New agricultural biogas plant
Based on colleagues’ great experiences and recommendations, farmer Thomas Kjær chose to contact Danish Biogas Consulting regarding the implementation of a new agricultural biogas plant. The plant will deliver biogas for a new upgrading plant which transfers the gas to the nearby natural gas grid.
Danish Biogas Consulting’s Project Managers goal-oriented work in the preliminary screening phase led to the location of the right solution that was subsequently worked on.
The gas transfers through a gas pipeline about 1 km from the biogas plant to the receiving station. The production of gas is mainly based on biomass from own production. This means slurry from a pig herd as well as straw, grass and corn from own agricultural areas. The plant is based on a technology which can manage biomasses, like straw. Firstly, by an effective shredding of the biomasses when added to the plant, secondly by a large reactor capacity, so that the retention time of the biomasses in the plant is longer, and thirdly by an efficient control system, which ensures a uniform temperature and optimal economy.
The plant consists of a feeding system, a primary reactor with a volume of 4600 m3 and a post-gasification tank with a volume of 4600 m3 and an integrated gas storage. All the way through, the streamlining of the energy consumption in the production is kept in mind. There have, among others, been installed a heat pump system, which recover the waste heat to heat tanks and biomasses, just like there is recovery of waste heat from the upgrade plant of approximately 80 kW.
”I am very satisfied with the course of events, and I will use Danish Biogas Consulting again, just like I at any time would recommend them to my colleagues in the industry”.
”I have great respect for the broad experience and knowledge within agriculture and biogas that Danish Biogas Consulting has – they are fully aware of all the possible subsidy opportunities.”
KUHR HEDEGAARD I/S
Dairy receives biogas from agricultural biogas plant
I/S Kuhr Hedegaard, with farmer Michael Kuhr, Heine Kuhr and Henry Kuhr, have implemented a new agricultural biogas plant which delivers biogas to a nearby dairy, where the gas is used for electricity and heat production.
When it was clear that the project ”Biocenter Gudenå” ¬– the implementation of a local biogas plant in the outskirts of Bjerringbro – would not be completed, Lars Waage from Danish Energy Consulting and Danish Biogas Consulting contacted Michael Kuhr to offer consulting of an alternative solution.
Danish Biogas Consulting’s preliminary measurements and assessments brought numbers and facts on the table. “It was nice to have competent help in this phase, since the large amount of data easily seemed confusing”, says Michael Kuhr. ”Working with biogas is not something new to us, and our own knowledge and experience paired with Danish Biogas Consulting’s expertise, worked really well. We were well guided through the process, and Danish Biogas Consulting has been quick and effective with following up on our wishes and questions, both about solutions and subsidy potentials”.
The gas transfers through a gas pipeline approximately 4 km from the biogas plant to the nearby dairy where the gas is used for electricity and heat production. The production of gas is mainly based on biomasses from own production.
The agricultural biogas plant is fundamentally composed of a feeding system, a primary reactor with a volume of 4000 m3, and a post-gasification tank with a volume of 4600 m3, and an integrated gas storage. From start to finish, there have been thought of energy wise streamlining of production. Among others, a heat pump system is installed which recover the waste heat to heat tanks and biomasses.
Danish Biogas Consulting has followed the project to the end, where a biologist continuously analyse the processes in the plant. “We could not have been without Danish Biogas Consulting’s advice in this process,” stresses Michael Kuhr.
”We were well guided through the process. Unlike several other consultants we have had contact with, Danish Biogas Consulting is really well geared to handle the private agricultural sector,” says Farmer Michael Kuhr.
