Abstract

The utility model relates to a water heater with a heat production device in heating system. A burning chamber and a water containing cavity are respectively made into an independent separate type structure, and a smoke channel is arranged between the burning chamber and the water containing cavity for connection. A smoke vent, a water outlet pipe port, and a water return pipe port are all arranged on the corresponding position of the water containing cavity. The utility model enables the operation and management of the stove to be very convenient, and the key burning operation is carried out aboveground to reduce labour intensity and save time.

Description

Atmospheric high-low separating heating stove

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

The normal pressure Natural Circulation hot water space heating boiler that extensively adopts nearly all is whole, direct-heating type structure at present, promptly comprises combustion chamber, water capacity chamber, flue and exhaust opening in a body of heater, and parts such as effluent pipe mouth, the backwater mouth of pipe concentrate within the integral body entirely.Because it does not adopt water pump and so on forced circulation device in system, during use, for guaranteeing the unimpeded of hot-fluid in the heating system, usually with boiler erection at below ground certain depth place, as about underground 1-2m.Its main weak point is: operation, management are very inconvenient, and space bit is equipped with certain limitation, the transfer of fuel, transport, stack all comparatively trouble, and process is many, and time-consuming bothersome, corresponding labour intensity is big.

The purpose of this utility model is to avoid weak point of the prior art, and a kind of normal pressure Natural Circulation separate type hot water space heating boiler product that can carry out burn operation more than ground is provided.

Can take following technical scheme to realize purpose.With the combustion chamber of boiler, the separate type of two independent parts is separately made in water capacity chamber, and the combustion chamber is placed in a high position, water capacity chamber is placed in the low level place, is connected with flue between the two; Exhaust opening, effluent pipe mouth, the backwater mouth of pipe are positioned at the corresponding site in water capacity chamber.

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

Fig. 1 is a kind of organigram of normal pressure height separate type heating stove.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the B-B cutaway view of Fig. 1.

The version of existing various heat generators can be adopted in combustion chamber 1, and shell can be die casting, steel plate welding or other form, and the burner hearth position assembles with refractory material, and effect is good.

The effect of flue 2 mainly is the calory burning that the combustion chamber produces is delivered to water capacity chamber 5, is a kind of indirect mode of heating to the water in the water capacity chamber.Should reduce combustion chamber 1,2 pairs of thermal loss on every side of flue as far as possible, take corresponding adiabatic heat-insulation measure, to improve the thermal efficiency in water capacity chamber.

Two of combustion chambers, the water capacity chamber independent structures separately are installed in not position respectively, and the combustion chamber is installed on the ground, is in a high position; Water capacity chamber is installed in underground certain depth place, and as about underground 1-1.5m, the relative combustion chamber is in low level.So just can reach burn operation on the ground, water conservancy project matter is heated in underground purpose, the corresponding circulating effect that improves normal pressure Natural Circulation hot-fluid.

In the accompanying drawing illustrated embodiment, water capacity chamber 5 is the sandwich that the tortuous gas flue 10 of symmetric double is contained at the middle part, and the upper and lower part is the thermal-arrest cavity volume 9 that is connected with sandwich respectively and is equipped with water capacity chamber 7; Effluent pipe mouth 3, exhaust opening 4 are positioned at the top of thermal-arrest cavity volume, and the backwater mouth of pipe 8 is positioned at the side-walls in water capacity chamber fully; In the combustion chamber 1 and the outside of flue 2 be provided with thermal insulating warm-keeping layer 11, and be provided with dedusting hole door 6 in bottom, water capacity chamber.

In the height separate type, because water capacity chamber is in underground, exhaust opening thereon, certainly will add chimney stack like this, utilize towering chimney to be drawn to pyrotechnics, the thermal current of combustion chamber underground, in the tortuous gas flue of symmetric double, weave, water in the sandwich before and after being in is up and down fully heated, discharge from exhaust opening, chimney at last.

The relative prior art of the utility model has following advantage:

Make operation, the management of boiler very convenient, the locus is unrestricted, and the burn operation of most critical carries out on the ground, saves time and saves trouble, and labour intensity reduces.

Claims
