Description

Household infrared and coal gas heating boiler and fire collecting cap thereof

The utility model relates to a kind of family expenses soil heating boiler.

For solving the winter heating problem, many families and native heating installation has been installed than subsection, employed heating boiler is varied, a kind of water-jacket typ heating boiler (magnificent rich board of selling on the market, Beijing " efficient household central heating heating stove " is for example wherein arranged, the patent No. 87216128), it is economized coal with thermal efficiency Gao He and is celebrated, and is subjected to the user and welcomes.This boiler has shell and stone or metal plate for standing a stove on as a precaution against fire, in in the shell, the tubular furnace lining is equipped with in the bottom, be full of heat insulation filler between furnace lining and the housing, fire bars and the grey chamber of sealing are arranged at the bottom of furnace lining, be equipped with furnace lining is coaxial but the tubular intercalated water sleeve that internal diameter is bigger furnace lining upper end, on it, the bottom is welded with outlet pipe and return pipe respectively, so as to linking to each other with caliduct, the heat absorbing sheet of uniform some circumferentially extendings on the ring inwall in the water jacket, the inner of each heat absorbing sheet crosses a cylindric space coaxial with intercalated water sleeve at the stove center, an internal diameter and furnace lining ring-type fire-suppressing tube unanimous on the whole closely is housed in this space, its upper end is lower than intercalated water sleeve and is stamped airtight fire-suppressing cover, the lower end of fire-suppressing tube is bearing on the furnace lining upper surface and leaves certain slit, the intercalated water sleeve upper end communicates with the ring-type flue and is stamped an adjustable fire sealing cover with adjustable window, fire door is arranged on the stone or metal plate for standing a stove on as a precaution against fire as the flue loam cake and be stamped bell.

Honeycomb briquette is placed on the furnace lining internal combustion during heating, flame and thermal current are hindered by the fire-suppressing cover of fire-suppressing tube upper end, only can overflow by way of the lower end of fire-suppressing tube and the slit between the furnace lining, arrive the fire-suppressing tube top by the rising of the ring-type fire suppressing channel between fire-suppressing tube and the intercalated water sleeve, and excessive by the adjustable window on the adjustable fire sealing cover of intercalated water sleeve upper end to flue.Because concentrating near intercalated water sleeve, thermal current flows, the intercalated water sleeve inwall directly contacts with flame and thermal current, be welded with densely covered heat absorbing sheet again, endotherm area is bigger, so the thermal efficiency is higher, the heating effect is better, again owing to the window on the adjustable fire sealing cover can be adjusted at any time, with control burning of coal speed, so can save coal.Cook when heating up water, take off fire-suppressing cover, adjustable fire sealing cover and bell, put into the combustion-supporting portfire that a middle part of the side has ring flange, this flange disk cover is in intercalated water sleeve upper end, and correct under the portfire with the fire-suppressing tube upper end in connect, thereby cut off fire suppressing channel, stop heating, and flame guiding fire door.Because the fire lid is more, the exhaust gases passes complications, resistance is bigger, the coal-fired intensity of a fire is not prosperous, and the intercalated water sleeve axial dimension is less, has limited endotherm area, though many heat absorbing sheet conduction are arranged cheers, but heat-transfer capability is also limited, and the cold water of being put back by radiator is without preheating, directly enters the water jacket thermal treatment zone and near outlet pipe, leaving water temperature and circulation rate have been influenced, so heating starts slow, effect still can not be satisfactory, and especially the two-earners family has descended class, be eager to light a fire and cook, have to suspend heating, so the room temperature rising is slower, incompatible modernized fast pace life is required.

Task of the present utility model provides a kind of improved domestic heating boiler and heat-accumulating thereof, require health easy to use, start fast, flame is high, firepower is violent and adjustable, the thermal efficiency is high and economize coal, not only being suitable for cooks heats up water, more be suitable for efficient heating, and the heating of cooking is neglected neither.

