Abstract
The utility model relates to a natural-ventilation normal-pressure boiler with a single fire grate, which comprises a peripheral water tank, a hearth, a flue and an air collecting chamber. The utility model is characterized in that the natural-ventilation normal-pressure boil adopts a single fire grate so as to have no scale formation and adopts natural ventilation so as to have no electricity consumption; the hearth form a conical shape and has preheated secondary air supply, the combustible component of coal can be sufficiently combusted in the hearth, and then the utility model achieves the goal of smoke elimination and dust removal; compared with the prior art, the utility model has the advantages of labor and material saving, long service life and easy operation.
Description
The utility model relates to a kind of boiler for domestic, especially a kind of single fire grate normal-pressure boiler of gravity-flow ventilation.
Existing normal-pressure boiler mostly is the anti-cold wall type structure of heating up water of double grate, its shortcoming is that the easy fouling life-span of water pipe furnace grate is short, secondary solves smoke elimination to wind and the single fire grate normal-pressure boiler on the market adopts by force more, though adopt this kind method to play certain effect, by force to wind need electric fan, noise is big, dust discharge is high.
The purpose of this utility model is to disclose a kind of single fire grate, the normal-pressure boiler of gravity-flow ventilation energy smoke abatement and dust control.
Take following technical scheme for finishing above-mentioned purpose: boiler is made up of peripheral water tank, burner hearth, flue, collection chamber etc., it is characterized in that, described burner hearth is that a taper type structure burner hearth bottom is palisade list fire grate and is communicated with the collection chamber of bottom, in burner hearth, provide combustion air by collection chamber one time by single fire grate gap, lower furnace portion outer wall ring is with flame-proof thermal insulation material, not influenced by water-cooling wall around making coal-fired layer, improved furnace temperature; The upper furnace smoke uptake, the uniform overfiren air port in upper furnace crater place provides secondary to wind (oxygen) in burner hearth, and mix the back with uncombusted coal gas and form secondary and fully burn, reach the purpose of smoke abatement and dust control, providing of secondary wind is to be imported by collection chamber by being distributed on the outer secondary air channel of hearth wall, and enter the burner hearth crater through flame retardant coating and hearth wall preheating, giving fully, burning creates conditions.
The single fire grate normal-pressure boiler of the disclosed gravity-flow ventilation of the utility model compared with prior art has single fire grate, and gravity-flow ventilation is easy to operate, the fire grate non-scaling, and smoke abatement and dust control is advantage completely.
Below in conjunction with the embodiment accompanying drawing this normal-pressure boiler is described in further detail.
As shown be the structural profile schematic diagram of the single fire grate normal-pressure boiler of this gravity-flow ventilation.
Illustrate: 1, collection chamber; 2, refractory material filling bed; 3, secondary ventiduct; 4, taper burner hearth; 5, peripheral water tank; 6, fire grate; 7, fire coal; 8, secondary air mouth; 9, uncombusted combustion gas; 10, crater; 11, flue.
Referring to figure, by taper burner hearth 4 and flue 11 constitute inner furnace, burner hearth is the primary zone, flue forms secondary combustion chamber.Inner furnace is peripheral water tank outward, transverse row is shown the water pipe of the peripheral water tank of some connections to improve the thermal efficiency in flue, the wind of collection chamber divides two-way to enter burner hearth, one the tunnel after fire grate 6 bottoms enter burner hearth with coal-fired mixed combustion, another road through secondary wind inleting tube through after the flame retardant coating high-temperature region preheating together with the burner hearth crater, mix the back with uncombusted coal gas and fully burn, thereby reach the purpose of smoke elimination at secondary combustion chamber.Refractory material filling bed 2 mainly is to be used for improving furnace temperature and the preheating of secondary wind to create conditions for fully eliminating smoke, and the height of this refractory insulating layer is 100-350mm, and thickness is advisable between 10-350mm.Water layer is thicker herein owing to the tapered structure in burner hearth high-temperature region, does not resemble easy burning the water-cooling wall twin furnace in the stove after the water fouling, so prolonged the service life of stove.
Claims (2)
1, the single fire grate normal-pressure boiler of a kind of gravity-flow ventilation, contain peripheral water tank, burner hearth, flue, collection chamber, it is characterized in that described burner hearth is a taper type structure, burner hearth bottom is a palisade list fire grate, and the connected set air chamber, lower furnace portion outer wall ring is with flame-proof thermal insulation material, the upper furnace smoke uptake, its frustum burner hearth crater place has some uniform overfiren air ports to lead to burner hearth, and secondary air channel is positioned at outside the hearth wall and with the collection chamber of boiler bottom and is communicated with.
2, want 1 described normal-pressure boiler as right, it is characterized in that the height of the flame-proof thermal insulation material that described lower furnace portion outer wall ring encloses is 100-350mm, thickness is 10-350mm.
