Description

Coal, oil, gas combined boiler

The present invention relates to a pollution-free boiler device having no pollution due to exhaust gas by forming a desulfurization device and a CO ₂ gas removal device to extend the use of fossil fuels limited by the heat utilization effect as a coal oil gas combined boiler.

In general, small boilers that have been widely used in the past have inserted tube tubes into circular tanks so that heat can pass through the tubes to improve thermal efficiency. However, large boilers are not possible due to the vapor pressure relationship. It is a tube tube that introduces water into the tube tube around the firebox, and this tube is listed in a row only on the fuselage wall surface, and the body is fixed and cannot be rotated when it is manufactured and repaired. Since the whole inside is a firebox and the upper temperature is higher than the lower temperature ratio, it is not used to generate steam in the process of heating the water pipe, and it is exhausted and the high temperature is discharged to unnecessary micron, so the heat loss is huge and the inside of the firebox is wide. Convection is weak and does not generate frictional heat Even if the supporting means such as oil spray, lime powder spray or heated sand spray is added to the firebox, it does not increase combustion efficiency due to excessive exhaust heat and emits large amounts of toxic gases such as sulfur dioxide, carbon monoxide and carbon dioxide. There are many disadvantages in terms of the arrangement of the combustion chamber and the combustion conditions of the combustion chamber.

The present invention is a device that is contrary to the conventional structure in order to fundamentally solve and supplement the conventional drawbacks as described above to install a combustion chamber at the left end of the body to supply the first and second air to increase the combustion environment to almost complete combustion furnace By reducing the generation rate of carbon monoxide significantly and stacking water pipes in the body, the water pipes were interviewed with each other. The space between them was filled with concrete to block the vapor pressure, which makes it possible to enlarge the pipes. The combustion heat and the desulfurization device generate strong frictional heat by passing the heat of heat passing through the narrow corridor at high speed, eliminating the emission of toxic gases such as sulfurous acid gas and carbon dioxide, and almost no pollution is generated. Providing boilers composed of both oil and gas to be.

If a large number of pipes are tightly threaded between the threads and coal is supplied to the limestone pants above the combustion chamber, the large coal will be Dropping on the stall along the water pipe slope Falls between the water pipes and hits the refractory bricks, injects compressed air into the ventilation grooves between the ramps of the refractory bricks, and injects air from the lower side to completely burn the coal, and the exhaust gas is reheated in the cyclone to desulfurize. When the desulfurization by spraying the slaked lime in the combustion chamber, the moisture contained in the coal vaporizes and combines with the slaked lime when it passes through the corolla, and there is a closed end that is pressed against the corolla wall by the temperature difference inside and outside the corolla. When it burns, there is no moisture, so it is sprayed with lime in the combustion chamber to desulfurize, so that when passing through the corolla, sulfur dioxide is transformed into calcium sulfite, which does not corrode the corolla and the boiler 30 has no advantage of oil consumption. Configured.

That is, several brackets (2) attached to the lower surfaces of the various choruses (1) of the boiler are mounted on the pedestal (4) with pins (3) and hydraulic cylinders (5) for adjusting the inclination angle of the body are mounted.

Limestone uniformly supplied by the flow 18 'and supplied to the combustion chamber 13b and heated to the limestone inlet 17 is also heated by preheating of the combustion chamber 13b in the downcomer 19 by the screw 18. The rack gear 21 (timer device) is adjusted to fall according to the heating state, which is rolled or blocked by the dropping hole 20. As soon as it is rolled down, water is sprayed from the bottom to obtain powdered slaked lime.

The operation thereof is as follows.

