Abstract

The utility model relates to the improvement of common small vertical inverse combustion boilers with double layers. The utility model is characterized in that a boiler shell and a boiler bag are made of aluminum alloy. A sealed cavity is formed between the boiler shell and the boiler bag, and the cavity is filled with water to form the container of the boiler. The lower part of the boiler bag is provided with hearths which are distributed from top to bottom, the upper hearth is provided with a water pipe fire grate, and the lower hearth which is communicated with a combustion passage is provided with a cast iron fire grate. The combustion passage which is upwards penetrated through one side of the upper hearth at first is then penetrated through the upper part of the boiler bag, and at last the combustion passage is communicated with a chimney out of the body of the boiler. The utility model has the advantages of high thermal efficiency, safe operation and use, remote possibility of the dangerous of 'explosion ', light weight, simple manufacturing technique, low cost, etc.

Description

Efficient multifunctional boiler

The utility model relates to a kind of minitype vertical type double-layer inverse burning boiler.

Steam pressure when existing small scale vertical boiler is worked is 4 kilograms, and higher to security requirement in the use, the thermal efficiency is generally about 62, and heavy, and cost is also high.

The purpose of this utility model is to provide a kind of thermal efficiency height, does not have the danger of " blast ", and the lower new-type double-layer inverse burning boiler of cost.

For achieving the above object, the technical solution of the utility model is, adopt aluminum alloy materials to make furnace shell and flue, make and form a cavity between furnace shell and the flue, when with various pipes, lid, annexes etc. are installed on the intake-outlet on the furnace shell, steam (vapor) outlet, behind scale removal mouth and the sewage draining exit, this cavity is sealed, sufficient water promptly forms the container of this boiler, the flue bottom has two to be the burner hearth of arranging up and down, and upper furnace adopts water pipe furnace grate, and lower hearth adopts casting furnace grate, lower hearth is connected with burning gallery, the side that this burning gallery upwards passes upper furnace is earlier passed flue top then, and chimney last and outside the boiler furnace is connected.The scale removal mouth is arranged near the upper furnace water pipe furnace grate, and water inlet and sewage draining exit are arranged at around the furnace shell position of the base of slagging tap near ventilating.

Because the utility model is selected at material, the characteristics of aspects such as structural design have the following advantages it: 1. the thermal efficiency is higher than existing same specification product; 2. manipulate safely, do not have the danger of " blast "; 3. long service life; 4. can also can supply boiling water by steam supply, can burn coal and also can burn faggot, and without any need for power supply; 5. weight is light, the smoke evacuation dustiness is little; 6. manufacturing process is simple, cost is low.

Introduce an embodiment of the present utility model below in conjunction with accompanying drawing.

Accompanying drawing 1 the utility model example structure portion.

A-A place profile in accompanying drawing 2 accompanying drawings 1.

K is to view in accompanying drawing 3 accompanying drawings 1.

Accompanying drawing 4 the utility model embodiment schematic appearance.

Select for use δ=3 millimeter aluminum alloy plate materials to make furnace shell (1) and flue (21), the concrete structure shape as shown in the figure, furnace shell (1) and flue (21) form container, wherein the water at each position (comprising the water in the upper furnace water pipe furnace grate (5)) all can circulate, the every position with burning things which may cause a fire disaster, high temperature gas flow generation heat exchange of flue, all contact, the molten materials phenomenon can not occur with water in the container.Pedestal (15) forms with concrete cast, and the base (8) of slagging tap of ventilating selects for use the A3 steel plate of δ=4 millimeter to make, and is connected and fixed by flange, screw between body of heater and the ventilation slag base.Sewage draining exit (16) scale removal mouth (6) locates to add the sealing of red cardboard (20) encapsulant.Burning gallery (3) is " it " font on flue top, to increase heat exchange area and to maintain less burning resistance.The bottom position of water level meter (11) is higher than the upper furnace top, safety valve (10) selection standard valve, make this boiler when normal the use in the container steam pressure be not more than 0.09MPa.It is roughly as follows that present embodiment is manipulated process, fills with water by water inlet (12) in container; When closing lower furnace door (7) and ash gate (8), open upper furnace door (4), air enters upper furnace, and the high temperature gas flow that fired coal combustion forms enters lower hearth and enters burning gallery (3) again, discharges from chimney (9) at last.When opening ash gate (8), air door thus enters, and the high temperature gas flow that the last fired coal combustion of lower fire grating (13) forms enters burning gallery (3) and discharges from chimney (9).Whole burning and high temperature gas flow process of flowing also are the heat exchanging process of water and thermal source in the container, make water be heated and produce steam; When temperature is too high, thermometer (2) has demonstration, should in time overhaul, prescribe a time limit, never allow to continue to use when water level is lower than under the water level meter (11), should stop refuelling, can continue when waiting to inject water to use, after water is boiled, can obtain boiling water from outlet pipe (19) to the predetermined water level value, when needs steam, then can obtain from steam (vapor) outlet on the furnace roof (18); Waste heat case (17) can provide hot water.

Claims
