Abstract
The utility model relates to a double-cylinder radiation chamber heating furnace, which is composed of the following components: two radiation chambers with same structures, a convection chamber, combustors, radiation furnace pipes, convection furnace pipes and a chimney. The radiation chambers with same structures respectively have a cylinder-shaped structure and are parallelly placed vertically. The radiation furnace pipes are vertically arranged in the radiation chamber along the periphery of an inner wall of each cylinder. The combustors are uniformly provided at the bottom of the radiation chambers through a mode of vertically upward mode. The convection chamber has a box-type structure and is symmetrically mounted at the tops of two radiation chambers. The bottom of the convection chamber is communicated with the radiation chambers through transition sections so the flue gas of the double-cylinder radiation chamber can enter the convection chamber uniformly and symmetrically. The convection furnace pipes respectively have a studded-tube-shaped structure and are horizontally placed in the convection chamber. The chimney is provided at a central part of the top of the convection chamber. The heating furnace with the structure can reduce occupation area of a high-load heating furnace; consumption amount of the steel bar; and maintenance space of the heating furnace. Furthermore the double-cylinder radiation chamber heating furnace has the following advantages: simple structure, high flexibility, high practicability, etc.
Description
Technical field
(greater than 32MW) two cylinder radiation chamber heating furnace when the utility model relates to a kind of high heat load.
Background technology
Along with the development and the environmental protection requirement of national economy, the oil plant device is gradually to scale, large scale development.As a kind of heating equipment of oil plant, heating furnace accounts for about 15～25% of the whole technological equipment investment of oil plant.Using maximum in oil plant is " single cylinder radiation chamber+convection cell ", below " heating furnace " mentioned in this article, all refer to " two cylinder radiation chamber heating furnace " as specified otherwise not.
At present, along with the oil plant treatment scale is increasing, the also corresponding thereupon increase of the thermic load of heating furnace generally all will be selected single cylinder radiation chamber heating furnace or batch-type furnace by than choosing greater than the heating furnace of thermic load 32MW.But the batch-type furnace steel consumption is big, complex structure, and floor space is big, and boiler tube support member consumption is big.
Increase the requirement that back heating furnace thermic load increases for satisfying the oil refining scale, simple way is exactly the vertical batch-type furnace that design volume is huge, steel consumption is big, to satisfy the thermic load needs.The little requirement because domestic land supply growing tension, claimed apparatus floor space are tried one's best can design two cylinder radiation chamber heating furnaces.Because under the same volume conditions, the cylindrical structure minimum that takes up room, consumptive material is economized most, and structure is more stable.
The utility model content
The purpose of this utility model is: the two cylinder radiation chamber heating furnaces under a kind of high heat load condition are provided, do not increase investment and take up an area of face situation under, adopt two cylinder radiation chamber heating furnace structures, realize and the same thermic load of vertical batch-type furnace; But structure is compact more; The flexibility of stringing is bigger, no matter how many numbers of tube passes is, and can both flexible arrangement; The steel alloy consumption still less.
Described in the utility model pair of cylinder radiation chamber heating furnace is made up of the radiation chamber of two same structures, convection cell, burner, radiating furnace tube, convection coil and a chimney; The radiation chamber of two same structures is a cylinder type, and parallel the setting placed; Radiating furnace tube is arranged vertically in radiation chamber along the cylinder inner wall circumference; Burner is evenly arranged in the bottom of radiation chamber in the mode of burning vertically upward; Convection cell is a case structure, the top that is erected at two radiation chambers of symmetry, and the bottom is communicated with radiation chamber by changeover portion, makes the flue gas of two cylinder radiation chambers can enter convection cell symmetrically; Convection coil is the studded tube structure, and is horizontally disposed in convection cell; Chimney is positioned at the convection cell crown center.
The operation principle of described in the utility model pair of cylinder radiation chamber heating furnace: fuel is emitted elevated temperature heat by the burner combustion that is positioned at the bottom of each cylinder radiation chamber, pass through radiation mode, heat transferred is positioned at the radiating furnace tube of cylinder along circumference, high-temperature flue gas is by being radiated the changeover portion of convection current then, arrive convection cell, wash away convection coil equably, by the convection heat transfer' heat-transfer by convection mode, the heat transferred convection coil, satisfy the heat of process unit needs.
The application of a kind of pair of cylinder radiation chamber heating furnace:
Radiating furnace tube, is arranged vertically in each cylinder interior along circumference, and burner burns vertically upward, hot flue gas is full of high-temperature flue gas because draft is upwards flowed in the burner hearth, give the radiation chamber boiler tube heat radiation, the high-temperature flue gas that each radiation chamber comes out enters convection cell symmetrically.This structure can be arranged the number of tube passes of heating furnace tube neatly, under the situation of same single side radiation, makes to take up an area of and saves more compact structure most.
The utility model heating furnace can satisfy the requirement of high throughput, high heat load.
The utility model possesses following beneficial effect:
1, under the same process heat burden requirement, adopts this structure, can reduce the projection floor space.
2, steel consumption is lower, reduces investment outlay;
3, the heat resisting steel consumption still less;
4, the flexibility of stringing is bigger.
5, to overhaul needed space few for boiler tube.
The utility model has adopted a kind of heating furnace structure of compactness, has both satisfied the process heat burden requirement, has reduced investment and occupation of land again.This is a kind of new construction at high load capacity heating furnace design, and thermal discharge is big, simple in structure, small investment, construction are easy, but the workshop burst make, but also characteristics such as site operation have good application prospects in the heating stove equipment of oil refining apparatus.

The specific embodiment
Described in the utility model pair of cylinder radiation chamber heating furnace is made up of radiation chamber A5 and radiation chamber B6, convection cell 7, burner 1, radiating furnace tube 2, convection coil 4 and a chimney of two same structures; The radiation chamber of two same structures is a cylinder type, and parallel the setting placed; 132 radiating furnace tubes divide two cylinder radiation chamber 12 tube sides to be arranged vertically in radiation chamber along the cylinder inner wall circumference; 16 burners are installed in the bottom of radiation chamber in the mode of burning vertically upward; Convection cell is a case structure, the top that is erected at two radiation chambers of symmetry, and the bottom is communicated with radiation chamber by changeover portion 3, makes the flue gas of two cylinder radiation chambers can enter convection cell symmetrically; Convection coil is 19 rows, and the studded tube structure of 16 pipes of every row is horizontally disposed in convection cell; Chimney is positioned at the convection cell crown center.