The boiler of the present invention is equipped with brackets and several hydraulic cylinders 5 at the bottom of several frames to pipe the water pipes and corollas between the left and right chambers 9a, 9c for a long time, so that heat efficiency passes only through the corollas. It is superior and the coal dropped from the coal drop passage during operation When dropped on the limestone jersey (13C) at the top of the embroidery tube, the large lump is piled up on the roll and the powder and the small mass When it escapes between the embroidery tubes and falls on the inclined surface of the refractory brick 15, it is pushed by the compressed air sprayed into the plurality of ventilation grooves 16 and adheres to the upper layer of the combustion chamber 13b to burn and float while the air supply is sufficient and almost complete. Combustion and exothermic action is strong, and when the flame passes into the flame tube 9b by the pressure of the air injected from the lower side and the high pressure of the compressed air, the convection action increases as the temperature increases and passes through at high speed and is strong in the flame. Since the thermal efficiency is increased according to the frictional strength in heating the corolla while generating frictional heat, the water in the water pipe (9) surrounding the corridor is rapidly heated to generate an explosive vapor and a high-pressure steam is generated in the steam tank (12). In the process of passing through the dry steam engines 11b, the high pressure dry steam, which is dry in the dry steam chamber 10, gathers in the steam collection pipe 11a and passes through the steam transfer pipe 7; Passing through the flame of the upper side of the combustion chamber (13b), and reheated to operate a turbine (not shown) connected to the high-pressure dry steam through the discharge pipe (10 ').

The steam generated in this process is divided in the rainwater chamber, and the steam is compressed in the steam tank 12, and the hot water is circulated through the hot water circulation pipe 9 'to the left water chamber 9c, and the hot water is circulated from the high temperature to the low temperature. Functioning, vertical water pipe (11) and street water pipe (8) Embroidery pipes also increase the vaporization function in addition to vaporization, and the unburned residue collected in the dry steam chamber 10 is recovered in the combustion chamber 13b through the remnant recovery pipe 23 and reburned. In some cases, it is discharged by connecting to the carbon material feed screw (18). The heat discharged to the corolla 9b enters the cyclone 30 while heating the dry steam engine, surrounds the central exhaust pipe 29a, turns, descends, and rises and discharges to the lower opening. The hydrated lime powder is blown strongly by the blower 33 at the bottom of the central exhaust pipe 29a in the blower pipe, and at the same time, the flame of the burner 33 'is oxidized by incineration of the hydrated lime powder, carbon monoxide and sulfur dioxide at a high temperature, and the carbon monoxide is converted into carbon dioxide. And the sulfurous acid exhibits an effective desulfurization action of the desulfurization device 28 which causes a predetermined reaction to become calcium sulfite, and the desulfurized gas becomes calcium sulfite and passes through the exhaust pipe 29 'to the bottom of the cooling water device 31. Through the outlet

In the process of passing through the back filter 35, particulate carbon, heavy metals attached to the slaked lime are collected, and water is baptized into the gas passing through the plumb vertical pipe 36 to dissolve primary CO ₂ and CO ₂ dissolved in water. In the process of passing through the granular vertical pipe 37, the lime is sprayed baptized and washed down the limestone, so that the carbon dioxide is dissolved in water at a proper mixture and at an appropriate temperature, becomes carbonate ions, combined with calcium ions, and becomes calcium carbonate. The gas body discharged in this way discharges pollution-free gas. In the combustion process, the combustion pipe passes through the fire pipes 9b into the water pipe 9 and becomes a double pipe to block the vapor pressure and to remove toxic and harmful gases from the desulfurization device 28. It is completely absorbed.

When using oil, the cyclone blower burner slaked lime cyclone stops operation, the blower 42 is replaced with a burner, and the slaked lime is injected from the slaked lime cyclone 42 'so that the sulfurous acid gas becomes calcium sulfite, and the blower 41 is secondary. Complete combustion with an air supply and heated refractory to heat the oil vaporized gas and to release calcium sulfite from the cyclone.

In the present invention, the water pipes are stacked in multiple layers between the left and the rainwater rooms to be interviewed, and the corollas are inserted into the water pipes so that the double pipes constitute the left and rainwater rooms in which the dense pipes are formed. As it can rotate left and right, it is easy to manufacture, check, and repair by extending these double pipes, and the convection action is increased because the water pipes and corollas are lengthened, creating a strong suction force. It causes friction and increases the thermal efficiency, so that the vaporization function is improved. In this structure, when the high temperature of the combustion chamber passes, the heat is gradually changed to a low temperature, and the exhaust heat is discharged to a very low temperature, which requires coal and oil. Significantly reduced, sulfur dioxide and carbon dioxide are also reduced, and the time for vaporization and desulfurization With a sulfur dioxide is transformed into calcium sulfite and carbon dioxide gas absorber action has the effect of preventing thermal efficiency and air pollution as a breakthrough device in which the calcium carbonate and sodium carbonate.
