ORC Cycle for high efficency energy production The Rankine Cycle is a thermodynamic cycle which converts heat into work. The heat is

supplied externally to a closed loop, which usually uses water as working fluid. The Rankine Cycle based on water provides approximately 85% of worldwide electricity production.

The Organic Rankine Cycle's principle is based on a turbo-generator working as a normal steam turbine to transform thermal energy into mechanical energy and finally into electric energy through an electric generator. Instead of the water steam, the ORC system vaporizes an organic fluid, characterized by a molecular mass higher than water, which leads to a slower rotation of the turbine and lower pressure and erosion of the metallic parts and blades.

Efficiency:The ORC cycle has a high overall energy efficiency: 98% of incoming thermal power in the thermal oil is transformed into electric energy (around 20%) and heat (78%), with extremely limited thermal leaks, only 2 % due to thermal isolation, radiance and losses in the generator; the electric efficiency obtained in non co-generative cases is much higher (around 24% and more).

Advantage of ORC Cycle

High turbine / thermodynamic cycle efficiency;

Turbine low mechanical stress;

Absence of moisture during the steam expansion, responsible for the erosion of the blades;

Simple start up procedures;

Automatic and continuous operation;

Simple maintenance procedure;

No operator attendance required;

Long life of the plant (> 20 years);

No need to demineralize water..

Types of Bio fuels

Forest and/or woodworking industry waste (sawdust, bark, chips and woody materials in

pieces of various sizes and varying moisture content)

Agricultural waste (olive tree and vine pruning, etc.)

Food processing industry waste (tomato peels, solid distillation residues, apple processing

residues, fruit juice processing residues, brewery distillation residues, seed oil production

waste, bran processing waste, etc.)

Dedicated tree and grass crops (short-medium rotation)

Cleaning urban landscaping and embankments

Case fo application of ORC units with WOODY BIOMASS

APPLICATION OF ORC UNITS IN THE PELLET PRODUCTION FIELD

The biomass fired combustion system of a typical pellet production plant is usually fed with raw material such as bark and low quality wood chips coming from sawmill and wood processing industry close to the pellet plant.

Wood pellets are manufactured from untreated wood wastes, mostly sawdust and shavings, without any addition of chemical gluing agent.

APPLICATION OF ORC UNITS IN SAWMILLS

additional income can be obtained from electricity generated by the ORC unit without significant changes to the typical sawmill

Part of the electricity generated is used for the own consumption of the plant and the remaining part is sold to the grid, according to the market conditions about electricity value and possible subsidies

Wood Shredder

High throughput, low maintenance costs and high availability high performance shredders indispensable components of a modern biomass cogeneration plant.A special protection system for the cutting mechanism tools is availableAny non-crushable foreign object finding its way into the cutting mechanism is segregated using the fully hydraulic lowerable cutter bars.

Wood chip storage

The amount of storage required depends upon:

Minimum fuel storage; how much storage the plant’s financiers, regulators, clients and/or insurers require as a minimum to ensure continuous operation

Known fuel delivery interruptions; the length of periods when fuel delivery can be anticipated to be interrupted, say for long weekends, or when supplier’s mills are shutdown

Reliability of fuel delivery; there must be enough fuel on hand to cover likely transportation delays

Contingency supplies, to cover periods when forests are inaccessible for fire season, the wet season or during spring break-up.

Fibre supply contractual requirements; the ability to continue to stockpile fuel when the power plant is shut down for annual maintenance.

Possible Wood chip dryer solutions

The wet product is fed continuously into the low temperature belt dryer. Two conveyor screws distribute at first the wet product constantly across the belt width and level it. The suitable bed depth is variably adjustable and can thus be optimally adapted to the respective requirements fast and easily.

After distribution, the product is conveyed into the drying zone by means of the belt feed. Within the dryer tunnel, the generated hot air flows through the product. The hot air is generated by means of a heat exchanger from the available heating medium. During the hot air flows through the product layer, the moisture is dried off convectively and passed on to the air flow, which cools down by the necessary withdrawal of heat.

While air can be measured out exactly along the total length and thus adapted optimally to the respective drying section. Several radial fans (multivent system) provide an exact air measuring along the total length of the belt dryer. Much more air is required in the feeding zone (wet zone) than in the discharge zone. An adaption to these requirements utilizes the drying air very effectively and increases the efficiency.

The drying zone is sealed off from the feed and discharge zone; consequently there are only very few leakages. Additionally, the whole drying and hot air zone is operated in slight low-pressure so that no emission of leakage air is possible.

Other drying solutions can be possible

A housing

A turbine

An electrical generator

A pump

A heat exchangers

Piping

The housing is a hermetically sealed unit.

ORC fluid condenser

The condenser pressure acts as the turbine backpressure and thus has a considerable influence on the efficiency of the entire plant.

High overall thermal performance from the smallest to the largest unit

Excellent removal of non-condensables (air) ensures high heat transfer rates

Extremely low oxygen content of the condensate in the hotwell due to good degassing characteristics

Uniform and low energetic distribution of the bypass steam via steam dump devices

High condenser tightness on both steam and water sides

Proven and well accepted design due to many references and detailed condenser performance tests

Good accessibility for inspections, maintenance-free except replacement of the sacrificial anodes on the cooling water side

Our condensers are manufactured to our specifications, under our supervision and with our assistance in the workshops of carefully selected subcontractors or partners.

Cooling system

Cooling Tower

A cooling tower is a specialized heat exchanger in which air and water are brought into direct contact with each other in order to reduce the water's temperature. As this occurs, a small volume of water is evaporated, reducing the temperature of the water being circulated through the tower.

Dry Cooling

Diminishing water resources and increased water pollution concerns have led to the explosive growth of Dry Cooling worldwide. The major benefits for Dry Cooling are the elimination of water usage from the condensing power cycle, flexibility in power plant site selection and decreased time required for plant permitting.

Emission control

Extraction and filter systemsStandard design with welded and profiled sheet steel construction and an efficiency ratio of 80% or above. The model series and drive system are determined by the operational conditions (e.g. amount of material, dust content, temperature range, volume flow, overall pressure increase).The specification of the specific sound power levels for each of the various fan sizes complies with DIN 45635.
