Alternative Energy for Power Generation

Alternative-Energy-Fuel

N-Viro Fuel™ Benefits

Availability of a cost effective, alternative energy resource in close proximity to power generating facilities.
Physical and chemical characteristics similar to that of coal, allowing the use of existing fuel handling and conveyance systems.
Ability to use organic waste streams such as sewage sludge, animal manure, pulp and paper waste as a fuel source.
Favorable BTU value.
Combustion temperatures similar to coal, thereby providing required stability.
Enhanced combustion stability of organic wastes.
Substitute for sorbent material including lime, anhydrous ammonia and other materials used to scrub sulfur dioxide and nitrous oxides from the combustion off-gases.
N-Viro Fuel™ contains between 20% and 45% water. The water can be used to decrease flame temperatures, and thus provide reduced NOx emissions.
Use of lime and limestone contained in the N-Viro Fuel™ can be used as a sorbent to scrub SOx.
Treated to Class A, EQ (as defined by US EPA) to provide a pathogen-free product that can be safely handled by plant personnel.

Competitive Advantage

The organic waste management industry has attempted to develop technologies to convert organic wastes into alternative fuels for power generation. Unfortunately, the industry to date has been unsuccessful due to the physical and chemical characteristics of the waste or waste derived fuel. Sludge and other organic waste can not be fed through conventional fuel handling equipment due to its high water content and particle size, among others.

Competing companies have developed thermal sludge drying systems that produce sludge-derived pellets with high organic content and low moisture content.  These companies have suggested that uses for the pellets include an alternative fuel. However, these pellets have not been demonstrated to feed in a manner that is compatible with the coal stream. This would include movement through conveyance and handling equipment without segregation, through pulverizers without powdering, and without explosive vapor release.

More importantly, these pellets have low combustion temperatures and unstable ignition profiles, which means the product has a high probability of igniting while in the material handling or storage phase prior to entering the boiler. Self-ignition and resultant fires are well documented. Therefore, power generators would not use existing coal handling and conveyance systems for these unstable products.

N-Viro differentiates itself from the competition with its ability to produce a product, N-Viro Fuel™, which has the physical and chemical characteristics similar to that of crushed coal. Therefore, N-Viro Fuel™ addresses the problems of handling, storage, and self-ignition.

Testing Complete

The overall testing measured the performance, operability of the material and ash content.

The test results confirmed that N-Viro Fuel™ in a 10% substitution performed well.

Performance Measurement: The overall efficiency of the boilers and the amount and type of emissions.

Process Procedure Measurement: The process point and introduction of N-Viro Fuel™  by the material handling system.
