Description
Technical field
The utility model is related to hot-water boiler, belongs to boiler technology field.
Background technology
Boiler is a kind of energy conversion, and the energy inputted to boiler has chemical energy, electric energy, high-temperature flue gas in fuel
The form such as heat energy, and pass through boiler conversion, outwards steam, high-temperature water or organic heat carrier of the output with certain heat energy.It is many
For thermal power station, ship, locomotive and industrial and mining enterprises.
The main operational principle of boiler is that the waste heat in the heat energy or industrial production discharged after a kind of utilization fuel combustion is passed
Pass the water in container, make water reach required for temperature or certain pressure steam heat power equipment.Boiler is in " pot " and " stove "
Two parts are carried out simultaneously, and water enters after boiler, and boiler heating surface feeds water the heat transfer of absorption in boiler circuit, makes water
The hot water or generation steam of certain temperature and pressure are heated into, application is brought out.In combustion apparatus part, fuel combustion is constantly put
Go out heat, the high-temperature flue gas produced that burns transfers heat to boiler heating surface by the propagation of heat, and self-temperature gradually drops
It is low, finally discharged by chimney.
Hot-water boiler belongs to pressure vessel, because hot-water boiler is in full water state all the time, does not set water-level gauge, still
Pressure gauge, safety valve and thermometer must be installed.The water circulating pump of hot-water boiler heating system typically selects clarified water pump, and it is to take out
The backwater of system engineering is sent to boiler, should overcome system circulation resistance, maintains boiler to have certain pressure again, it is ensured that during high temperature
Hot water is not vaporized.Hot-water boiler can supply water at low temperature, and can supplying high temperature hot water.
Traditional hot-water boiler, the heat energy of burner hearth fuel combustion is mainly absorbed and used by backhaul smoke pipe, after burning
Flue gas in burner hearth temperature highest, but residence time of the flue gas in burner hearth is very of short duration, and flue gas rapidly enters return flue,
Flue gas flow rate is fast, and heat energy can not fully be absorbed and used, and cause to eventually enter into the flue gas in chimney and also contain heat energy, cause heat
It can waste.
Utility model content
In order to solve above-mentioned problem, the utility model discloses a kind of hot-water boiler, concrete technical scheme is as follows：
Hot-water boiler, including body of heater, burner hearth and burner, the burner are placed in the outside of body of heater, and the burner hearth is placed in
In body of heater, the bocca of burner against burner hearth,

The cross section of corrugated pipes expands and reduced periodically, and it is in fire in cone shape, the burner hearth to be set at burner nozzle
The downstream of gesture is provided with return combustion chamber, and the vertical direction of the return combustion chamber is provided with rear smoke box, the relative body of heater of the rear smoke box
The other end is provided with front smoke box, is provided with backhaul smoke pipe between the front smoke box and rear smoke box, the burner by bocca to
Jet bubble reactor in burner hearth, fire smoke box after burner hearth and return combustion chamber rise into, fire becomes flue gas, and flue gas is passed through from rear smoke box
Backhaul smoke pipe enters front smoke box.
The outer surface of the cooling corrugated pipes sets several salient points.
The flue is provided with water outlet water pipe close to burner one end, and flue is provided with into Shui Shui close to one end of return combustion chamber
Pipe, the water inlet water pipe is located at the lower surface of flue, and the water outlet water pipe is located at the upper surface of flue.

Pipe, the cooling corrugated pipes are provided with out liquid water pipe close to burner one end.
The water outlet water pipe, water pipe of intaking, go out liquid water pipe and feed liquor water pipe is respectively arranged with flow valve.
The two ends of the backhaul smoke pipe are connected with front smoke box and rear smoke box respectively.
The beneficial effects of the utility model are：
The fire that burning is produced in burner is ejected into burner hearth by bocca, and fire has high heat energy, and fire is in burner hearth
Interior to be moved towards return combustion chamber, heat energy is fiery to become flue gas in burner hearth or return combustion chamber towards lost in surrounding environment, and flue gas is passing through
During backhaul smoke pipe, heat energy is absorbed by backhaul smoke pipe.
When spraying to the fire or flue gas of burner hearth through supercooling corrugated pipes from burner, the cooled corrugated pipes of partial heat are inhaled
Receive, heat energy can be absorbed quickly in burner hearth because cooling corrugated pipes are hanging, it is very fast to the cooling-down effect of fire or flue gas.Cold
But wave pipe surface is provided with salient point, can the air-flow of fire or flue gas there is reduction of speed effect.And the wave of cooling corrugated pipes shrinks
Or expansion, there is turbulent flow to the air-flow of fire or flue gas, increase streaming for fiery or flue gas, extend its residence time and walking road
Footpath.
The utility model can increase the utilization rate of combustion heat energy, fully absorb and utilize heat energy, and extension flue gas is in body of heater
Residence time, and in increase flue gas heat energy uniformity, the heat energy allowed in flue gas more rapidly, evenly can be absorbed profit
With, it is to avoid in thermal waste, the flue gas finally emitted, comprise only extremely a small amount of heat energy.
