One of the new energy sources under experimentation is the municipal solid wastes, from which it is possible to recover a refuse derived fuel (r.d.f.) suitable to be burnt in electric power facilities, cement kilns and other thermal plants. The ''Istituto di Fisica Tecnica'' of ''Politecnico di Milano'' has set up a pilot plant for the testing of a combustion facility which can use the first of these fuels produced in Italy, and some other ones. The plant consists of a marine boiler, a conventional burner suitably modified, a pneumatic transport system for the r.d.f., a primary air fan, and a gas oil pump. It is connected with the boiler testing station of the Institute, which operates according to the enthalpy balance method. The characteristics and the aim of this research are to demonstrate that it is possible to utilize a r.d.f. in a nearly conventional small burner. The power of our plant is 250 kW (870.000 BTU/h), of which, at most, 75% can consist of r.d.f. The combustion tests have been carried out with different refuse derived fuel/gas oil ratios, and air/fuels ratios. The thermal balances show an efficiency decrease by a r.d.f. increase: 88% for full gas oil against 80% at 28% r.d.f. An increase in the CO/sub 2/ percentage has also been observed in the flue gases, as r.d.f. increases at constant power input (from nearly 10% with full gas oil to 14% with 28% r.d.f.).
