Benefits of technology
The patent is about a method for producing a blended gaseous fuel that can be used in power plants or other manufacturing processes. This blended fuel is made by boosting the pressure of the compressed product syngas released from a buffer. The use of this blended fuel results in a reliable energy source that can be used in a variety of applications. The method utilizes a plasma or inductive furnace / plasma based gassifier system with efficiency-improving features such as pregassifiers and high turbulence plasma torch energy systems distributed on a metal pool to reflect energy, cause turbulence, and improve efficiency and financial viability. By blending natural gas or other fossil-based gaseous fuels with the product syngas from the gassifier, low NOx turbine combustors can operate successfully, which would be unreliable using pure syngas or liquid fueled flame pilot systems. The result is a commercially viable blended gaseous fuel that can be used in a variety of manufacturing processes.
Problems solved by technology
They have not had significant commercial success due to many reasons.
All of these conditions limit overall system thermal efficiency.
The steam Rankin cycle, although reliable, is well documented for its limited efficiency.
Such inefficiency results in poor financial performance relative to the required capital investment, and thereby constitutes a limitation on commercial success.
In operation, this system performs poorly.
This known arrangement is further challenged when a renewable non-homogeneous feedstock such as biomass or Municipal Solid Waste (MSW) is used.
Such an inconsistent fuel is poorly received when, as specified in that disclosure, “syngas is fed directly to a gas turbine.”
Overlooking the drawbacks of the above application in using the syngas fuel to operate a boiler hampered by the low efficiency issues of a Rankin cycle the known system also requires the cost and complexity of a dual fuel system, specifically a syngas fuel delivery system and a liquid fuel delivery system.

Embodiment Construction
[0042]FIG. 1 is a simplified schematic representation of a blended syngas co-fired arrangement 100 constructed in accordance with the principles of the invention. As shown in this figure, blended syngas co-fired arrangement 100 is provided with a gassifier 101 that has an inlet 113 for introducing a feedstock (not shown). In some embodiments of the invention, the feedstock is a renewable feedstock, such as MSW, a fossil fuel, or a hazardous waste (not shown). Any combination of the three forms of feedstock can be used in the practice of the invention. There is additionally provided an outlet port 102 via which the generated syngas (not shown) is removed. In embodiments in which the gassifier incorporates an inductive heat source, there is not provided an outlet for product as would be the case in a conventional inductive furnace (not shown) that would have a large outlet (not shown) for metal or alloy production. Instead, in the present embodiment of the invention, there is provided...

A method of generating a blended syngas as a primary product from renewable feedstock, fossil fuels, or hazardous waste with the use of a gassifier arrangement. The generated syngas is blended with natural gas to form a blended fuel product that is delivered to a manufacturing facility or a natural gas power plant.
