Project funded by the National Centre for Research and Development under the LIDER VIII program.

Title: “Development of a Prototype System for Real-Time Measurement of Coal Dust Pulverization in Pulverized-Fuel Boilers” – POM-PY
Contract No.: LIDER/20/0119/L-8/16/NCBR/2017
Project Leader: Dr. Eng. Jarosław Smyła

Project Objective:
The aim of the project is to develop a prototype system that continuously determines the average particle size of flowing coal dust in the pipeline of a pulverized coal boiler installation leading to the burner. This proposed solution is a perfect match for market needs. In power plants and combined heat and power plants, there is an ongoing issue with achieving an even quantitative and qualitative distribution of coal dust with the appropriate granulation. Preparing fuel in a way that does not align with the boiler’s design specifications leads to an improper combustion process. Increasing regulatory demands for reducing emissions of harmful substances from coal-fired energy boilers, along with the drive to improve efficiency in electricity and heat production (thus reducing losses from the combustion of solid fuels), necessitate control over the process and continuous adjustment of various boiler and fuel parameters. Despite various attempts, there is currently no effective method globally for continuous measurement of this parameter.
This innovative approach involves integrating various measurement techniques with an intelligent algorithm. The system will measure parameters such as flow velocity, mixture density, electrostatic charge, and temperature. Based on these measurements, a suitable algorithm will be developed to enable the measurement of coal dust fineness.

Planned Outcomes:
The end result of the project will be an autonomous, real-time (online) monitoring system for coal dust fineness. Future application of this system in combustion process automation is expected to reduce fuel consumption in pulverized coal boilers and lower NOx emissions.

Project Value: PLN 1,186,135.64, including funding of PLN 1,186,135.64.
