Claim 11:
12. An evaporator system according to claim 1, wherein the stoppage sequence is triggered manually by pressing on a button of a control panel; wherein the stoppage sequence is automatically triggered by the controller when the evaporator system has not been fed with a new reload of biomass during a given period of inactivity; wherein the stoppage sequence includes a step wherein said at least one fan of the air supply system offering the at least one air supply to the combustion chamber, is operated at a preestablished value during at least one given range of time; wherein the fan of primary air, the fan of secondary air and the fan of intermediate air are operated at predetermined values when the stoppage sequences is initiated to ensure a complete combustion of the biomass present in the combustion chamber and a gradual cooling of the evaporator system; wherein after said given range of time, the controller measures the operating temperature in the combustion chamber to determine when the operating temperature is inferior to a given stoppage temperature, in which case, the controller continues to operate said at least one fan of the air supply system offering the at least one air supply to the combustion chamber, at said preestablished value of the stoppage sequence, during a cooling period; wherein after said cooling period, the controller measures the operating temperature inside the combustion chamber to determine when the operating temperature is inferior to a given stoppage temperature, the controller continues to operate said at least one fan of the air supply system offering the at least one air supply to the combustion chamber, at said preestablished value of the stoppage sequence, during another cooling period; or wherein after said another cooling period, the controller measures the operating temperature in a combustion chamber to determine when the operating temperature is inferior to a given stoppage temperature, in which case, said at least one fan of the air supply system offering the at least one air supply to the combustion chamber, is operated at zero.
