Abstract

The utility model relates to a combustion device for fluid fuel, and the combustion device for fluid fuel is to realize a gas fuel stove which can make the gas fuel re-combust after being preheat and pressurized for the second time. The utility model comprises a combustion tube, a spray nozzle, a stove plate and an isolation tube, and also comprises a burning flame cover, a pressurization tube, a drain tube and a gas inlet device, and an inflow opening, a gas port and an overflow port are arranged on the stove plate. The designed stove structure is energy-saving; besides, the flame is also strongly compared with the stove which burns fuel directly.

Description

A kind of gaseous fuel kitchen range

The utility model relates to the burner of fluid fuel.

How the kitchen range of existing using gases fuel (combustion gas) can only allow fuel directly burn, and does not all have to allow the passage or a space of fuel preheating therein, repressurize.The heated body of these kitchen ranges is accepted is the direct combustion heat from its crater.

The purpose of this utility model is to realize a kind of gaseous fuel kitchen range of burning again that can allow behind fuel preheating therein, the secondary booster.

The utility model has combustion barrel, nozzle, stone or metal plate for standing a stove on as a precaution against fire and isolating cylinder, the upper end is positioned at the stone or metal plate for standing a stove on as a precaution against fire middle part for the combustion barrel of crater, nozzle is positioned under the combustion barrel, also have flame-cover, pressurization cylinder and drainage tube and air-intake device in addition, and influent stream mouth, gas outlet and overfall are arranged on the stone or metal plate for standing a stove on as a precaution against fire, wherein: a) top cover of flame-cover is positioned on the crater of combustion barrel, the flame-cover sidewall that is furnished with flame-hole is trapped among outside the combustion barrel, said isolating cylinder is trapped among outside the flame-cover sidewall, and the pressurization cylinder of barrel hollow is trapped among outside the isolating cylinder; B) drainage tube comprises influent stream pipe, air jet pipe and overflow pipe, and the influent stream pipe is communicated with the hollow space of pressurization cylinder barrel respectively through the gas outlet on the stone or metal plate for standing a stove on as a precaution against fire, the overflow pipe overfall on stone or metal plate for standing a stove on as a precaution against fire through the influent stream mouth on the stone or metal plate for standing a stove on as a precaution against fire, air jet pipe; C) air-intake device has the flame tube of leading that is communicated with combustion barrel, and the puff prot of air jet pipe is communicated with nozzle through leading flame tube.

The barrel of said pressurization cylinder is the sandwich that binds.

The gaseous fuel kitchen range of the utility model design has increased flame-cover, pressurization cylinder and drainage tube thereof etc., makes gaseous fuel get elder generation by the hollow part of influent stream pipe through influent stream mouth importing pressurization cylinder, and the air jet pipe through being communicated with it is directed to nozzle again; Under the ignition combustion tube from the gaseous fuel of nozzle, during combustion flame " effusion " crater that in combustion barrel, burns, can " be pressed to " the flame-cover sidewall by the flame-cover top cover, the combustion flame " is forced to " from the flame-hole of cloth on the flame-cover sidewall horizontal " effusion ", through isolating cylinder to its heat of pressurization cylinder (wall) radiation, after the pressurization cylinder barrel hollow of promptly the flowing through continuous heating of fluid fuel quilt and secondary booster partly, just through also being that the air jet pipe that is communicated with pressurization cylinder barrel hollow space is directed to nozzle (burned), thereby spray from nozzle, fuel in the combustion barrel internal combustion has passed through heating and repressurize.Designed kitchen range structure is except that energy-conservation, and also directly the burner intensity of a fire of combustion fuel is more prosperous for its flame, and the combustion heat utilization of fuel is abundant.

The utility model is described in further detail below in conjunction with accompanying drawing.
