M&W JAWO HANDLING AS
 
 
   

M&W JAWO Handling raw coal sampling system is an integrated part of the control system available to the power plant operators. The sampling system provides the operator with the means of executing the extraction and preparation of representative samples of the coal. The sample size is suitable for making laboratory analysis.

The M&W JAWO Handling raw coal sampling system operates in accordance with approved international standards.

The results of the laboratory tests performed on the basis of the representative samples prepared by the sampling system are used for: 

  • Calculating the payment due for each batch of coal supplied
  • Adjusting the coal flow to the mills
  • Calculating the amount of by-products from each batch of coal
  • Calculating the emissions from each batch of coal
  • Calculating the blending of various coal batches to obtain maximum output from the power plant

 

   
Modular Sampling System  
   
M&W Jawo Handling has developed a module-built sampling system, especially for sampling of cement clinkers.

The system consists of a chain bucket sampler, which is adjusted individually, and of various modules such as vibrating feeders, crushers, dividers, mills, mixers and blowers for return of reject material. Apart from this also service platforms are offered.

In addition to the above, the system can be connected to e.g. a pipe system for delivery of the sample directly to the laboratory. This sample will typically be approx 0.2 liter with a grain size of less than 200 micron.

AUTOMATIC COAL FLOW MONITOR  
   

The patented ACFM-2200 is a fully automatic on-line sampling and monitoring unit. It provides real time data for better combustion performance and fuel economy.

The technology is based on ISO 9931 isokinetic and representative extraction of samples in fuel pipes between the mills and burners. 

Samples taken are returned into the fuel pipe or at preset times collected in exchangable containers as per requirement. 

The flow measuring results are electronically transmitted to the control room monitors.

AUTOMATIC DUST SAMPLER  
   

The ADS is an instrument for extracting samples of ash in flue gas. The ADS operates automatically during all operating conditions and continuously provides samples for evaluation of the boiler efficiency.

Principal and process features:  

  • Continuous sampling
  • Durable, non-mechanic sampling device
  • Minimum of maintenance and supervision required
  • Easy to install and simple to use
  • All vital parts are manufactured from stainless steel

AUTOMATIC TRIMMING DAMPER  
   

The ATD is an electric driven valve trimming the flow of coal in the fuel pipes from the mills to the burners.

The ATD is flanged into the fuel pipe.

On receipt of an electric signal the damper will operate in the direction of openning or closing.

The opening/closing flaps are made from special wear resistant material.

The signal to operate the trimming damper can be generated "manually" from a push button or automatically from a communication box translating actual flow measurements from the flow monitor into signals for the ATD for the purpose of balancing the flow in all feeder pipes.

FLY ASH SAMPLER  
   

The FAS is an automatic sampling device, used for collecting dust samples in transport pipes, where the ash is conveyed pneumatically.  

The fly-ash sampler can be installed directly in the transport pipe or in the pneumatic transport hopper.  

  • The FAS is a very reliable and low maintenance instrument, with a sampling device manufactured from stainless steel
  • The FAS is automatically collecting samples at pre-set intervals
  • The samples are accumulated in an exchangeable container

PULVERIZED FUEL SAMPLER  
   

The Pulverized Fuel Sampler (PFS) is a portable instrument designed for sampling and flow measuring of pulverized coal in the fuel pipes between mills and burners. The Pulverized Fuel Sampler complies with the ISO 9931 standard for sampling of coal conveyed by gases.

The Pulverized Fuel Sampler is introduced into the fuel pipe through an airlock (Dustless Connection), and the coal sample is collected in an exchangable container attached to the sampler. 

Application areas:

  • Extracting of isokinetic and representative samples for determining of particle size of coal and other parameters.
  • Routine and special measurements of coal flow in fuel pipes.

PULVERIZED FUEL SAMPLER - AUTOMATIC  
   

The  PFS-A is a portable instrument designed for sampling and flow measuring of pulverized coal in the fuel pipes between mills and burners, according to ISO 9931.

The sampler is introduced into the fuel pipe through an airlock (Dustless Connection), and the coal sample is collected in an exchangable container attached to the sampler. The sampling probe is connected to an electric motor which enables it to rotate. A PLC in the control box ensures isokinetic extraction, and calculates the coal flow in the pipe.
The PFS-A is operated by only one person.

Application areas:

  • Extracting isokinetic and representative samples for determining of particle size of coal and other parameters.
  • Routine and special measurements of coal flow in fuel pipes.

RESIDUAL CARBON ANALYSER  
   

The RCA 2000 is an on-line analyser for carbon content in ash or LOI. The instrument provides the operator with vital real time information about the combustion efficiency through continuous monitoring of the unburned carbon content in the fly-ash.  

The technology is based on extracting samples of fly-ash in flue gas ducts. The samples are returned into the flue gas duct or can at preset times be collected in exchangable containers as per requirements.

The RCA 2000 is a very reliable instrument with low maintenance requirements. It reduces to a great extent the need of performing the labour intensive laboratory analysis.

The RCA 2000 will assist the operator in improving the operation in the following areas: 

  • Combustion efficiency
  • Emission reduction
  • Coal mill performance
  • Production of high quality fly-ash for sale
