Abstract

The utility model relates to a highly oil/gas burning hot blast stove in the heat engineering art of the industrial production, which is provided with a steel stove body outer cylinder; the front port of the steel stove body outer cylinder is provided with a combustion device, and the back port is a hot flue gas exit. The utility model is characterized in that an inner cylinder rolled by a heat-proof steel plate is arranged in the stove body outer cylinder; the inner cylinder is shorter than the outer cylinder, and distance is provided between the inner cylinder and the outer cylinder and is formed with a cold air channel; a water level moveable or wobbly fire adjusting plate is arranged in the back section of the stove body outer cylinder relative to the back section of the inner cylinder; a ring shape auxiliary blast device is arranged at the front port of the inner cylinder next to the inwall. The disadvantages of the old type hot blast stove of big volume and weight, unable to move, big thermal inertia, limited burning condition by the system, etc. are overcome by the utility model; the highly oil/gas burning hot blast stove can be used for the heat engineering art of various industries.

Description

The high efficiency fuel fuel gas hot-blast stove

(1) technical field: the utility model relates to a kind of Thermal Equipment in the industrial production, is a kind of high efficiency fuel fuel gas hot-blast stove that is used to provide the hot flue gas of uniform temperature.

(2) background technology: hot-blast stove of the prior art has the body of heater urceolus of steel, on its front port burner is installed, rear port is hot exhanst gas outlet, adopts refractory brick to build the burner hearth liner by laying bricks or stones in the body of heater urceolus, the shortcoming of this structure is that its volume and weight are bigger, can not move, investment is big, and thermal inertia is big, its furnace pressure is by system's control, self is no adjusting device generally, therefore cannot say for sure to demonstrate,prove the burner hearth optimal combustion state, and inconvenience is regulated.

(3) summary of the invention: the purpose of this utility model is to overcome the shortcoming that exists in the above-mentioned prior art, provides a kind of in light weight, and thermal inertia is little, the high efficiency fuel fuel gas hot-blast stove that heat supply temperature and furnace pressure are adjustable.

Concrete scheme of the present utility model is to improve at existing hot-blast stove to form, particularly will have the refractory brick liner cancellation of hot-blast stove now, adopt heat-resisting steel sheet and plate to roll the inner core that forms and in the body of heater urceolus, install, this inner core design is short slightly than urceolus, and between inner core and the urceolus spacing is arranged, form cold air path, in body of heater urceolus back segment, behind the inner core retaining fire adjustable plate that can move horizontally or swing is installed relatively; And annular overfire air device is set at the inner wall of inner core front port.

For strengthening the cooling-down effect of inner core, be furnished with the polylith fin on the inner tank theca described in the utility model.

The existing relatively hot-blast stove of the utility model, its overall dimensions reduce, weight saving (being the 1/5-1/15 of former stove weight), thermal inertia is little, and owing to installed the fiery adjustable plate of retaining, can regulate the pressure and the flue gas heat supply temperature of burner hearth, satisfies the requirement of different thermal technologies.Help the seriation design of product.

(4) description of drawings:

Fig. 1 is a general structure schematic diagram of the present utility model;

Fig. 2 is a general structure left view of the present utility model.

Among the figure: the 1-burner, the 2-overfire air device, 3-body of heater urceolus, the 4-fin, the 5-cold air path, 6-inner core, 7-keep off fiery adjustable plate, the hot exhanst gas outlet of 8-, 9-horizontally moving device.

(5) specific embodiment:

Referring to Fig. 1, Fig. 2, the utility model adopts the general material steel plate of Q235 to roll body of heater urceolus 3, its tail end is hot exhanst gas outlet 8, adopt heat-resisting steel sheet and plate to roll inner core 6, the polylith fin 4 that on inner core 6 outer walls, is welded, inner core 6 is short slightly than urceolus 3 length, diameter less (seeing shown in the figure), adopt gripper shoe to be fixed in one heart in the urceolus 3 inner core 6, the gap is a cold air path 5 between the inside and outside tube, the external air supply device of the front port of cold air path 5.

Load onto burner 1 at the front port of the utility model inner core 6, and annular overfire air device 2 is set at the periphery of burner 1, the front port inwall of inner tube 6.

In the back segment of the utility model body of heater urceolus 3, relatively the rear port of inner core 6 is installed disc and is kept off fiery adjustable plate 7, and this keeps off fiery adjustable plate 7 and is loaded on and has promptly constituted the utility model on the horizontally moving device 9.

Claims

1. high efficiency fuel fuel gas hot-blast stove, it has the steel shell urceolus, on its front port burner is installed, rear port is hot exhanst gas outlet, it is characterized in that: be equipped with in the body of heater urceolus and adopt heat-resisting steel sheet and plate to roll the inner core that forms, inner core is short than urceolus, and between inner core and the urceolus spacing is arranged, form cold air path, in body of heater urceolus back segment, behind the inner core retaining fire adjustable plate that can move horizontally or swing is installed relatively; And annular overfire air device is set at the inner wall of inner core front port.

2. high efficiency fuel fuel gas hot-blast stove according to claim 1 is characterized in that: described inner tank theca is furnished with the polylith fin.
