the flue gas. These factors mean that some form of flue gas treatment may be required. Flue gas treatment for CO 2 capture 5 The major impurities in the CO 2flue gas stream are water vapour, nitrogen, oxygen and argon. SO 2, NO 2, HCl and HF are minor impurities. Mercury is present in trace amounts. Moisture has to be removed to avoid corrosion
However, it is noted that the flue gas volume per unit of supplied energy, S (m3/MJ), is essentially invariant for a given fuel type and this is a better basis for calculation when compared with the flue gas volume per unit mass. The flue gas volume is derived from the
Flue gas composition is significantly affected by the combustion conditions. Concentration of gaseous species upon firing 1.7% S coal (chemical composition is given in Table 1) was calculated at 1300 °C, assuming thermal equilibrium, and presented in Figure 2 as a function of airfuel ratio. In this chapter, airfuel ratio is defined by the ratio of their weights; airfuel ratio of 10
Chimney Draft Calculator. h - height of chimney (m) ρ o - density outside air (kg/m 3) t i - chimney inside temperature (o C) t o - outside air temperature (o C) Chimney Draft Chart. Chimney Draft Chart (pdf) Chimney Area. The velocity of air and flue gas in a smaller furnace should not exceed 2 m/s. Design velocities of larger furnaces should

Apr 16, 2004 · I need to calculate the mean specific heat capacity of a flue gas.Problem is, the flue gas is a product of oxy-fuel combustion with CO2 as a major component and rest being H20. The temperature of the combustion system varies from 1000 to 1400°c and pressure from atmospheric to 16 bar. Can you suggest me how I can calculate it.
App 1-7 HHV is the higher heating value, hg is the enthalpy in Btu/lb of water vapour at 1 psi and the flue gas temperature (FGT) in °F, and hf is the enthalpy of water at the combustion air temperature (CAT) in °F. hg can be determined from steam tables or from the equation hg, Btu/lb = 1055 + (0.467 x FGT). hf can also be determined from steam tables, or from the simple relationship
Total amount of dry flue gas per 1 kg wood = 4.872 m3. If the concentration in the wet flue gas is required then the water content has to be included in the above calculation. C + O2 = CO2 2H 2 + O2 = 2H 2O Oxygen required for stoichiometric combustion = 4.33+1.6−1.3 = 4.63kg-mol Air requirement = [4.63×100 ×22.41]/= 494.1 m3 at NTP
Dec 01, 2020 · For these gas utilization facilities, theoretical dry flue gas volume is the main content of combustion calculation, which is the basic work for the combustion system design. In current method, the calculation of theoretical dry flue gas volume is generally based on complete fuel composition ,
The flue gas leaves the boiler at 300oC (all the water formed will be vapour). In addition, a substantial amount of heat is also lost through the boiler wall and other uncounted sources. Calculate the flue gas composition (both dry and wet basis) leaving a boiler. Calculate the
from natural gas-fired boilers are flue gas recirculation (FGR) and low NOx burners. In an FGR system, a portion of the flue gas is recycled from the stack to the burner windbox. Upon entering the windbox, the recirculated gas is mixed with combustion air prior to being fed to the burner. The recycled flue gas
Supporting Calculations Combustion of natural gas. The stoichiometric combustion of natural gas is shown in the equation below. ( ) Eq-1 The number of moles of dry flue gas constituents is equal to the sum of the moles of N 2 and CO 2, 8.64 lbmols. Staff converted the flue gas constituents from a volumetric proportion to a mass proportion.
Jul 30, 2016 · 2. How do flue sizing charts work? A typical table from a gas standard gives a correct flue diameter for a 4% CO2 flue gas concentration. The table requires only the appliance heat input (or gas rate) and the height of the flue to be known. There is no indication of the heat loss of the flue, or the flue material. Has that been cancelled out
Flue Gas Properties Calculator This calculator Calculates the thermal properties for a flue gas when given the composition and temperature or enthalpy of the gas. Nitrogen, mole% = Oxygen, mole% = Carbon Dioxide, mole% = Water, mole% = Argon, mole% = Sulphur Dioxide, mole% =
and the weight of flue gas per pound of coal burned will be .80 × 23.42 = 18.74 pounds. The heat lost in the flue gases per pound of coal burned will be from formula and the value 18.74 just determined. Loss = .24 × 18.74 × (500 - 60) = 1979 B. t. u. The percentage of heat lost in the flue gases

Aug 02, 2007 · for every 15 lbs of fuel, you need 1 lb air. The lbs burned will be lbs carcus-lb ash + lbs fuel. Take that number multiply by 16 to get total lbs of flue gas. The lowest temperature you want to cool the flue gas is about 250 to 300 F, any lower and you will condense out all kinds of acids. So Q = (900F - 300F) * lbs * heat Capcity for N2 of .24.
