Description
Technical field
The present invention relates to a kind of structure of burner, particularly a kind of tube furnace burner.
Background technology
Tubular heater is a kind of firepower firing equipment, it utilizes thermal-flame that fuel produces when the burner hearth internal combustion and flue gas as thermal source, the medium that heating is flowed in the boiler tube high speed, make it reach the temperature of process stipulation, to supply with medium needed heat in carrying out process such as fractionation, cracking or reaction, guarantee to produce and normally carry out.Compare with other mode of heating, the major advantage of tubular heater is heating-up temperature height (can reach 1273K), and heat-transfer capability is big and be convenient to operational administrative.
Tube furnace has very important effect at petrochemical plant, and the energy consumption of tube furnace is very high.The energy consumption of tube furnace accounts for 80%～90% in process units.Its investment generally accounts for about 15%, and high reaches 30%.In recent years, the development of tube furnace is very fast, has become one of requisite process equipment in the petrochemical industry in modern age.In addition, since heating furnace when fuel combustion noise and fume emission also environmental pollution cause quite and seriously influence.These factors all must take in when heating furnace designs.
The place that the heating furnace of petrochemical industry tubular heater and other industry is common is that a combustion chamber that is surrounded by refractory material is arranged, and is provided with burner in its bottom or side, and difference is that what to be arranged in stove is heat-transfer pipe, thereby also is tube furnace.The heat that utilizes fuel combustion to produce is heated to required temperature with the processing medium in the flowing pipe.
The primary structure of tube furnace is made up of burner, radiation chamber, convection cell and chimney four parts, and its technical characterictic is:
(1) heated material is inflammable, explosive hydrocarbons, compares with the general industrial stove, and its danger is bigger.
(2) mode of heating is for directly being subjected to fiery formula, burning be gas or liquid.Any leakage part may cause blast or fire.
(3) tube furnace only burns gas or liquid fuel, does not bake fluid fuel.
(4) tube furnace is in operation under the high-temperature and high-pressure conditions, operating condition harshness usually.The heating furnace of general hot type, the wall temperature of boiler tube is at 400～650 ℃.And adding the heating furnace of thermal-reactive, furnace wall temperature is at 850～1000 ℃.Operating pressure wider range, low middle pressure is at 1～10MPa, and the high-pressure hydrogenation heating furnace is up to 18～20MPa.
(5) continuous run in long period, hitless operation, the operation cycle is generally at 1 year to 3 years, the longlyest reaches 5 years.Thereby it is very high to the reliability requirement of heating furnace.
Present tube furnace burner design is unreasonable, and efficient is low.Tube furnace has its particularity, and the past has the burner of a lot of tube furnaces to indiscriminately imitate the burner of other boiler, not design targetedly.The energy consumption of tube furnace is very high, and the pollution of noise pollution that causes in combustion process and combustion product is also very serious, and the noise of tube furnace is mainly from burner.
The structure of burner reasonable in design is the thermal efficiency, the optimization combustion technology that improves tube furnace, adopts advanced burning control scheme, designs more rational burner, has better effects of energy saving and emission reduction.
According to the feature of tube furnace, that specific aim is designed is more reasonable, burner more efficiently, be energy-conservation, synergy, lowly pollute, low noise needs.
Summary of the invention
The purpose of this invention is to provide a kind of tube furnace burner, its advantage be compact conformation, flameholding, adjusting than big, noise is low, can in set up an office firelock and flame detection alarm system; The flame spreadability is good, burning is complete, burning is easy to control.This adapts to current requirement on environmental protection, and more can fuel saving, improves efficiency of combustion.
The present invention is achieved through the following technical solutions:
Tube furnace burner comprises outer wall, air inlet pipe group, air inlet, ignition tip, is provided with the damper that can regulate intake on outer wall.
Be provided with pneumatic booster in the burner bottom; Be provided with steady combustion cover at the burner top; Bottom or sidepiece at burner are provided with fire inspection mounting pipe; Bottom at burner also is provided with flame-observing hole.
Compared with prior art, the invention has the beneficial effects as follows:
(1) the burner scope of application is wide, incendivity natural gas, liquefied gas, coke-stove gas, blast furnace gas, coal gas of converter, Device in Gas and various cracking coal gas etc.;
(2) burning fully, efficiency of combustion is more than 99.5%, and old-fashioned relatively burner is energy-conservation more than 4%;
(3) can realize high-intensity combustion, the volume calorific intensity can reach 1.2 * 104kcal/m
3S;
(4) flame export jet velocity height, flame rigidity is strong;
(5) overcome because of containing flame instability, coking, the obstruction shortcoming that tar, impurity, liquid hydrocarbon etc. cause in the combustion gas.No tempering, take off fiery phenomenon;
(6) be convenient to the reliable high-energy ignition system of installation capability and unify that flame detects and warning system.
(7) can realize combustion air and fuel in certain proportion adjusting by being provided with of damper, make burning more reliable and stable, realize fully automatic operation.
