Abstract
Disclosed is a control system for controlling the feed of a solid fuel in a combustion process. The system includes a control unit which is adapted to communicate by way of a communications link in the system, to receive from online measuring instruments online measurement data regarding a fuel coming from a fuel reception unit, and to control a feeding unit for delivering the measured fuel into a fuel silo on the basis of its content model and measurement data.

A control system for controlling a feed of a solid biofuel in a combustion process, said control system comprising:
- a control unit;
- a fuel reception unit;
- a fuel silo for fuel storage;
- silo feeding means;
- silo discharging means;
- and
- online measuring instruments installed between the fuel reception unit and the fuel silo,
- wherein the control unit is configured
- to communicate by way of a communications link in the system,
- to receive, from the online measuring instruments, online measurement data regarding fuel coming from the fuel reception unit,
- to calculate, continuously from the received measurement data, at least one criterion of the fuel, and
- to establish a content model of a fuel distribution in the fuel silo based on the at least one criterion,
- wherein said content model of the fuel distribution establishes, in at least two dimensions, how the fuel is distributed in the fuel silo, and
- wherein the control unit is configured to inform
- the silo feeding means, based on said content model of the fuel distribution and the received measurement data, regarding to which part of the fuel silo the measured fuel is delivered, and
- the silo discharging means, based on said content model of the fuel distribution, regarding from which part of the fuel silo stored fuel is discharged.
A control unit for controlling a feed of a solid biofuel in a combustion process, comprising:
- a data transfer unit that receives by way of a communications link, from online measuring instruments installed between a fuel reception unit and a fuel silo for fuel storage, online measurement data regarding fuel coming from the fuel reception unit;
- and
- a processor unit configured to continuously calculate, from the measurement data, at least one criterion of the fuel,
- the processor unit further configured to establish a two-dimensional content model that establishes, in at least two dimensions, how the fuel is distributed in the fuel silo based on the at least one criterion,
- the data transfer unit configured to inform, based on said content model and the received online measurement data, and by way of the communications link, a silo feeding means regarding to which part of the fuel silo the measured fuel is delivered, and
- the data transfer unit further configured to inform, based on said content model and by way of the communications link, a silo discharging means regarding from which part of the fuel silo stored fuel is discharged.
A control method for controlling a feed of a solid biofuel in a combustion process, comprising:
- receiving, from online measuring instruments installed between a fuel reception unit and a fuel silo for fuel storage, via a data transfer unit of a control unit and by way of a communications link, online measurement data regarding fuel coming from the fuel reception unit;
- continuously calculating from the measurement data, by way of a processor unit of the control unit, at least one criterion of the fuel;
- establishing, via the processor unit, a two-dimensional content model that establishes, in at least two dimensions, how the fuel is distributed in the fuel silo based on the at least one criterion;
- informing, based on said content model and the received online measurement data, via the data transfer unit and by way of the communications link, a silo feeding means regarding to which part of the fuel silo the measured fuel is delivered;
- and
- informing, based on said content model, and via the data transfer unit and by way of the communications link, a silo discharging means regarding from which part of the fuel silo stored fuel is discharged.
A computer program for controlling a feed of a solid biofuel in a combustion process, said computer program recorded on a non-transitory computer-readable recording medium, said computer program, upon execution by the computer, causing the computer to:
- receive, by way of a communications link, from online measuring instruments installed between a fuel reception unit and a fuel silo for fuel storage, online measurement data regarding fuel coming from the fuel reception unit;
- continuously calculate, from the measurement data, at least one criterion of the fuel;
- establish a two-dimensional content model that establishes, in at least two dimensions, how the fuel is distributed in the fuel silo based on the at least one criterion;
- inform, based on said content model and the received online measurement data, and by way of the communications link, a silo feeding means regarding to which part of the fuel silo the measured fuel is delivered;
- and
- inform, based on said content model and by way of the communications link, a silo discharging means regarding from which part of the fuel silo stored fuel is discharged.
