The utility model content

Technical problem to be solved in the utility model be to provide a kind of fire smoke gases passage for " ∩ " type, can make combustion flame and high-temperature flue gas long flow path, holdup time in the fire smoke gases passage long, improve the energy saving and environment friendly heating boiler of the thermal efficiency greatly.

The utility model will solve the above-mentioned technical scheme that technical problem adopted:

A kind of energy saving and environment friendly heating boiler, comprise boiler body, be positioned at boiler body below the combustion chamber, be positioned at the fire smoke gases passage that links to each other with the combustion chamber of boiler body, the chimney that links to each other with the fire smoke gases channel outlet, ring fire flame exhaust gases passes inwall is furnished with cyclic water jacket, vertically be provided with a cavity type demarcation strip in the described fire smoke gases passage, be equipped with the communicating pipe that is connected with cyclic water jacket on the cavity type demarcation strip; This demarcation strip is separated into " ∩ " type structure with the fire smoke gases passage, and the import and export of the fire smoke gases passage of its " ∩ " type structure are connected with combustion chamber and chimney respectively.

Be provided with between described combustion chamber and the boiler body for the collection flue of flame by the fire smoke gases channel transition of combustion chamber in boiler body, the collection flue is the flat passage that is positioned at the combustion chamber side top, its flame inlet communicates with the combustion chamber, and its flame export communicates with the inlet of fire smoke gases passage.

As improvement of the present utility model, described communicating pipe is managed layer up and down along fire smoke gases passage branch multilayer, and each manages being arranged in parallel to each other in the fire smoke gases passage communicating pipe of layer.

Parallel between the communicating pipe of described each layer and the orientation unanimity, the placement direction of communicating pipe is horizontal by 0 °-30 ° angle.

As the novel further improvement of this usefulness, described communicating pipe, every neighbouring two water pipes of managing layer were misplaced mutually.

Further improve as of the present utility model, the horizontal direction of described communicating pipe is perpendicular with the horizontal axis along its length of collection flue.

Above-mentioned energy saving and environment friendly heating boiler is provided with the dust collection chamber that is with the ash disposal mouth with the chimney place of communicating below the fire smoke gases passage.

The obtained technological progress of the utility model is: the energy saving and environment friendly heating boiler of said structure is because the fire smoke gases passage is " ∩ " type structure, in addition in the fire smoke gases passage be provided with in horizontal direction communicating pipe and levels between be misplaced mutually advancing of flame and flue gas brought very big resistance, can make flame, advance in flue gas curved path in the fire smoke gases passage, not only making its entrained heat be recycled water fully absorbs, and flue dust also can obtain abundant sedimentation in the fire smoke gases passage, thereby reach energy-conservation, this heating stove of environmental protection can make flame, flue gas is circuitous advancing in the fire smoke gases passage, not only make its entrained heat be recycled water fully and absorb, can guarantee that like this chimney institute smoke discharging reaches environmental protection, the purpose that environment is polluted not; The setting and the layout of multilayer communicating pipe of fire smoke gases passage hollow cavate demarcation strip increase endotherm area widely, so that the thermal efficiency is improved widely.The utility model is applicable to various vertical, horizontal heating boilers.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
