Components Of A Coal Fired Boiler

Natural Gas Fired Boilers

The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and

Boiler Efficiency - an overview | ScienceDirect Topics

The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.

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.

How Does a Coal Power Plant Work? - Bright Hub Engineering

On coal-fired boilers, several kinds of deposit may be formed: slag type, alkali-matrix type (bonded), and the phosphate type, only obtained from coals with a high phosphate content (see Chapter 20). Alkali compounds and phosphates are volatilized and condensed on cooler metal surfaces; the alkalis react with sulphur dioxide and sulphur trioxide forming sulphates which bond to the metal and pick up fly-ash on their molten surfaces and phosphates …
