Abstract
The composition of municipal solid waste (MSW) influences the incineration
process. The high heat value of some materials contained in the waste and their
moisture content affects the capacity of the process. In particular, the plastics
presence negatively affects the incineration process: an increase of calorific
value means a reduction of the capacity of the incineration plant. The throughput
of the incinerator can be limited for both purely mechanical reasons and by
thermal and mechanical overload. The thermal stress can be calculated starting
from the calorific value of the waste fed to the incinerator. In this paper,
innovative measurements of calorific value and hydrogen content of MSW fed to
incinerators have been carried out, in order to improve the technical operation of
incineration plants. A calorimetric bomb was used for waste heat measurements
and a neutron probe analysis was tested for hydrogen content determination in
waste. Measurements have been carried out on different typologies of household
waste products characteristics of four towns in the Netherlands. A special waste
sample holder was designed and different detection architectures based on
neutron sensing techniques were utilised to perform hydrogen content analysis.
Starting from the results achieved in this study the possibility to regulate the heat
value of the waste and its combustion in order to optimize the incineration
process has been envisaged.
Keywords: incineration, calorific value, hydrogen content, municipal solid
waste, neutron probe.
