Thermal processing of waste represents not only waste disposal including reducing its volume but also waste to energy process. This is the case in most to date municipal solid waste (MSW) incinerators. It is necessary to analyze all feasible ways how to utilize energy as much as possible which actually means recycling in terms of energy.
The work focuses on one of the up to date MSW incinerators with throughput of 12 t/h which belongs to waste to energy category. The energy released during thermal oxidation of waste is utilized for generation of high pressure process steam and also for co-generation. The majority of produced steam is exported and sold outside the plant. The remaining amount is used inside the plant for covering the heat requirements e.g. preheating the primary air, heating the boiler feed water. A decrease of the in-house energy provides an additional potential to export the steam and to improve overall economy of the plant.
Conventional methods of energy availability are discussed in the paper and analyzed. Heat flows in the incineration plant, Plant Efficiency Factor (PIef) and Energy Utilization Rate (e) are evaluated. An alternative approach considering heat integration and utility system is investigated. The evaluations are based on industrial data from the incineration plant monitoring system. Newly developed WTE software for simulation of waste to energy systems (a product of UPEI-VUT Brno) and software code SPRINT for process integration (a product of CPI UoM) have been applied, and the results analyzed. The potential energy savings identified by simulation are confronted with the MSW incinerator plant production constraints. The suggestions for the improvement acceptable by the plant are the key deliverables.
