ORC-biomass - ECOCAL®
ECOCAL® stands for "ecological caloric" and describes our organic rankine cycle product line for the electrification of biomass like wood chips, agricultural waste wood and such from the industry. It is the system based on the organic rankine cyle process for a combined heat and power production being capable to cover a range of heat and power devices from an electrical power output of 0.5 MWel on, more efficient and much more economic than the ordinary water steam process (CRC-process).
Comparison of ECOCAL®-organic rankine cycle -technology with the water steam power process
ECOCAL® offers significant advances compared to power plants operating based on the ordinary water steam cycle. for almost a hundred years it has been possible to produce heat and electricity by the combustion of piece wood with the help of steam engines. Such plants are mainly composed of:
- a firing for solid fuels,
- a steam boiler for the production of water steam,
- a machine such as a steam motor or a steam turbine coupled with a generator,
- and heat or air condensers.
Next to steam powered machines the boiler is the most expensive main component in the branch of steam power device production. Such systems for the production of high pressurized steam are very complex and sumptuous to produce. For the fabrication of steam boilers, steam pipes and steam boiler armatures, very durable, corrosion withstanding and ferritic-martensistic steel or high temperature withstanding austenitic power plant steel has to be used. Additionally, these special parts are only allowed to be mounted by qualified steam power plant assembling companies.
Contrary to the previous, for the production of electricity in ECOCAL®-power plants do not require a steam boiler. Furthermore in organic rankine cycle power plants the maximal pressures amount up to 10 bar. This means that for the production of ECOCAL®- modules ordinary low cost boiler steel can be used. Based on those pre named properties, ORC-power plants are much more cost effective to erect.
Also because of the low pressures in ECOCAL®-power plants they do not have to be supervised by specially trained personnel which leads to a much more economic working of those plants as well.
