Economizer - Wikipedia

The first successful economizer design was used to increase the steam-raising efficiency of the boilers of stationary steam engines.It was patented by Edward Green in 1845, and since then has been known as Green's economizer.It consisted of an array of vertical cast iron tubes connected to a tank of water above and below, between which the boiler's exhaust gases passed.

Flue Gas Recirculation (FGR) - CCA Combustion Systems

Flue Gas Recirculation (FGR) is a powerful nitrogen oxide (NOx) control technique that significantly reduces NOx emissions by recirculating flue gases from the boiler exhaust duct into the main combustion chamber. This process reduces peak flame temperature and lowers the percentage of oxygen in the combustion air/flue gas mixture, thereby reducing thermal NOx formation.

Heat-Recovery Steam Generators: Understand the Basics

lected for a particular case or exhaust gas condition called the "design case." Unlike in a conventional steam generator, where the steam demand drives the design case, in a HRSG steam production is affected by the conditions of the exhaust gas leaving the gas turbine (such as flow rate, temperature, and gas analysis) and entering the HRSG.Published in: Chemical Engineering Progress · 1996Authors: V GanapathyAbout: Combined cycle · Heat recovery steam generator · Superheater · Heat recovery ventilExhaustive research accurate flue design for commercial https:// boilers and gas-fired condensing boilers are good examples of plants that need accurate flue design to support their efficient functioning.
