Abstract
A reciprocating piston generator assembly that uses a low-concentration methane as a form of fuel comprises: a lean methane engine; a generator assembly; a fine water mist transmission system; a refrigerating dehydrator; an electric butterfly valve; a pressure regulator; a fuel-air mixer; a TEM controller; a heat load sensor; a combustion chamber for the lean methane engine; an air filter; and a speed governing butterfly valve, wherein the fine water mist transmission system is attached sequentially with the refrigerating dehydrator, electric butterfly valve and low-concentration methane engine; and the pressure regulator, fuel-air mixer, air filter, speed governing butterfly valve, heat load sensors and combustion chambers are installed in the methane engine; that the TEM controller is connected to the fuel-air mixer and heat load sensor; and the generator is connected to the low-concentration methane engine. This invention has been applied broadly in low-concentration methane coal mines and other similar fields due to its favored properties; such as high heat-recovery efficiency, lessened water consumption, energy savings, emission reduction and environmental protection.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
