Abstract
A method for ventilating an oven configured to cure a binder bonding mineral fibers placed on a conveyor, the oven including, in series on the path of the conveyor, an inlet, a plurality of heating chambers and an outlet, the method including a procedure in which a predictive model for estimating an amount of pollutants is used.
Claims13
A method for ventilating an oven configured to form a mat of mineral fibers by firing a binder bonding a mineral material placed on a conveyor, the oven comprising, in series on a path of the conveyor, an inlet, a plurality of heating chambers and an outlet, the ventilation method comprising at least the implementation, by a control unit of the oven, of a plurality of successive steps that comprise:
- a first step of determining by computing, chamber by chamber or set of chambers by set of chambers, an amount of pollutants present in at least two chambers or two sets of chambers of the oven, said first step implementing a comparison of features of a current operation of the oven with a predictive model defined upstream and implemented in the control unit of the oven,
- a second step of determining by computing a minimum ventilation flow rate for a discharge of the amount of pollutants in each of the two chambers or of the two sets of chambers, and
- a third step of generating an independent control instruction intended for each of the chambers, or of each of the sets of chambers, for specific ventilation of each chamber or of each set of chambers as a function of the minimum ventilation flow rate calculated previously specifically for each of the chambers or set of chambers.
An oven configured to form a mat of mineral fibers by firing a binder bonding a mineral material placed on a conveyor, the oven comprising, in series on the path of the conveyor, an inlet, a plurality of heating chambers and an outlet, the oven comprising at least one control unit configured to control operation of each of the chambers.
