Description

Heating furnace

Technical field

The utility model relates to a kind of heat-exchange system, especially relates to the heating furnace in a kind of heat-exchange system.

Background technology

In the prior art as the heating furnace in the heating system, as shown in Figure 1, its basic structure all partly is made up of combustion chamber 1, furnace chamber 2, heat-insulation layer 7 etc., fuel burns in combustion chamber 1, the heat that produces can then import the fluid heating that flows into through fluid intake 8 in the furnace chamber 2 in the heating furnace heat exchanger in addition by fluid issuing 9 and carry out heat exchange.Fluid is generally water or gas.The flue gas that fuel combustion produced in the combustion chamber 1 directly is discharged to the heating furnace outside by chimney 5 flues such as grade.Because furnace chamber 2 is located at the outside of combustion chamber 1 usually, volume is bigger, slower by the speed that the fuel combustion in the combustion chamber 1 is heated, and the combustion chamber 1 interior high-temperature gas that produces is directly discharged by chimney 5 simultaneously, a large amount of heat energy is not by the absorption of fluids in the furnace chamber 2, therefore exist heat exchange effect poor in the heating furnace of prior art, the problem that energy waste is bigger.

The utility model content

The purpose of this utility model provides a kind of heating furnace, and this heating furnace can obviously improve the firing rate to furnace chamber, and heat exchange effect is good, and energy resource consumption is very low.

For this reason, the utility model provides a kind of heating furnace, has the combustion chamber, is positioned at the furnace chamber in the combustion chamber outside, the chimney that communicates with the combustion chamber, feeds the fluid intake of the fluid that can carry out heat exchange and with the fluid issuing of fluid to the outside derivation of heating furnace to described furnace chamber; Also have the accumulation of heat chamber that surrounds described furnace chamber to small part in the outside of furnace chamber, described accumulation of heat chamber communicates with the combustion chamber by heat pipe.

Because accumulation of heat chamber in the sealing of the arranged outside of furnace chamber, and this accumulation of heat chamber communicates with the combustion chamber, therefore when fuel combustion, the heat energy that is produced can directly enter the accumulation of heat chamber, also just can heat once more furnace chamber from the outside of furnace chamber, promptly furnace chamber can be subjected to heating when side combusion chamber is with its accumulation of heat chamber, outside in it.By this scheme as can be seen, though the accumulation of heat chamber heating furnace outside relatively is airtight, but communicate with the combustion chamber by heat pipe, be equivalent to the covert combustion chamber is become greatly, the element that also can be regarded as to the furnace chamber heating is to have increased a heating element heater except the combustion chamber again, and the chamber of accumulation of heat simultaneously also can be a warm keeping element for furnace chamber.Therefore the rate of rise in temperature in the furnace chamber can obviously be accelerated, thereby the heat exchange efficiency that can realize convection cell improves, and further saves the energy.

According on the other hand of the present utility model, on the basis of technique scheme, in described accumulation of heat chamber, economizer bank is set again, in this economizer bank, be filled with the fluid that can carry out heat exchange, described economizer bank has the arrival end and the port of export.Because the temperature in the accumulation of heat chamber is higher, and economizer bank is set therein, then can realize the multiple heating approach of multiple fluid.

If the outside that the arrival end and the port of export of described economizer bank are located at the accumulation of heat chamber, described fluid intake and fluid issuing are directly communicated with described furnace chamber, then can realize in the accumulation of heat chamber and furnace chamber in heating two kinds of fluids the time, the temperature interior owing to accumulation of heat chamber and furnace chamber is different, therefore the fluid temperature (F.T.) that flows out from economizer bank and furnace chamber is different, can chummery or space not heat respectively requiring heating temperature, thereby realize the reasonable exchange of heat.

If described economizer bank is communicated with described furnace chamber, described fluid intake is linked to each other with the arrival end of described economizer bank, the port of export of described economizer bank directly communicates with furnace chamber.Then the flow path of fluid be earlier through fluid intake outside heating furnace the side inflow economizer bank, flow into furnace chamber again, flow out heating furnace from furnace chamber through fluid issuing at last.Like this, fluid can be heated in the accumulation of heat chamber before entering furnace chamber in advance, enter furnace chamber subsequently after programming rate faster, thereby can further improve heat exchange efficiency and save the energy.

