The level of SOx emissions is not dependent on boiler size or burner design. Typically, about 95% of the sulfur in the fuel will be emitted as SO2, 1-5% as SO3, and 1-3% as sulfate particulate. Sulfate particulate is not considered part of the total SOx emissions. Historically, SOx pollution has been controlled by either dispersion or reduction.

High NOx emissions can occur when an engine's air-fuel mixture is too lean. This can happen when too much air is added to the fuel or when too little fuel is injected into the engine. In either case, this causes the mixture to burn hotter. This could be caused by a problem with the vehicle's oxygen sensor, malfunctioning air flow and coolant

2019-4-9 · In atmospheric chemistry, NO x is a generic term for the nitrogen oxides that are most relevant for air pollution, namely nitric oxide (NO) and nitrogen dioxide (NO 2 ).[1][2] These gases contribute to the formation of smog and acid rain, as well as affecting tropospheric ozone. NO x gases are usually produced from the reaction among nitrogen

The effects of flue gas recirculation ratio, air preheating temperature, oxygen concentration, and fuel types on pollutants emission in the volumetric combustion system were investigated. According to the results, it was concluded the higher substitution ratio of biomass in a co-firing boiler, the lower emissions of NOx and SOx.

While small and medium size biomass combined heat and power (CHP) plants (i.e., up to 5 MW of electrical rated power) represent an attractive option to exploit locally available biomass resources at low cost, the corresponding investment per unit of rated power significantly rises when the installed power decreases. In these cases, secondary pollutant emissions control measures are most of the
Get a quote For example, when calculating the annual emissions of a boiler, you need to look at the total amount of fuel consumed by that boiler in a one-year period. and a bag and filter house for particulate would differ from a wet scrubber controlling emissions of SOx. Hopefully we've demystified how to calculate air emissions, and we've

SOX quantity in the exhaust gas is twice the sulphur feed rate in the fuel. For example if we are using 100 tonnes of fuel per hour and fuel sulphur content is 2 % then feed rate of sulphur would be 2 tonnes per hour and if all of it burns then it will form 4 tonnes of SOX (64/32 ).
