UTILIZATION OF WASTED HEAT
CLEAN ELECTRICITY GENERATION UNITS

HISTORY

Currently, there are many industrial processes in which wasted heat is generated that is not utilized and expelled directly into the atmosphere.
In order to comply with current environmental law, industries are being forced to reduce as much as possible their CO2 emissions; in addition, there is an emissions market in which this savings can mean economic, as well as environmental, benefits. If at the same time they reduce their emissions, industries can also generate electric energy, the economic benefits can be substantial.Nicolás Correa Service, S.A. aims to implement small-scale installations in the market that make it possible for industries to reduce their emissions and transform the residual energy of their processes, in an economic benefit that is both clean and environmentally friendly.
The main element of these installations will be the small-scale electric power generation unit (125 kW_e gross), which allows recovery of wasted heat, transforming it into electricity, allowing self-consumption from the first kilowatt generated with direct savings in the electric power bill, thus avoiding the costly procedures of grid connection, and all with zero additional emissions.

TECHNOLOGY
The clean electric power generation unit has a high-speed turbine, with a high-efficiency power module, in a single moving part, unsealed and without gearbox. It requires a heat source under certain conditions to generate useful power to supply an electric power grid thanks to sophisticated power electronics.The system allows operation at partial load so that it adapts to the residual heat conditions at all times. This residual heat can come from a wide range of systems (motors, industrial stacks, tips, etc.)

ADVANTAGES
- Clean energy with no needed fuel.
- Zero emissions and ecologically safe.
- Proven technology.
- High reliability, high profitability and low maintenance.
- High-speed and high-efficiency power module.
- Simple synchronization with utility.
- Small-footprint packaged unit: ready to integrate.
- Modular and scalable design, allowing the connection of several systems for different productions (125 kW_e, 250 kW_e, 375 kW_e …).
- Fast payback.

APPLICATIONS

The potential market for the clean electric power generation unit is wide and diverse, as it can be applied and installed in all industries with wasted heat from production or energy processes, including landfill gases or engine exhaust gases, biogas, biomass boilers, steam, industrial stacks, solar-thermal installations, etc.The great versatility of these units has caused NC Service to develop a new line of business centered on the searching for applications for the commercialization of this unit and its implementation in the market.Currently, the company advises industries on the application of this unit in their processes, subsequently taking responsibility for its design, sale, installation, assembly and maintenance.  

Example of application in a biomass plant
Located at the facilities that NC Service has in Burgos, is the first installation in Spain that utilizes this clean electric power generation unit to produce 125 kW_e, utilizing the heat from biomass combustion in a thermal oil boiler.  
The company organizes visits to see the operation of this unit and the biomass installation.
