Description

The vertical boiler device

The utility model relates to a kind of boiler generating means of steam, and exactly, it is a kind of novel vertical boiler.

As everyone knows, the course of work of existing vertical boiler for domestic is as follows: before using stove water, close outlet valve earlier, blowoff valve, make steam pipeline unimpeded, the three-way cock of Pressure gauge pipeline is in run location, opens water intaking valve then, intake to ordinary water level, before ignition of the boiler, be 40～50mm lump coal then, on lump coal, put one deck duff water pipe furnace grate upper berth one deck granularity, on duff, put a little thin bavins at last, except that coal feed point, close all the other fire doors, after this light firewood coal is ignited, wait to burn prosperous after, the coal that contains an amount of moisture content that premixing is good is evenly spread, and general flourishing layer thickness maintains 150mm, if blocked up will leading on the lower fire grating part is flourishing; If naked light application coal occurring partly covers naked light, set up an air blast at coal feed point or furnace bottom mouth, strengthen burning velocity, the heat that coal combustion produces is by water pipe, and flue directly absorbs, flame directly discharges through chimney by anti-burning pipe, because the heat that coal combustion produces is directly absorbed by flue and water pipe, temperature is not high in the stove, and anthracite and colm do not reach ignition temperature, can not completing combustion, therefore the adaptability of original steam coal is wideless.

Because the soaring direct discharging of flue gas, smoke medicining dust-removing effect is bad, and the requirement that reach dedusting must be finished by subsidiary engine, and corresponding the doubling of whole like this boiler cost increases cost of investment.Through retrieval find domestic go back neither one at present can bituminous coal, II class anthracite, smoke discharge amount is lower than national I class district standard (GB3841-83 standard for boiler soot discharge), and can bear the vertical boiler of 0.1～0.7MPa pressure.

The purpose of this utility model designs a kind of pluralities of fuel that can burn exactly, and soot emissions are lower than national I class standard, can bear the vertical boiler of 0.1～0.7MPa.

The utility model is to realize like this, in boiler combustion device, increased a combustion chamber, the outer wall of combustion chamber is one deck phosphoric acid refractory concrete protective material layer, fixed the steel of grabbing in phosphoric acid refractory concrete layer, outside phosphoric acid refractory concrete layer, be stamped backplate under the metal, be connected with a flame holder under the metal on the backplate, have the hole around the flame holder, and be connected with pipe at the two ends of combustion chamber, be used to transmit air;

In boiler body, furnace gall head II links to each other with steel pipe, and steel pipe slightly protrudes the endmost surface of furnace gall head II inwall, be used to prevent the flame upper punch, ashes are unable to come down, and are connected with the gas baffle of a cone table on furnace gall head II, and whole flue uses round-corner transition.

Design of the present utility model selects for use Q235A or the manufacturing of 20g material to finish in strict accordance with national Ministry of Labor and Personnel " steam boiler safety and technical supervision rules ", the pressure-bearing part all adopts arc transition and planar design, the experiment proved that: it has broken the directly tradition of burning of original boiler naked light, has overcome that vertical miniature boiler combustion intensity is low, combustion instability, the thermal efficiency is low, dust removing effects is poor, the high shortcoming of coal requirement.

In addition, it is little, reasonable in design to the utlity model has overall dimensions, and compact conformation is safe and reliable, energy-efficient, smoke abatement and dust control, and thermal efficiency height, power consumption is low, characteristics such as good energy-conserving effect.Its pluralities of fuel that can burn, as other ignitable fuels such as incendivity bituminous coal, anthracite and firewoods, can adapt to the requirement of colm, soot emissions are lower than national I class standard, can bear the vertical boiler of 0.1～0.7MPa, can improve the utilization rate of coal and reach environmental requirement, have wide adaptability, performance that cost is low.

The utility model will be further described below in conjunction with accompanying drawing:

Fig. 1 is the front view of boiler body;

Fig. 2 is the vertical view of boiler body;

Fig. 3 is the section left view of boiler body;

Fig. 4 is the front view of boiler combustion device;

Fig. 5 is an A-A cross section view among Fig. 4;

Fig. 6 is the left view of boiler combustion device.

At Fig. 1--among Fig. 6,1 is base; 2 is cylindrical shell; 3 is impact tube; 4 is the stop valve base; 5 is hanger; 6 is the cylindrical shell end socket; 7 is furnace gall head I; 8 is furnace gall head II; 9 is cleaning device; 10 is steel pipe; 11 is flue; 12 is the hand hole device; 13 is the fire door circle; 14 pull for flue gas retaining; 15 is pipe; 16 is fire grate; 17 is the phosphoric acid refractory concrete; 18 for grabbing steel; 19 are following backplate; 20 is upper guard board; 21 is flame holder.

As we know from the figure: the utility model it by boiler body, the pipeline valve instrument, boiler combustion device, stove gate device, the nameplate device, compositions such as chimney device, when fuel each parts when burner burns play a role, burner is mainly by base 1, pipe 15, fire grate 16, insulation material--phosphoric acid refractory concrete 17, following stove plate 19, last stove plate 20, flame holder 21 compositions such as grade, when fuel produces heat during in the stove internal combustion, insulation can not be distributed rapidly, temperature height in the stove like this, reach anthracite or burning environment of inferior quality coal temperature, thereby make fuel complete, improve the utilization rate of coal, the wide adaptability of coal.In order to ensure flame enough oxygen combustions are arranged in the combustion chamber; the way that adopts pipe 15 and stove to communicate, flame be secondary supplement oxygen during by steady flame, and so just reaching lower fire grating 16 has enough oxygen combustions; can not sinter the hole that piece stops up fire grate 16 into, influence the completing combustion of fuel because of fuel.

Flue 11 is mainly by steel pipe 10, furnace gall head I7, furnace gall head II8, gas baffle 14 is formed, steel pipe is generally 12～15, when fuel combustion produces heat through behind the steel pipe 10, the heat major part is absorbed by steel pipe 10 peripheral water quality, remaining heat flows into furnace gall head I7, furnace gall head II8 secondary absorbs, flue gas flows into furnace gall head I7 simultaneously, furnace gall head II8, dust is kept off back by baffle plate and falling in the furnace gall head II8 behind the process gas baffle, after boiler is flame-out, dust comes back in the stove by end socket intermediate dedicated steel pipe 10, so just reaches good dedusting effect, heat all absorbs, the requirement that the thermal efficiency is high.
