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 economiser.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.Get Price
The inlet is subject to severe pitting, because it is often the first area after the deaerator to be exposed to increased heat. Whenever possible, tubes in this area should be inspected closely for evidence of corrosion. Economizer heat transfer surfaces are subject to corrosion product buildup and deposition of incoming metal oxides.Get Price
Economizer - A series of tubes located in the path of the flue gases. Feedwater is pumped through these tubes on its way to the boiler in order to absorb waste heat from the flue gas. Efficiency, Fuel - Efficiency, fuel refers to the heat absorbed divided by the net heat of combustion of the fuel as heat input, expressed as a percentage.Get Price
Straight tubes, shell-and-tube waste heat boilers undergo transgranular cracking due to uneven distribution of stresses by hot gases on the face of tubes and also known as corrosion fatigue failures. Design features that allow steam pockets to form are known to cause cyclic overheating and quenching. The economizer placed at flue gas exit Get Price
These types of boilers are most commonly utilized for applications that require low to medium steam pressure and a low rate of steam generation.
