Abstract
The gas furnace head includes the furnace jacket which has the disk upper body with the hollow. The upper body is slant from the inner side to up and the circles have the holes set between vessel supporters. The supporter used to set the food cooking vessel is set on the upper body in the same distance. The top of the furnace jacket is the heat-retaining ring with the hollow cylinder which the circle is set with the holes. The ring with the hunch circle is set between every supporter to make the out air in through the gap to burn absolutely. When the gas emitted from the mouth, the top and the hunch can make the gas flow uniform. So the gas flow is divided into two directions when it passes the hunch. So the gas does not loss and the heat energy is 2 times of the ordinary gas furnace head.
Description
Technical field
The present invention relates to the coal-gas range head of mechanical engineering field.
Background technology
Traditional coal-gas range head or burner have some basic members, comprising: the fuel gas supply valve; Air inlet pipe; And gas mixer chamber, be used for fuel is mixed mutually with air; And the outlet of passing lid or cover.This lid has a plurality of holes, can discharge mist, is used for burning in an orderly manner in combustion process.Coal-gas range head or burner generally include: gas mixing tube and gas storage chamber, the both has cylindric medial and lateral shape, wherein gas storage chamber is lived by the annular cover that therefrom sections of hollow or cover cap, the inner surface of lid should be smooth, makes gas upwards to be used for burning by arriving air vent.Gas storage chamber and lid are arranged in the boiler clothing.Usually can produce many frictions, under these circumstances, speed forfeiture, mobile not smooth.
Summary of the invention
According to coal-gas range head of the present invention or burner, comprising: boiler clothing as encapsulation and holding portion, is used for the install combustion head; Protect the heat ring, can stop heat outwards to run off, and make the outside air circulation can promote combustion process.Boiler clothing has the dish type upper body of hollow, and wherein the upper body is acclivitous from the inside edge, and the position between each container support frame has the hole.The upper body of boiler clothing has container support frame or leg, and it equally spaced is provided with mutually, is used for the food cooking container is placed on stove.
The top of boiler clothing lower body is the guarantor's heat ring with flat cylindric integral body of hollow, its side face centre has pore, the position between the container support frame around the apical margin of heat-retaining wall wherein, has equally spaced protuberance, make outside air to flow into, thereby obtain combustion process more completely from the breach between each protuberance.
The inside of protecting the heat ring be inverted dish type, the center is the bell of cylindrical cavity, wherein bell has outer surface, as the outer rim at the reception edge of stacked gas mixer chamber; And have the interior perimeter surface as inner edge, its middle part is provided with cylindrical cavity, is used to insert the air feed combustion head; Lid or stove have from outer rim and extend into the first lifting layer that has outside coal gas supply hole and have the upper surface of rise of the second lifting layer of inboard coal gas supply hole.
Coal gas is supplied with most of zone that burner is installed in the boiler clothing inboard, and is covered with by bell, and it has the mixing tube that extends to boiler clothing one side.Combustion head is arranged on the boiler clothing with being inclined upwardly slightly, in order to obtain maximized flow efficiency in the shortest distance and the combustion process.Coal gas is supplied with head and is had long hollow cylinder body part, and wherein a side end portion is an air inlet pipe, and the coal gas of opposite side supply head has cup-shaped circular curve ectosome, its whole continuity in extension from body part.
The top centre that coal gas is supplied with head is cylindric crucible, and its place ahead outer regions wherein is the thick protuberance that the root edge from cylindric crucible stretches out.After coal gas discharged from gas port, owing to provide the curved protuberance in top and bottom that are positioned at coal gas supply chamber extension interior zone curved protuberance, coal gas stream was by more orderly distribution.Pipe is extended and enlarges the chamber that becomes two passages in addition.So, when the curved protuberance of top by inside, coal gas supply chamber extension of coal gas stream, bottom, by the clear and definite both direction that is divided into, the steering current end makes progress and flows, and the described coal gas stream that wherein is separated into both direction is forced to flow upward and arrives the coal gas supply opening with first lifting protuberance.Then, upward move, pass first second lifting that promotes the protuberance back and swell by the first coal gas flow direction that promotes protuberance.Implicit principle is by two stoves of a supply source supply, thereby efficiency of combustion is doubled.
An object of the present invention is to control the form and the direction of coal gas stream in the coal gas gas collection manifold, to improve its speed.In addition, when coal gas stream passes through gas supply pipe, must be divided into both direction clearly, because coal gas stream can flow backward and become annular, its end is directed upwards, thereby does not have coal gas to run off.The heat of the flame that the coal gas supply hole discharges is maintained by annulus, thereby does not have thermal loss, and outside air will be used to improve efficiency of combustion simultaneously.
Another object of the present invention is to produce available thermal energy as much as possible.By coal-gas range head of the present invention,, thereby reduced the coal gas use amount because the amount of available thermal energy is the twice of common coal-gas range head in the combustion process.The coal smoke that imperfect combustion produces reduces too, makes minimum contamination and environment is not damaged.In addition, this gas burner is compared with traditional gas burner, can save the time that coal gas and cooking food spend, thereby has saved a limited number of coal gas energy.
