Description

High performance energy-saving smokeless boiler

The utility model belongs to heating installation.

Existing coal fired boiler general over-emitting black exhaust all under the situation of no deduster.And the thermal efficiency is relatively low again generally can only reach about 60%.

The purpose of this utility model is that development a kind ofly need not add deduster, is the fuel boiler of over-emitting black exhaust not again with the coal, and the thermal efficiency of this boiler is very high again, should reach more than 90%.

The utility model is by housing, intercalated water sleeve, aqueduct, fire grate, after burner, chimney are formed all around.It is characterized in that being with the column sleeve water pipe in the outside of fire grate, the column sleeve water pipe is connected with intercalated water sleeve all around.This interlayer water pipe can make full use of the heat that fire grate absorbs.After burner by heat absorption head, lead smoke pipe, second-time burning pipe, water isolation strip, secondary combustion chamber and form.Heat absorption head is fixed on the lower end of second-time burning pipe, and is among the fire coal, leads the bottom that smoke pipe is enclosed within the second-time burning tube outside, but be in the heat absorption head above, the open end of leading smoke pipe is in the top.Be on the bottom of leading the second-time burning pipe in the smoke pipe and have into mouth.The water isolation strip is fixed on the upper end in the housing, and the water isolation strip is connected with water jacket, and the water isolation strip is passed on the top of second-time burning pipe, and it is indoor that the upper open end of second-time burning pipe is in second-time burning.Chimney is connected with the top of housing by flange.Water jacket in the lower end of two aqueducts and the housing is connected, and its upper end is connected with water jacket outside the chimney, and the centre of aqueduct is connected by flange.The water jacket of chimney outside is connected with intercalated water sleeve around the boiler.

The utility model is not installed deduster and is yet over-emitting black exhaust not under the situation of fuel with the coal, sufficient combustion, and the thermal efficiency can reach 95%.And, just can supply five floor height by self pressure hot water without water pump, motor, saved electric energy, again noiseless.In stove, especially not slagging scorification in the chimney, NO ₁And NO ₂Discharge capacity compare with existing boiler and can reduce by 60%.

Fig. 1 is the integrally-built main cutaway view of the utility model, and Fig. 2 is the A-A cutaway view of Fig. 1.

Embodiment one: present embodiment is by housing 1, intercalated water sleeve 2, fire grate 3, aqueduct 4, chimney 5, after burner are formed all around.The outside of every muscle of fire grate 3 all is with column sleeve water pipe 6, and column sleeve water pipe 6 is connected with intercalated water sleeve 2 all around.After burner by heat absorption 7, lead smoke pipe 8, second-time burning pipe 9, water isolation strip 10, secondary combustion chamber 11 and form.Heat absorption 7 is fixed on the lower end of second-time burning pipe 9, and is among coal-fired 21.Lead smoke pipe 8 and be enclosed within the bottom of second-time burning pipe 9 outsides, but be in heat absorption 7 above, the openend 12 of leading smoke pipe 8 is in its upper end.Be in and have a plurality of mouths 13 that advance on the lower periphery of leading the second-time burning pipe 9 in the smoke pipe 8.Water isolation strip 10 is fixed on the upper end in the housing 1, and water isolation strip 10 is connected with water jacket 2.Water is passed every being with 10 in the top of second-time burning pipe 9, and its openend 14 is in the secondary combustion chamber 11.Chimney 5 is connected by the top of flange 15 with housing 1.Water jacket 2 in the lower end of two aqueducts 4 and the housing is connected, and its upper end is connected with the water jacket 16 of chimney outside, and the water jacket 16 of chimney outside and boiler intercalated water sleeve 2 all around are connected.The upper end of water jacket 16 is provided with delivery port 17, and the centre of aqueduct 4 is connected by flange 18.On the front of housing 1 fire grate 3, be provided with fire door 19, below housing 1 back fire grate 3, be provided with return pipe 20.Cigarette that produces after the primary combustion and unburnt granular fuel are subjected to stopping of water isolation strip 10 in rising, and then return downwards from the openend 12 of leading smoke pipe 8, the mouth 13 that advances from second-time burning pipe 9 enters second-time burning pipe 9 again, and be discharged into and carry out second-time burning in the secondary combustion chamber 11 from its outlet 14, the heat energy that heat energy that flue dust carries during this and second-time burning produce is fully absorbed by water isolation strip 10, the effect that reaches abundant burning and improve the thermal efficiency.

Embodiment two: the difference of present embodiment and embodiment one is to set up one deck fire grate 22 again in the housing 1 below fire grate 3, its objective is that the fuel that allows uncombusted and fall burns away on fire grate 22 again, reaches the purpose that makes full use of heat energy.Other composition is identical with embodiment one with annexation.
