Gasification of a municipal solid waste in a pilot scale bubbling fluidized bed reactor

摘要

1. A gasification based, small-scale waste-to-energy plant, having a nominal throughput of 5000 t/y of a Secondary Recovered Fuel obtained from unsorted residual waste, has been investigated. 2. The technical performances of a heat gasifier configuration of this plant have been quantitatively assessed. Mass and energy balances of the proposed plant were based on the experimental data obtained from a pilot scale bubbling fluidized bed air gasifier. 3. An innovative mild combustion system has been pro posed to burn the syngas and has been coupled with an Organic Rankine Cycle generator. 4. The results, together with those of a preliminary economic analysis, indicate that the proposed plant configuration, including a bubbling fluidized bed reactor, a mild combustion system, a 400kWe ORC generator and a simple air pollution control system, appears fully sustainable.
