MODULAR BURNER DEVICE Russian patent published in 2000 - IPC

FIELD: heat engineering, applicable in the systems of heating boilers (low and medium capacities) and in other fuel-combusting installations operating on liquid or gaseous fuel, as well as a self-contained portable burner. SUBSTANCE: the device has a fan scroll casing provided with an engine and connected to the base, having pipe connections with detachable plugs. The base is made for installation of replaceable pipes or detachable replaceable units for controlled feed of liquid or gaseous fuel respectively. The unit for controlled feed of liquid fuel has a fuel-distribution means (mounted on the detachable body) in the form of an injector with electrodes for ignition of fuel, fuel line connected to the fuel pump installed on the engine shaft through a detachable adapter (dismountable). The unit for controlled feed of gaseous fuel has a gas nozzle (mounted on the detachable body) with electrodes for ignition of fuel, pipe- line connected to the gas feed control unit provided with an air pressure transducer. The use of the detachable adapter and plugs for pipe connections in the fan scroll casing provides for multiple reinstallation of replaceable controlled fuel feed units upon user's selection, which makes it possible to use fuel depending on its cost and/or availability on sale. EFFECT: enhanced reliability due to reduced dynamic loads at starting. 7 cl, 8 dwg
