Description
Technical field
The utility model relates to the burner of gas heating, specifically a kind of combustion heat exchanger.
Background technique
Heat exchanger is widely used in the industrial circles such as petrochemical industry, electric power, environmental protection.Heat exchanger is a kind of the two of different temperatures
The energy-saving equipment that heat transfer between material is realized between kind or two or more fluids is to transmit heat by the higher fluid of temperature
It gives temperature lower fluid, fluid temperature (F.T.) is made to reach the index of flow specification, to meet the needs of process conditions, while being also to mention
One of the capital equipment of high energy source utilization rate.Currently, in order to improve heat utilization efficiency, the combustion heat-exchange of burnt gas wall hanging furnace and water heater
Device is reversely hung Yong installation burning, i.e. full pre-mix condensing.At the positive top of heat exchanger, fuel gas inlet, fuel gas inlet underface are set
For combustion chamber, smoke outlet is set in the positive bottom of heat exchanger, smoke outlet, fuel gas inlet, combustion chamber three vertically correspond to, row
Mouth is flat and small, since the combustion chamber of combustion heat exchanger and fuel gas inlet vertically correspond to, burning when flare and cigarette up walk,
But when, the smoke outlet of combustion heat exchanger is located at bottom, fume exhausting type can only walk from top to bottom, in calorifics principle, heat
Gas and hot cigarette are up walked, and form opposite fume exhausting type, and combustion chamber is sealing, combustion gas from the top of combustion chamber into
Enter combustion chamber, burn in combustion chamber ignition, firepower excessively concentrates on combustion chambers burn, combustion gas meeting during combustion chamber moment burns
A large amount of expansion thermal current is generated, the smoke outlet setting of combustion heat exchanger is too small in bottom and smoke outlet, and moment generates a large amount of
Hot gas can not abrupt release/discharge, hot gas moment by fuel gas inlet flow backwards on the inlet channel of combustion gas, will form herein weight
Multiple hot gas moment flows backwards work, causes lower section firepower insufficient, and heat is small, underheat, forms the water of combustion heat exchanger lower section
The disadvantages of flowing thermal conversion rate.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of of simple structure and strong practicability, structurally reasonable burning
Heat exchanger.
The purpose of this utility model is completed by following technical solution, and a kind of combustion heat exchanger, it mainly includes
Burner and heat exchanger, the burner are the columnar structured of both ends open, and outer surface, which is brushed, one layer of high temperature aluminium paint,
One end of burner is equipped with fuel gas inlet by a transition rotary table, and the other end of burner is connected with one for flue gas to be discharged simultaneously
Transmit the first smoke box of heat；The top of burner, one end of heat exchanger and the first cigarette are arranged in by supporting plate for the heat exchanger
Case connection, the other end are connect by the second smoke box with smoke exhaust pipe, and one end of the smoke exhaust pipe is connected to the upper end of the second smoke box,
A smoke pipe flange has been bolted in the other end, more heat exchanger tubes is provided in the heat exchanger, and between every heat exchanger tube
It is provided with the gap passed through for flue gas.
As preferred: one group of heat sink strip for avoiding the first smoke box from overheating is provided on the outer wall of first smoke box, it is described
Heat sink strip is vertically arranged on the outer wall of the first smoke box.
As preferred: the bottom of the burner is provided with an arc-shaped backplate, the radian of the arc-shaped backplate and burning
The radian of device outer diameter is consistent, and the bottom of arc-shaped backplate is installed with a support frame.
As preferred: it is characterized in that, support frame as described above is made of channel steel.
