Integrated Biomass Energy System (IBES) - Biomass boiler, steam engine and generator integrated into a single unit - Measures 1.5m*1.5m*1.7m (W*D*H) and weights only 400kg - Simple, reliable and compact - Fueled from renewable sources - Producing 10.6kW of electrical power - Additional 25kW of heat (hot water) - Burns virtually any type of biomass - Automatic fuel feed - 1kg of biomass = 1kWh of energy (rule of thumb)
Typical use of IBES Steam Engine Generator and Biomass Silo Furnace: Steam and feed and Hot Water Power Regulator #1 Generation of 10kW can support up to 40 households with a continuous #2 consumption of 250W. This is enough to power 7*7W LED lights, a Power smartphone charger, a radio, a ceiling #3 distribution #40 #n fan and a fridge or TV
Hot water outlet IBES Tech Specs Additional energy, in the form of hot water, is available to power f.ex. a household radiator, absorption chiller, desalination unit etc. Oxygen Trim The Cyclone Engine is a Rankine Cycle Based on O2 readings the microcomputer heat regenerative external combustion increases or decreases the amount of fuel engine, otherwise known as a “ Schoell fed to the burner at the current output Cycle” (from Cyclone’s founder Harry level. Schoell) engine. It creates mechanical energy by heating and cooling water in a closed-loop, piston-based engine system. Mic icrocomputer con ontrol The microcomputer continuously monitors the heat demand and adjusts the output Generator of the furnace accordingly, taking into The generator is of a vary compact design, consideration a wide set of parameters to also referred to as a “pancake” generator. It maintain efficient and safe operations at output 10.6kW by means of 120/240/380V all times.

Fuel Feed System The microcomputer controlled and auger based fuel feed system Ash System / Biochar is designed to handle rough wood chips up to four inches long. The furnace is equipped with an automatic ash The fuel feed system also is part of the safety system as the extraction system conveying ashes from the auger creates a physical separation between the combustion combustion process out of the furnace into an side and the storage side. external container.

Cyclone steam engine Heat exchanger (Transfer energy from boiler to engine) - Developed by Cyclone Power technologies in the USA - Very compact design: 80cm diameter, weights 100kg - Electrical output of 10,6kW - Closed loop system. No need to refill water - All moving parts lubricated by water; no need for oil - Very silent, equivalent to the cooling fan on a car Steam engine
Generator • Very compact design. Also referred to as “Pancake” generator • Measures 50cm*50cm*50cm and weights under 50kg • 120/240V 1 Phase; 380V 3 Phase output
Why biomass? – Burning biomass , such as crop waste and wood pellets emits the same amount of CO2 as is absorbed while the plants were growing. Therefore, biomass is classed as carbon - neutral renewable energy. – Household waste consist of over 60% organic, combustible mass – Biomass has the potential to meet all power needs globally – Use garbage to generate electricity instead of depositing in landfills. – Can create jobs and activities
