Abstract
A horizontal sub-high pressure double-drum oil-gas dual-purpose boiler comprises a membrane type water cooling hearth and an economizer. A light tubing boiler wall is arranged on the periphery of the membrane type water cooling hearth, and a burner connector is arranged on the side face of the light tubing boiler wall. The membrane type water cooling hearth is composed of a front wall membrane type wall, a rear wall membrane type wall, a left wall membrane type wall, a right wall membrane type wall, a middle wall membrane type wall, an upper drum and a lower drum, wherein the upper drum and the lower drum are horizontally arranged. A front convection tube bank, a superheater and a rear convection tube bank are sequentially arranged in the membrane type water cooling hearth from front to rear, and the front convection tube band, the superheater and the rear convection tube bank are located between the upper drum and the lower drum. The horizontal sub-high pressure double-drum oil-gas dual-purpose boiler is compact in structure and high in stability; in use, flue gas sequentially passes through the rear convection tube band, the superheater and the front convection tube bank in the membrane type water cooling hearth and then is discharged out through the economizer, and the structure is applicable to the oil-gas dual-purpose boiler with temperature higher than medium temperature and pressure higher than medium pressure; because the upper drum and the lower drum are designed to be horizontal, the using amount of steel can be greatly saved, and equipment cost is reduced.

Technical field
The utility model belongs to oil-gas two-purpose boiler technology field, particularly a kind of sub-high pressure double-barrel transverse formula oil-gas two-purpose boiler.
Background technology
At present, traditional two drum fast-assembling oil-gas two-way boilers can only be accomplished 2.5Mpa following (low pressure), and its drum wall thickness is all below 30mm.While up increasing from 2.5Mpa due to boiler pressure, need to heat-treat drum, and cannot weld, and expanded joint bothers, workload is large, cost is high.Therefore, general two drum fast-assembling oil-gas two-way boilers can only accomplish below 2.5Mpa, and oil-gas two-way boiler more than medium temperature and medium pressure often needs to be designed to vertical single barrel structure, and this structural steel consumption is large, high cost.
Utility model content
The purpose of this utility model be to provide a kind of compact conformation, sub-high pressure double-barrel transverse formula oil-gas two-purpose boiler.
For achieving the above object, the technical solution of the utility model is: a kind of sub-high pressure double-barrel transverse formula oil-gas two-purpose boiler, comprise the economizer that film-type water-cooling burner hearth is connected with film-type water-cooling burner hearth one side, film-type water-cooling burner hearth is arranged with light-duty tube outward, and a light-duty tube wherein side is provided with combustor interface; Described film-type water-cooling burner hearth by front wall membrane wall, rear wall membrane wall, left wall membrane wall, right wall membrane wall, in wall membrane wall and horizontally disposed upper drum and lower drum form, upper drum is positioned at left wall membrane wall upper inner, and lower drum is positioned at left wall membrane wall lower inside; In film-type water-cooling burner hearth, be provided with successively from front to back front convection bank, superheater and rear convection bank, front convection bank, superheater and rear convection bank are between upper drum and lower drum.
Described superheater is supported by two row's convection banks.
Described film-type water-cooling burner hearth and economizer bottom are equipped with base.
Described economizer is finned economizer, and it adopts independent film blocking channel structure.
Compared with prior art, advantage of the present utility model is:
1, the utility model comprises the economizer that film-type water-cooling burner hearth is connected with film-type water-cooling burner hearth one side, and film-type water-cooling burner hearth is arranged with light-duty tube outward, and a light-duty tube wherein side is provided with combustor interface; Described film-type water-cooling burner hearth by front wall membrane wall, rear wall membrane wall, left wall membrane wall, right wall membrane wall, in wall membrane wall and horizontally disposed upper drum and lower drum form, upper drum is positioned at left wall membrane wall upper inner, and lower drum is positioned at left wall membrane wall lower inside; In film-type water-cooling burner hearth, be provided with successively from front to back front convection bank, superheater and rear convection bank, front convection bank, superheater and rear convection bank are between upper drum and lower drum, its compact conformation, stability is strong, during use, flue gas is warp convection bank later successively, superheater and front convection bank in film-type water-cooling burner hearth, then through economizer, discharge, this structure is applicable to oil-gas two-way boiler more than medium temperature and medium pressure, upper drum and lower drum design for Horizontal type, can greatly save rolled steel dosage, reduce equipment cost.
2, superheater is supported by two row's convection banks, simple in structure, and it is convenient to change.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Sub-high pressure double-barrel transverse formula oil-gas two-purpose boiler as shown in Figure 1 and Figure 2, it comprises the film-type water-cooling burner hearth 2 being arranged on base 1 and is arranged on the economizer 8 on base 7, film-type water-cooling burner hearth 2 is connected with economizer 8.Outside film-type water-cooling burner hearth 2, be arranged with light-duty tube 3, light-duty tube 3 leading flanks are provided with combustor interface 28.
Film-type water-cooling burner hearth 2 by front wall membrane wall 21, rear wall membrane wall 22, left wall membrane wall 23, right wall membrane wall 24, in wall membrane wall 25 and horizontally disposed upper drum 26 form with lower drum 27, upper drum 26 is positioned at left wall membrane wall 23 upper inner, and lower drum 27 is positioned at left wall membrane wall 23 lower inside.Convection bank 6 before the inside of film-type water-cooling burner hearth 2 is provided with from front to back successively, superheater 4 and rear convection bank 5, front convection bank 6, superheater 4 and rear convection bank 5 are between upper drum 26 and lower drum 27.Superheater 4 is supported by two row's convection banks 9.
In the present embodiment, economizer 8 is finned economizer, it adopts independent film blocking channel structure, the tube bank of low-temperature zone economizer adopts the material of 09CrCuSb, when guaranteeing heating surface area, can reduce thermal stress, fin structure can be realized automatic welding simultaneously, to reduce the weld defect existing in manual welding; 8 minutes two stage arrangement of economizer, low-temperature zone adopts the material of ND steel (09CrCuSb), can effectively alleviate cold end corrosion; Meanwhile, economizer 8 adopts Puncture Tube box structure, can the in the situation that of not blowing out, cut off economizer 8, keeps in repair, and convenient maintenance, does not affect the normal operation of boiler.Upper drum 26, lower drum 27 and convection bank are all the good rear bulk heat treatmets of welding, can realize fast-assembling, greatly cost-saving.
When the utility model is used, flue gas successively through convection bank 5 later, superheater 4 and front convection bank 6, is then discharged through economizer 8 in film-type water-cooling burner hearth 2.
