EMAG started the POM-PY project

On January 2nd, the Institute of Innovative Technologies started a project entitled: Developing a prototype of the system for current measurement of the degree of pulverized coal dust in pulverized coal boilers under the acronym POM-PY. The project was financed by the National Center for Research and Development as part of the LIDER VIII program.
The aim of the project is to develop a prototype of a system that continuously determines the average size of the hard coal dust particle flowing towards the furnace in the pipeline of the combustion instalation of the pulverized coal boiler. The proposed solution perfectly meets the market needs.
In power plants and heat and power plants there is a problem of even quantitative and qualitative distribution of dust with appropriate granulation. The preparation of fuel which is inconsistent with the boiler design leads to an incorrect combustion process. This process has to be monitored and many parameters of the boiler and the fuel have to be regulated on-line. There are several reasons to do that. The first are the growing requirements concerning the emission to the environment of harmful substances produced in coal-fired boilers. The second is striving to increase the efficiency of the electric and heat energy generation, and thus reducing fuel combustion losses. Despite various attempts, the world lacks an effective method for continuous measurement of this type of a parameter. An innovative approach to the issue is based on the integration of various measurement techniques with the use of an intelligent algorithm. The following measurements are assumed: speed of the mixture flow, density of the mixture, electrostatic charge and temperature. Based on the above measurements, an appropriate algorithm for measuring pulverized coal dust will be prepared. The work should result in an autonomous system for on-line monitoring of the coal dust pulverization degree. The future use of the system in automation of the combustion process will reduce the fuel consumption in pulverized hard coal boilers and the emission of NOx.
