Title:
MINIATURE PULSED HEAT SOURCE
Document Type and Number:
WIPO Patent Application WO2001084061
Kind Code:
A3
Abstract:
A miniature heat source (12) capable of being used in a hand-held device for delivering a metered pulse of fuel to a combustion chamber where it is converted into a pulsed amount of heat. For example, the heat source apparatus (12) can be used in a hand-held cigarette smoking system (120) or within a portable device wherein a microturbine (70) generates electricity, as well as any type of environment where a high energy pulse of heat is used. The heat source includes a valve (34) such as a sliding (32), rotatable or timed valve which delivers a metered volume of fuel to the combustion chamber. The valve can deliver the fuel, in an expanded gaseous form, to a venturi conduit (50) which increases the velocity of the gas flow, and delivers the fuel to a combustion camber (26) where the gas is mixed with air. The combustion mixture is then combusted within the consistent, controlled and pulsed amount of heat with a higher energy capacity as compared to battery powered heat sources.
