Modular and Transportable System
The Systems are “environmentally-friendly” and will comply with all current and currently proposed air permit requirements. They are computer controlled, fully automated and do not require any on-site operating or safely personnel (just low-cost labor to prepare the fuel). They have an extremely low “total cost of ownership”, have an uptime rate of >95% and are expected to have a useful life of at least 20 years.
System Benefits
The Systems enable commercial, industrial, agricultural, governmental and non-governmental organizations to affordably and responsibly use their waste to produce sustainable, secure and customer controlled heat energy, electric power and Co-Generation such as water purification and making ice. As shown in the above graphic, the Systems are prefabricated, modular, skid mounted and contain quick-connect fittings, making them easy to handle, ship and transport to the fuel source, whether at on-grid or remote off-grid locations such as workplace and mining camps and Indigenous communities. They can be placed on trailers (not included) or barges and transported to where they are needed, removed from the trailers, rapidly placed into service and utilized on-site for as long as necessary. If they need to be re-located, they can be easily and quickly dismantled, re-mounted on trailers and re-deployed to other sites. The Systems are not designed to be operated while on a trailer bed; they should be installed and operated inside of or under a suitable enclosure on an inexpensive cement or gravel lay-down pad. AgriPower’s modular, skid mounted and waste heat air conditioning, refrigeration and electric generation modules (shown below) can also be easily transported as shown. Rapid set-up and installation and dismantling and redeployment times are significant benefits of the System.
Benefits
- ABILITY TO USE LOW COST FUEL: The Systems can use a wide variety of readily available and inexpensive Biomass and many types of plastic waste as fuel.
- COMBINED HEAT AND POWER TECHNOLOGY: The unique design of the System enables the Heat Energy generated from its operation to be reused to provide virtually free heat, hot water and air conditioning to commercial buildings and greenhouses thereby increasing the number of System applications and their economic benefits. Customers (such as hospitals, universities, prisons, hotels and casinos) that require large amounts of hot water (for their kitchens, laundries, room showers and heated swimming pools) can also obtain an upsized combustion chamber to provide their facilities with additional heat and/or hot water and thereby reduce the significant amount of electricity and natural gas and fuel oil they purchase for these purposes.
- CO-GENERATION BENEFITS: The Heat Energy produced by the System is available as an additional and free energy source for Co-Generation applications to operate desalination and water purification equipment, ice machines and refrigeration units; and heat for commercial processes such as heat bonding and for drying paint and wood (or very wet fuel).
- SIGNIFICANT WASTE DISPOSAL AND FUEL COST SAVINGS:Using Biomass and plastic waste for fuel provides considerable savings from avoided waste disposal fees and taxes and also produces dramatic fuel cost savings compared to using diesel fuel oil. Fuel savings from the AG-375 System are expected to provide a financial payback period of about 3 years for an on-grid application and less than 3 years for an off-grid application (and even less time with the larger Systems). Fuel savings for an off-grid location using diesel fuel oil are estimated to be $10 to $15 million over a System’s expected useful life of 20+ years, compared to a comparably sized diesel generator set, depending on the future cost of diesel fuel oil.
- ENVIRONMENTALLY FRIENDLY; QUIET OPERATION:The System was engineered to be environmentally friendly and comply with applicable U.S. and EU permitting and zoning regulations when used with most types of Biomass as fuel. Even contaminated materials (e.g., certain construction and demolition materials such as plywood) may be used for fuel after adding a mini-scrubber that will capture the contaminants (e.g., paint and glue) during the combustion process. The System was designed to be extremely quiet; at a distance of 5’, its noise level is expected to be less than that of a telephone’s dial tone.
- EASE OF TRANSPORT; REDUCED FUEL TRANSPORT COSTS; RAPID ASSEMBLY AND INSTALLATION; SMALL FOOTPRINT: The Systems are prefabricated, modular, skid mounted and able to be shipped in or as standard 20’ or 40’ shipping containers, making them easily transportable to where the fuel is located, even in highly remote areas (thereby reducing or eliminating fuel transport costs). They contain quick connect fittings so they can be installed and commissioned with minimal on-site construction requirements. The installation, set-up and tear-down time will only be 3 to 5 days. When all of the modules are assembled, the AG-375 System will measure about 40’ long, 8’ wide and 12’ high and weigh about 80,000 pounds (40 tons). The fuel preparation and storage area, which will vary depending on each customer’s needs, could require an additional 20’ x 40’ area. The System should be installed and operated inside of a suitable enclosure on an inexpensive cement or gravel lay down pad.
- EASE OF USE; FULLY AUTOMATED OPERATION:The System has been designed to be easily and safely used in less developed countries by unskilled and inexpensive labor and be extremely user-friendly. It was engineered to be fully automated and operate continuously (i.e., 24/7) to produce base power and Heat Energy without the need for on-site operating personnel and can be remotely monitored by AgriPower or the customer via telephone, satellite or the Internet.
- PROVEN TECHNOLOGIES; RELIABILITY; LOW OPERATING COSTS: The Systems rely on proven “multi-zone, variable temperature” combustion and “high temperature” Waste Heat Generator technologies that have been in use for more than 40 years. The reliability of these proven technologies will translate into low operating and maintenance costs and very high uptime periods (95%+). Their uptime is expected to be at least 40,000 hours (5 years) between overhauls.
- HIGH ELECTRICAL AND HEAT OUTPUT; HIGH (60%+ to 80%+) EFFICIENCY: The Systems were designed to produce high electrical and Heat Energy output for their size and weight. They are expected to be extremely efficient and provide about 3 to 4 BTUs of electricity and Heat Energy for every 5 BTUs of fuel used, through the use of Combined Heat and Power technology and the customers’ use of low-grade heat for pre-heating water or heating buildings or greenhouses.
