Problems solved by technology

The general industrial furnaces are only suitable for the traditional direct-flow diffusion burner. If the fully premixed metal fiber burner is used instead, the structure of the furnace must be modified to adapt to the combustion characteristics of the horizontal fire.
In addition, the flow resistance of the air-fuel mixture on the metal fiber is very high, and the pressure head of the fan is also high; the metal fiber mesh is woven with a heat-resistant metal wire with a diameter of about 20 μm, which is very easy to burn

Embodiment example

[0066] Head installation requirements: the head shell is designed to be bell-shaped, and the inside is a slit-shaped fire outlet formed by stacking metal rings with a thickness of 1mm. 1mm. The rings should be stacked neatly to avoid problems such as misalignment and uneven thickness. The front end of the annular cylinder is fixed to the fire outlet of the shell, and the rear is fixed to the designed bracket, which is embedded in the ring of the back cover of the shell. There should be a ceramic fiber board inside the bracket for heat insulation, so as to avoid the high temperature of the head burning and burn the back shell.

[0067] The head of the present invention is a side air intake, and the air-fuel mixture enters the burner head from the side of the shell, so the ignition pin and flame detector can be installed behind the burner head, and directly extend into the head to ignite. Avoid the problems of external collision and inconvenient transportation.

Abstract

The invention relates to a full-premixing combustor and a control system thereof. The full-premixing combustor comprises a mixer, a fuel gas electromagnetic valve, a controller, a fan, a burner head igniter and a flame detector, wherein the burner head igniter comprises a burning brick and a slotted cylinder, the burning brick is connected with the slotted cylinder, a fixing flange is installed between the burning brick and the slotted cylinder, the left side of the slotted cylinder is connected with ceramic fibers, and supports are arranged around the ceramic fibers; and the slotted cylinderand the ceramic fibers are sleeved with a shell, a rear cover is arranged on the top of the shell, a fan connector is arranged on the side face of the shell, the fan connector is connected with a fan,the fan is connected with a mixer, the fuel gas electromagnetic valve is arranged beside the mixer, and the controller is connected with the fuel gas electromagnetic valve. The full-premixing combustor has the beneficial effects that the problem of easy burning loss of metal fibers is avoided, extremely thin slits also play a role in tempering prevention, and the full-premixing combustor has thecharacteristics of high thermal efficiency, low NOX emission and the like.

Description

technical field [0001] The invention relates to the technical field of combustion, in particular to a fully premixed burner and a control system thereof. Background technique [0002] The characteristic of the traditional once-through diffusion burner is that the air and fuel enter the head through different pipes before combustion, without mixing in advance, and the air and gas are mixed and burned at the head. Due to uneven air-fuel mixture and incomplete combustion of gas, a large amount of air must be introduced to reduce the amount of incomplete combustion product CO, so its excess air coefficient is relatively high. In addition, the diffuser burner requires a large amount of air, and when the air is mixed vigorously at the head, it will produce very loud noise. The advantage of diffusion combustion is that the air and fuel are not mixed in advance, and flashback will not occur. [0003] The head structure of a general fully premixed metal fiber burner is in the form ...
