Abstract

A gas compression compact device comprised of: a) one or more centrifugal compressors; and b) a high speed axial flow permanent magnet synchronous electric motor. The electric motor and the compressor are directly coupled on a single axis and supported by passive magnetic and electrodynamic bearings, free of lubrication. The equipment does not use mechanic seals since the rotor is placed inside the pressure containment of the gas. The equipment does not require auxiliary systems for cooling, filtration, separation or feeding of lubricant fluids.

IPC Classes  ?

• F04D 17/00 - Radial-flow pumps specially adapted for elastic fluids, e.g. centrifugal pumps; Helico-centrifugal pumps specially adapted for elastic fluids
• F04D 1/00 - Radial-flow pumps, e.g. centrifugal pumps; Helico-centrifugal pumps
• F04D 29/04 - Shafts or bearings, or assemblies thereof
• F04D 29/058 - Bearings electromagnetic
• F25B 1/04 - Compression machines, plants or systems with non-reversible cycle with compressor of rotary type

Abstract

A compact heat and electricity co-generation device comprised by: a) a heat generating system connected to a steam generator, a condenser and an internal working fluid, wherein said steam is obtained by external combustion of a suitable fuel in a boiler and/or by conduction of external hot gases to a boiler; y b) an electricity generator system comprised by: i) one or more radial and/or axial turbines; ii) an electric axial flow generator; and iii) an electronic control inverter. The fuel can be a solid, liquid or gaseous fuel. Both the turbine and the electric generator have passive magnetic bearings and electrodynamic bearings. The equipment does not use mechanical seals as all moving parts are housed within working fluid the pressure containment of the working fluid.

IPC Classes  ?

• F01D 15/10 - Adaptations for driving, or combinations with, electric generators
• F01K 23/06 - Plants characterised by more than one engine delivering power external to the plant, the engines being driven by different fluids the engine cycles being thermally coupled combustion heat from one cycle heating the fluid in another cycle
• H02K 7/18 - Structural association of electric generators with mechanical driving motors, e.g.with turbines
