» The Transportation of Natural Gas NaturalGas

The gathering system consists of low pressure, small diameter pipelines that transport raw natural gas from the wellhead to the processing plant. Should natural gas from a particular well have high sulfur and carbon dioxide contents (sour gas), a specialized sour gas gathering pipe must be installed.

Roll Crusher

Roll Crusher

The roll speed must be sufficient to prevent stalling, but not so fast that the coal is violently thrown out of the mill. Roll crushers most commonly have either one or two rolls, as shown in Fig. 9.3 ( Meyers, 1981 ; Jeffrey, 2011; McLanahan, 2011 ); Stedman, 2011 ), although some may use three or even four rolls in a two-stage crushing system ( Alderman and Edmiston, 2010 ).

The fineness of the coal powder and the uniformity of the coal flow sent to the burners are crucial parameters to achieve an effective combustion in coal-fired power plants. Coal pulverisers or coal mills are the heart of a PCF boiler. Often, the root causes of non-optimised combustion lie with the pulverisers.
