An innovative oxyhydrogen (HHO) burner system including one or more burner systems is provided to eliminate emissions through total combustion. Each burner system includes at least one HHO gas supply and an external natural gas supply, both of which are connected to a gas mixer. A controller regulates the amounts of incoming HHO gas and the natural gas through being mixed. The mixed gas is supplied to each burner assembly with a predetermined pressure and flowrate to generate a flame for the total combustion of the exhaust stream inside the exhaust pipe. With feedback from an exhaust measuring system inside the exhaust pipe adjacent the outlet, the controller can adjust the burner system for optimal operations and achieve total combustion. Thus, by passing the exhaust or gases through a substantial cross-section covered by each flame, emissions can be greatly reduced or eliminated.

The present invention relates to a device for cleaning exhaust gases from a fireplace, comprising a housing which accommodates functional components of the device, an inlet portion provided to receive exhaust gases from the fireplace, an outlet portion provided to discharge exhaust gases from the device, a bypass portion which is configured to establish a direct connection between the inlet portion and the outlet portion and which can be closed by means of a first mechanical flap arrangement, and a cleaning portion which extends between the inlet portion and the outlet portion for guiding an exhaust gas flow and is provided with a plurality of functional components, wherein the functional components at least comprise an electrostatic filter unit for separating fine dust particles, a centrifugal separator unit for removing particles from the exhaust gas, and a fan unit for driving a flow of the exhaust gas through the cleaning portion.

A CO.sub.2 separation system configured to separate CO.sub.2 from mixed gas containing CO.sub.2 includes a CO.sub.2 separator, a CO.sub.2 collector, and a pressure difference generator. The CO.sub.2 separator includes a separation membrane configured to separate the CO.sub.2 from the mixed gas, and a separation-membrane upstream chamber and a separation-membrane downstream chamber demarcated by the separation membrane. The CO.sub.2 separator is disposed to cause the mixed gas to flow into the separation-membrane upstream chamber. The pressure difference generator includes at least a negative pressure generator. The negative pressure generator is disposed on a gas path of the permeating gas that connects the separation-membrane downstream chamber and the CO.sub.2 collector.

A system comprising a collocated thermal plant, water source, CO.sub.2 source and biomass growth module is disclosed. A method of improving the environment by utilizing the system is disclosed.
