Description

A kind of 30 liters of atmospheric steam boilers

Technical field

The present invention relates to a kind of 30 liters of atmospheric steam boilers.

Background technology

Existing coal-fired steam boiler mostly is the large-sized boiler that large volume, pressure surpass normal pressure; This boiler all will could use after the part monitoring is assert through national the monitoring every year; And 30 power of boosting are not assert and can be used through country's monitoring part monitoring with interior atmospheric steam boiler at one kilogram, are subjected to welcome on the market very much.Existing 30 liters of atmospheric steam boilers generally include stove seat, stove seat below ash hole, burner hearth, be installed in the burner hearth top flue, be installed in the chimney at flue middle part, its shortcoming is that (1) burner hearth is more shallow, and is coal-fired insufficient; All will join air blast during use, and cost is higher; (2) the smoke evacuation chimney is installed in the directly top of pass-out flue, boiler middle part, and its smoke pipe is longer, and its smoke pipe has taken the volume of flue on the one hand, and hot water amount and quantity of steam are reduced; Carry away certain heat energy because burning is insufficient in addition, and still have a large amount of solid dust to be discharged in the air in the cigarette, environment is had pollution; (3) fuel combustion is insufficient, and the heat energy that discharges is not fully used, and body of heater do not establish water jacket outward, perhaps only is located at the burner hearth periphery, and the stove seat is peripheral and go out the outside, coal ash chamber and do not establish water jacket, and the thermal efficiency is low.

Summary of the invention

The objective of the invention is to overcome above shortcoming, provide that a kind of cost is lower, the more significant 30 liters of atmospheric steam boilers of energy-saving effect.

Technical scheme of the present invention is: the stove seat that comprises stove outer covering, below, be located at the burner hearth in the stove seat, the flue of burner hearth top, be located at the coal filling hole between burner hearth and the flue, what be located at stove seat below goes out coal ash chamber, water inlet pipe, smoke exhaust pipe, it is characterized in that described burner hearth is the up-narrow and down-wide cone shape cavity of dark 40-60 centimetre, diameter 30-60 centimetre; Described smoke exhaust pipe is opened on a side between burner hearth and the flue, and smoke exhaust pipe length is 60-100 centimetre, and its upper end is a little more than the top of flue; Be provided with the superconduction heat-transfer pipe between flue and burner hearth, the lower end of superconduction heat-transfer pipe is lower than the minimum point of chimney opening.

At stove seat and burner hearth with go out to be provided with stove seat intercalated water sleeve between the coal ash chamber, between flue and shell, be provided with the flue intercalated water sleeve that is communicated with flue, two intercalated water sleeves are interconnected, and described water inlet pipe is located at the intercalated water sleeve below between stove seat and the ash hole.

The length of described superconduction heat-transfer pipe is 0.4 ~ 1m, and the spacing between adjacent two pipes is 5 ~ 10cm.

Be provided with cleaning door at the smoke exhaust pipe lowest part.

One side is provided with the air inlet adjustment mouth in the smoke exhaust pipe lower end.

Described water inlet pipe has manual water inlet pipe and electronic valve water inlet pipe.

The course of work: earlier by the electronic valve water inlet pipe or manually water inlet pipe in flue, add suitable quantity of water, what of the flue internal memory water yield can be gone out by the instant playback of water level meter; In burner hearth, add enough coal-fired by coal filling hole, can make through up-narrow and down-wide this special setting of burner hearth coal-fired fully contact with air and can produce powerful heat energy by concentrate firepower, the superconduction heat-transfer pipe of the high temperature of fired coal combustion generation by flue lower surface and burner hearth upper surface reaches in the flue water heated; The waste gas that has a large amount of heats that produces in the burner hearth laterally adds hot water once more through the superconduction heat-transfer pipe, discharges burner hearth by chimney again.

Advantage of the present invention: (1) burner hearth is dark, and its up-narrow and down-wide particular design can make fire coal fully contact with air, and it is more abundant to burn, and can produce powerful heat energy, so do not join air blast again, can reduce the air blast cost and reduce and take up an area of the space; (2) because the long design of burner hearth makes burning more abundant, so select 60-100 centimetre short chimney also combustion gas and flue dust efficiently for use, remedied short this defective of chimney emission difficulty, reduced the cost of smoke pipe; (3) smoke exhaust pipe is opened on the another side above the coal filling hole between burner hearth and the flue, and the waste gas that has a large amount of heats that produces in the burner hearth enters chimney from horizontal through the superconduction heat-transfer pipe; Can heat once more the superconduction heat-transfer pipe, make the utilization rate of heat energy higher, and not take the volume of flue, hot water amount and quantity of steam are increased; (4) design of the use of superconduction heat-transfer pipe and other position makes the heat energy utilization rate higher, and energy-saving effect is more remarkable.Based on above reason, though the present invention's flue internal volume has only 30L, can produce the high-temperature steam of capacity, but through testing once boiling 50kg rice of this 30 liters of atmospheric steam boilers; And volume is little, reasonable in design, and cost is low, meets low-carbon economy under the epoch, the theme of energy-conserving and environment-protective, and this 30 liters of atmospheric steam boilers shouldn't can use through country's monitoring part monitoring identification, can popularize fast and use.
