Co-Combustion of Waste and/or Biomass by Fluidized-bed

Abstract

In this report, co-combustion of MSW(municipal solid waste) and Landfill waste, co-combustion of MSW and sewage sludge come up as examples of combustion of “Hybrid fuel”. MSW itself is also “Hybrid fuel” which consists of plastics, paper and kitchen waste, and so on. Though the composition and the calorific value of fuel (waste) are important factor to design and operate an incineration plant, these important factors are influenced by season, collecting area of waste, event such as “New year holidays”. For this reason, the operator usually cannot control of these important factors before feeding waste to a furnace. Fluidized-bed which is suitable for wide range of characteristics of waste is used for incinerator /gasifier of waste as “Hybrid fuel”, and advanced control systems such as “model based predictive control” and flue gas control logic by machine learning are applied to incineration system.
