Wave Air Pump - WAP

 

Schematic Elevation View

 

    All materials are suitable for marine use and have a life span of 25 years.  CV’s are replaced as needed.

 

 

 BRIEF DESCRIPTION – WAP

WAP - Construction

bullet

The pump is cylinder shaped, small diameter, closed top, open bottom, protruding above sea level, kept vertical by a pump float and anchored to the sea bed.

bullet

The pump has two large diameter flared conic sections; one attached to the bottom of the pump and the other attached to the pump two meters above the bottom and covers a slotted pump section located one meter above the bottom of the pump.

bullet

Suction and Discharge Check Valves regulate the flow of air into and out of the pump.

bullet

A Discharge Line is fixed to the pump outer casing and runs down to connect through an elbow and flexible couplings to the piping network that feeds compressed air to the air inlet of a turbine.

bullet

The WAP has no moving parts, is light weight and needs a sea level of 14 meters. 

bullet

The WAP has minimum construction cost, and practically no maintenance costs other than visual inspection.

bullet

Discharge pipes and cross dummy piping are in integral part of the system mooring.

 WAP - Pump - Operation

bullet

The pump converts the kinetic energy of a wave into compressed air, collects it and feeds it to the air inlet of a fueled turbo generator.

bullet

As a wave approaches the WAP, the large amount of water rushing and accelerating upward inside the flared conic sections is confronted with a reduced area thus transferring part of its Kinetic Energy to the air trapped in the upper section of the pump to deliver a small quantity of air at high pressure.

bullet

Suction and discharge Check Valves regulate the movement of air into and out of the pump.

bullet

The compressed air is collected by a piping network and fed to the air inlet or combustion chamber of a fuel turbo generator.

bullet

The energy in the compressed air would be manifested by less fuel consumption for the same power output, thus leading to increased efficiency of the turbo generator. 

bullet

The principles of feeding compressed air and fogging (adding water vapor) to turbine inlet air or combustion chamber are well known and established in the turbine industry.

 WAP - System Construction

bullet

A WAP field consists of multiples of 10-Pump sets to provide the required generator power output.

bullet

Installing ten sets of 10-Pumps each (total 100 pumps) occupies 13.5 by 30 meters space.  Air Compressed to 100 psi and generator output are shown below.

bullet

System costs depend upon location, power output and Client requirements.

bullet

The system output in KW-Hours per year is the sum product of generator output in KW and the respective wave height durations in hours per year.  This information would provide system yearly gross income.

bullet

The above data determines system viability and profitability.

bullet

Fuel Turbines consume a good part of their output to compress the turbine inlet air.

bullet

The WAP system resolves the dilemma of having generator output only when a renewable energy source is available.  No energy source, No power output.  The WAP system provides dependable energy irrespective of availability of waves or wind energy.

bullet

The turbo generator operates with normal fuel consumption when no waves or wind energy are available, and operates at reduced fuel consumption when these energies are available.

NOVELTIES and Benefits– WAP

bullet

Based on proven engineering principles.

bullet

Small weights and structures.

bullet

Simple construction, low capital and maintenance costs, efficient energy extraction.

bullet

Auto-adjust to varying wave heights and sea levels, and provide dependable power output.

bullet

Resist storms, and are safe to navigation.

bullet

Zero emission

bullet

Can Withstand storms

bullet

Does not disturb marine life or shoreline scenic view, and provide a Free Floating Break Water Structure.

bullet

Safe to navigation

bullet

Sea depth requirement a minimum of 8.50 meters.

bullet

The WAP can be used to clean contaminated sea water.  Injecting compressed air into the sea water would aerate sea water and add oxygen to it.
