Negative-pressure full-premixing type fuel gas heater

Disclosed is a negative-pressure full-premixing type fuel gas heater. A gas passage is formed in the axial directions of a motor, a mixer, a fan, a front connector, a rear connector and a burner nozzle of a combustor, so that gas flow can penetrate through the integral combustor, and the gas passage...

Beschreibung
Zusammenfassung:	Disclosed is a negative-pressure full-premixing type fuel gas heater. A gas passage is formed in the axial directions of a motor, a mixer, a fan, a front connector, a rear connector and a burner nozzle of a combustor, so that gas flow can penetrate through the integral combustor, and the gas passage is used for flowing of combustion gas. A sealed cavity consists of the front connector and the rear connector of the combustor, and the fan is driven to rotate in high speed by the motor inside the cavity so as to form a negative area inside the mixer. The combustor is supplied with gas in a negative mode, and a reducing valve can only be opened when the combustor is provided with sufficient negative pressure so that gas supplying is guaranteed. Gas inside the combustor is mixed according to the Venturi principle, dynamic and static air and fuel gas combustion ratio of the heater is guaranteed, mixing effect is better, and the fuel gas heater conforming to market trend more effectively saves energy and protects en
