Investigation of gaseous emissions and ash deposition in a pilot-scale PF combustor co-firing cereal co-product biomass with coal

Abstract

This study presents the results of investigations

into the gaseous emissions and ash deposition characteristics

from combustion of Cereal Co-product mixed with coal in a

100 kWth pulverised fuel combustor. Combustion gas emission

samples for CO2 , O2 , H2O, SO2 , CO, NO, NO2 , N2O, HCl, HF,

were obtained on-line by a high resolution multi-component

Fourier Transform Infra-Red gas analyser. Ash deposit samples

were collected from the flue gas using three air-cooled probes

that simulate heat exchanger tubes with surface temperatures of

500, 600 and 700 °C. The deposits formed were analysed using

SEM/EDX and XRD techniques to assess their corrosion

potential.
