Abstract
The present disclosure provides a method and apparatus for use in a flue-cured barn. The apparatus comprises a combustion chamber for burning fuel; an exhaust pipe for allowing combustion gases to leave the combustion chamber; and a fan for drawing the combustion gases along the exhaust pipe away from the combustion chamber and for generating a negative pressure within the combustion chamber and exhaust pipe compared with the pressure outside the apparatus.

Apparatus for use in a flue-cured barn comprising:
- a combustion chamber for burning fuel;
- an exhaust pipe for allowing combustion gases to leave the combustion chamber;
- a fan for drawing the combustion gases along the exhaust pipe away from the combustion chamber and for generating a negative pressure within the combustion chamber and exhaust pipe compared with the pressure outside the apparatus;
- an air inlet valve for providing an air supply into the combustion chamber;
- and
- a control system for controlling the combustion rate in the combustion chamber by adjusting (i) the fan for drawing the combustion gases along the exhaust pipe and (ii) the air supply through the air inlet valve.
A method of generating negative pressure in a flue-cured barn comprising:
- burning fuel in a combustion chamber;
- providing an exhaust pipe for allowing combustion gases to leave the combustion chamber;
- operating a fan to draw the combustion gases along the exhaust pipe away from the combustion chamber and to generate a negative pressure within the combustion chamber and exhaust pipe compared with the ambient pressure
- supplying air into the combustion chamber through an air inlet valve;
- and
- controlling the combustion rate in the combustion chamber by adjusting the fan and the air supply through the air inlet valve.
