Description
Technical field
The utility model relates to gas kitchen ranges, particularly a kind of gas preheater with obvious energy saving effect.
Background technology
Combustion gas (natural gas, oil liquefied gas, coal gas etc.) is the valuable source of national economy, these resources all belong to the disposable energy, and China's resource scarcity, according to the United Nations's iea prediction, tellurian petroleum resources will exhaust in have more than is needed 50 years, and China only account for the whole world for each person workable reserves 7 percent.The energy not only involves the interests of the state and the people, and also is related to national security, and is energy-conservation imperative.New alternative backwardness, the historical development trend of being not only of energy-efficient alternative highly energy-consuming is especially for keeping Chinese national economy to continue pressing for of stable development, so it is particularly important efficiently to save technology.
The plenum system of the various gas kitchen ranges that domestic market sale at present and family and public place use, the burning form all is the history that comes from the centuries, all is that ubiquity the oxygen supply deficiency for cool fuel gas buring, burning velocity is slow, incomplete combustion, flame temperature is low, and firing rate is slow, heat utilization efficiency is low, amount of consumed gas is big, and environmental pollution is big, and easily burns shortcomings such as pot wall.The energy-saving stove that buy present domestic market, energy-saving effect is all not remarkable.
Summary of the invention
The purpose of this utility model provides a kind of gas-cooker that changes and realizes energy-conservation gas preheater for combustion gas mode and combustion system.
The technical solution of the utility model is as follows:
A kind of gas preheater is characterized in that: comprise the annular slab with annular preheating inner chamber, annular slab is provided with the air inlet and the exhaust outlet that are connected with escape pipe with air inlet pipe respectively that is communicated with annular preheating inner chamber, and the mesopore of annular slab is enclosed within the combustion head outside.
Described annular slab is inversed taper platform shape or cylindrical shape.
Described air inlet and exhaust outlet are symmetrical arranged with the annular slab center of circle.
Described annular slab preheating inner chamber radially is provided with air flow partition, and described air inlet and exhaust outlet are separately positioned on the air flow partition both sides.Described air flow partition is a compartmentation strip in the chamber, or is arranged on the outer partition that forms the indent nick shaped outside the chamber.
Described mesopore bottom is provided with the chassis, and tray bottom is provided with the oxygenating hole.
The heat energy of the cool combustion gas of gas preheater preheating, to be exactly kitchen range self when burning distributed be lost to surrounding space and be preheated the heat energy that device is isolated in inner chamber, combustion gas molecule after the preheating increases, density reduces, and compares with the cool combustion gas of equal in quality, under equal conditions can sneak into different quality (manys') oxygen, impel mist before burning, to reach the full state that closes, realize conflagration with this, completing combustion has realized recycling heat energy simultaneously again.
The utility model also has the following advantages:
One, changed the physical property of combustion gas, improved the dissolved oxygen ability of combustion gas self: utilize combustion gas in combustion process to the bottom of a pan peripheral space distribute heat and penetrate heat to the width of cloth of the following peripheral space in the bottom of a pan and come preheated fuel gas self, combustion gas obtains heating the back molecule and increases, density reduces, improved the dissolved oxygen ability of combustion gas self, in the combustion gas of equal quality, can dissolve in more oxygen, realized combustion gas conflagration with this, completing combustion improves flame temperature; Thoroughly changed the sort of burning form of supplying with oxygen while burning of traditional burner.
Two, take sealed burning, reduce radiating surface, reduce cold-hot air convection, realize reducing heat distributes loss in air purpose, improved heat utilization efficiency with this;
Three, recycling heat energy: the heat energy that utilizes combustion gas to distribute loss in combustion process has heated cool combustion gas, heated combustion gas has been heated combustion head after entering into the combustion head of kitchen range, heated simultaneously the cool oxygen that sucks again, to making the mist that is injected to the low burning of pot not only is not the cold air of heat absorption, but can also directly give the thermal current of pot heating, make the cooking bottom temperature raising of totally having got back, reach energy-conservation purpose with this;
Four, contour structures is succinctly attractive in appearance.
