Patent FR-2515786-A1 (FR)
Inventor: NARAY FERENC
IPC: F23H11/10
Filed: 1982-07-20
Abstract: The invention relates to grate elements and a supporting grate assembled from these for the combustion of coal or other solid fuels such as agricultural or industrial wastes, with which grate elements only the smaller portion of the required air cross-section is fixedly formed in the grate elements, while the larger portion is adjustable, corresponding to the fuel, by the flap-like opening and closing of the rows of grate elements. The rows of grate elements are supported by tiltable beams which are connected together by adjustment rods, so that grate tongues are formed. The regulation of the air supply of the grate is effected by the flap-like opening, i.e., the variation of the air resistance of the grate elements, and this can be carried out for each zone separately or over the whole supporting grate area, and also during operation.

Title: Installation for the generation of energy from the heat given off by a hot source.
Inventor: KRIEGER FRANCOIS
IPC: F02G5/02
Filed: 1982-08-13
Abstract: The invention relates to an installation for the generation of energy from a hot source by means of a working fluid which circulates in closed circuit and which is heated, evaporated, then expanded in an engine member, condensed and once again heated and evaporated. The steam produced in a heat exchanger 10 is superheated in order to feed a turbine engine 14 where it is expanded, then arrives at a condenser 18 and is restored to pressure by a circulation pump 26. The turbine engine 14 supplies a power of between approximately 8 and 18 % of the nominal power of a Diesel engine when the heat exchanger 10 is fed with the exhaust gases of this engine. The invention is used particularly for recovering thermal energy dissipated by an internal-combustion engine.
