Pulverized coal burners Powerz

In burners of all three types, highdensity pulverized coal is injected through pipes (76 or 89 mm in diameter) with splitters at the end. Central and peripheral air passages have axial swirlers. Natural or coke gas is injected into burners via gas tubes loed in series between the adjacent air passages.

Pulverised Coal Combustion with higher efficiency

Producing electricity in coal power plants can take place in a number of ways with varying degrees of efficiency. In conventional coalfired plants coal is first pulverised into a fine powder and then combusted at temperatures of between 1300 and 1700 o C. This process heats water in tubes in the boiler so that it becomes steam at a pressure of around 180 bar and a temperature of 540 o C.
