Description
Technical field: what the present invention relates to is heating boiler, and what be specifically related to is superconduction negative vacuum phase transformation boiler.
Background technology: the boiler that uses roughly has two kinds at present, and a kind of is the boiler that hot water is circulated by the furnace wall, and the furnace wall of this boiler is the intermediate water cell structure, and flue gas conducts heat to the water in the furnace wall.Most civil boiler all adopts this boiler, but the consumption of this boiler energy is bigger, and the thermal efficiency is low, from the flue dust that chimney is discharged, major polluting atmosphere environment; Another kind is the boiler that hot water is circulated by furnace wall and flue, the flue of this boiler communicates with the furnace wall, cavity between furnace wall and the flue is a flue, vacuum heat-conduction pipe upper end is passed flue and is fixedly installed togather with flue, utilize the vacuum heat-conduction pipe under the less temperature difference, to transmit the heat transfer property of bigger heat, the heat that makes full use of the flue gas in the flue conducts heat to the water in the flue, and heat is fully used, and reduces thermal losses.But the furnace wall of above two kinds of boilers is run through whole body of heater from top to bottom, the water inlet of boiler is opened on the furnace wall of lower furnace portion, the coolant-temperature gage that fills in the furnace wall around the burner hearth is low, burner hearth is in the low temperature environment, has the low problem of fuel combustion temperature, this has influenced burning of coal in the burner hearth, coal can not fully burn, heating efficiency is low, wastes energy, and the flue dust major polluting atmosphere environment that does not fully burn and form.
Summary of the invention: the purpose of this invention is to provide a kind of superconduction negative vacuum phase transformation boiler, this boiler can solve former in the low problem of boiler furnace fuel combustion temperature, improves the thermal efficiency of boiler.
The present invention is achieved in that this superconduction negative vacuum phase transformation boiler comprises body of heater, burner hearth, furnace wall, flue, vacuum heat-conduction pipe, vacuum heat-conduction chamber, the furnace wall is the intermediate water cell structure, flue communicates with the furnace wall, water circulates in furnace wall, flue, and vacuum heat-conduction pipe upper end is passed flue and is fixedly installed togather with flue; The vacuum heat-conduction chamber is fixed as one in the furnace wall of its top of insertion, upper end, vacuum heat-conduction chamber and with the furnace wall around around the burner hearth.
Flue in the such scheme comprises annular flue and circular flue, and annular flue and circular flue are arranged alternately in the body of heater; The centre bore of annular flue is a flue, and the height of annular flue and intersection, furnace wall is greater than the height of central hole.
Further scheme is upper end, a vacuum heat-conduction chamber fixed installation vacuum heat-conduction pipe, and insert in the vacuum heat-conduction chamber vacuum heat-conduction pipe lower end, and the flue of burner hearth top is annular flue, and vacuum heat-conduction pipe upper end is immersed in the annular flue.
Beneficial effect: 1, vacuum heat-conduction of the present invention chamber is around around the burner hearth, be fixed as one in the furnace wall of its top of insertion, upper end, vacuum heat-conduction chamber and with the furnace wall, owing to can vaporize behind the heat of the absorption of the high-termal conductivity heat transfer medium in vacuum heat-conduction chamber burner hearth, the steam that is heated rises to the top in vacuum heat-conduction chamber, liquefied by the water cooling in the furnace wall, discharge heat, make the temperature in vacuum heat-conduction chamber very high, like this, burner hearth is in the hot environment, fuel in the burner hearth is able to abundant burning, the heating efficiency height has improved the thermal efficiency of boiler, simultaneously, because full combustion of fuel, the smoke contamination that effluxes is little.
2, because annular flue and circular flue are arranged alternately in the body of heater, the flue of formation is the cucurbit shape of decontroling again after the continuous contraction, has prolonged the time that flue gas rises in body of heater, has improved the utilization rate of flue gas.
3, because upper end, vacuum heat-conduction chamber fixed installation vacuum heat-conduction pipe, insert in the vacuum heat-conduction chamber vacuum heat-conduction pipe lower end, the flue of burner hearth top is annular flue, vacuum heat-conduction pipe upper end is immersed in the annular flue, can utilize the vacuum heat-conduction pipe that the heat in vacuum heat-conduction chamber is conducted better in the water in the annular flue, enlarge heat transfer area.
