Title:
GAS COMBUSTOR
Document Type and Number:
WIPO Patent Application WO/2019/029062
Kind Code:
A1
Abstract:
A gas combustor (10), comprising a main body (20), a flue gas channel (30), a first fuel injection device (50), and a sidewise fuel injection device (60). The main body (20) has a sidewall (21) extending along the axial direction, and the sidewall (21) is enclosed to form a cavity (22). The flue gas channel (30) is disposed at one end of the main body (20) and has a first inlet (31) and a first outlet (32). The first inlet (31) faces towards the side direction of the main body (20), the first outlet (32) faces towards the axial outer side of the main body (20), and the cross sectional area at the first inlet (31) of the flue gas channel (30) is greater than the cross sectional area at the first outlet (32). The first fuel injection device (50) is disposed in the cavity (22) and extends to pass through the flue gas channel (30). The first fuel injection device (50) comprises a first injector (51), and an injection end of the first injector (51) is located in the flue gas channel (30). The sidewise flue injection device (60) comprises a sidewise injector (61), and the sidewise injector (61) faces towards the side direction of the main body (20). The gas combustor (10) can effectively realize low-nitrogen combustion, and can sustain combustion within a wide load range.
