Abstract
In a process for thermal pest control, a fuel-operated heater with separate flue gas routing is used to heat up a space to be treated. Fumigants may be additionally introduced into the air of the space to be treated, especially if the combustion chamber 13 of the heater is separated from the heat exchanger chamber 8 of the heater in a gas-tight manner. The process is particularly suitable for disinfecting mills and food-processing plants.
Claims12
A process for disinfestation of a pest-infested enclosed space, the process comprising the steps of:
- providing a combustion heater generating exhaust flue gas;
- circulating air between the pest-infested enclosed space and the heater to heat the air in the enclosed space and increase a temperature of the enclosed space to above approximately 22 degrees Celsius while maintaining the air from the enclosed space separate from the exhaust flue gas;
- introducing sulfuryl fluoride into the enclosed space at one of before, during or after said heating of the air of the enclosed space.
A process for the disinfestation of a pest-infested enclosed space, the process comprising the steps of:
- introducing hot air into the space to be treated by means of a fuel-heated heater;
- providing the heater with a separate flue gas routing, as a result of which no flue gases will enter the space being treated;
- providing the heater with a combustion chamber;
- providing a heat exchanger and a heat exchanger chamber;
- separating the heat exchanger from a combustion chamber in a gas-tight manner;
- circulating air from the enclosed space being treated through the heat exchanger chamber and back to the enclosed space continuously or intermittently, and heating the air during said circulating to increase a temperature of the enclosed space to within a range of approximately 22-40 degrees Celsius;
- introducing sulfuryl fluoride as a fumigant into the space being treated before, during or after the heating of the air of the space being treated.
A process for the disinfestation of mills, food-processing plants or other pest-infested rooms, the process comprising the steps of:
- introducing hot air into a room to be treated by means of a fuel-heated heater;
- providing the heater with a separate flue gas routing, as a result of which no flue gases will enter the room being treated;
- providing the heater with a combustion chamber;
- providing a heat exchanger and a heat exchanger chamber;
- separating the heat exchanger from the combustion chamber in a gas-tight manner;
- removing air to be heated from the room being treated through the heat exchanger chamber continuously or intermittently and heating the air;
- returning the air into the room being treated;
- and
- introducing sulfuryl fluoride as a fumigant into the room being treated before, during or after the heating of the air of the room being treated, said heating of the air is performed to raise a temperature of the air in the room being treated to within a range of approximately 22-40 degrees Celsius.
