Abstract

The utility model discloses a hydrogen oven, which comprises a heat preservation furnace body, air spraying mouths, an air supplying pipe and a heat insulating plate, wherein the heat preservation furnace body is divided into an upper combustion chamber and a lower heat insulating chamber by the heat insulating plate. The air supplying pipe is positioned at the heat insulating chamber below the heat insulating plate, one air inlet end of the air supplying pipe is provided with a straight pipe and the other end is bent into a circle and is closed at the end. A plurality of air spraying pipes are evenly welded on a circular bent pipe, and the other end of every air spraying pipe is connected with the air spraying mouth. A plurality of air spraying mouths of the utility model are tilt upwards with a certain angle, one air spraying mouth is only ignited to ignite other air spraying mouths and firing is easy. Simultaneously, hydrogen enters the air supplying pipe and then is jetted through the air spraying mouths to play flow dividing action and to prevent too long flame from directly combusting a pan bottom after single pipe hydrogen is combusted.

Description

A kind of hydrogen stove

Technical field

The utility model relates to a kind of hydrogen stove that utilizes hydrogen or hydrogeneous gaseous mixture to do fuel.

Background technology

At present, the requisite kitchen range of daily life mostly are gas range, liquefied gas cooker, natural gas range, the used combustion gas of these kitchen range all produces to be had the waste gas that dyes of ring and uses utilization efficiency of heat energy poor environment, these kitchen range need be connected with air feed bottle with steam line simultaneously, exist pipeline or gas cylinder to leak the danger of poisoning or exploding.

Hydrogen Energy is environmental protection, the clean energy resource of 21st century, hydrogen and oxygen combustion only produce water, the preparation of hydrogen at present can be passed through method preparations such as water electrolysis hydrogen production, biomass hydrogen preparation, gas renormalizing hydrogen manufacturing, solar photoelectric hydrogen manufacturing, wherein water electrolysis hydrogen production accomplished promptly to produce promptly with, use before and after equal technical merits of storage of hydrogen not, so hydrogen can to replace coal gas, liquefied gas, natural gas as a kind of New-type fuel of environment-protecting clean safety be practicable.

Because the flame temperature that the heat that combustion of hydrogen produces is concentrated, penetrated can be up to 2800 degree and firepower not only carefully but also long, easily the bottom of a pan is burnt, need the above supply gas pressure of 0.6Mpa just can light during combustion of hydrogen, the too high meeting of steam line temperature causes back draft, therefore kitchen range commonly used at present all can not use hydrogen to do the fuel supply, must design the novel kitchen range that are fit to combustion of hydrogen.

The utility model content

The purpose of this utility model is to provide a kind of hydrogen stove that uses hydrogen or hydrogeneous gaseous mixture to do fuel, to replace contaminated environment, to have gas range, liquefied gas cooker, the natural gas range of the latent string of safety, solve in the hydrogen heat quantity set simultaneously, single-point temperature height, be difficult for technical barrier such as being lighted by the electronic striking device.

For realizing above-mentioned purpose, the technical solution of the utility model is: comprise thermal insulation furnace body, air nozzle, air supply pipe, thermal insulation board, thermal insulation board is divided into upper combustion chamber, following two parts of heat-insulating room with thermal insulation furnace body, air supply pipe is positioned at the heat-insulating room of thermal insulation board below, air jet pipe one end vertical welding is connected on the air supply pipe, and the other end passes thermal insulation board and links to each other with air nozzle.

In the above-mentioned hydrogen stove, an end of described air supply pipe air inlet is a straight tube, and other end circumflexion and sealing endways evenly are welded with many air jet pipes on circular winding pipe, and the air jet pipe other end links to each other with air nozzle.

In the above-mentioned hydrogen stove, the angle of described air nozzle and air jet pipe is greater than 90 degree, and less than 180 degree, the line segment that air nozzle is become in the horizontal plane projection intersects the angle of spending less than 90 with the tangent line of the solder joint position of corresponding circular winding pipe.

The beneficial effects of the utility model: after 1) hydrogen enters from air supply pipe, penetrate, play shunting action, avoid behind the single tube combustion of hydrogen flame oversize and at the bottom of the straight enamelware pot through a plurality of air nozzles; 2) thermal insulation furnace body is separated by thermal insulation board, and hydrogen is in the high-temp combustion Indoor Combustion, and main air supply pipe is in the low temperature heat-insulating room, avoids causing because of the air supply pipe temperature is too high tempering; 3) the pan frame is after above the high temperature combustors of thermal insulation furnace body, and it is indoor that the energy that hydrogen is produced is isolated in high-temp combustion, reduce to around heat diffusion, improved utilization efficiency of heat energy; 4) inclination certain angle in air nozzle upper end can be avoided at the bottom of the straight enamelware pot of flame, and the gas of all air nozzles ejections intersects same angle in twos, and the electronic striking device only need be lighted an air nozzle other air nozzles that can ignite, thereby is easy to igniting.
