Abstract

The utility model discloses a beehive coal boiler, comprising a boiler casing, a boiler gallbladder, a firebox, a coal pusher and a slide-way, etc. A pressure-releasing pipe and a water-draining pipe are respectively arranged on the top part of the boiler casing, and the boiler gallbladder is sleeved into the boiler casing. A furnace-arc is arranged in the middle part of the boiler gallbladder, and a vent is arranged on the furnace-arc. At least ten water pipes are vertically arranged on the upper part of the boiler gallbladder. At least a flow-guiding plate is vertically sleeved on the water pipe, and a flue is arranged on the lower part of the water pipe. The firebox is arranged below the boiler gallbladder, and the slide-way is arranged at the bottom of the firebox. The coal pusher is arranged on the outside of the slide-way. The utility model has the reasonable design and enhances and improves the heat-transmitting performance in the boiler, and the heat-transmitting rate can be raised by about 17 percent, and the coal-content of the slag can be decreased to 6 percent below. The contamination is under the one degree standard of national boiler contamination emission. The utility model can be extensively applied to the fields such as the living-community heating, the heating and water-supplying of public bathhouses, hotels and apartments, etc.

Description

The porous briquette boiler

Technical field

The utility model relates to coal-burning boiler, exactly is the porous briquette boiler.

Background technology

The porous briquette boiler that present people generally use, all obtain effect preferably aspect saving coal, the minimizing pollution, but also having some defectives: the one, smoke pipe heat conduction, heat exchange is poor, results in blockage easily; The 2nd, be double wall water around the burner hearth, cause chamber temperature on the low side, burning condition is not ideal enough; The 3rd, the cast iron slideway often deforms or ruptures.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of heat exchange better, can overcome the plugging phenomenon, effectively improves the burning condition of combustion chamber, and can prevent the porous briquette boiler of slideway distortion fracture.

The technical solution of the utility model is such, and the porous briquette boiler is made up of institutes such as furnace shell, flue, combustion chamber, coal pusher and runner devices; The top of furnace shell is equipped with relief tube and outlet pipe respectively, and water inlet pipe is equipped with in the side of furnace shell bottom; Be set with flue in the furnace shell, furnace shell and flue are fixed by several lacing wires; Chimney arch is equipped with at middle part in the flue, makes flue form two spaces up and down, is having exhaust opening near on the chimney arch of fire door one side; At least 10 water pipes vertically are housed in the flue upper space, and the two ends of water pipe all with furnace shell and flue between the space communicate; Be set with at least one deflector with the water pipe vertical direction on water pipe, the bottom and the chimney arch of deflector join, and between the top of deflector and the upper wall of flue a space are arranged; Flue is equipped with in bottom at water pipe, and stretches out outside the stove by furnace shell; The lower space of chimney arch is the combustion chamber, is provided with runner device in the bottom of combustion chamber, and the outside of runner device is provided with coal pusher.

Described water pipe is inclined upwardly 2 °-5 ° backward from the stokehold direction

Described runner device is made up of slideway and water pipe frame; The water pipe frame is a rectangle, along being laid with slideway on the water pipe on two long limits of water pipe frame.

The utility model is reasonable in design, optimizes and improved heat conduction working condition in the stove, and the thermal efficiency can improve about 17%, and ash content carbon drops to below 6%, and pollutant is lower than national boiler pollutant discharging primary standard.The field such as heating, water supply that can be widely used in heating station, common plunge bath, hotel and apartment.

Description of drawings

Accompanying drawing 1 is looked cross-sectional schematic for porous briquette boiler master; Wherein: 1 furnace shell, 2 flues, 3 relief tubes, 4 outlet pipes, 5 water pipes, 6 deflectors, 7 chimney arch, 8 exhaust openings, 9 flues, 10 fire doors, 11 combustion chambers, 12 coal pushers, 13 slideways, 14 water pipe framves.

Accompanying drawing 2 cuts open schematic diagram for the porous briquette boiler right side office of looking; Wherein: 15 lacing wires, 16 water inlet pipes.

The specific embodiment

As shown in drawings, the porous briquette boiler is made up of institutes such as furnace shell 1, flue 2, combustion chamber 11, coal pusher 12 and runner devices; The top of furnace shell 1 is equipped with relief tube 3 and outlet pipe 4 respectively, and water inlet pipe 16 is equipped with in the side of furnace shell 1 bottom; Be set with flue 2 in the furnace shell 1, furnace shell 1 and flue 2 are fixed by several lacing wires 15; Chimney arch 7 is equipped with at middle part in the flue 2, makes flue 2 form two spaces up and down, is having exhaust opening 8 near on the chimney arch 7 of fire door 10 1 sides; In flue 2 upper spaces, at least 10 water pipes 5 are housed vertically, and the two ends of water pipe 5 all with furnace shell 1 and flue 2 between the space communicate; Be set with at least one deflector 6 with the water pipe vertical direction on water pipe 5, the bottom of deflector 6 and chimney arch 7 join, and between the upper wall of the top of deflector 6 and flue 2 space are arranged; In water pipe 5 bottoms flue 9 is housed, and stretches out outside the stove by furnace shell 1; The lower space of chimney arch 7 is combustion chamber 11, and 11 bottom is provided with runner device in the combustion chamber, and the outside of runner device is provided with coal pusher 12.

Described water pipe 5 is inclined upwardly 2 °-5 ° backward from the stokehold direction

Described runner device is made up of slideway 13 and water pipe frame 14; Water pipe frame 14 is a rectangle, along being laid with slideway 13 on the water pipe on 14 two long limits of water pipe frame.

During use, at first by water inlet pipe 16 between furnace shell 1 and flue 2 the space and water pipe 5 in be filled with water to desired height.Place drop grate on the slideway 13, on fire grate, pile up porous briquette, moulded coal is advanced combustion chamber 11 by coal pusher 12.The moulded coal of burning is at first with chimney arch 7 roasting warm, to improve stove internal combustion condition; Simultaneously, hot cigarette enters flue 2 upper spaces by exhaust opening 8, and under the effect of deflector 6 water pipe 5 is carried out the curve heating, thereby reaches the purpose of effectively utilizing heat energy.When water temperature in the stove raises generation pressure, carry out pressure release by relief tube 3, safe in utilization to guarantee.
