A boiler plant incorporates and economizer and air preheater and generates steam at 40 bar and 300oC with fuel heating value of 33000 kg/hr. The temperature of feedwater is raised from 40oC to 125oC in the economizer and the flue gases are cooled at the same time from 395oC to 225oC.
So in this way, we experience increased heat transfer and increase fuel saving by 1 %, this also will give maximum boiler efficiency.Fig. 1 :1First case of economizer Fig. 2: Second case of economizer Table - 1-Acid dew point for common fuel types fuel Acid dew point temperature Allowable exit stack temperature( • c) Natural gas 66 120
2018-9-17 · EFFICIENCY OF STEAM GENERATOR ECOMOMIZER AT DIFFERENT LOADS ION DOSA1, BOGDAN TOMU 2 Abstract: The economizer of a steam boiler is an important component that influences its efficiency. The link between steam boiler efficiency and economizer
This is the calorific value of the fuel, excluding the energy in the steam discharged to the stack,and is the figure generally used to calculate boiler efficiencies. In broad terms: Accurate control of the amount of air is essential to boiler efficiency: Too much air will cool the furnace, and carry away useful heat.
2014-3-4 · Performance of supercritical boiler: 1. Efficiency calculation of boiler: There are two methods to calculate the efficiency of boiler. That is, Heat loss method and heat input-output method. To calculate the efficiency of boiler correctly we use heat loss method.
2017-9-26 · Economizer Exit Gas Data: Ma Fuel flow and heat input are not used to calculate boiler efficiency, but are necessary for calculation of air and gas flows. OR Group C: For non-reheat units, enter all of the following: Fuel Flow determination will attempt to access Group A data first, Group B data second, and Group C data last.
An economizer that recovers 5% of boiler input should easily have a 2 year payback in a year-round application. More Information. Flue Gas Condensers. Exhaust Draft Control. Boiler Efficiency.

Can any help with how to select Boiler Flue Gas Economizer, and how to calculate gas out temperature and water in to feed tank? Thanks. RE: Boiler Flue Gas Economizer Calculations davefitz ( extended surfaces need to include a fin
boiler efficiency calculation excel sheet FBC Boiler Superheated steam at boiler outlet, tonnes, °C 116, The spreadsheet uses these values to calculate the specific enthalpy associated with heating the air from Stack economizer calculator Nicor Gas Rebates The spreadsheet does not calculate savings for condensing economizers.
2021-3-13 · Calculate the Boiler efficiency if it requires 25 TPH (Q3) attemperator water at temperature 125 deg C. Consider feed water temperature at economizer inlet is 210 deg C & ignore blow down loss. Boiler efficiency = (Steam generation X Enthalpy –(Feed water at flow X Enthalpy + Attemperator water X Enthalpy)) X 100 / (Coal consumed X Coal GCV)
2016-12-6 · boiler efficiency that cause most losses in normal operation. The "combustion efficiency" test determines how completely the fuel is burned, and how effectively the heat of the combustion products is transferred to the steam or water. The efficiency of the other boiler plant components, such as pumps, fans, and motors, tends to remain
2020-8-5 · Stack economizer calculator Boiler Feedwater Flow Rate (GPM) Actual savings will vary, and depend on other factors not considered in these calculations. Nov 22, 2011 The Boiler Efficiency Calculator allows you to calculate the energy efficiency benefits of adding one type of economizer to a boiler
Boiler Economiser: Boiler Economiser ( Sometimes Called Economizer ) is the Energy improving device that helps to reduce the cost of operation by saving the fuel.. The economizer in Boiler tends to make the system more energy efficient.. In boilers, economizers are generally Heat Exchangers which are designed to exchange heat with the fluid, generally water.
Boiler efficiency depend on the proper combustion of fuel, effectiveness of Heat transfer, operation and maintenance. Thermal efficiency of boiler is defined as the percentage of heat input that is effectively utilised to generate steam.
