# specific heat of boiler flue gas

## Flue Gas Boiler - Waste Heat Boiler - Zhong Ding Boiler

Flue Gas boilers are the significant energy saving equipment, utilize the heat in flue gas from combustion processes or hot extract air from industrial processes to generate hot water or saturated steam Otherwise, the flue gas boiler could be used in oil gas fired combined cycle units, and take advantage of the high temperature flue gas heat discharged by gas turbine

## Fuels - Combustion Air and Flue Gas

1) Combustion of a fuel gas creates a flue gas with higher density than the fuel gas and the combustion air. Check stoichiometric combustion . 2) Volume at standard pressure

## Flue Gas Waste Heat Boiler Thermal Efficiency Calculati

The heat efficiency of a flue gas waste heat boiler is the percentage of the effective heat in the heat injected into the fuel. The anti-balance test method is usually used to measure boiler thermal efficiency. The calculation formula for the thermal efficiency of the anti balance method: η= 100- (q2+q3+q4+q5+q6) 1. q2-flue gas heat loss

14 rows· It is for following chemical composition: nitrogen N 2 - 76%. carbon dioxide CO 2 - 13%. water vapor H 2 O - 11%. Temperature [ O C] c p [kJ/kgK] ρ [kg/m3] μ*10 6 [Pa*s] ν*10 6 [m2/s]

## specific heat capacity of boiler flue gas | CFB pow

The enthalpy of the gas is the product of the mass, the mean Cp and the temperature difference. Thus, if you have the Cp's for the two temperatures2I assume you are asking for the correlations with numbers so you can make these calcs, will check my notes and get back to you athomas236I 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 majorbhupesh241: As far as computing the sensible heat or mean specifc heat of the flue gas for high gas temperatures, such as adiabatic flame temperatuIf your combustion is done with air the major contributor by volume to your product gases is nitrogen, not CO2. The specific heat values (cal/g.K)for dry air, CO, CO2, O2, N2 the heat capacity is around 0.22-0.24, but for H2O vapor the Cp is about 0.48, so the percent H2o by weight has the laPlease note that in industrial heaters adiabatic temperatures cannot be attained because of heat radiated in statu nascendi to the cooler surfacesBack to the original question, I have an old second year (or so) textbook with 'mean' specific heats of various components of flue gas. Essentiall Jan 17, 2019· Power 101: Flue Gas Heat Recovery in Power Plants, Part I. 2010-1-4 · Register Now to participate in this webinar: The role of mobile water treatment to offset emergency or scheduled plant shutdownsChapter 4.1: Boiler Short type questions – EM & EA2010-9-16 · Selected questions 3.

## Mean specific heat of flue gas - Energy engineeri

Apr 16, 2004· RE: Mean specific heat of flue gas. 25362 (Chemical) 14 Apr 04 08:18. If your combustion is done with air the major contributor by volume to your product gases is nitrogen, not CO2. The specific heat values (cal/g.K) aren't much affected by a pressure rise from 1 bar to 16 bar.

As the water is already at the boiling temperature, it requires only latent heat at 1.033 kg/cm 2 to convert it into steam at the temperature (100° C). The value of this latent heat is taken as 539.0 kcal/kg. Mathematically, Equivalent evaporation “from …

## Energy Content of Flue gas - Energy engineering gener

Aug 02, 2007· 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. rmw (Mechanical) 11 Jul 07 21:45

## Technology for Boiler System Efficiency Sponsor – Southe

The heat exhausted from a boiler is dependent on two factors: •Flue Gas Temperature (boiler specific) •Water Vapor Content (humidity) The excess combustion air and type of fuel burned determines the amount of water vapor (humidity) in the flue gas.

## ANALYSIS OF FLUE GASES - gutenberg.o

The heat lost in the flue gases is L = 0.24 W (T - t) (15) Where: L = B. t. u. lost per pound of fuel, W = weight of flue gases in pounds per pound of dry coal, T = temperature of flue gases, t = temperature of atmosphere, 0.24 = specific heat of the flue gases.

## Flue Gas Specific Heat Calculator • FG

You only need to know the mass of the flue gas and its temperature. Either measure the flue velocity with anometers, pitto tubes, or something. YouShouldn't the moisture content of the fuel be considered as a constituent of the flue gas mass? rmwWhy 900 0 C flue gas straight from the chimney (I presume)? You must be having a scrubber to remove suspended particles and the flue temperature drTo give you a ballpark idea, enthalpies of typical flue gases at this temperature level are in the vicinity of 320 kcal per normal (O o C and 1 atmThanks for the advise. Its very useful.Hi there: Here is an MS Excel spreadsheet that deals with combustion calculations for oil and coal type fuels and/or any combination of such fuels.Hello everybody: dcasto: If you assume an air-fuel ratio of 15, it means that for every 1 lb of fuel, you need 15 lbs of air. Or in SI units, for 1Yep, got the numbers backwards. Flue Gas Specific Heat Calculator. This flue gas specific heat calculator helps you to quickly estimate the specific heat of your flue gas. Several unit of measure available: kcal/ kg °C. kcal / kmol °C. kcal / Nm3 °C.