The described fluid that uses in such scheme can be air or water, and particularly for using air, its suffered restrictive condition is few, easy to implement, is specially adapted to heatings such as industry, civilian and field work.

The specific embodiment

Below in conjunction with accompanying drawing, specify embodiment of the present utility model:

Embodiment one

As shown in Figure 2, it illustrates a specific embodiment of heating furnace of the present utility model, and this body of heater roughly is divided into three-decker from the inside to the outside, and innermost layer is combustion chamber 1, and the intermediate layer is a furnace chamber 2, and outer is accumulation of heat chamber 4.Outer surface in accumulation of heat chamber 4 is provided with heat-insulation layer 7, and the body of heater below is provided with base 10.Certainly, owing to be subjected to condition restriction, the position of combustion chamber 1 also can be below furnace chamber 2, as long as can directly heat furnace chamber 2.

Combustion chamber 1 has parts such as fire door 11, grate, and fuel burns in combustion chamber 1.

1 the outside is a furnace chamber 2 in the combustion chamber, and combustion chamber 1 does not communicate with furnace chamber 2 these two cavitys but be relatively independent, thereby but two tight contacts of cavitys can pass to furnace chamber 2 fast with the heat that is produced in combustion chamber 1.The bottom of furnace chamber 2 is provided with fluid intake 8 and fluid issuing 9.Fluid such as water or air can flow in the furnace chambers 2 by fluid intake 8, flow out from fluid issuing 9 after absorbing heat so that with heating furnace beyond the space of required heating in heat exchanger link to each other and carry out heat exchange.

Arranged outside at furnace chamber 2 has the accumulation of heat chamber 4 that surrounds furnace chamber 2 to small part.The same with the relation of combustion chamber 1 and furnace chamber 2, accumulation of heat chamber 4 also is not communicate and relatively independent with furnace chamber 2 these two cavitys, and two cavitys also are closely adjacent simultaneously.Accumulation of heat chamber 4 can surround parts such as the top of furnace chamber 2 and sidepiece, certainly, and also can be with furnace chamber 2 whole its inside that are enclosed in.

Combustion chamber 1 is the same with prior art, also be connected with chimney 5 so that the flue gas that is produced is discharged, but combustion chamber 1 also communicates with accumulation of heat chamber 4 by one or more heat pipe 3 simultaneously.As seen in Figure 1, accumulation of heat chamber 4 be one closely around the cavity of furnace chamber 2, this cavity does not communicate with extraneous or other any cavity, therefore the cavity that can be referred to as to seal except with combustion chamber 1 communicates.But the sealing that this place claims not is the sealing on the absolute sense, if but hole appears in the somewhere in this accumulation of heat chamber 4 leaks, can influence the heating or the insulation effect of the 4 pairs of furnace chambers 2 in accumulation of heat chamber, only be that effect can descend to some extent.About the mode that combustion chamber 1 and accumulation of heat chamber 4 directly communicate by heat pipe 3, can be referring to Figure 4 and 5.

Shown in Figure 4 and 5, combustion chamber 1 is a square cavity substantially, is provided with a chimney 5 and Duo Gen heat pipe 3 above this cavity, and chimney 5 directly links to each other with atmosphere outside, and heat pipe 3 and accumulation of heat chamber 4 are to being communicated with.Heat pipe 3 direct spaces are the space of furnace chamber 2.

The flue gas that produces when fuel burns in combustion chamber 1 flows directly in the atmosphere outside by chimney 5, and heat energy then can enter in the accumulation of heat chamber 4 by heat pipe 3.Though accumulation of heat chamber 4 seals, as if can not produce flowing of fluid on the surface, but in fact, because gas temperature will be lower than combustion chamber temperature in the accumulation of heat chamber 4, high temperature heat in the combustion chamber can become kinetic energy and rush in accumulation of heat chamber 4, and the air in the accumulation of heat chamber is directly heated.So, when fuel just takes fire, accumulation of heat chamber 4 is heated up the fastest, it can heat from the outside furnace chamber 2, and the combustion chamber can be heated from the inside or the bottom of furnace chamber 2, when full combustion of fuel, 4 in accumulation of heat chamber also can be incubated furnace chamber 2, so enter the heating that obtains that fluids in the furnace chamber 2 can be very fast.

