Abstract

The utility model relates to an energy-saving normal pressure boiler, belonging to a household heating furnace. Although the currently used heating furnace has a simple structure and low cost, the heating furnace still has low thermal efficiency and huge coal consumption, and is not propitious to environmental protection. In order to overcome the disadvantages, the utility model provides the following technical proposal: the front part of the energy-saving normal pressure boiler is a furnace body, while the back part is a water pipe-flue combined case; the external walls and the adjacent upper parts of both parts are wrapped with a water jacket; the inside of a hearth is provided with an internal horseshoe-shaped water jacket and an external horseshoe-shaped water jacket which are sleeved with each other; the inside of the water pipe-flue combined case is provided with a plurality of vertical water pipes and a plurality of transverse water pipes of a certain degree of inclination; moreover, all water pipes are communicated with the water jackets. The energy-saving normal pressure boiler has the advantages of a big heating area, small coal consumption, 92 percent thermal efficiency, fast thermal circulation speed, fast increasing room temperature and low heating cost.

Description

A kind of power-saving normal-pressure boiler

Technical field

The utility model relates to the heat energy apparatus field, especially the domestic heating stove.

Background technology

Take central heating in the city at present, remain every family in rural area and outlying district and disperse heating separately, for the stove that disperses heating, generally less, equipment is simple, cost is low, has caused the thermal efficiency low, coal consumption is big, has not only wasted coal resources, also causes the pollution of environment.So people are not only simple in structure in research, the low and low coal consumption of cost, the stove that the thermal efficiency is high, we have just carried out useful exploration under such technical background.

Summary of the invention

The purpose of this utility model is for providing a kind of simple in structure, thermal efficiency height, the power-saving normal-pressure boiler that coal consumption is few.

Realize that foregoing invention purpose technical scheme is as follows:

A kind of power-saving normal-pressure boiler, form by the body of heater of front portion and the water pipe flue combination box two parts at rear portion, top between two parts outer wall and adjacent two parts is surrounded by the outer wall water jacket of connection, bottom between two parts is a flue, in body of heater lower right side and bottom, water pipe flue combination box left side water inlet is housed respectively, in water pipe flue combination box top left, delivery port respectively is equipped with at right two ends, water inlet and delivery port are communicated with the outer wall water jacket, at the body of heater top bell is housed, has water jacket on the bell, the water inlet pipe of bell water jacket is connected with a water inlet, the outlet water pipe of bell water jacket is connected with a delivery port, in above inner of the boiler chamber is combed, being equipped with shape of a hoof water jacket with outside shape of a hoof water jacket, interior shape of a hoof water jacket overlaps shape of a hoof water jacket inboard outside, in, outer shape of a hoof water jacket is by connecting cross current, outer shape of a hoof water jacket is communicated with the outer wall water jacket by tube connector, two groups of water pipes that tilt in length and breadth are housed in the water pipe flue combination box, every group of water pipe formed by many, the water pipe two ends are communicated with the outer wall water jacket, bottom surface at burner hearth has slag notch, have ash hole in combination bottom, water tank side, at ash hole the ash discharge flap is housed, have outlet flue in the combination water box top, chimney is housed on the outlet flue.

The angle of inclination that is contained in interior vertical water pipe of water pipe flue combination box and horizontal water pipe is 10 °--20 °, caliber is 40-80mm, and tube pitch is 40-80mm.Distance between interior shape of a hoof water jacket and outer shape of a hoof water jacket is 30-50mm, and outer shape of a hoof water jacket and internal protecting wall spacing are 30-50mm, and the thickness of inside and outside shape of a hoof water jacket is 30-50mm.The thickness of outer wall water jacket is 20-40mm.

The utility model two water inlet pipes when work are connected with the water source, and two delivery ports connect heating system respectively, and fire door, ash discharge flap cover, and the slag notch uncovered is the outlet of cinder, also is the import of air.At the outer wall water jacket, in, outer shape of a hoof water jacket, the vertical water pipe of each root in bell water jacket and the water pipe flue combination box, laterally all be full of the water that needs heating in the water pipe, enlarged hot water cyclesystem, the water that is in the burner hearth position just flows after coal directly burns heating automatically, heated liter waterborne, enter the outer wall water jacket through connecting water pipe, vertical water pipe in water pipe flue combination box and laterally water pipe again, heated by flue gas, after delivery port flow out, cooling turns cold gradually after the heating system heat radiation, flow back to again in the boiler, supplementing water also constantly heads in the body of heater simultaneously, and the water after being heated once more constantly flows to heating system again, so constantly circulation is to indoor heating.

The utlity model has following beneficial effect:

1. heating surface area is big, has absorbed the heat of flame and the heat in the flue gas fully, has reduced to extraradial heat energy, has saved coal resources, and boiler efficiency reaches 92%, can realize per kilogram standard anthracite, makes 6 meters ²Keep 18-22 ℃ in 24 hours in the room, save 60% fire coal than common normal pressure soil boiler.

2. most of pipeline has the angle of inclination, and most of outer wall water jacket is vertically upward, so resistance to water-flow is little, flow velocity is fast, and the temperature of water outlet and return water temperature difference are less than 20 ℃, and thermal cycle speed is fast, and room temperature rises fast.

3. because coal consumption is few, saved heat cost.
