Low carbon self-sufficiency solutions

PRODUCE YOUR THERMAL ENERGY FROM WOODY RESIDUES AND RDF

Mini Green Power engineers, assembles and operates mini power plants that are local and clean, converting woody residues or Refuse Derived Fuels (RDF) to energy, including heat.

Technology

Staged combustion

The biomass is conveyed from the feed tank to the gasifier by conveyors. It is heated at high temperature in a low oxygen atmosphere to undergo three successive reactions: combustion, pyrogasification, and post-combustion. This process, patented by Mini Green Power, produces clean gas at more than 1.000 ° C.

The exhaust gas passes into a recovery boiler to heat a fluid used by the recovery process: superheated water, steam or thermal oil.

The generated heat can then be used for heating, drying or industrial processes using steam. The heat can also be converted into cold or electricity through specific modules.

Energie Thermique

Examples of thermal recovery

■  Hot or superheated water (90 to 110°C) for heating networks, heating or drying applications,
■  Overheated water (up to 180°C) for industrial processes,
■  Steam (saturated or superheated) up to 400°C and 40 bar for industrial processes,
■  Thermal oil up to 300°C for industrial applications,
■  Aquaponics, fish farming.

ELEMENTS THAT DIFFERENTIATE MGP PLANTS

1. A broad spectrum of accepted biomasses

Mini Green Plants accept a wide spectrum of plant residues, allowing our customers to stock up with a local and very economical resource, often less than 8 € / MWh.

BIOMASSES ACCEPTED :

■ Humidity level from 15% to 55%,
■ Ash rate up to 10%.

■ Examples of biomass accepted:
– Woody/wood part of green waste,
– Agricultural residues,
– Weakly treated wood waste.

2. Automation and big data solution

Our fully automated power plants backed by big data solutions enable minimized operating costs and continuous optimization.

■ Remote control tool developed internally,
■ Fully automated power stations for maximum autonomy,
■ Continuous optimization of installations thanks to data tracking,
■ Redundant security system.

3. Low emissions

The staged combustion system developed by Mini Green Power allows very low emission levels. The double filtration of the fumes makes it possible to reach very low dust levels:

■ Emissions of nitrogen oxides (NOx) very significantly lower than regulatory requirements (below 200 ppm even with low-quality biomasses),
■ Carbon monoxide (CO) emissions close to 0,
■ Dust levels below 20 ppm.
