Having an indication of changes to the heating value of municipal solid waste (MSW) and having a means to control it before the MSW is fed to the boiler enables improved combustion control and increased capacity of waste-to-energy boilers. The moisture content of MSW has a significant impact on its heating value and on boiler efficiency when combusted. Changes in moisture content also change the density of the MSW. Directly measuring the density of the MSW prior to feeding it to the boiler permits controlled addition of additional water or liquid waste to reduce the variance of the MSW heating value.
Une indication concernant les changements à apporter à la valeur de chauffage de déchets solides municipaux et un dispositif destiné à les maîtriser avant leur acheminement jusqu'à la chaudière permettent d'améliorer la régulation de la combustion et d'augmenter la capacité des chaudières de production d'énergie à partir de déchets. La teneur en humidité des déchets solides municipaux a un impact important sur leur valeur de chauffage et sur l'efficacité de la chaudière, lors de leur combustion. Des changements de la teneur en humidité modifient alors la densité desdits déchets. La mesure directe de la densité des déchets solides municipaux avant leur acheminement dans la chaudière permet d'ajouter de manière régulée de l'eau ou des déchets liquides supplémentaires afin de diminuer la variance de la valeur de chauffage desdits déchets.
