Abstract
A down-draft gasification reactor has a solids storage chamber bordered from below by a grate and having an oxidation zone, a product gas collection region disposed beneath the grate, a product gas line for discharging out-gassed product gas from the product gas collection region, a slag-separation device disposed above the grate, and a discharge mechanism downstream of the grate for transporting the separated slag out of the reactor.
Claims63
A down-draft gasification reactor (1) for the gasification of organic solids having high ash content and tending to form slag,
- with a solids storage chamber (4) for accepting solids and bordered from below by a grate (18), wherein the solids storage chamber (4) has an oxidation zone (12) having an intake for at least one of air and oxygen,
- with a product gas collection region (20) disposed beneath the grate (18),
- with a product gas line (22) for discharging the out-gassed product gas and ending in the product gas collection region (20), and
- with a slag-separation device disposed above the grate (18) and a discharge mechanism for transporting the separated slag out of the gasification reactor.
A method for gasification of biological organic fuels, including residual or waste products such as sewage sludge (4), wood, liquid manure, characterized in that the fuel is gasified in a down-draft gasification reactor having a solids storage chamber (4) for accepting solids and bordered from below by a grate (18), wherein the solids storage chamber (4) has an oxidation zone (12) having an intake for at least one of air and oxygen, with a product gas collection region (20) disposed beneath the grate (18), with a product gas line (22) for discharging the out-gassed product gas and ending in the product gas collection region (20), and with a slag-separation device disposed above the grate (18) and a discharge mechanism for transporting the separated slag out of the gasification reactor.
An installation for disposal of sewage sludge (40), characterized in that the installation has a down-draft gasification reactor having a solids storage chamber (4) for accepting solids and bordered from below by a grate (18), wherein the solids storage chamber (4) has an oxidation zone (12) having an intake for at least one of air and oxygen, with a product gas collection region (20) disposed beneath the grate (18), with a product gas line (22) for discharging the out-gassed product gas and ending in the product gas collection region (20), and with a slag-separation device disposed above the grate (18) and a discharge mechanism for transporting the separated slag out of the gasification reactor, wherein the reactor is operated to gasify biological organic fuels.
An installation for the production of gas-fuel, characterized in that the installation has a down-draft gasification reactor having a solids storage chamber (4) for accepting solids and bordered from below by a grate (18), wherein the solids storage chamber (4) has an oxidation zone (12) having an intake for one of air and oxygen, with a product gas collection region (20) disposed beneath the grate (18), with a product gas line (22) for discharging the out-gassed product gas and ending in the product gas collection region (20), and with a slag-separation device disposed above the grate (18) and a discharge mechanism for transporting the separated slag out of the gasification reactor, wherein the reactor is operated to gasify biological organic fuels.
A block heating and power station (56) for the production of electrical energy (47) and of thermal energy (48) though the combustion of a fuel in an internal combustion engine (46), characterized in that the block heating and power station (56) has a down-draft gasification reactor having a solids storage chamber (4) for accepting solids and bordered from below by a grate (18), wherein the solids storage chamber (4) has an oxidation zone (12) having an intake for at least one of air and oxygen, with a product gas collection region (20) disposed beneath the grate (18), with a product gas line (22) for discharging the out-gassed product gas and ending in the product gas collection region (20), and with a slag-separation device disposed above the grate (18) and a discharge mechanism for transporting the separated slag out of the gasification reactor, the product gas (23) of which is used as fuel for the internal combustion engine (46).
