Abstract

The utility model provides an ejection combustor. More than three fuel gas inlet pipes are mounted in the lower end of a Venturi premixing pipe with a Venturi structure; a furnace end is connected to the extension end at the upper part of the Venturi premixing pipe; a ceramic plate is mounted in the furnace end; a plurality of square combustion holes are formed on the ceramic pipe; and a catalyst coating is coated at the upper part of the ceramic plate. The utility model has the characteristics of strong firepower, wide adjustable range, good combustion performance, full combustion and energy conservation, and is suitable for the combustion and heating of larger combustors.

Description

The injection burner

Technical field

The utility model provides the combustion heat supplying apparatus in thermal technology field, specifically injection burner.

Background technology

Before the utility model proposes, kind of an infrared burner is arranged, its structure is that a combustion gas inlet pipe is installed in air inlet pipe, upper end cover is with the ceramic wafer of several circular holes.Combustion gas forms flammable premixed gas through air inlet and air pre-mixing, by the aperture ejection of ceramic wafer, is lighted under the effect of kindling material, is used for the burning heating.The shortcoming that this burner exists is, combustion gas inlet pipe kind is only installed a Gas Pipe and nozzle, and adjustable extent is little, can not increase at any time according to the needs of firepower or dwindle.Also have, the hole on the ceramic wafer is a circular hole, and throughput is little on unit are.Ceramic wafer is general heat-stable ceramic plate in addition, and burning is not had facilitation.So this kind burner uses and is restricted, can only be as family expenses.

Summary of the invention

For the shortcoming of the ceramic wafer burner that overcomes existing injection distribution, the utility model provides the injection burner.This burner is installed the coating ceramic plate of square hole by combustion gas inlet pipe and the respective nozzles more than three is installed at the venturi pipe end at the fire door position of upper end, solve the technical problem of burner combustion performance.

The scheme of the utility model technical solution problem is: the combustion gas inlet pipe more than three is installed in the inside, lower end of the venturi premix barrel with Venturi tube structure, is connected with burner in the upper enlarged end of venturi premix barrel, ceramic wafer is installed in burner.

Earthenware is provided with several square burner ports, scribbles catalyst coat on ceramic wafer top.

The utility model burner has that firepower is violent, and adjustable extent is big, has good burning performance sufficient combustion and energy-conservation characteristics.Suitable bigger burner combustion heating is used.

Among the figure, 1. venturi premix barrel, 2. burner, 3. ceramic wafer, the square burner port of 3.1., 3.2. catalyst coatings, 4. combustion gas inlet pipe.

The specific embodiment

According to the figure, the combustion gas inlet pipe 4 more than three is installed in the inside, lower end of the venturi premix barrel 1 with Venturi tube structure, is connected with burner 2, ceramic wafer 3 is installed in burner in the upper enlarged end of venturi premix barrel.

Earthenware 3 is provided with several square burner ports 3.1, scribbles catalyst coat 3.2 on ceramic wafer top.

On the combustion gas inlet pipe, control valve is installed.

The utility model course of work

Combustion gas is during by the combustion gas inlet pipe, behind the contraction flow region that arrives Venturi tube under the effect of certain flow rate, spread, produce suction function simultaneously, and the drive outside air enters into the top of Venturi tube in company with combustion gas, form pre-mixing gas combustion, pre-mixing gas combustion, is lighted under the effect of kindling material by the square burner port on the ceramic wafer.Because ceramic wafer is provided with several square burner ports, throughput is big, so burning area is big, firepower is violent, sufficient combustion.Owing to be coated with catalyst coatings on the ceramic wafer, the flame that burning is produced can be converted to infra-red radiation, and make fuel combustion abundant, thereby improve the efficiency of combustion of fuel.

According to the needs of firepower, can open a combustion gas inlet pipe, also can open two combustion gas inlet pipes, also can open three combustion gas inlet pipes, and, the aperture that also can regulate each valve, so it is adjustable extent is big, flexible and convenient to use.

The utility model suits to use on bigger combustion stove.
