Case: D-REX TLM in use on gasification system

Used equipment:

The challenge:

It’s common knowledge, that a lot of research is being done these years regarding alternatives to fossil fuels. One of these alternatives is gasification plants, which DTU has experimented with for a number of years.

A gasification plant is, in short, a way to convert biomass into tar-free combustible gas. Eg. By connecting a gas engine to the plant, in combination with an electricity generator, a small CHP plant with a low environmental load can be created.

The plant works by supplying biomass to a pyrolysis reactor, which is then heated without oxygen, which results in conversion to tar-containing gas and coke. The coke is led to the gasification reactor, where it is converted to gas, by limited addition of air. The tar-containing gas is passed to an oxygen chamber, where most of the tar substances are broken down, by the addition of oxygen. The gas and the remaining tar residues are then passed to the gasification reactor, where the tar content is further reduced, by mixing gas and the coke fraction. The remaining tar disappears when the gas is led up through the air.

The solution:

This is where Danova enters the picture, as we have delivered our standpipe solution D-REX TLM for the test.

It is essential that the level in the gasification chamber is closely monitored, as it must be possible to control it very precisely. It can only be done with radar. However, no measuring equipment can withstand the approx. 500-600 degrees heat it is exposed to. However, by mounting the radar on the self-cooling D-REX TLM, the temperature is lowered all the way down to about 40 degrees at the location of the radar, which ensures a continuous trouble-free measurement of the level.

We are happy to be able to help on a successful project, and not least, to be able to make our contribution to the green transition.
