Because the utility model adopts the structure, the utility model is suitable for various coal kinds; the environment pollution is small; the thermal efficiency is high; water can continuously fills; boiling water can be continuously supplied; the utility model can not be operated by a special person; the utility model can realize the requirements of multiple purposes of heating, showering and water drinking.

Description

A kind of pressure-less boiler

The utility model relates to a kind of water heater, specifically plant can boiling water without interruption the smoke elimination pressure-less boiler.

At present for people's used pressure-less boiler of living, comprise various tea furnaces, its specifications and models are many, but furnace binding is nothing more than being vertical water pipe double grate back firing boiler.From the operating position of the existing type of furnace, ubiquitous following not enough: as 1. can not to adapt to multiple coal; 2. the thermal efficiency is low, and energy waste is serious; 3. easily cause atmosphere pollution; 4. can not realize supplying continuously boiling water; 5. need the special messenger to guard, labour intensity is also bigger.

The purpose of this utility model is to provide a kind of environmentally safe, and is easy to operate, and saving of work and time can automatic loading water, and boiling water without interruption adapts to the energy-efficient pressure-less boiler of each coal.

The utility model is made up of major parts such as combustion chamber, flue, shell, bells, and combustion chamber is made of combustion chamber, flue, chimney three parts again, and bell covers the flue top.It is characterized in that said combustion chamber is a turriform, the bottom is the individual layer water-cooled grate; Be provided with the drawing and pulling type smoke baffle plate between combustion chamber and the chimney; Said flue is double-deck, and outer courage is enclosed within the inner bag outside, and is higher than inner bag; The water tank that one built-in ball-cock assembly is arranged between inner bag and chimney makes the water in the inner bag keep certain water level.

This boiler is provided with economizer in the export department of chimney, the economizer water inlet links to each other with running water pipe, and delivery port links to each other with the water inlet of ball float case, between economizer and the bell gas baffle is arranged.

Said flue is an annular gap cigarette wall, links to each other with the combustion chamber down, top communicates with the sidewall of chimney by bend pipe.

The bell on pot furnace outside-lining top is mobilizable.Between furnace outside-lining and the shell, between bell and the shell heat-insulation layer is arranged all.

The utility model reasonable in design is applicable to each coals such as bituminous coal, anthracite, moulded coals.Owing to adopt single fire-grating combusting reverberate burning, thereby reduced smoke discharge amount.Adopt the interlayer flue, water-cooled grate, and on back-end surfaces, be provided with economizer again, thus improved boiler thermal output greatly; The setting of interior outer furnace and ball float case can guarantee continuous water inlet, and boiling water without interruption need not special messenger's operation; Bell is dismantled and assembled simultaneously, has made things convenient for maintenance and scale removal.

The utility model is described in further detail below in conjunction with accompanying drawing and use.

Fig. 1 is the general structure schematic diagram of the utility model partly cut-away.

This is a kind of embodiment of vertical boiler.Wherein, above being provided with the stove seat 1 of fire door 2, connect furnace internal- lining 12,8 bottoms, turriform combustion chamber are provided with water-cooled grate 4, when some stove, earlier drawing and pulling type smoke baffle plate 11 are pulled out, the door of coal filling hole 10 is closed, form and just burning form, after coal is ignited, again coal filling hole 10 is opened, close the door of seeing fiery breast hole 5 and also drawing and pulling type smoke baffle plate 11 is advanced, form the anti-burning under the common state.Coal adds from coal filling hole 10 when burning at ordinary times, and the flue gas that burning produces enters chimney 25 by flue 13, discharges out of the furnace through economizer 22.Dust stratification in the chimney 25 can fall into turriform combustion chamber 8 by pulling out drawing and pulling type smoke baffle plate 11.Running water is injected by economizer water inlet 23, flows out to ball float case 16 from economizer delivery port 21, flows into furnace internal-lining 12 by downcomer 14, is full of warm water district 26, and when reaching certain waterline, the ball-cock assembly in the ball float case 16 is closed, and stops running water and injects.Water temperature in the warm water district 26 constantly raises, water boiling back boiling water overflows into boiling water district 9 by furnace internal-lining 12 upper brims edge, warm water district 26 water levels descend, ball float case 16 water levels also descend thereupon, after dropping to certain water level, ball-cock assembly is opened water inlet, waits to rise to predetermined water level and closes automatically again, so move in circles, realized adding automatically water, supplied boiling water in 24 hours continuously.Outer courage 15 tops are the bell 17 of an activity, are provided with steam vent 24 above.Outside outer courage 15, the bell 17 one deck heat-insulation layer 18 being arranged, is shell 19 outside the heat-insulation layer 18, and sewage draining exit 3 is arranged at 26 bottoms, warm water district.Outer courage bottom is provided with thermometer 7, and the bottom is a boiling water mouth 6, and this boiling water mouth 6 is the sewage draining exit in double as boiling water district 9 also.Between economizer 22 and bell 17, gas baffle 20 is arranged.

The utility model also can be made horizontal, and can the relevant position, warm water district in boiler be provided with that two cover I type heat exchangers can be realized warming oneself, the multi-purpose requirement of having a bath, drink water.
