<p>PURPOSE:To nullify the electric power cost and at the same time eliminate the limitation as for the installation location by a structure wherein not an electric motor but a non-electric power source driven type stirling engine to rotate itself by employing the heat generated by a heater as energy source is employed as the driving source of a blast fan. CONSTITUTION:When a combustion burner 8 is ignited, flame heats the heating part 2 of a Stirling engine 1. By the way, the Stirling engine 1 does not start by itself. When the temperature of an engaging plate 12, which is contactingly fixed to the heating part 2, reaches the predetermined temperature, the engaging plate 12 made of shape memory alloy deforms itself to the figure as indicated with th broken lines, resulting in disengaging the engaging state of the plate 12 with the hook part 9a of a starting plate 9 and consequently allowing the starting plate 9 to be pulled by a spring 11 and a plate member 10 to rub the flywheel 3 of the Stirling engine 1 in order to turn the engine in the direction as indicated with the arrow P in order to start. The flywheel 3 keeps on turning as long as the heating part 2 of the Stirling engine 1 is heated when the turning force is once applied to the flywheel 3, resulting in turning a blast fan 7 through a belt 5.</p> |
