Abstract
The utility model relates to an environment protection energy-saving boiler with no scale formation, which comprises a furnace chamber, a flue, a combustion chamber and a heat exchanger, wherein the combustion chamber and the heat exchanger are arranged in the furnace chamber. The furnace chamber is closed and evacuated; the upper part of the furnace chamber forms a negative pressure chamber; a secondary heat exchanger in the negative pressure chamber is connected with circulating water. The combustion chamber can be divided into a first combustion chamber at the lower part and a secondary combustion chamber at the neck part; the first combustion chamber has a smaller upper part and a larger lower part; the secondary combustion chamber at the neck part is provided with a gas mixer in a circumferential direction; the secondary combustion chamber is communicated with a first heat exchange body through a fire through channel and is led to the flue. The boiler keeps negative pressure running, can not be exploded forever, prevents scale formation, extends the service life of the boiler and has the advantages of sufficient combustion and no black smoke. The utility model can be widely used for heating industry and bath industry.
Description
The utility model relates to a kind of normal-pressure hot-water boiler.
The existing ubiquitous problem of normal-pressure hot-water boiler has: burn the coal over-emitting black exhaust, the severe contamination atmosphere; Move dangerous, the time have boiler explosion accident to take place; Fouling in the boiler has a strong impact on service life, and therefore, how to address these problems is the task of top priority.
The purpose of this utility model provides a kind of environmental protection and energy saving non-scaling boiler, keeps the negative pressure operation, and never blast prevents fouling, prolonged boiler service life, sufficient combustion, not over-emitting black exhaust.
The technical scheme of the utility model environmental protection and energy saving non-scaling boiler is: comprise combustion chamber, heat exchanger in burner hearth, flue and the burner hearth, it is characterized in that: the burner hearth sealing also vacuumizes, and upper furnace forms negative pressure cabin, and secondary heat exchanger wherein connects recirculated water.
Above-mentioned combustion chamber is the secondary combustion chamber of plain edition or primary zone that is divided into the bottom and neck, the shape of primary zone is up-small and down-big, the secondary combustion chamber hoop of neck is equipped with air and gas mixer, air and gas mixer is communicated with secondary air channel, secondary combustion chamber is connected with a heat exchanger by fire-through passage, and lead to flue, establish horizontal water tube in the middle of the heat exchanger.
Combustion-supporting split fire head is established at above-mentioned secondary combustion chamber top, and fire door is established in the side.
The fire grate that bottom, above-mentioned primary zone has, water seal hole and an airduct, fire door is established at the middle part, and fire door is set in the bottom.
The cross section of above-mentioned primary zone and secondary combustion chamber is circular, square or polygon.
Above-mentioned flue periphery is provided with economizer, and economizer is communicated with secondary heat exchanger recirculated water, and is communicated with the return pipe of lower end.
Positive and negative pressure table, temperature controller and gravity relief valve are established in the outer top of above-mentioned pot thorax.
This boiler can be made fire coal, combustion gas, fuel combustion type.
The course of work of the present utility model: will add water in the body of heater earlier, add to the certain altitude of normal water level mouth, stop to add water, to vacuumize in the body of heater again, beginning adds coal combustion in the primary zone, oxygen by an airduct supply, make coal at the combustion chamber destructive gasifying, the oxygen of supplying with the secondary combustion chamber blender by secondary air channel mixes with coal gas and completing combustion, the unburnt fuel gas of part is run into all after-flames of combustion-supporting split fire head on top, thermal-flame is directly entered a heat exchanger that is provided with horizontal water tube by fire-through passage, discharge by the afterbody economizer again, because water is discontented in the boiler, is again negative pressure state, the therefore heated water generation steam that in the time of 30-40 ℃, just comes to life, the aerogenesis temperature generally is controlled at about 95 ℃, in body of heater, form a low-temperature negative-pressure thus, utilize the phase-change heat transfer principle, directly the water in the secondary heat exchanger is added heat supply and use.Supply with the advanced economizer of the hot water backwater who uses, after being heated, entering the secondary heat exchanger again is heated and confesses, circulate with the need water system, if temperature reaches 95 ℃ in the stove, temperature control equipment stops the blower fan running automatically, the combustion chamber burn-out, when 80 ℃ of temperature, blower fan is opened automatically, burns away.If something unexpected happened makes when becoming malleation in the stove, when pressure reached 0.05 kilogram, gravity relief valve releasing pressure automatically reached never blast.
Advantage of the present utility model: adopt negative pressure phase-change heat transfer mode, the water in the body of heater is changed never, is not also reduced, and therefore, boiler internal is fouling never, and prolong service life greatly, reduces the business equipment investment; In addition, during boiler operatiopn, keep negative pressure state in the body of heater, can realize safety operation, never blast; Use earlier the mode of second-time burning again after the coal gasification, reach sufficient combustion, save the energy; Coal when normal combustion, the hook fire is not smoldered, and with the naked eye can't see chimney and smolders, and discharges flue dust and reaches the national requirements for environmental protection index; Can be widely used in industries such as heating, bathing, this good antiscale property method can also be used as boiler improvement and kiln transformation separately.
