Abstract

PURPOSE: A high pressure hot wind blower boiler is provided to heat as a how wind of a high temperature by maximally absorbing the combustive heat of a burner and to reduce fuel costs by efficiently using the combustive heat. CONSTITUTION: A perspective window(3) and a burner are installed in a combustion chamber(2) of a boiler body. The combustion chamber is connected to an exhaust gas collecting chamber(6) through many heat exchanger pipes(7). Then, combustive heat is delivered through the heat exchanger pipes. An air compressor is installed in an input port(9) of the boiler body to inject air and to absorb the heat from the combustion chamber. After that, the heat from the heat exchanger pipes and the exhaust gas collecting chamber are sequentially absorbed and collected in a first heat collecting chamber and discharged through an exhaust duct(12). While absorbing heat, compressed air is spirally circulated through a dual heat exchange pipe(8) and heated up gradually. Thus, heating efficiency is instantaneously enhanced.

Description

High Pressure Hot Air Boiler {omitted}

The present invention relates to a high pressure hot air boiler which blows air to an air compressor system so that high temperature hot air can be used as a steam boiler.

Conventionally used boilers require a lot of fuel costs to boil water to use temperature as steam pressure, but the high pressure hot air boiler invented is a boiler that can be used as drying heat or heating heat by using only air.

The special feature is to make double pipes in the outer wall of combustion chamber and soot gas collection chamber connected by several heat exchange pipes, to make the surface thin when air is transported, and to flow the air through the gap, It is a boiler that can significantly reduce fuel costs by minimizing heat loss by allowing heating at high temperature in time.

Conventional steam boilers take a long time to boil water because they boil water and use the indirect heat, which requires a lot of fuel costs, and because water is used to boil water, it is necessary to wait for a long time. It was not possible to use high temperature heat, and when a lot of hot air or heat was needed, the accompanying mechanical equipment had to be installed.

And because of the pressure using water, it is included in fuel cost due to corrosion and water consumption.

Although there was a risk of machine stoppage and winter freezing due to water shortages, air pressure boilers were invented for efficient use by solving these problems.

Conventional boilers require a long time because the larger the capacity is used to boil water at a time, but the high pressure air boiler invented significantly reduces fuel savings by distributing air into thin gaps and instantaneous high temperature heat. Can be.

In order to solve the various problems as described above, the present invention can absorb the combustion heat of the burner to the maximum so that it can be constructed in a very reasonable structure and heated by high temperature hot air and minimize the heat loss by the efficient use of the combustion heat. It is to provide a hot air boiler that can significantly reduce fuel costs,

Structural features

The combustion chamber 2 formed in the boiler body 1 is provided with a see-through window 3 and a burner 4, and between the flue gas collection chamber 6 in which an electric combustion chamber 2 and a waste gas discharge port 5 are fixed. To transfer the burned heat through several heat exchange pipes (7),

At the inlet 9 of the collecting cylinder 10 formed in the lower part of the boiler body 1, a compressed air blowing machine is installed, and the hot air heated by the heat of the combustion chamber 2 collects in the hot water collecting chamber 11 to the discharge duct 12. When used in the combustion chamber (2) and the primary collecting cylinder (10) to absorb the heat of the heat exchange pipe (7) while entering the heat passage (13) to push up into the double pipe heat exchange pipe (8) By rotating in the spiral (14) direction to increase the residence time is to create a high temperature heat to improve the efficiency.

1 to 2, the combustion chamber 2 formed inside the boiler body 1 is provided with a see-through window 3 and a burner 4, and the electric combustion chamber 2 and the discharge gas outlet 5 ) Is connected to a plurality of heat exchange pipes (7) between the soot gas collection chamber (6) fixed to the combustion heat to the heat exchange pipes (7),

An air compressor system or a pump is installed in the inlet 9 formed in the lower portion of the boiler body 1 and blown to be heated by heat dissipation of the heat exchange pipe 7 to be collected in the hot water collecting chamber 11 and discharged to the discharge duct 12. In that way,

The hot air passage 13 is formed between the combustion chamber 2 and the primary collection cylinder 10, while the hot air passage 15 is formed by a double pipe pipe 8 outside the heat exchange pipe 7 and turns into a spiral 14, It is gradually heated to collect in the heat collecting chamber 11 to be discharged to the final discharge duct (12).

Reference numeral 16 denotes a body cover, and 17 denotes a pedestal.

Referring to the operation of the present invention as follows.

When the air is to be heated by high temperature heat, the burner 4 is first ignited, the fire is checked by the see-through window 3, and the blowing air of the burner 4 is adjusted. The exhaust gas collecting chamber 6 is collected through the exhaust gas collection chamber 6 and discharged to the waste gas discharge port 5, where the combustion chamber 2 and the heat exchange pipe 2 are heated by high temperature heat.

In this state, when the air compressor system is operated and injected into the inlet 9, the heat is absorbed from the inner wall of the combustion chamber 2, and is transferred to the double pipe pipe 8 and the hot air passage 13 provided on the outer wall of each heat exchange pipe 7 to rotate. While being heated by hot air and gradually gathered in the hot air collecting chamber, it is discharged to the discharge duct 12. The heat absorbs the heat of the heat exchange pipe 7 as much as possible by lengthening the residence time while rotating in a spiral as shown in FIG. ,

Unlike conventional boilers, the heat is instantaneously heated so that the hot air is dissipated into several heat exchange pipes 7 so as to allow high temperatures up to 700 ° C. You can do it.

When the heat exchange pipe (7) formed in the boiler is installed and the air passes outside the combustion chamber (2) to make a thin surface when absorbing the heat of the heat exchange pipe (7) and transferred to the double pipe (8), By turning a small amount of hot air air divided into several spirals, the residence time can be lengthened, and a high temperature can be instantaneously generated, thereby significantly reducing fuel costs.
