Supply Of Boiler Coal

Steam House Africa - boilers, burners and spares

Feb 24, 2012 · While the coal is fed to the boiler furnace in a pulverized form, the temperature of the coal is first raised to its ignition point the volatile matters of the coal so called hydrocarbons, such as marsh gas, tar, pitch, naphtha are separated from the coal and driven of in the gaseous form. These gases then combine with oxygen of air which is supplied through the bed of the hot bed of fuel

Pulverized coal-fired boiler - Wikipedia

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).

Fuel used in the boiler should be combusted completely to get complete heat of fuel. Due to low oxygen supply or uneven oxygen supply there may be changes of incomplete combustion of fuel. Incomplete combustion will reduce boiler efficiency drastically, it must be checked regularly and controlled by proper combustion system.

Dec 04, 2008 · Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2. The second stage is the thermodynamic process. The heat from combustion of the coal boils water in the boiler to produce steam. In modern power plant, boilers produce steam at a high pressure and

Conversion of Existing Coal-Fired Boilers to Natural Gas

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
