摘要:
An arrangement for gasification of fuels within the range from fine grain fuel to dust shaped fuels, in a dust cloud with gas comprises a gasification reactor provided with at least two burners, a supply container for accommodating a fuel, a distributor connected to the supply container for receiving the fuel from the supply container, and a plurality of conduits connected with the distributor and supplying the fuel from the latter to the burners, the conduits having a different geometrical parameter including at least one of a length and a direction.
摘要:
A method of discharging residues resulting from gasification of fuel in a chamber filled in a lower portion thereof with water and having a gas cushion at high pressure above the water level, in which the residues accumulating in the chamber are discharged through a sluicing container connected to the lower end of the chamber and conveyor means connected to the sluicing chamber.
摘要:
The process for determining and controlling the fuel mass flow in partial oxidation and gasification of a fine-grained to powdery fuel includes particularly drawing the fuel from the supply vessel through a single outlet pipe and feeding the fuel to a distributor, in which a plurality of individual supply lines are connected to the individual burners, the fuel mass flow rate in the supply lines depending on the speed measured there and the radiometric density measurement being determined in the outlet pipe of the supply vessel. For control of the fuel mass flow a stepwise regulation depending on the crude gas flow produced in the gasification unit is thus provided.
摘要:
Charges of finely comminuted solid fuel particles are admitted into an oxygen-containing gasification chamber through a system of locks having an uppermost bunker which is maintained at atmospheric pressure, an intermediate bunker wherein the pressure alternately rises and drops, a lowermost bunker wherein the pressure is always above atmospheric, a metering device which connects the lowermost bunker with the gasification chamber, a pipe which can supply compressed inert gas into the intermediate bunker after the latter has received a charge of fuel particles from the uppermost bunker but before the intermediate bunker is respectively sealed from the uppermost bunker and connected with the lowermost bunker, and a pipe which evacuates compressed gas from the intermediate bunker subsequent to transfer of a charge into the lowermost bunker. The thus evacuated compressed gas is fed to a pneumatic conveyor which supplies charges of fuel particles from a main source to the uppermost bunker while the latter is sealed from the intermediate bunker. The gas evacuating pipe can contain a storage tank for compressed gas so that the admission of fuel particles into the uppermost bunker can be timed independently of the gas pressure in the intermediate bunker.
