Exhaust 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 exhaust 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

1. Energy Performance Assessment of Boilers Bureau of Energy Efficiency 14. Fuel firing rate = 5599.17 kg/hr Steam generation rate = 21937.5 kg/hr Steam pressure = 43 kg/cm2(g) Steam temperature = 377 °C Feed water temperature = 96 °C %CO.

Mar 17, 2015· Using the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Steam Energy Flow = Specific Enthalpy * Mass Flow.

Jun 29, 2011· This paper identify the heating value of the coal into the boiler, aiming at the on-line calculation of the boiler efficiency, by means of the dynamic mass and energy balance method. Then an on-line calculation model for thermal efficiency of the boiler was established based on the indirect heat balance method.

Calculate the boiler heat balance on the dry basis for the data as follows Fuel ultimate analysis C = 71.81 N = 1.20 A = 821 H = 5.23 S = 3.34 O = 10.15 High heating value = 13, 082 Btu/lb Flue gas analysis CO_2 = 14.2 O_2 = 4.3 CO = 0.3 N2 = 81.2 Refuse w_r = 0.115 lb/lb of coal burned Flue gas temperature 463 F Fuel and room temperature 85 F Ambient relative humidity 50%

The time required to heat 75 kg of water (cp = 4.2 kJ/kgoC) from temperature 20oC to 75oC with steam produced from a boiler with capacity 200 kW (kJ/s) can be calculated by transforming eq. 2 to t = m cp dT / q = (75 kg) (4.2 kJ/kgoC) ((75 oC) - (20 oC)) / (200 kJ/s) = 86 s

File Size: 1MB Oct 19, 2019· It is written as “from and at 100°C”. 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 …

Heat gained by the cold side = Q = m C × Cp C × (To C - Ti C) …. (2) m H × Cp H × (Ti H - To H) = m C × Cp C × (To C - Ti C) …. (3) This energy balance equation can be solved for one variable for any given case. Out of total six variables in the equation (3), five should be fixed to determine the unknown variable.

Jun 02, 2017· Video contains working of a boiler with accessories such as superheater , economiser , air pre-heater. Explanation of calculation of heat balance sheet is done.

Sep 13, 2015· Thermodynamics boiler/steam generator, heat balance sheet explainaton - Duration: Weight and Balance Calculations (Private Pilot Mod-01 Lec-29 Material & Heat Balance …

Models for the required data for energy balance calculation, such as enthalpy of formation of combustion products, are also included. In order to carry out material and energy balance calculation, besides the heating value and composition of the fuels, the …
