Development of a combined heat and power plant in the lower wattage range with vegetable oil supply (ASTRA2006/004)
Overview
Background & policy context:
The end of 2008 saw the successful conclusion of the CTI-Project „Rapeseed Oil Block Heat and Power Plant“ (BHKW) carried out by the Agricultural Engineering department of the Swiss College of Agriculture (SHL) and its commercial and sponsorship partners. Two lasting values remain: a small oil mill for extracting high quality rapeseed oil fuel and a modern block heat and power plant run with the locally produced oil.
Objectives:
Main objectives of the project are as follows:
- To furnish the scientifically tested and optimised technology for the use of cold-pressed untreated vegetal oil in heat and power plants in the lower wattage range.
- Establish a heat and power plant with a capacity of 130 kWmech and 110 kWel and an efficiency coefficient of hel = 37 %, which runs trouble-free with untreated vegetal oil and meets the Swiss emission limits according to the Ordinance on Air Pollution Control OAPC
- Detailed emission measurements with special emphasis on particulate matter to allow the transfer of the experiences to mobile engines.
- Establish a decentralised oil pressing facility as a reference plant to guarantee the supply of sufficient rape-seed oil meeting the quality standards defined by the Weihenstephaner-Norm.
Methodology:
The project consists of the following workpackages:
Work Package 1: provision of motor and combined heat and power plant (CHP)
- Task 1a: Simulation to optimise the engine
- Task 1b: motor preparation and vegetable oil conversion
- Exercise 1c: bench tests
- Task 1d: Assembly and placement of CHP
Work Package 2: plant for oil extraction
- Task 2: Supply small oil mill
- Task 2b: Installation small oil mill
- Task 2c: Commissioning and oil supply in accordance with RK Quality Standard 05/2000
Work Package 3: build trouble-free continuous operation CHP
- Task 3a: Motor-related experiments with CHP
- Task 3b: Emissions-related experiments with CHP
Work package 4: Agronomic and ecological investigations on potential industrial rape
- Task 4a: literature search and inventory
- Task 4b: Evaluation of "energy oilseed rape”
Work Package 5: Project Management and Reporting
- Task 5: Project Management
- Task 5b: Reporting and Transfer
