Abstract

The utility model relates to the technical field of a boiler, specifically a heat-conducting vertical heating boiler. The utility model uses a vertical boiler grate as a conducting heat exchange element to carry out heat exchange; because the vertical boiler grate can provide enough air and causes fuel contacting the air to be completely combusted, the heat exchange quantity in actual combustion is large, and the combustion intensity and the heat intensity of unit area are large. Compared with the traditional vertical boiler, the utility model has the advantages of small ground occupation and light weight, and is particularly suitable for the situation that the boiler installing place in an independent building is small.

Description

Heat-conducting vertical heating boiler

The utility model belongs to the boiler technology field, the vertical heating boiler of a kind of specifically heat conduction.

The heat exchange mode of boiler mostly is convection current and radiation heat transfer mode in the prior art, its floor space is bigger, and it is little to exert oneself, particularly when a certain independent building need heating and do not have again enough placement boilers local time, it is little to seek a kind of floor space, and the big boiler of exerting oneself has just seemed particular importance.

The purpose of this utility model is exactly the problem that does not have enough local arrangement boiler when independent building in order to solve, and provides a kind of floor space little, the big heating boiler of exerting oneself.

The technical solution of the utility model is to realize like this.This boiler is raised fuel type under being, the boiler hot exchange is divided into two parts up and down.Upper part is the horizontal water tube that carries out heat convection with flue gas, following partly for conduction and radiation heat transfer partial structure as shown in drawings, comb along the cylindrical shape shaft furnace that the boiler inner wall periphery is made up of many band steel vertical array of a usefulness, should leave 3-4 centimetre gap between the band steel, be convenient to circulation of air, it act as and makes coal and boiler inner wall one air layer be arranged to guarantee the fine burning of coal energy of ingress of air layer; Simultaneously perpendicular comb again of vertically disposed circle passed to the inwall of boiler to heat as transport element, finishes heat exchange by boiler inner wall and water.Because big many of the fire grate of the more conventional vertical boiler of grate area, so thermal capacity is big, combustion intensity is big in addition, and the unit volume calorific intensity is big.

In the bottom of boiler one coal-hatch is arranged in the utility model, by thrust piston coal is advanced in the stove with a hydraulic cylinder.In order to guarantee enough power, the height of coal column and the aspect ratio of fire grate are easy between 0.95-0.97 in the stove.

The utility model has the advantages that this boiler just can accomplish that burning fully, goes out energetically when the coal column height of guaranteeing to burn during at the height that requires, the metal material of use is less.Compare with other vertical boiler of same caloric value, the boiler floor space among the present invention is little, in light weight, especially is adapted to independent building, the less situation of boiler room area.

Fig. 2 is the A-A cross section view of Fig. 1

1 outlet pipe, 2 impact tubes, 3 horizontal water tubes, 4 boiler jackets, 5 fire doors, 6 stove inwalls, 7 shaft furnaces comb, 8 furnace bottom inner casings, 9 coal inleting channels, 10 push away coal piston, 11 oil hydraulic cylinders, 12 water inlet pipes, 13 smoke pipes, 14 coal-hatches among the figure.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further, the superstructure of boiler can adopt the structure of common vertical boiler in the utility model.Emphasis promptly conducts the heat exchange element shaft furnace combs in the lower portion.Shaft furnace among the present invention is combed and is made with band steel, and every band steel welds together by the stove inwall, and the lower end of band steel and boiler bottom inner casing weld together, between the band steel between the road distance serve as easy with 3-4 centimetre.During as the need coal, can place coal-hatch to be in coal to push away the effect of coal piston breeching to be pressed in the stove with oil cylinder.In order to guarantee enough heat exchange areas, the aspect ratio that the height of coal column and shaft furnace are combed should be between 0.95--0.97.

Claims

1, the vertical heating boiler of a kind of heat conduction, by shell, inwall, water inlet pipe, outlet pipe, smoke pipe, horizontal water tube, impact tube, fire door, coal-hatch, furnace bottom inner casing, push away the coal piston, oil hydraulic cylinder constitutes, and it is characterized in that having one to comb along the peripheral vertically disposed shaft furnace of boiler inner wall.

2, the heating boiler of stating as claim 1 is characterized in that comb available band steel of shaft furnace constitutes.

3, heating boiler as claimed in claim 1 or 2 is characterized in that forming on the inwall that band steel that shaft furnace combs can be welded in boiler or on the furnace bottom inner casing.
