This low-emission electricity generation unit is a key component of the Greenvironment cogeneration systems, with an electrical output of 200 kW and a thermal output of up to 345 kW. The primary energy source of the C200 microturbine is natural gas, while the CR200 turbine can also burn lower-energy fuels such as biogas, landfill or mine gas. Greenvironment GmbH offers the CR200 microturbine as part of the CR200 cogeneration plant for repowering existing biogas plants or for building new ones. The energy recovery and therefore the use of a heat exchanger depends on the thermal concept. For example, when drying fermentation residue, direct use can be made of the low-emission exhaust air. For local and district heating, the exhaust air of the microturbine is used to heat water.
We use microturbines manufactured Capstone Turbine Corporation Inc. Based in Chatsworth (USA), the company has offices in 30 countries around the world and is the global market leader in microturbines.
Capstone applications have currently accumulated more than 21 million service hours in more than 5000 plants around the world. The mean time before failure (MTBF) is 14,000 service hours (C65).
Capstone microturbines are renowned for their efficient and environmentally friendly operation. The generator, compressor and turbine are mounted on a shaft which rotates at 60,000 rpm on an air bearing. In practice, this means no lubricants, no cooling water and very little wear. The microturbines have a maintenance interval of 8,000 hours and a calculated service life of 80,000 hours. The time and expense needed for maintenance are much less than for a gas engine. The microturbines offer maximum reliability and are suitable for both indoor and outdoor installation.
As well as being very quiet (70 dBA at 10 metres), the microturbines have significantly lower pollutant emissions than gas engines. With continuous combustion at comparatively low temperatures, microturbines achieve excellent exhaust emission values without additional treatment.
The exhaust has a temperature of 280°C. In the exhaust flow of the microturbine there is a heat exchanger with a thermal output of at least 245 kW. This heat exchanger provides the cogenerated heat required locally. Because the microturbines do not require any cooling and the entire thermal output is in the exhaust, the heat extraction can be very flexibly designed. They can easily overcome significant differences between the supply and return temperatures, and cooling is possible with the aid of an absorption refrigeration unit.
A CR200 microturbine can provide enough electricity for 500 three-person households. It can also supply 70 three-person households with heating and hot water. This is equivalent to a total of 245,000 litres of heating oil each year which the CR200 microturbine replaces with environmentally friendly energy. These calculations are based on an average household electricity consumption of 3500 kWh (3.5 MWh) per year and a 250 kW heat exchanger.

June 7- 11, 2010 4th Capstone European C65 ASP Training, Schmalkalden
From 07.06. - 11.6.2010 Capstone will held the fourth Authorized Service Provider Training (ASP) in Schmalkalden, Germany.
Also this year the European ASP Capstone Training is organized by Greenvironment. Service technicians from all over Europe can register by the following e-mail address training@capstoneturbine.com.
After passing the exam on the last day of training, participants will receive their Capstone ASP certificate. Thus they are among the specially-trained technicians of the innovative and sustainable microturbine technology.
