Abstract (en)

[origin: EP0869318A1] For stoves burning e.g. liquid fuel on wicks, combustion is controlled by battery-powered (6) microprocessor unit (B), with associated thermostat (9) and manual switch (11), altering wick height through an actuator (10). A monitor (7) shuts the stove down on battery failure. Arrangements for other fuels are generally similar. In the gas level detector (C), a thermal sensor (4) responds to a thin-film resistance heater (3), indicating the thermal conductivity of the ambient gas. Levels measured by Wheatstone bridge (5) pass, amplified (2) to the controller (B), which shuts the stove down if a set carbon dioxide level is exceeded. A discriminator (D) especially prevents shut-downs due to other gases.
