Abstract

The invention belongs to a high-efficiency energy-saving constant-pressure hot-water heating boiler, and relates to a vertical-type high-efficiency energy-saving constant-pressure hot-water heating furnace which is applicable to heating for companies and residential districts in winter in the northern part of the country. A furnace outer large water jacket belongs to a flame waste-heat absorption system, one to multiple layers of endothermal annular water jackets are installed in a furnace and belongs to a high-temperature system, and heat-conducting media such as water and oil can be used for heating exchanging in a furnace jacket. Heating installation return water firstly enters the upper opening of the furnace outer waste-heat absorption large water jacket, descends slowly, absorbs flame waste heat, is conveyed out of A6, enters B1 the multiple layers of endothermal annular water jackets, and circularly absorbs heat in a circle to heat up; the water enters the second layer water jacket through a connecting pipe and circularly absorbs heat in a circle to heat up again, the water, in the similar way, circularly heats up through each layer of endothermal annular water jacket, and heating air is conveyed from a B2 outlet. One to multiple layers of endothermal annular water jackets on the upper portion of a furnace chamber exchange heat in an up-down mode surrounded by furnace fire, a flame on the multiple layers of endothermal annular water jackets exchanges heat in an up-and-down outwards-walking inward-return mode, flame outside waste heat is absorbed by the furnace outer large water jacket, fire smoke finally arrives at a chimney outlet and is discharged, and hands cannot be burned. Compared with domestic old boilers which are in use and sold in the market in the country, coal is saved by 30%. Therefore, the vertical-type high-efficiency energy-saving constant-pressure hot-water heating furnace is a new generation which has the advantages of being publicly-energy-saving, simple in manufacturing technique, convenient to install and use.

Description

The vertical high-efficiency energy-saving normal pressure hot water heating stove

1, technical field:

The invention belongs to energy-efficient class normal pressure hot water heating stove, be applicable to enterprises and institutions, residential building is adopted dim use.

Available water, other heat-conducting medium of wet goods in boiler clothing.

2, technical background:

That China every profession and trade unit, residential quarter winter heating use is small-sized vertical, the horizontal boiler structure, be project organization in the early days of foundation, because it is little to absorb area of flame, the utilization rate of coal flame only has 60-70%, due to disposable small investment, floor space is little, and is easy to install.Remain now the requisite capital equipment of some unit winter heatings.

Absorb in my newly-designed vertical high-efficiency energy-saving normal pressure hot water heating stove, stove that area of flame is large, the flame utilization rate is high, energy-efficient is the substitute products of old-fashioned boiler.

3, technology contents:,

In stove design and installation multilayer heat absorption ring-shaped water jacket, the stove periphery design has been installed the large water jacket of absorption flame waste heat, with the flame waste heat recovery, reduces the heat waste rate of flame.

4, energy-efficient being achieved in that

The backwater of heating installation is first got back to the peripheral flood cover of stove absorption waste heat suitable for reading, enter large water jacket slowly descending, absorb the waste heat of burner hearth flank fire flame, improve water temperature, water walks to A6 to B1 and enters interior stove heat absorption ring-shaped water jacket, the week heat absorption of going in ring heats up, and enters intensifications of absorbing heat again in one week of 2 layers, ring-shaped water jacket circulation through tube connector B3 again, with the intensification of every layer of heat absorption ring-shaped water jacket of similar circulation heat absorption mode approach, enter heating installation through the B2 delivery port.

5, flame heat exchange trend:

Fire is distributed in the up and down heat exchange of multilayer heat absorption ring-shaped water jacket above burner hearth, return for several times in fire is outside, up, arrives at last chimney breast and discharges, and the flame heat utilization efficiency reaches more than 95%, and the old structure boiler ratio that is using economizes on coal 30%

6, boiler for producing manufacturing:

Full stove can be used the Plate Welding manufacturing, the peripheral large water jacket of stove, and interior stove absorbs ring-shaped water jacket can weld respectively rear assembling, simple process, installation and maintenance are convenient, and the production cost is low, is a new generation of present energy savings.

Claims (3)

1. multilayer heat absorption ring-shaped water jacket has been installed in stove, has been had the area of flame of absorption large, water layer is thin, good effect of heat exchange.The superior of people do not scalded in the smokestack outlet.

Flame from the height of siege upward stroke 3-4 rice by way of repeatedly in the ring-shaped water jacket heat exchange of turning back up and down, only have a small amount of flame waste heat in the interior stove outside to be absorbed by the large water jacket in periphery.

3. set the current trend, after water covered into, absorbs interior stove outside flame waste heat from peripheral flood, water entered interior stove multi-layer high-temperature water jacket automatically, then heats up.
