Increased combustion performance

Flow Measurement & Control

November 2013 Flow Measurement & Control

M&W’s ACFM-2200 is a fully automatic coal flow monitor which collects pulverised coal samples from pneumatic transport pipes between mills and burners. It provides increased combustion performance and fuel savings. The measured results are transmitted to the control room for evaluation and control of the coal flow. The sampling operation is carried out according to the international ISO 9931 standard.

Typical applications include routine flow measurements, adjustment of fuel distribution, sampling of coal, monitoring of pulverising distribution settings in connection with low-NOx burners, and test firing of new coal types.

The sampling unit consists of a motorised rotating sampler arm with four coal extraction nozzles. The measuring unit separates the coal particles from the extracted gas stream and collects them in a measuring tube where the volume is measured by a fibre optics measuring device.

The control unit supervises the function of all components and converts the measuring signals for display on the operator’s panel. Facilities for remote indication are available. The operator’s panel allows easy access to mode selection and change of parameters, as well as display of error messages. The control unit can operate up to eight sampling and measuring units according to requirement.
