Title: Multi-fuel heating equipment - has inert material forming bed fluidised by fuel-air mixture in widening reactor
Inventor: MICHEL WOLFGANG PROF
IPC: F23C10/00
Filed: 1990-04-11
Abstract: The equipment generates heat, using solid, liquid and/or gaseous fuel. It comprises a reactor (1) with tapering body widening towards the top at between 7 and 30 deg. and lined with fire brick. This is filled to a set height with inert material (5) forming a fluidised bed. Above this is a free space followed by a heat-transfer system (6) utilising the convective heat. Fuel and air feed systems give complete combustion with fluctuating fuel quality and smooth changeover between fuels. The inflow speed of the mixture of air and fuel is high enough to generate an internally-circulating fluidised bed, into which extra fuel and/or waste products are introduced from any direction, also necessary additives to prevent pollutant emission and air as necessary. This gives complete combustion in the free space. When bed temperature and that of the inert material has reached between 750 and 950 deg., this ignites all combustible material, heat-generation being regulated by the fuel supply. ADVANTAGE - Simplicity and high output.

Patent DE-4103844-A1 (DE)
Inventor: MUELLER BERND
IPC: F04D29/70
Filed: 1991-02-08
Abstract: The invention relates to a centrifugal pump, in which the impeller (10) is preceded by a filter pot (2) having a filter cartridge (6) arranged in it. The pump-part suction port (9) located in the filter pot (2) is preceded, as a result of the constructive design of the filter cartridge (6), by a free space (11), within which escaping filtrate collects.

Filed: 1992-03-03
Abstract: In a safety device against the failure of a nuclear reactor pressure vessel due to overpressure in case of insufficient cooling of the core, a temperature-dependent pressure discharge is provided. A pressure reliefs valve (4) which normally blocks by means of a closure piece (8) the flow between the inside of the pressure vessel (11) and a pressure discharge duct (10), is pressure-tightly set in a wall (1) of the pressure vessel (11).
