2 and the area near ORC moduleinstalls the equipment coolers.
