Abstract
The present invention relates to a boiler with water pipes and fire pipes, and with flow in opposite directions, which is composed of a boiler drum, a combustion chamber and fire grates, wherein a face arch, an I type vertical arch, a II type vertical arch and a III type vertical arch; fire combustion openings are arranged on the vertical arch. The lower parts of both the I type vertical arch and the II type vertical arch are provided with the fire combustion opening, and a gap is formed between the upper part of the II type vertical arch and the top surface of the combustion chamber; the III type vertical arch is in a wall grid type or a through hole type, and is provided with the fire combustion opening in the two kinds of forms. Smoke gas is formed into an l-shaped gasification combustion form with stable combustion and quick temperature rise in the face arch area, and the radiation heat of the high temperature smoke gas is centralized to reflect on the surface layer of combustible substances, so the combustible substance is directly and instantly ignited; the temperature of the boiler hearth can be quickly enhanced to increase and improve the combustion conditions of the boiler hearth, and realize the high efficiency of the boiler. The residence time of the smoke gas in the boiler hearth can be prolonged above one time, so the present invention raises the heat efficiency and can save more than 20% of fuel than that of the boiler with the same size; the present invention decreases the ash deposition quantity by 58.3% than that of standards and creates the precedent of smoke initial discharge detection in industrial boiler industries.
Description
(1) technical field:
The present invention relates to the design and fabrication technology of fire tube boiler.
(2) background technology:
Generally the fire tube boiler of Shi Yonging is made of boiler drum, combustion chamber and fire grate, and the herringbone chimney arch is set in the combustion chamber, adopts forward and backward arch strong convection burning.Actual motion shows, the flue gas that from rear arch, sprays, its speed is not high, and flue gas stream is close to arch face, be laminar flows, can't rush in face arch and make flame be full of the face arch district, face arch district temperature is not high, causes the burner hearth performance of igniting not good, mixed performance is low, the boiler over-emitting black exhaust, soot emissions exceed standard, and have a strong impact on environmental quality.
(3) summary of the invention:
The present invention addresses the above problem emphatically, makes the boiler performance of igniting good, saves the energy, and the dust stratification amount reduces.
Technical scheme of the present invention is: be made of drum, combustion chamber and fire grate, the upright arch of face arch, I type, the upright arch of II type and the upright arch of III type are set in the combustion chamber, fire combustion mouthful is set on upright arch.The I type stands the arch bottom fiery combustion mouth, and the II type stands the arch bottom fiery combustion mouth, and the II type stands arch top and the combustion chamber end face has the space, and it is tracery wall form or through-hole type that the III type founds arch, and fiery combustion mouth is all arranged at two kinds of form bottoms.
The invention has the beneficial effects as follows: utilize the positive and negative convective principles of flue gas in the combustion chamber, to set up difform upright arch, flue gas is formed in the combustion chamber
Shape gasification, and combustion process.Flue gas has formed in the face arch district
Shape gasification, and combustion form, flameholding, heat up rapidly, what can make that the radiations heat energy of high-temperature flue gas concentrates reflexes to the combustible top layer, moment the combustible that directly ignites, when having solved Water-Fire Tube Shell Boilers igniting for many years breakthroughly and normally having moved stove, because of flue-gas temperature is low, combustible can not get a clean-burning difficult problem.Owing to adopted effective positive and negative convective burning chimney arch, high-temperature flue gas moment is flowed to the face arch district, flue gas has formed in the face arch district
Curve not only can directly ignite, and can improve the temperature of burner hearth rapidly; Increase and improved the burner hearth burning condition greatly, the upright arch that is adopted, simple in structure, the coating area is little, and the boiler radiation heating-surface improves greatly, has realized the high efficiency of boiler.Adopt positive and negative convective burning chimney arch, the holdup time of flue gas in burner hearth can prolong more than one times, improved fire box temperature, owing to substantially improved stove internal combustion condition, combustible in the flue gas is thoroughly burnt, in stove, formed splendid combustion conditions, improved the thermal efficiency, than more than 20%, embodying remarkable energy saving effect with capacity boiler fuel saving.Significantly reduced the dust stratification amount, traditional fire tube boiler shell-type boiler is because flue gas flow rate is not high, and rear arch dust stratification amount is big, has increased labour intensity, and positive and negative convective burning chimney arch is owing to adopt upright arch, and flue gas forms between arch form
In the time of the shape gasification, and combustion, the holdup time is longer, forms dust chamber between arch and the arch, falls into ash bucket with cinder after the sedimentation several times.Specified layer combusting boiler flue dust initial ejection concentration is 1600mg/m among the boiler smoke initial ejection concentration GWPB3 " emission standard of air pollutants for boilers "
3, detect through environment protection and monitoring unit, survey and be 677mg/m
3, reducing by 58.3% than standard, environment protecting is outstanding, has started the precedent that Industrial Boiler industry flue dust initial ejection detects.

Fig. 1 is a structural representation of the present invention.
Fig. 2 is the upright arch of I type side view.
Fig. 3 is the upright arch of II type side view.
Fig. 4 is the upright arch of III type side view.
Fig. 5 is the upright arch of III type side view.
(5) specific embodiment:
The positive and negative convective burning boiler of extreme misery pipe is made of drum, combustion chamber and fire grate shown in Fig. 1～5, and the upright arch 2 of face arch 1, I type, the upright arch 3 of II type and the upright arch 4 of III type are set in the combustion chamber, and fire combustion mouthful is set on upright arch.Fire combustion mouth is arranged at the upright arch of I type bottom, fire combustion mouth is arranged at the upright arch of II type bottom, and II type upright arch top and combustion chamber end face have the space, the upright arch of III type is tracery wall form or through-hole type, fire combustion mouth is all arranged at two kinds of form bottoms, the upright arch of through hole formula III type has fire combustion mouthful in the middle and upper part, flue gas at the flow curve in the combustion chamber shown in Fig. 1 arrow.Adopt normal boiler process technology just can produce, satisfy various index requests.
