Abstract
A method and system for cost-effectively converting a feedstock using thermal plasma, or other styles of gassifiers, into an energy transfer system using a blended syngas. The feedstock is any organic material or fossil fuel to generate a syngas. The syngas is blended with any fuel of a higher thermal content (BTU) level, such as natural gas. The blended syngas high thermal content fuel can be used in any energy transfer device such as a boiler for simple cycle Rankine systems, an internal combustion engine generator, or a combined cycle turbine generator system. The quality of the high thermal content fuel is monitored using a thermal content monitoring feedback system and a quenching arrangement.
Claims22
A method of extracting energy from a gassifier, the method comprising the steps of:
- delivering a feed stock product to the gassifier, wherein the feedstock comprises a municipal solid waste, wherein the feedstock is compressed to minimize the introduction of air, wherein the gassifier is inductively heated and wherein the gassifier is plasma assisted, and wherein the gassifier uses a pyrolysis method along with the inductively heated and plasma assisted process to create a fuel product;
- extracting the fuel product from the gassifier, the extracted fuel product having a first thermal content characteristic, wherein the extracted fuel product is extracted syngas, wherein the extracted fuel product is configured to comprise a consistent BTU content from a variable feedstock composition;
- injecting a portion of the extracted syngas in to the gassifier to chemically boost a heat of the gassifier;
- delivering the extracted fuel product to a fuel blending system;
- monitoring the thermal content of the extracted syngas and measuring the thermal content of the extracted syngas with the use of a thermal content measuring device;
- mixing a further fuel product comprising natural gas, wherein the further fuel product has a second thermal content characteristic with the extracted fuel product in the blending system, the second thermal content characteristic corresponding to a higher thermal content than the first thermal content characteristic, to form a blended fuel product of greater quality than the extracted fuel product issued by the gassifier, wherein the blended fuel product is a blended syngas product;
- and
- controlling a final thermal content of the blended syngas product in response to said step of measuring the thermal content of the extracted syngas, wherein the final thermal content is controlled to maintain a determined fuel quality with at least a minimum BTU.
A method of extracting energy from a plasma gassifier, the method comprising the steps of:
- delivering a feed stock product to the gassifier, wherein the feedstock comprises at least one of a renewable feedstock or a municipal solid waste, wherein the feedstock is compressed to minimize the introduction of air,
- extracting syngas from the plasma gassifier, wherein the plasma gassifier is inductively heated and wherein the gassifier is plasma assisted, and wherein the gassifier uses a pyrolysis method along with the inductively heated and plasma assisted process to create the extracted syngas, the extracted syngas having a first thermal content characteristic;
- injecting a portion of the extracted syngas in to the gassifier to chemically boost a heat of the gassifier
- delivering the extracted syngas to a fuel blending system;
- monitoring the thermal content of the extracted syngas and measuring the thermal content of the extracted syngas with the use of a thermal content measuring device;
- mixing a further fuel product comprising natural gas, wherein the further fuel product has a second thermal content characteristic with the extracted syngas in the blending system, the second thermal content characteristic corresponding to a higher thermal content than the first thermal content characteristic, to form a blended syngas fuel product of greater quality than the extracted syngas;
- and
- controlling a final thermal content of the blended syngas fuel product in response to said step of measuring the thermal content of the extracted syngas, wherein the final thermal content is controlled to maintain a determined fuel quality with at least a minimum BTU.
