The upper boiler body and the lower boiler body are presented as cuboid shapes so that smoke tubes can be placed in a relatively great amount and heating surface is enlarged. Higher heat efficiency can be obtained. The utility model has the advantages of non-accumulating chimney spot, complete combustion, high thermal efficiency, large water capacity, strong heat storage capacity and good heat stability when in operation. The heating boiler is especially adapted for residential district cryogenic floor heating system and has a pronounced saving coal effect. The heating boiler also has the advantages of good effect of dust removing, natural ventilation and saving electricity and energy.
Description
Technical field
The utility model relates to a kind of atmospheric vertical heating stove.
Background technology
Existing atmospheric vertical heating stove majority is a round, is subjected to structural limitations, and heating surface is little, and the thermal efficiency is lower, and smoke discharge amount is big, when dedusting, and must additional external deduster.Effect of natural ventilation is bad, needs to adopt air-introduced machine, air blast etc. to carry out forced ventilation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of high-effective dust-removing low-temperature water heating heating stove, thermal efficiency height, and effect of natural ventilation is good, has also solved the problem from dedusting simultaneously.
High-effective dust-removing low-temperature water heating heating stove of the present utility model, comprise stove seat, lower furnace body, upper furnace body, be provided with the combustion chamber in the lower furnace body, the upper furnace body top is communicated with worn-out mouthful water supply tank, and splendid attire water in the upper furnace body is water interlayer between lower furnace body wall and the combustion chamber, water interlayer is communicated with upper furnace body, it is characterized in that being provided with in the upper furnace body some vertical smoke pipe bundles, smoke pipe is fixed on the last lower perforated plate of upper furnace body, and the smoke pipe bottom communicates with the combustion chamber.
Vertical smoke pipe places the water of upper furnace body, the water in the high-temperature flue gas parallel baffled smoke pipe heating upper furnace body, and the tube wall laying dust is few, good heat conductivity, thermal efficiency height.
Also be provided with the flue casing coupling at the upper furnace body top, flue casing coupling top connects chimney, and the smoke pipe top communicates with the flue casing coupling, and the flue casing coupling is provided with shoot door, easy access, deashing and furnace stopping maintenance.The utility model has formed a flue casing coupling than large space on the top of upper furnace body, constituted gravity settling chamber, and trickle soot dust granule settles down under the effect of gravity, return the combustion chamber through smoke pipe, discharge through fire grate, played the effect that purifies flue gas, significant dust removing effects is arranged.Therefore the utlity model has from the dedusting effect, dedusting and boiler are combined, floor space is little, integral installation.The utility model structure up/down perforation leans on gravity-flow ventilation simultaneously, and combustion chambers burn is abundant, has also improved the thermal efficiency.
According to the size of thermal power, one or more combustion chambers arranged side by side can be set in the lower furnace body, have observation door and fire door (coal filling hole) on the combustion chamber.Each combustion chamber is by the draft of chimney, and observation door is suitably opened, and forms " secondary wind ", and high-temperature flue gas through " secondary wind " disturbance parallel baffled smoke pipe that makes progress, enters chimney through the flue casing coupling in the combustion chamber.The utility model gravity-flow ventilation, little negative-pressure firing, regulate load and just regulate burning, according to different coals, determine suitable burning zone height, at the heating stove top flue shutter can be set, regulate exhaust smoke level by flue shutter, also just regulated simultaneously air output and " secondary wind " amount of fire grate bottom,, reached the purpose of regulating load by regulating temperature and the flue-gas temperature that air output has also just been regulated burning coal layer.
The utility model upper furnace body, lower furnace body the best are cuboid, can arrange smoke pipe in larger amt ground, increase heating surface, obtain the higher thermal efficiency.Water capacity is big, and heat storage capacity is strong, Heat stability is good.
Advantage of the present utility model:
Not long-pending crock in service, sufficient combustion can be arranged heating surface in larger amt ground, thermal efficiency height, water capacity is big, and heat storage capacity is strong, and Heat stability is good is fit to residential area low-temperature floor heating system very much, has significant effect of coal saving.Good dedusting effect is beneficial to environmental protection; Electric energy is saved in gravity-flow ventilation; Maintenance, easy maintenance.
