(PDF) Boiler Efficiency Improvement and Energy Saving …Boiler Economizers. The Boiler Efficiency Calculator allows you to calculate the energy efficiency benefits of adding one type of economizer to a boiler system. Economizers are heat exchangers that transfer the heat in the flue gas to another medium‚ generally the boiler feed-water‚ although other streams are sometimes used such as make-up water.Boiler Economizers - NRCanBoiler economizer calculation A generally accepted "rule of thumb" is that about 5% of boiler input capacity can be recovered with a properly sized economizer. A higher percentage can be recovered with a Flue Gas Condenser, assuming there is enough cold water to condense all of the flue gas that is available.

Boiler Economizer Types And Efficiency Calculation--ZBGA 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.Chapter 14 Boilers - PearsonAn economizer is similar to the convection section in a direct-fired heater. Both oper-ate under the energy-saving concept of recovering some of the heat from the hot flue gases before they are lost out of the stack. The typical improvement in efficiency of a boiler
