How is this PENV new plant design different?
Steam Turbines are used in about 90% of all power plants in the world to turn steam into mechanical energy. The steam is created in a boiler by Conduction, a process where metal is heated to heat water. (similar to a Tea kettle) This water is heated to produce steam via gas, coal, nuclear energy, etc. PENV has Designed and Patented an Induction Steam Generating Vessel to use Induction Fields to heat metal flow channels to produce steam at the needed temperature, pressure and volume. PENV has designed a Plant that is extremely efficient using three forms of heating for our water, Induction, conduction and our Patented Heat scavenging reverse condenser. This condenser was designed to capture the waste heat as it exits the turbine. The spent steam is returned to a liquid state and moved back through the water process. This means that we are capturing a portion of this heat instead of letting it cool for discharge. To put it simply, higher water input temperature means less fuel used during the steam cycle. PENV Engineers have calculated that our condenser fitted to an existing conventionally fueled plant would result in at least a 15 to 25 percent reduction in fuel cost and a corresponding reduction is harmful emissions.
What is Induction and how is this more efficient than a conventionally fueled plant?
Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field.
To put it simply, Induction is accomplished by running AC power at low voltage and high frequency. The rapidly alternating magnetic field generates electric currents inside the conductor (in our case the flow channels in PENV’s Induction Steam generator vessel). These are called eddy currents. The resistance of the conductor material to these eddy currents produces substantial heat. The control of power, frequency, and coil geometry of our induction system gives us the ability to control the heat range available for our flow channels and tailor them for the process of flashing water to steam within our desired temperature range ( around 500 to 600 degrees F).
The chart below illustrates the the efficiency of using Induction as our primary heating source. W / cm square shows the heating/power transfer of each type of heating. The measurement is used to show R watts or power/heat transfer to metals applied to a one square centimeter area of the metal you are trying to heat. In other words, “how much power/heat can we transfer to one centimeter of the material to be heated.
Induction Energy Fields at Work
Types of Heating Power Transfer: watts/sq cm
Convection <———————————————> 0.5
Radiation <———————————————–> 8
Thermal Conduction <——————————–> 20
Infrared Point Emitters <—————————-> 400
Direct flame <—————————————–> 1000
Induction <——————————————-> 10000
The only methods with higher rates than induction would be Carbon Dioxide (CO2) Lasers and Electron Jets, both of which have extremely narrow focus energy beams and are of no use when trying to heat large volumes of material. The first three items on the list Convection, Radiation and Thermal Conduction are the existing heat transfer methods used in all Steam Boilers. The massive difference between Induction’s ability to transfer heat compared to a typical Steam boiler arrangement is staggering to say the least. This difference is at the Heart of the PENV Designs and Equipment and makes it possible for us to produce steam at the needed temperature, volume and pressure to operate a Saturated Steam Turbine Generator for relatively low amounts of electrical voltage. We have finished designing a new construction 120 MW plant and are presently trying to complete financing for this plant. PENV and Inductotherm Engineering calculations have shown that the power requirements to operate this plant will fall between 4 MWe to 8 MWe. This power will be used for the Induction feed water re-heat and steam generation vessels and all other plant associated needs. This will leave the plant with a surplus of 80 MWe to 100 MWe of clean, renewable / regenerative, zero emissions power to sell to the grid.
What about water treatment?
All steam turbines can basically produce distilled water as a byproduct. The difference is that PENV has designed accommodations in our systems to cleanly capture and use this fresh water to meet the demands of our growing population and Industry. The recent water crisis was not front page news when we developed our co generation Power Plant/ Desalinization / Water Treatment plant, but PENV always considered this configuration as a necessity for underdeveloped areas that are short on power and clean water. The portability and low build cost of our plants could easily save lives in many parts of the world. PENV’s Plant is also ideal for treating recycled water as well as waste/brown water. PENV’s Plant attached to a waste water facility would be a major asset to any utility looking to treat waste water as opposed to dumping it. PENV has also discussed the possibility of using our Plants to treat polluted bodies of water or to even filter potentially harmful water runoff from before it actually enters a lake or river. We can treat around 2.6 million gallons of water per day on a typical 100MW unit. Larger units and multi unit installations will have a corresponding increase in water treatment capabilities.
One of the main factors to consider with water treatment and desalinization is water transportation and movement. This has always been as costly as the treatment itself. The main cost for all of these plants is the Power/Electricity required to function economically. By Installing one our our Plants you will eliminate that bill and have a surplus left over to sell. As a clean, renewable and zero emissions power generator almost all of the U.S. states have open power purchase agreements to buy that extra energy. Our cost estimates for production at present time are extremely low ( about 3 cents per Kwh ) making our plants not only renewable, but competitive and in most cases substantially lower than Nuclear, Coal, Gas, Solar and Wind.
What if i do not need water?
The original plant configuration is just as cost effective and by not treating water you would dramatically extend maintenance intervals. This configuration could be run as an open or closed loop. A closed loop system is ideal for areas where warm water discharge or brine discharge is an issue. This would effectively be a dry cooled plant when using a closed loop. A closed loop system can effectively be built anywhere, from the middle of a city, an industrial park or even in the harshest conditions on the planet such as the desert or tundra.
What is meant by low to no emissions and is there really no need to fuel these plants?
Our plants can be started directly from the grid or by a start up generator. This start up time would require nominal emissions when compared to the output of our plant. The cleanest installations would be multi unit plants that could keep one unit on line while the other is in an outage or receiving repairs or routine maintenance. This configuration would be a zero emissions installation after start up.
PENV’s Plants run strictly on an electrically generated induction field and no other fuel is needed after start up. Other than maintenance our plants can run 7 days a week, 24 hours a day, 320 days a year Our plants are ideal base load plants that require less maintenance and offline time than a conventionally fueled plant.
What about Emissions and Compliance?
Our Plant is basically a big water heater that uses induction technology to flash steam. The unit when running will produce no/zero emissions. This means there is literally nothing to regulate. PENV’s proposed Florida plant has been planned using an existing 10k sf warehouse. PENV’s only site requirements included nearness to grid and simple building codes for the weight of our equipment.
I have a coal /gas/nuclear plant that is closed or in the process of being closed, can PENV do a conversion and is it affordable?
PENV can convert almost all plants to a clean, renewable Power Provider. If you have a Saturated Steam Turbine that can be operated in the 500 to 600 Degree F range we can do the conversion using much of your existing plant infrastructure. These old plants are an asset to their communities and our country and with PENV’s no fuel requirements they will be able to keep the lights on in their communities regardless of whatever happens to the National Grid.
As for affordability, PENV’s New Construction Project in Florida has a total price tag of 13 million dollars using a used 120MW steam Turbine Generator. All plants have different challenges of course, but a single conversion on an existing plant would definitely be less. Contact us for a quote and estimate, we can assure you that you will not be disappointed!
PENV has been pretty busy and an update on our progress is a year over due. We have been extremely busy with presentations and bids to numerous state and Federal Agencies as well as the private sector. We purchased a decommissioned 10.5 Mega Watt Power plant for Conversion and are planning to start this summer. This will be a CHP plant providing heating steam to local off-takers.
