Abstract

The invention discloses a rotational-flow-adjustable gas burner. The rotational-flow-adjustable gas burner comprises a primary air adjustment device, a secondary air adjustment device and an adjustable flame-stabilizing device, wherein the adjustable flame-stabilizing device comprises a bluff body head and an adjustment ring; the bluff body head comprises a bottom-free cylindrical outer shell, a frame fixed inside the outer shell, and a plurality movable wing plates, the center of the frame coincides with the axial center of the outer shell, the center of the frame is provided with a gas passage, the movable wing plates are connected to one plane between the gas passage and the outer shell through a rotation shaft, the movable wing plates can rotate with the rotation shaft being the center axis, the rotation shaft penetrates through the end of the outer shell and is connected with the adjustment ring through a hinge, the adjustment ring is connected with a pull rod, and the pull rid drives the adjustment ring to move up and down. The rotational-flow-adjustable gas burner can guarantee primary mixing of combustible gas and combustion-supporting gas through the primary air adjustment device, and can guarantee sufficient mixing of the mixed gas and secondary air through adjustment of a rotation angle of the movable wing plates, thereby guaranteeing stable combustion to the maximum extent.

Description

Technical field

[0001] The invention relates to a burner, in particular to an adjustable swirl gas burner used in the baking process of a refractory brick type gasifier. Background technique

[0002] The gasification technology represented by Texaco has been widely used in China. The gasification furnace type of this gasification technology can be called a hot fireplace, that is, the refractory bricks in the furnace must be preheated to above 1000 ℃, and then refractory Brick heat storage guarantees subsequent ignition and commissioning.

[0003] However, in the actual operation process, due to the characteristics of the entire process flow, in order to ensure the smooth progress of the oven process, not only the liquid level of the gasifier needs to be lowered below the downcomer, but also the vacuum degree and gas volume of the gasifier must be matched at all times. Lowering the liquid level can avoid the gasifier "gasp" phenomenon caused by pumping, but the temperature of the c...

Embodiment Construction

[0034] Such as Figure 1-2 As shown, an adjustable swirling gas burner includes a primary air regulator, a secondary air regulator, and an adjustable flame stabilization device. The primary air regulator is used to adjust the primary air when combustible gas is mixed with auxiliary gas. Inhalation, the primary air regulating device is installed on the top of the burner, the secondary air regulating device is used to adjust the secondary air suction when the combustible gas is mixed with the auxiliary gas, and the secondary air regulating device is installed at the bottom of the primary air regulating device. The adjustable flame stabilizing device is installed at the bottom of the secondary air regulating device through a tie rod 7; the adjustable flame stabilizing device includes a bluff head 10 and an adjusting ring 8; the bluff head 10 includes a bottomless cylindrical shell and is fixed to the shell The inner frame and several moving wing plates. The center of the frame coi...