Solution is such, boiler shell is made of an intercalated water sleeve, on it, the bottom is connected to outlet pipe and return pipe respectively, the water jacket lower end is equipped with fire bars and is connected with the grey chamber of a sealing, bank up a fire to overlap with a taper that has flue and join in the water jacket upper end, fire sealing cover is stamped in the set upper side of banking up a fire, it is characterized in that, in interior week of water jacket, the bottom is wrapping tightly in one, all scribble the tubular furnace lining of infrared coating on the outer wall, the interior ring that exceeds furnace lining on water jacket top installs some and interlayer water rings of being communicated with coaxial with water jacket additional, side at body of heater, fix the sealing steam water tank (can replace daily expansion tank) that an end face is higher than the caliduct top, on it, the bottom respectively is connected to the pipe of a band valve and is communicated with outlet pipe and return pipe on the water jacket respectively, and the case top also is connected to a pipe of being with valve and is contained in the fire bars crevice place jet jet pipe that can make progress and communicates.

The heat-accumulating that is exclusively used on this boiler is in the form of annular discs, and its diameter dimension is slightly less than interlayer water ring internal diameter, its lower edge place uniform some can be in order to be bearing in the supporting leg on lower floor's water ring end face.

Open the valve of three pipes on the water tank during use earlier, by the running water pipe water filling in case (air during water filling in the case can be discharged by the pipe and the jet pipe on case top) that directly is communicated with this water tank, make water be full of the interlayer water ring, water jacket and whole caliduct, but certain space (can control by the outer water level meter of case) will be left in the top of noting water tank, close the valve that is communicated with of running water valve and outlet pipe, return pipe and caliduct, the blow-on of can lighting a fire.Behind the coal ignition, the water yield in the intercalated water sleeve seldom, the very fast intensification of meeting, and carry out heat exchange separately by the water in connecting pipe and the steam water tank, make the water in the case be warming up to boiling, the steam that is produced sprays in the stove by the jet pipe at the pipe importing fire bars place on case top, red-hot coal-fired circuitously can produce water-gas to steam, and form red-hot gas burner immediately, jump on the fire sealing cover of furnace roof with certain pressure, warp is returned at the cover of being banked up a fire by taper, the combustion chamber internal combustion that water jacket and water ring are formed, because water jacket directly contacts with flame with water ring, and contact area is more much bigger than intercalated water sleeve itself, and water ring also can positively stop a part of flame, and the heat that water ring received can directly be passed to the water in the ring, the infrared coating that is coated with on the furnace lining can aggravate heat radiation, and the part intercalated water sleeve that is rolled in outside the furnace lining also can absorb heat, carries out preheating with opposed time cold water, so the thermal efficiency obviously improves.Open the valve that is communicated with of outlet pipe and return pipe and caliduct this moment, then outlet pipe will flow to radiator with boiling water, and the cold water that displacement is returned enters the water jacket bottom by return pipe, and directly conducted by furnace lining and the heat preheating of radiation is risen, also can seethe with excitement and send when being raised to the water ring place.Because the leaving water temperature height, circulation is also obviously accelerated, and room temperature also promotes rapidly, and heating area also can enlarge.If again the plate-like heat-accumulating is sent into the combustion chamber by furnace roof, with its supporting rack on lower floor's water ring end face, gas burner is hindered by heat-accumulating, be forced to scurry out by way of the crack of heat-accumulating and water jacket, the front jumps on water jacket and water ring, and along water jacket and water ring towards on crawl, thereby can further improve the thermal efficiency.When room temperature is moderate, can close the pipe valve of steam water tank upper and lower part, reduce or stop the heat exchange of water tank, then reduce or stop the steam supply of water tank, so the ingle gesture can obviously weaken,, then can be in the state of banking up a fire if close fire door again.Because during blow-on, stove fire is the low amounts of water in heating water jacket and the water tank only, thus start fast, in case water boil produce steam and be converted into coal gas after, ingle flame height, firepower are violent, keep boiling water to send, the water circulation is also accelerated always, so room temperature rises soon, can enter the state of banking up a fire very soon, can improve its fuel value after adding coal-fired circuitous steam again, so the thermal efficiency is very high, the time saving and energy saving coal of economizing again.Opening the fire sealing cover of furnace roof can cook, and heats up water, and firepower is also very capable, if want to weaken firepower,, can get instant result as long as suitably reduce the flow (but can not close) of vapor line, and can cook, warm oneself and neglect neither, the most suitable two-earners family's fast pace life is required.Burn surplus ashes and fall into the grey chamber of sealing, can be not excessive, so health again easy to use.
