61859 results about "Exhaust gas" patented technology

Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline, petrol, biodiesel blends, diesel fuel, fuel oil, or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack, or propelling nozzle. It often disperses downwind in a pattern called an exhaust plume.

Inductively coupled plasma spectrometer for process diagnostics and control

The present invention relates to an apparatus and method for forming a plasma in the exhaust line of a primary process reactor. The plasma is generated in an inductive source (5) to examine the chemical concentrations of the waste or exhaust gas in vacuum lines that are below atmospheric pressure. The optical radiation emitted by the plasma is analyzed by an optical spectrometer (9) and the resulting information is used to diagnose, monitor, or control operating states in the main vacuum vessel.

Combined patient interface and exhaust assembly

A combined patient interface and integrated exhaust assembly that passes a controlled flow of gas from an interior of a patient interface to ambient atmosphere at a predetermined flow rate irrespective of variations of pressure in the interior of the patient interface device relative to ambient atmosphere. Control of the flow of exhaust gas is achieved by varying the effective cross sectional area of the exhaust path communicating the interior of the patient interface with ambient atmosphere based on the pressure in the interior of the patient interface relative to ambient atmospheric pressure.
