For example, the calculation of the total annual NOx emissions for an 800 hp boiler operating 24 hours/day, 365 days/year and having a NOx level of 110 ppm would be as follows. Emission Factor = 0.13 lb/MMBtu (110 ppm = 0.13 lb/MMBtu) Boiler Input = 33.5 MMBtu/hr (Based on 80% Efficiency)

• ### CHAPTER 3 COMBUSTION CALCULATION

Sep 20, 2012 · SO2 (mg/Nm3) = (21 - O2ref/21 - O2) x SO2 (ppm) x 2.86. The conversion factors used in the formula come from the density of the gas components at standard conditions (O2ref take 6% and O2dry usually 4.5%). So we can say total sulfur gas production 0.247 ft3 or 753 PPM or 1924 mg/Nm3.

• ### Sulfur dioxide weight to volume conversion

Combustion of fuel release flue gases which is a mixture of Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide, H 2 O Vapor, Nitrogen or Nitro-Oxides, Oxygen and ash particles. The quantity of flue gases is also calculated using stoichiometry calculation when air reacts with the fuel. You can also refer to Thermodynes Boiler Bible that provides you the general composition of above elements for various

• ### 1.4 Natural Gas Combustion - US EPA

Emissions of SO2 from natural gas-fired boilers are low because pipeline quality natural gas typically has sulfur levels of 2,000 grains per million cubic feet. However, sulfur-containing odorants are added to natural gas for detecting leaks, leading to small amounts of SO2 emissions. Boilers combusting unprocessed natural gas may have higher SO2 emissions due to higher levels of sulfur in the natural gas.