Having under the situation of safeguard procedures, also can not add heat-insulation layer 7, directly to the heating of needed space.

Embodiment two

As shown in Figure 3, it illustrates another specific embodiment of heating furnace of the present utility model, and is the same with embodiment one, and this body of heater also roughly is divided into three-decker from the inside to the outside, and innermost layer is combustion chamber 1, and the intermediate layer is a furnace chamber 2, and outer is accumulation of heat chamber 4.Outer surface in accumulation of heat chamber 4 is provided with heat-insulation layer 7, and the body of heater below is provided with base 10.Certainly, the position of combustion chamber 1 also can be below furnace chamber 2, as long as can directly heat furnace chamber 2.

Different with embodiment one is also to be provided with the economizer bank 6 that inside charges into fluid in accumulation of heat chamber 4.Described economizer bank 6 has the arrival end 12 and the port of export 13.The port of export 13 of described economizer bank 6 directly communicates with described furnace chamber 2, and described fluid intake 8 is arranged at arrival end 12 places of described economizer bank 6, and described fluid issuing 9 directly communicates with furnace chamber 2.

For the heating or the heating system that with gas are fluid, because require fluid to have certain flowing velocity,, improve temperature as much as possible, so that provide heat for the space of required heating or heat supply so require fluid in the set time of heating furnace of flowing through.In the present embodiment, shown in the arrow among Fig. 2, fluids such as water or air earlier through fluid intake 8 from heating furnace outside side inflow economizer bank 6, flow into furnace chamber 2 again, at last from furnace chamber 2 through fluid issuing 9 outflow heating furnaces.Fluid is heated in accumulation of heat chamber 4 before entering furnace chamber 2 at first in advance, entering furnace chamber 2 its temperature of back is subsequently further promoted, therefore can be implemented in mobile fluid can be heated respectively in accumulation of heat chamber 4 and furnace chamber 2, so also just further improved heat exchange efficiency.

For the economizer bank 6 that is arranged in the accumulation of heat chamber 4, only be a single tube schematically to be shown in the accompanying drawing as economizer bank, but can also have other a lot of embodiments, as economizer bank 6 is arranged to box-type, it is the shape that the many bodys that are set up in parallel surround casing, this casing have inlet as with the link of fluid intake 8, and fluid just flows along with the body demultiplexing that is set up in parallel after entering inlet, and then more be heated simultaneously fully, then enter in the furnace chamber 2 by an outlet or a plurality of outlet.This mode can further make fluid carry out preheating in accumulation of heat chamber 4, thereby improves the thermal efficiency.

Embodiment three

Because in some cases, different rooms or space require inner temperature of room will reach very high as some room, and some room require inner temperature of room lower to the requirement difference of heating or heating, so for same heating furnace, the fluid that need flow out in it has various temperature for well.

And present embodiment addresses that need and provide.As shown in Figure 6, the same with two with embodiment one, this body of heater also roughly is divided into three-decker from the inside to the outside, and innermost layer is combustion chamber 1, and the intermediate layer is a furnace chamber 2, and outer is accumulation of heat chamber 4.Outer surface in accumulation of heat chamber 4 is provided with heat-insulation layer 7, and the body of heater below is provided with base 10.Certainly, the position of combustion chamber 1 also can be below furnace chamber 2, as long as can directly heat furnace chamber 2.

Different with embodiment two is, the inside that is provided with in accumulation of heat chamber 4 charges into the arrival end 12 of economizer bank 6 of fluid and the outside that the port of export 13 is located at heating furnace.And fluid intake 8 and fluid issuing 9 directly communicate with described furnace chamber 2

Because the temperature in the accumulation of heat chamber 4 will be lower than the temperature in the furnace chamber 2, so the temperature of the fluid that flows out through the port of export 13 will be lower than the temperature of the fluid that flows out through fluid issuing 9.So can realize the multiple heating approach of multiple fluid.

Describe the utility model in detail by above embodiment, but the utility model is not limited to this.Those skilled in the art only otherwise exceed spirit of the present utility model and design can do various forms of changes, and these changes all belong to category of the present utility model.
