The PyroGen Power Generation System integrates a continuous feed
pyrolizer with a specially modified internal combustion engine and
generator set.
The patent pending PyroGen™ EfW System combines US Thermal
Technologies’ Pyrolytic Conversion technology and I Power Energy
System’s baseload power production equipment into a fully
integrated Renewable Energy Platform in a pre-engineered,
factory-built package. The PyroGen™ EfW Power System features a
state of the art pyrolizer producing output gas which fuels
specially modified and hardened engine / generator sets. The
exhaust heat from the engines is used to maintain the operating
temperature of the Pyrolizer. The Thermal Conversion phase of the
system is designed to operate as a continuous feed, oxygen
starved processing unit capable of handling various waste/sludge
materials. The mechanics and technology selected for the system
produce a robust, easy to operate unit capable of processing a
wide variety of materials. The equipment is coupled with a state
of the art controls and automation package that senses process
conditions making the unit fully automated and self-regulating to
the characteristics of the various feedstocks.
The Pyrolysis unit produces a flammable “Pyro-Gas” fuel by thermally decomposing the organic waste feedstock material in the absence of oxygen. Pyro-Oils are also produced which can be used to generate power or refined into transportation or other fuels. The “Pyro-Char” byproduct has many potential applications, including the production of activated carbon or carbon black. The process is carbon negative and sequesters CO2. When the system is fed high BTU waste feedstocks, the resulting Pyro-Gas can run multiple engine/generator sets to cogenerate power. The exhaust gases provide the heat necessary to maintain the operating temperate of the pyrolysis unit. Feedstocks tested to date with sufficient heat content (BTU’s) to fuel the system include: • Presorted MSW (Municipal Solid Waste) • Waste Plastics • Animal Manures • Auto Shredder Waste • Food Processing Industry Waste • Waste Industrial Material • Sewage Sludges • Tires • Algae Residue • Wood Waste • Yard and Garden Waste The system can be designed and integrated to work with other upstream biomass feed stocks. The typical PyroGen™ system consists of: • Mixed Feed Hopper and Feed Auger • Input and Output Air Locks • US Thermal Technologies Pyrolysis Unit • Gas Scrubbing Unit• Oil Separation Unit • Pyro-Char Collection Unit • I Power Internal Combustion Engines and Generator Sets • Automated Process Controls Detailed Process Description: Waste feedstock is fed into the pyrolizer at a controlled rate. Within the unit, the waste material isconstantly mixed in an oxygen starved environment. Depending on the specific feedstock, the interiortemperature is computer controlled to maximize the system’s energy output and efficiency. Gases andoils exit through the top of the unit as char is collected at the bottom. Detailed Process Description: Waste feedstock is fed into the pyrolizer at a controlled rate. Within the unit, the waste material is constantly mixed in an oxygen starved environment. Depending on the specific feedstock, the interior temperature is computer controlled to maximize the system’s energy output and efficiency. Gases and oils exit through the top of the unit as char is collected at the bottom. Venturi scrubbers cool the gas, clean it of particulates and condense the oil for separation and collection. The scrubbing process water is recycled in a closed-loop system. The scrubbed gases pass through a secondary condenser and are then directed to the engine / generator set. During start-up, the system may utilize natural gas, propane or stored Pyro-Gas. Once operational state is achieved, external heating source(s) are no longer required. When high BTU waste feedstocks are used, the pyrolysis and power production processes become self-sustaining. The Pyro-Char is discharged and stored for eventual sale. Water misting may be needed to control dust in bio-char discharge auger mechanism. PyroGen™ System Throughput Capacity and Power Output: A standard full scale PyroGen installation is designed to process waste feedstocks in volumes up to 4,000 pounds (two tons) per hour and will normally support three (3) to six (6) I Power Energy Systems 365kw engines/generator sets producing up to 2.2 Mw.
