The chamber combustion oil gas boiler system with the built-in steam air heater is characterized in that the steam air heater is arranged on the lower portion of the space between the rear wall of the hearth arranged in the steel frame and the tail vertical shaft, the steam air heater is supported through a support, an inlet formed in the lower end of the steam air heater is connected with a cold air duct, an inlet of the cold air duct is directly connected with an outlet of an air blower, an outlet formed in the upper end of the steam air heater is connected with a hot air duct, and an outlet of the hot air duct is connected with an air inlet of the air preheater. According to the chamber combustion oil gas boiler system with the built-in steam air heater, due to the fact that the steam air heater and the related air ducts of the steam air heater are arranged reasonably, the space between the rear wall of the hearth and the tail vertical shaft is made full use of, arrangement of the cold air duct of the steam air heater is optimized, and the occupied area of the chamber combustion oil gas boiler system is reduced; the length of the cold air duct of the steam air heater and the length of the hot air duct of the steam air heater are reduced, metal steel consumption of the air ducts of the steam air heater is reduced, and air movement resistance on the inlet of the steam air heater is reduced.
Description
Technical field
The utility model relates to a kind of chamber Methods of Oil-Gas Fired Boiler system, specifically a kind of chamber Methods of Oil-Gas Fired Boiler system with built-in steam air heater.
Background technology
Current China part boiler user; especially the user of some annual temperature difference larger areas; for preventing the cold end corrosion of various corrosivity compositions to air preheater cold-end air in cold air; conventionally can before air preheater, install steam air heater additional; utilize turbine low pressure cylinder to draw gas and heat the steam warming machine of cold air; or the hot water steam air heater that utilizes systemic circulation hot water heating cold air improves the temperature of air preheater import cold air, to prevent the generation of cold end corrosion.
But as a rule; no matter be, adopt steam warming machine or hot water steam air heater; general user can be arranged in steam air heater boiler outside conventionally, and this just means that the cold wind that accesses air preheater must first enter steam air heater through long segment pipe again, sends into air preheater after heating again.This arrangement, because cold air flow process is longer, will certainly increase duct resistance, causes steam generator system floor space to increase simultaneously, and air channel metal consumption increases.Therefore, for chamber Methods of Oil-Gas Fired Boiler, how the layout of steam air heater and boiler integral arrangement are considered every possible angle, optimized, just become important problem.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of chamber Methods of Oil-Gas Fired Boiler system with built-in steam air heater is provided, this chamber Methods of Oil-Gas Fired Boiler system optimization steam air heater cold air duct arrange, reduced steam generator system floor space, reduce steam air heater air channel metallic steel consumption, reduced steam air heater inlet air flow resistance.
The technical scheme providing according to the utility model: the chamber Methods of Oil-Gas Fired Boiler system with built-in steam air heater, comprise burner hearth, tail vertical well, air preheater and steam air heater, burner hearth supports by steelframe, tail vertical well is positioned at burner hearth rear, air preheater is arranged in tail vertical well, it is characterized in that: described steam air heater is arranged on the bottom in space between burner hearth rear wall in steelframe and tail vertical well, and steam air heater passes through bracket supports; The import of steam air heater lower end connects cold air duct, and cold air duct import is directly connected with blower export, and the outlet of steam air heater upper end connects hot-flow flue, and hot-flow flue outlet is connected with the air intlet of air preheater.
As further improvement of the utility model, described lower furnace portion is middle closing-in structure.
As further improvement of the utility model, described steam air heater adopts hot water steam air heater or steam warming machine, its inner horizontal is arranged many spiral fin coils, and spiral fin coil lower end connects import header by elbow, and spiral fin coil upper end is by elbow connection outlet header.
As further improvement of the utility model, described steam air heater sidewall is provided with seal casing.
compared with prior art, advantage is the utility model:the utility model, by the reasonable Arrangement to steam air heater and relevant air channel thereof, takes full advantage of the space between burner hearth rear wall and tail vertical well, has optimized steam air heater cold air duct and has arranged, has reduced steam generator system floor space; Shorten the length in the hot and cold air channel of steam air heater, reduced steam air heater air channel metallic steel consumption, reduced steam air heater inlet air flow resistance.

Fig. 1 is the chamber Methods of Oil-Gas Fired Boiler system architecture schematic diagram of the utility model embodiment.
Fig. 2 is the enlarged diagram at steam air heater position in Fig. 1.
Fig. 3 is the left view of Fig. 2.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Fig. 1 ~ Fig. 3: the chamber Methods of Oil-Gas Fired Boiler system with built-in steam air heater in embodiment mainly comprises burner hearth 1, tail vertical well 3, air preheater 4 and steam air heater 6, burner hearth 1 supports by steelframe 2, oil-gas burner 13 is installed on burner hearth 1, tail vertical well 3 is positioned at burner hearth 1 rear, air preheater 4 is arranged in tail vertical well 3, described steam air heater 6 is arranged on the bottom in space between burner hearth 1 rear wall in steelframe 2 and tail vertical well 3, and steam air heater 6 supports by support 7; Steam air heater 6 lower end imports connect cold air duct 8, and cold air duct 8 imports are directly connected with blower export, and steam air heater 6 upper end outlets connect hot-flow flue 5, and hot-flow flue 5 outlets are connected with the air intlet of air preheater 4.
As shown in Figure 2 and Figure 3, the steam air heater 6 of the utility model embodiment has been selected hot water steam air heater 6, its inner horizontal is arranged many spiral fin coils 10, and spiral fin coil 10 lower ends connect import header 9 by elbow, and spiral fin coil 10 upper ends are by elbow connection outlet header 12.In addition, in order to improve insulation and sealing property, described steam air heater 6 sidewalls are provided with seal casing 11.During work, hot water, in the spiral fin coil 10 in import header 9 enters steam air heater 6, carries out by outlet header 12, being discharged after heat exchange with the cold air that enters steam air heater 6 again.
During concrete application, cold wind, after air blast bloats, directly enters the cold air duct 8 that is arranged in steelframe 2 inside, then enters steam air heater 6, after heat exchange is carried out with hot water in steam air heater 6 inside, become the hot blast with uniform temperature, then by hot-flow flue 5, enter air preheater 4 again.Take full advantage of like this space at burner hearth 1 rear portion, reduced steam generator system floor space, shortened the length of cold air duct 8, reduced boiler air duct metal consumption, reduced the resistance of cold wind.
