Abstract
A gasifier includes a combustion zone where a gas is introduced and fuel is combusted and at least one sensor for measuring a predetermined condition in the gasifier. A grate subsystem contains the fuel and includes at least one grinding mechanism. A controller is responsive to the at least one sensor and controls the grinding mechanism by activating the grinding mechanism if the predetermined condition exists to reduce the collection of non-fuel products on the grate subsystem.
Claims39
A gasifier comprising:
- a combustion zone where a gas is introduced and fuel is combusted;
- at least one sensor for measuring a predetermined condition in the gasifier;
- a grate subsystem for containing the fuel, the grate subsystem
- including at least one grinding mechanism between downwardly angled grates defining a hopper;
- and
- a controller, responsive to the at least one sensor, for controlling
- the grinding mechanism, the controller configured to:
- control the grinding mechanism if the predetermined
- condition exists to reduce the collection of non-fuel products on the grate subsystem.
A gasifier grate subsystem comprising:
- at least two downwardly angled fixed grates defining a hopper area
- between the grates;
- at least two spaced grinding shafts disposed in the hopper area;
- and
- a controller, responsive to a sensor, configured to control
- the grinding shafts if a predetermined condition exists to reduce the collection of non-fuel products on the fixed grates.
A gasifier grate control system comprising:
- a grate subsystem for containing fuel in a gasifier, the grate
- subsystem including at least one grinding mechanism between downwardly angled grates defining a hopper area;
- and
- a controller, responsive to at least one sensor, for controlling the
- grinding mechanism, the controller configured to actuate the grinding mechanism if a predetermined condition exists to reduce the collection of non-fuel products on the grate subsystem.
A gasifier comprising:
- combusted;
- a combustion zone where a gas is introduced and fuel is
- a grate subsystem for containing the fuel
- including downwardly angled grates defining a hopper area and including at least one grinding shaft proximate the hopper area;
- and
- a controller configured to control the grinding shaft.
A gasifier grate control system comprising:
- a grate subsystem for containing fuel in a gasifier, the grate
- subsystem including downwardly angled grates defining a hopper area and at least one grinding mechanism proximate the hopper area;
- and
- a controller for controlling the grinding mechanism.
A gasifier grate control system comprising:
- a grate subsystem for containing fuel in a gasifier, the grate
- subsystem including downwardly angled grates defining a hopper and at least two grinding shafts disposed below the hopper;
- and
- a controller for controlling the grinding shafts.
