Hydrogen: The Burning Question - Features - The Chemical

Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, 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.

Selective non-catalytic reduction involves the injection of a NOx reducing agent, such as ammonia or urea, into the boiler exhaust gases at a temperature of approximately 1400-1600°F. The ammonia or urea breaks down the NOx in the exhaust gases into water and atmospheric nitrogen. Selective non-catalytic reduction reduces NOx up to 70%.

Combine Cycle Gas-Fired Gas Turbine Emissions Test - EPA

27/05/1994 · The turbine exhaust gas flow rates used to compute mass emissions in units of lb/hr were determined using EPA Method 19 procedures and the measured flue gas O2. An on-line process gas chromatograph analyzes a natural gas sample every hour at the Wharton facility. The fuel analysis data supplied by the source are included in Appendix B.

varying load or excess air. However, the load at which a gas turbine operates can affect emissions of benzene, toluene, and formaldehyde, as well as hydrocarbons, CO, and NOx. EPRI Perspective . The emission results from this study will help utilities estimate and manage the trace substance emissions from gas-fired boilers and combustion turbines.

The exhaust gas temperature at the HRSG exit is maintained above the condensation temperature of combustion products. The steam conditions at the ST inlet are set at 8 MPa and 400°C, and the condenser pressure in the steam cycle is 0.10 bar. Ranges are considered for some system parameters, to allow sensitivity studies.

free escape of gas from a cylinder when the bursting disc is ruptured but not allowed to depress the oxygen level in the CO 2 room. Bursting discs which do not release gas into the discharge manifold should be piped to open air and not allowed to vent into the room. 7.3.1.2 . Non-return valves should be provided at the discharge manifold to
