As stated earlier, undiluted exhaust has about 0.5% O2 in it, so you should strive for that target – although less than 2.0% O2 is generally acceptable. Once you have reduced the O2 readings to less than 2.0%, you should also confirm that the sum of the CO and CO2 readings is close to 15% for Gasoline …
Oct 22, 2016 · We produce deduster more than 5000 sets of 35T-200T boiler heat center whole multitude dust remover and boiler desulfurization system devices per year, applying for the large paper-making, board and power plant industry.
CFM = the total volumetric flow rate of exhaust gases, gph = burner oil delivery rate in gallons per hour . Te = exhaust gas temperature which varies from the boiler outlet . temperature to gas temperature at chimney outlet, oF . b. Convert bend to its equivalent length.

exhauted gas flow rate calculation for boiler – CFBC
Application Note: Flue Gas Analysis as a Boiler Diagnostic Tool
Air Flow Rate Calculation (Flue Exhaust Gases). 1 volume of gas requires So 12.5 times the gas volume are approx exhausted from the chimney. Example,. 1,000 kW boiler operating at 90% efficiency gives burner firing rate of 1,099 kW. Furnaces
Are you conducting exhaust gas analyses on industrial engines, combined heat and power plants, gas turbines or boiler plants? Then an emission meter from Testo is ideal. Robust, modular and highly accurate, it ensures that emission limit values are adhered to and plants run efficiently.
