Embodiment Construction

[0026] The present invention is a compact cogeneration plant that uses various fuels (gaseous or liquid hydrocarbons, biofuels, solid organics, etc.) as energy sources. The device is also capable of generating electricity using waste heat from another independent process as an energy source.

[0027] figure 1 A fuel burner 13, a high pressure turbine 01, a low pressure turbine 02 and a recuperator 07 for cooling fluid are shown.

[0028] The hydraulic pump 04 pumps the internal working fluid (such as water or some organic fluid) in a high-pressure fluid state to one side of the heat exchanger 05 . On the other side of the heat exchanger 05 the mixture of hot gases circulates burning some gaseous, liquid or solid fuel 12 in a burner 13 suitable for its type. figure 2 A variant of this solution is shown in which hot exhaust air from another machine or a separate treatment process 32 is suitably directed 33 to the heat exchanger 05 . In this scheme, the fuel is not burned by ...

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 obtainedby 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 magneticbearings 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.

Description

technical field [0001] The invention relates to the field of power generation and heating equipment. In particular, the invention relates to plants or small installations for combined heat and power. Background technique [0002] Distributed generation installations are low-power generation systems (below 1000 kilowatts) that can supplement part of the electricity consumption of user facilities (without affecting the grid) or inject power into the grid without requiring modifications to it. [0003] The combined heat and power system is an equipment or fixed facility that uses the waste heat of power generation equipment to fully or partially supply the heat demand of users. Conversely, there are combined heat and power systems that use the waste heat of a thermal process (furnace, boiler, etc.) to generate electricity. [0004] The invention is capable of functioning in either of two schemes, ie, self-heating or using external waste heat to generate heat. In both cases, ...
