Abstract

Disclosed is an upper-combustion coal environmental-friendly energy saving boiler, comprising a furnace body, a grate, a combustion chamber, a heat exchanger and a heat accumulating cover arranged inside a flue, a coal inlet door and a cinder removing door. The utility model is characterized in that a grate sliding rail guiding block is arranged at the outer side or the inner side of two sides of a sliding rail beneath the grate; the heat exchanger and the heat accumulating cover inside the flue are made by strengthening fire resistance materials between transverse water exhausting pipes. The utility model has the advantages of fast heating temperature, high thermal efficiency and low smoke resistance. The grate with the sliding rail guiding block is adopted so that the blocking of the grate inside the combustion chamber can be prevented; the coal on the grate can be kept a certain distance from two sides of a hearth; the coal can be combusted in high temperature.

Description

Burning in upper part coal energy-saving environmental protection boiler

The utility model relates to a kind of boiler, especially a kind of burning in upper part coal energy-saving environmental protection boiler.

Advantages such as moulded coal acts as a fuel than diffusing coal, has the efficiency of combustion height, and calorific value is stable, and gravity-flow ventilation is good, and is easy to use, and operating cost is low.In order to reach the above-mentioned combustion efficiency of moulded coal, a cover and the stove and accessory that moulded coal burning is complementary must be provided, make the moulded coal stove and accessory can continuous burning.At present, existing burning in upper part coal burning boiler is of a great variety, and moulded coal stove briquet changing device is also had nothing in common with each other, as ZL94201407.3 disclosed " a kind of industrial heating furnace that burns moulded coal ", its briquet changing device adopts travelling gear chain mechanism, moulded coal is added from fire door after, enter burner hearth with the transmission of chain.This briquet changing device complex structure, maintenance difficult; ZL88218935.2 described " moulded coal stove coal-feeding and deslagging device " and ZL91211720.6 disclosed " moulded coal stove coal changing device structure " for another example, its coal row be placed on the slide rail, and move forward and backward along slide rail and to be used to into coal slag dumping.The above-mentioned coal row who is placed on the slide rail, in moving process easily about skew, jam is in the combustion chamber, the difficulty of fixing a breakdown under the high-temperature condition influences boiler easily and normally moves.

In addition, existing burning in upper part coal burning boiler also the ubiquity burner hearth to hang fire highly low, the flue angle is little, the dead angle is big, adopts the pyrotechnics pipe to carry out the smoke convection heat exchange mode, under the low situation of air pressure, is easy to produce the disadvantage of anthracemia.The pyrotechnics pipe of boiler is easily wall calendar ash, obstruction under low-temperature condition, influences boiler service life and heat exchange effect.Existing burning in upper part coal stove ubiquity is banked up a fire not tight, and all fire doors close and do not lean on, and particularly the air distribution door is taked drawing and pulling type, and this air distribution door substantially all the phenomenon of leaking out, ventilate can occur.

The utility model has overcome the deficiency of above-mentioned prior art, and the burning in upper part coal energy-saving environmental protection boiler that provides a kind of fire grate to have the tracks positioned device is provided one of its purpose; Two of its purpose is to provide the burning in upper part coal that is provided with heat exchanger and heat gathering cover in a kind of flue energy-saving environmental protection boiler.

Above-mentioned purpose of the present utility model is achieved through the following technical solutions.

A kind of burning in upper part coal energy-saving environmental protection boiler, comprise the combustion chamber that is arranged in the body of heater, the fire grate that is placed on the slide rail is arranged in the combustion chamber, be provided with heat exchanger and heat gathering cover in the body of heater flue, body of heater is provided with coal inlet and clean-out door, it is characterized in that the following inboard or the outside of said fire grate, be provided with rail-guided of fire grate near the slide rail both sides.Above-mentioned slide rail can directly be fixed on the water pipe that is connected with boiler recirculated water.The above-mentioned fire grate that has the slide rail guide pad can directedly move in moving process, prevents that the fire grate jam is in the combustion chamber.

A kind of burning in upper part coal energy-saving environmental protection boiler, comprise the combustion chamber that is arranged in the body of heater, the fire grate that is placed on the slide rail is arranged in the combustion chamber, be provided with heat exchanger and heat gathering cover in the body of heater flue, body of heater is provided with coal inlet and clean-out door, it is characterized in that said heat exchanger and heat gathering cover adopt reinforcing refractory material composition between the horizontally-arranged water pipe.This boiler can utilize the natural pressure of atmosphere, and the high-temperature flue gas curve is risen, and resistance is little in the heat transfer process.Simultaneously, can increase furnace heating surface and radiation effect again,

The air distribution door leaks out in order to solve, ventilation problem, the coal inlet of above-mentioned body of heater and clean-out door are separately positioned on body of heater and are on the end face and side of an angle of 90 degrees, and the way of taking layback air distribution door and side supporting plate to slag tap, reduce big and stove front and advance the heat loss that coal, the opposite unreasonable setting of slagging tap afterwards bring because of fire door.

The utility model adopts the water screen tube horizontally-arranged to reinforce, with heat exchanger and the heat gathering cover in the prefabricated heat exchange flue of refractory cement, make high-temperature flue gas can utilize the natural pressure curve of atmosphere to rise, reduce flue gas resistance in the heat transfer process, increase furnace heating surface and radiation effect simultaneously.Facts have proved this smoke convection heat exchange design, make stove and accessory have that programming rate is fast, thermal efficiency advantages of higher.Owing to adopt water pipe slideway oriented movable fire grate at design aspect, fixed rack guide pad according to grate area design different spacing, make moulded coal and burner hearth both sides above the fire grate keep a determining deviation, ventilation send oxygen good, the prototype coal stove can not occur links to each other with the furnace wall because of moulded coal, the bad high phenomenon of the phosphorus content of slagging tap, the good energy-conserving effect of causing burns.This boiler has been changed a social system original pull plate air distribution door, the way of taking layback air distribution door and side supporting plate to slag tap, minimizing big and stove front is advanced the heat loss that coal, positive unreasonable setting of slagging tap later bring because of fire door, has demonstrated fully environmental protection, the energy-saving effect of this moulded coal stove.In the making and settlement of taking multi-use aspect the small-sized stove and accessory as far as possible, when cooking, fire grate is moved to cooking stove mouth place, the accent windscreen at chimney place is transferred to suitable position; The time spent is not shifted the burner hearth the inside heating place that is heated onto.Simultaneously, want to eat food roasting, can be placed on fire door import department to barbecue rack.Northerner's hot a heatable brick bed of liking sleeping can directly lead to the stove chimney in the flue of a kang.The utility model can be realized the effect of multi-use.