- TECHNICAL SUPERIORITY: Comparably sized Biomass-fueled units that utilize water, steam, gasification or high air pressure technologies are inferior to AgriPower’s unique Systems. Steam units usually require difficult and expensive to obtain ultra-pure water to operate and may require around the clock engineers to assure the safety of high-pressure vessels and to prevent corrosion. The AgriPower Systems are non-condensing and will not use any water, steam or high air pressure to operate (although an optional hot water heater may be added for heating and hot water and steam purposes). In gasification units, turbine blades become coated with the contaminants of combustion, resulting in expensive and continuing maintenance and downtime problems. By contrast, AgriPower’s fully sealed Waste Heat Generators do not come into contact with, or become damaged by, contaminants. Diesel generators require the purchase, transport and storage of highly polluting and increasingly expensive and unreliable to obtain diesel fuel oil.
- SYSTEM FLEXIBILITY:The combustors used by AgriPower have several significant advantages compared to other technologies in the market. For example, AgriPower’s combustor can efficiently operate within a stable range of temperatures from 1,000ºF to 2,200ºF. Many emissions problems arise because of chemical reactions that frequently occur in the 1,600ºF to 1,800ºF range. The AgriPower combustor’s ability to operate below the chemical reaction point enables it to operate cleanly using a wide variety of waste materials as fuel and without expensive emission control equipment being necessary.
Details:
Ease of Permitting. Unlike other combustion units, AgriPower’s Systems use a dual combustion chamber, clean technology design. During the combustion process, all of the combustion gasses and volatile chemicals on or in the waste (such as paint on wood or glue in plywood) are directed from the lower combustion chamber into the upper (extended) combustion chamber where the additional 1.5 to 2 seconds of extended dwell time enables the gasses to be completely combusted. This unique, two chamber design avoids the release of troublesome emissions into the atmosphere, enabling the Systems to comply with applicable air permit requirements. As a result, they can usually operate without the need for expensive emission control equipment and are frequently exempt from applicable air permitting requirements and their associated delays and costs.
Small Footprint; Attractive Payback Periods. The Systems’ compact design, with typical footprints of 50’ by 100’, enables them to be located where the waste is produced and where the heat energy and electric power are needed. This results in a highly efficient conversion of waste streams into usable heat and power and eliminates the cost of waste disposal and the carbon footprint from trucking the waste to a landfill. Our use of high efficiency, lower cost Generators means a lesser capital outlay and a typical net payback period of about 2½ to 4 years. A 60 ton per day AgriPower 1.2 MW (gross) CHP System can convert two tons (costing about $40.00 per ton) of inexpensive scrap wood (costing about $80) into 1 MW/hour (net) of electricity, compared to the 70 gallons (costing about $4.00 per gallon) of expensive diesel fuel (costing about $280) which contains the same usable energy required to produce an equivalent amount of electricity. This represents a saving in diesel fuel costs of about $1,680,000 per year (at 8,400 operating hours) without taking into account the reduced waste disposal costs, the value of free heat energy and the possible generation of carbon credits and Renewable Energy Certificates. As a result, at current prices, the CHP Systems are expected to save at least $50 million from avoided diesel purchases compared to a similarly sized diesel generator over their expected 30+ year useful lives.
Proven Software; Low Repair and Maintenance Costs; Superior Technology; World Class Manufacturers. The Systems, which are computer controlled and fully-automated, are run by customized and proven software and Programmable Logic Controllers. Their operations are constantly monitored and function with minimal operator input. Their remote monitoring capability enables our customers (and/or AgriPower) to continuously monitor and control their operation from distant locations. There is no need for expensive on-site technical or safety personnel, as they require only unskilled and inexpensive labor to prepare and load the fuel. The Systems are affordable to acquire, inexpensive and quiet to operate and come in a wide range of heat and power outputs that can be configured for each customer’s specific requirements. They are designed to operate continuously (i.e., 24/350) and safely, to achieve an uptime rate of greater than 95%, to require minimal and inexpensive maintenance, and to provide a low total cost of ownership. Their unique extended, dual combustion chambers, extended dwell time, use of over-, under- and mid-fire air distribution systems and screw augers for fuel handling ensure a consistent and an extremely thorough and “clean” combustion process with minimal (1% - 3%) residual ash. Their variable temperature technology (they can operate from 2,200°F down to 1,000°F) enables them to use problematic waste materials, such as plywood (with glue), painted and creosote-treated wood, high alkali palm waste and high silica rice waste, as fuel by operating below their respective chemical reaction levels. The integrated Steam Boiler, Generator, MSW Sorting Unit and the air conditioning and refrigeration units are produced for AgriPower by world-class manufacturers in the U.S., Europe and China.
Complete Turn-Key Solutions and Numerous Financing Options. AgriPower can provide a complete turn-key solution for each project and uses several well-known international, environmental services, engineering, procurement and construction companies (“EPCs”) to handle permitting, installation, start-up, maintenance and servicing of the Systems on a virtually worldwide basis. Multiple purchase, lease and other financing options are available including AgriPower’s no-risk, no-capital outlay, ”Shared Savings Program” for qualified customers. Under this Program, AgriPower provides its customers with substantial annual savings of waste disposal and diesel fuel costs without the customers having to use their own capital or assume any operating risks. AgriPower uses its own funds to install and operate the System at the Customer’s site and with its fuel and shares the savings obtained from the System’s operation, and from any carbon credits generated, with the customer.
