This paper presents an experimental study of the heating value of medical waste using an input-output method. The study was carried out at the Oncological Hospital in Bydgoszcz, Poland, over a period of three months. The installation for thermal treatment consisted of a loading unit, a combustion chamber, and a discharge chamber (thermoreactor). The medical waste constituted the primary fuel, a...

The gross calorific value (GCV) or heating value of a sample of fuel is one of the important properties which defines the energy of the fuel. Many researchers have proposed empirical formulas for estimating GCV value of coal. There are some known methods like Bomb Calorimeter for determining the GCV in the laboratory. But these methods are cumbersome, costly and time consuming. In this paper, m...

BACKGROUND Microwave heating is one of the most attractive cooking methods for food preparation, commonly employed in households and especially in restaurants for its high speed and convenience. The chemical constituents of oils that degrade during microwave heating do so at rates that vary with heating temperature and time in a similar manner to other type of processing methods. The rate of qu...

Accurately and efficiently predicting the LHV of MSW is vital for designing operating a waste-to-energy plant. However, previous prediction models possess limited geographical applicability. In this paper, we employ multiple linear regression artificial neural network (ANN) techniques to predict LHV. These data-driven utilize 151 globally distributed datasets identified during systematic litera...
