    Superheaters - an overview | ScienceDirect Topics

    Superheater type, design, material, and construction methods always involve compromise to achieve the desired technical level at low cost. The wall superheater is a special class of superheater. Sometimes part of the superheating surface needs to be located at the furnace proper. The wall superheater surface is used in these applications.

  • corrosion of superheaters and reheaters in fossil fired

    Corrosion of Superheaters and Reheaters in Fossil Fired

    The corrosion of superheaters and reheaters in fossil fired boilers can be related to both fire and steam side conditions. Oil fueled boilers exhibit ash corrosion by low melting point slags of vanadium, sodium, and sulfur oxides, coal fired boilers by complex sulfates. In both cases, increasing tube metal temperature exacer- bates corrosion rates.

    The most accepted method of measuring boiler efficiency is the "heat loss" method. Most Eastern Bituminous coal fired utility boilers are capable of around efficiency. It should be pointed out that 90% boiler efficiency can be maintained — yet unit heat rate penalties experienced at that given time may represent more than — or about 200 BTU

    How to Run a Coal Fired Boiler at the Best Efficiency

    Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss. There are a few minor losses in boiler which can also
