Waste Heat Recovery for PC Boilers
Pulverized coal fired boilers of medium to high capacity ranges (50 – 540 MWt) remain standard sources of energy for power plant and heat and power plants. Despite their maturity in design and operation, their big combustion chamber and high flue gas fluxes, configuration of auxiliary devices right after boiler exit make it difficult to fulfill new regulations in terms of emissions ( Directive IED – Industrial Emissions Directive) and provide highest efficiency standards.
In line with the above, the WasteHeat project aims at:
- Development and implementation (pilot and proof of concept) of patented but yet not tested in full-scale reality, solution of waste heat recovery at the tail of pulverized coal fired boiler which translates itself into efficiency gain and lowering of emissions.
- Estimation of market potential for the above mentioned technology.
The technology will be implemented and tested at existing pulverized coal fired boiler in CHP plant. The boiler under consideration is a coal and biomass pulverized fuel fired unit generating electrical energy and hot water for district heating with the capacity of 260 MWt.
Currently the project is undergoing WP0 procedure, i.e. feasibility study.

WasteHeat will deliver the following product:
Patented but yet not tested in full-scale reality, solution of waste heat recovery at the tail of pulverized coal fired boiler which translates itself into efficiency gain and lowering of emissions. This technology recovering the waste heat, which is irreversibly lost in flue gases from pulverized fuel fired boilers, is strongly recommended for implementation in power and combined heat and power generation plants in order to increase efficiency and also in CO2 reduction aspect.
