Installation of Air-Preheater and Economizer in Boiler

Air Preheaters (APH) is the Shell and tube type Heat Exchangers used for preheating the air which is fed to the boiler or furnaces/kilns for combustion of fuels. Air Pre heater's primary objective is to extract the waste heat from the flue gases leaving the boiler.

Air Preheater – Qingdao shengli boiler Co. Ltd

The function of air preheater is to transfer the heat from the flue gas discharged from the tail flue of the boiler to the air before entering the boiler through the radiator, and preheat the air to a certain temperature, so as to improve the thermal efficiency of the boiler system. Air preheaters are mostly used in coal-fired utility boilers.

Oxygen treatment for super critical power plants

Oxyfuel CCS power plant operation. Oxy-fuel combustion is the process of burning a fuel using pure oxygen, or a mixture of oxygen and fuel gas, instead of air. Since the nitrogen component of air is not heated, fuel consumption is reduced, and higher flame temperatures are possible. Historically, the primary use of oxy-fuel combustion has been in welding and cutting of metals, especially steel, since oxy-fuel …
