Abstract

The utility model relates to a clean coal combustion water splitting energy-saving vertical normal/low pressure boiler. A plurality of double (single) bent fire pipes which are externally communicated with the fire by the barrel wall of the internal chamber of the boiler chamber are communicated with an upper chamber smoke box and a lower chamber boiler chamber which are spaced by the internal baffle of the boiler chamber, and the steam which can guide the rib strip and the rib groove inversely and downwards flow can conduct the water splitting, the combustion supporting, and the clean burning of the gas. The effects of the super-efficient energy saving and environmental protection are generated, and the fabrication cost and the operation cost are totally lower than the existing similar boiler. The utility model provides a perfect and renewal solution for the global vertical boiler and the hand firing boiler is provided; the wind coefficient is small than '1', the exhaust concentration of the NOx is close to 0, and the coal is saved for about 20%.

Description

Energy-conservation vertical normal, the low-pressure boiler of a kind of clean combustion of coal water-splitting

The utility model relates to energy-conservation vertical normal, the low-pressure boiler technology of a kind of clean combustion of coal water-splitting, and especially single, double curved fire tube tube bank and inboard wall of burner hearth holder bar pipe are passed and revolved fire-resistant rib, are provided with steam and return the boiler that steam pipe is realized the energy-conserving and environment-protective of the super effect of water-splitting.

At present, known normal, low pressure vertical fire coal boiler is hand and burns, and the handwarmer fire coal can't clean, usually be that black smoke is billowing, the cinder phosphorus content is very high, causes the key city, various places not having to ban coal-burning boiler under the environment protection treating effect without exception, does not almost make an exception in the whole nation.

The purpose of this utility model is: by the further application of my " 011187860 " number patent disclosure principle, on the experiential basis of the successful operation of the clean coal fired boiler of horizontal water-splitting, carry out clean combustion of coal and the water-splitting technology is carried out specific design at vertical boiler, realize the super effect energy-conserving and environment-protective of vertical fire tube boiler.

The purpose of this utility model is achieved in that whenever opens two mouthfuls and wear water-cooled layer and establish two (list) and bend fire tube in the plurality of warp threads proximal end of deepening inner bag bucket wall by this type of conventional vertical shell boiler, transverse presentation horizontal dividing plate in the courage burner hearth (makes it to being burner hearth under the smoke box under the vicinity of upper orifice again, only pass water-cooled layer and communicate by lower nozzle on two curved fire tubes, or by lower nozzle communications and liaison smoke box and burner hearth under the lower perforated plate of single curved fire tube); Burner hearth perisporium under the dividing plate beginning is established some holder bar pipe steeply inclined pipes by bottom lower nozzle neighbour, pipe on corresponding spiral welding fixed in sheet and smear, adorn fire-resistant coagulation or the refractory brick rib admittedly, and the flat costal groove face of making vertical courage wall under the bar is socialized to pass and is established; The burner hearth rectum is logical to be divided into funnel slag thorax wall formation self-heating in the tube of getting a foothold and makes meta slag thorax in the wind chamber, thorax is gone to the bottom and is established the slag comb, the then corresponding smoke box in system front portion is established out the cleaning door door, and burner hearth top thorax is opened steam and returned steam pipe and wealthy mouthful of door of coal, and thorax is discharged the cinder notch door from the slag thorax.So execute, full coal (piece in this New-type boiler burner hearth, the type shape) burning is normal, must be that the wealthy mouthful door of coal is opened the air blast of the combustion of the temperature automatically controlled department of standard (or by) and given wind, wind (with returning stove steam) only through each costal groove rotating contrary combustion-supporting down (combustion not to the greatest extent it " cigarette " " steam " hold inferior self gasification " potential energy " of warm condition in superelevation again and rise and pass relatively that following wind is contrary to offset along speed or high power stagnated under idle delaying, the time limit of time-delay after-flame substantially exceeds then that this cigarette is plain to become the fiery limit consuming time with the hydrone hydrogen-oxygen in its ditch) promptly gas promptly fire, fire stream also is threaded onto some costal grooves (the folded system's negative pressure that only is subjected to of turbulence strand designs priming) downwards, and the lower nozzle that continued is upwards incorporated the smoke box on the flue top spacer into along two (list) curved fire tube again and discharged the cigarette neck and go into the colourless waste gas of the non-dew point cigarette of chimney temperature discharge.According to me already via the combustion-supporting boiler fired coal evidence of water-splitting of national level test, this novel clean combustion of coal becomes the cleaningization of the combustion-supporting process of hydrocarbon reorganization of fire with the logical stove crack water to generate hydrogen and oxygen of steam, realize boiler give the wind coefficient much smaller than 1 and the NOx discharging to approximate 0 compound burning technology be the super effect energy-conserving and environment-protective in the leading whole world, its energy-conservation about 20% (and the cost cost all are lower than conventional similar handwarmer with operating cost) that are about, matching in excellence or beauty in existing gas turbine of dust concentration and lingemann blackness index is clear ahead.

Owing to adopted such scheme, these novel clean combustion of coal and air-breathing super effect energy-conserving and environment-protective of a large amount of replacements of water-splitting that realized that present domestic and international various hand-fired boilers all can not be realized, simultaneously, cost cost, the operating cost of boiler have correspondingly been reduced again, take charge of great technological break-throughs such as combustion, thorough burning much smaller than 1 with accurate temperature automatically controlled (joining vapour) with having added, have world-leading meaning to the wind coefficient.

The utility model is described in further detail below in conjunction with Figure of description.
