Abstract

Large combustion plants generate > 100 MW power as their primary function. They were not designed to utilise waste as fuel, so they do not utilise it as their primary fuel and operate at higher steam parameters than purely waste- fired units. The main options for firing waste are: direct solid waste firing in pulverised-coal (PC) boilers, direct firing of solid waste in large fluidised-bed boilers, firing waste gasification gas in PC boilers and converting PC boilers to waste-firing fluidised-bed boilers. Each option has been demonstrated at a large scale, some plants having been in commercial operation for many years. The plants have a high power-to-heat ratio and they require pre-treatment of the waste.
