Abstract

The utility model relates to a water heater with a device for generating the caloric. A reflection sandwich structure is arranged between a furnace body and a burning chamber on the basis of a secondary burning boiler; a smoke channel is divided into a reflection smoke channel and a main smoke channel, and a water-heating boiler of three-burning under atmosphere with combustion reflex and circuitous process is formed. The utility model has the advantages of high thermal efficiency and favorable heating effect; besides, the heat energy can be fully utilized. When the utility model is provided with a water storage cavity, the structure of a heating system is simple, the installation of the utility model is convenient and timesaving, and the utility model is convenient in use.

Description

Water-heating boiler of three-burning under atmosphere

The utility model relates to a kind of water heater that heat generator is arranged.

In the boiler for warming rooms, the second-time burning hot-water heating system is arranged, they are usually by interlayer body of heater, combustion chamber, flue, exhaust opening, major part such as outlet pipe and return pipe constitutes, water in the interlayer through the combustion chamber and the effect of flue twice combustion obtain the heating, its weak point is: the thermal efficiency is low, though through twice combustion, but still have certain heat to discharge in the flue, influence heating effect from exhaust opening; When this in addition boiler uses in heating system, need usually in system, to set up water tank, promptly outside the boiler water tank is set, the one, cause complex structure.Install and take a lot of trouble, moreover can not utilize the waste heat of boiler well, equally also can cause the thermal efficiency to reduce.

The purpose of this utility model is to avoid weak point of the prior art, and provides a kind of thermal efficiency height, the second-time burning type hot water space heating boiler product that heating effect is good.

Can take following technical scheme to realize purpose.On the basis of second-time burning boiler, reflection sandwich is set between body of heater and combustion chamber, flue is separated into reflection flue and flue collector two parts, constitute three burnings of the circuitous normal pressure that carries out of combustion-gas flow reflection water-heating type boiler.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 1 is the front view of a kind of structure of three metabolic water heating boilers of normal pressure;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the left side view of Fig. 1.

The effect of reflection interlayer 3 is to make burning, high-temperature flue gas stream to be reflected, and circuitous carrying out makes full use of heat energy, and a large amount of heat energy of avoiding combustion chamber outlet flue 14, glory hole 15 etc. to locate to flow out are very fast discharges from exhaust opening 13.No matter adopt any type of furnace, outer shape is how, set up the reflection interlayer after its thermal efficiency all can obtain in various degree improvement.

The overall structure of this boiler, can only constitute, thermal-arrest cavity volume 7 also can be set on the top of each sandwich by institutes such as the furnace sandwich 1 that is interconnected, reflection interlayer 3, combustion chamber interlayer 5, flue collector 2, reflection flue 4, combustion chamber 6 and exhaust opening 13, outlet pipe 9, return pipes 10; Or take other form to constitute, this boiler can adopt various coal charges and goods thereof to act as a fuel.

In the accompanying drawing illustrated embodiment, the middle part of boiler is provided with furnace sandwich 1, reflection interlayer 3, combustion chamber interlayer 5; The watertightness thermal-arrest cavity volume 7 of the top of boiler for being connected with each sandwich, outlet pipe 9 is installed in the top of thermal-arrest cavity volume; The bottom of boiler is equipped with water capacity chamber 8 for the watertightness that is connected with each sandwich, and return pipe 10 is installed in the bottom in water capacity chamber fully; And be respectively equipped with reflection flue, flue collector dedusting hole door 11,12.Reflection interlayer 3 is separated into reflection flue 4 and flue collector 2 with flue; When burning heating in the combustion chamber 6, the effect that the heat energy that outwards flows through outlet flue 14, glory hole 15 is subjected to reflecting interlayer, circuitous carrying out in reflection flue, flue collector, a large amount of heat energy are absorbed by the water in each sandwich and the thermal-arrest cavity volume, can make the backwater that is equipped with in the water capacity chamber obtain preheating, heat simultaneously.Be equipped with water capacity chamber and can prevent boiler vaporization, the stable water supply when guaranteeing work, it can replace the water tank in the heating system, promptly saves tank parts outlet pipe, return pipe and can take the circumstances into consideration as required to accelerate.

Dedusting hole door

11,12 can be eliminated the dust foreign material in each flue easily.This overall structure result of use the best.

The relative prior art of the technical program has following advantage:

1, thermal efficiency height, heating effect are good, it through the combustion chamber, three burnings of reflection flue, flue collector, heat energy is fully utilized; Water in the standby water capacity chamber is got back in advance Heat, heat, result of use is good than other boiler, the thermal efficiency can improve about 20%.

When 2, using in heating system, simple in structure if the boiler bottom with then saving water tank for water capacity chamber, causes, installing saves time saves trouble, and uses more convenient.

3, it is suitable for middle or small (in, low-rise building) unit to use especially.

Claims

1, three metabolic water heating boilers of a kind of normal pressure, it is made up of interlayer body of heater, combustion chamber, flue, exhaust opening, outlet pipe and return pipe, it is characterized in that: also be provided with reflection sandwich 3 between body of heater and combustion chamber, it is separated into reflection flue 4 and flue collector 2 with flue.

2, boiler as claimed in claim 1 is characterized in that: it is provided with furnace sandwich 1, reflection interlayer 3, combustion chamber interlayer 5 structures at the boiler middle part; The watertightness thermal-arrest cavity volume 7 of the top of boiler for being connected with each sandwich; Outlet pipe 9 is installed in the top of thermal-arrest cavity volume; The bottom of boiler is equipped with water capacity chamber 8 for the watertightness that is connected with each sandwich, and return pipe 10 is installed in the bottom in water capacity chamber fully; And be respectively equipped with reflection flue, flue collector dedusting hole door 11,12.
