Objective
Aim of the project is to built a straw gasification plant at the Hojreby district heating for the production of electricity and thermal power. Straw is first reduced in size in a a bale cutter and via a cyclone and vibrator is supplied to 3 buffer storage silos. The plant consists of 3 identical gasifiers. Produced gas is cooled, filtered and fed to a gas storage unit. The process uses a catalyst and steam as gasifying medium producing a medium calorific value gas. The generator set has an electric output of 480 kW and a thermal output of 730 kW. Innovative aspects are not explicit but should be related to the combination of catalyst and steam gasification.
The project comprises the design, the construction and the starting-up and commissioning of a catalytic biomass gasification plant.
The actual biomass to be gasified is straw, but the gasification process is capable of handling other types of biomass i.e. rice husks, woodchips, bagasse a.o.
The main components of the plant are :
- The straw feeding system
- The straw gasification unit w. auxiliary equipment
- The biogas storage
- The biogas driven engine/generator unit w. heat exchanger.
The biogas will be used as fuel for a gas engine with a combined production of electric power to the public network and hot water to be supplied to the adjacent district heating plant.
The objective of the project is on a full scale basis to demonstrate the viability of the gasification process developed by Dansk Termo Industry AS.
The process is employing a technique of indirect heating of the biomass giving a biogas well suited for gas driven engines without extensive gas cleaning.
