Description

Brown gas plant and burner for accelerate combustion

The present invention relates to a brown gas plant and a combustion promotion burner for combustion promotion for heating a kiln used for firing raw materials in a cement plant, and specifically, to supply complete combustion by supplying brown gas to the center of a combustion chamber for burning fossil fuel. The present invention relates to a brown gas plant and a combustion promotion burner for combustion promotion that can maximize energy efficiency and significantly reduce its cost.

In order to fire fuel produced in large quantities in a cement plant, etc., a large-scale kiln is used, which is a fact that many fuels and costs are generated, and thus, conventional combustion technology alone does not find a proper method for reducing fuel.

Fossil fuels such as bunker-C oil or coal are mainly used as fuels for heating kilns in cement plants, but nowadays, coal is widely used by air transfer.

Due to the use of such low fuel, a large amount of pollutants are discharged, and as a way to solve the pollution problem, a large amount of pollution prevention facilities such as cyclone bag filter, hot coat rats, etc. must be additionally installed.

Conventional combustion method mainly adopts a method of blowing air into the combustion chamber, but in the case of low-grade fuel, the heat loss disappearing into the chimney due to incomplete combustion is inevitably enormous, for example, when using bunker-C oil as fuel. Currently, about 70% of the waste is left in an incomplete combustion state.

The present invention has been proposed to solve this situation, and has been conducted to study the complete combustion of fossil fuels by supplying a certain amount of brown gas having the following intrinsic properties as a combustion catalyst for fossil fuels.

Brown gas refers to a mixed gas in which hydrogen and oxygen are mixed in a ratio of 2: 1 by the electrolysis method of water, and these are four characteristics that are summarized as completely pollution-free, completely burned, improvised, and thermonuclear. It is manger.

It is an object of the present invention to supply brown gas (ie, H2 and O2) to the center of a flame where fossil fuel is burned, thereby promoting combustion, thereby inducing incomplete combustion to complete combustion, and burning fuel wasted due to incomplete combustion. As a result, it is to provide a brown gas plant and a combustion promotion burner for combustion promotion that can save enormous fuel costs.

The overall configuration of the present invention for achieving the above object is a brown gas plant for producing a large amount of brown gas to supply to the combustion promotion burner; Three brown gas injection means disposed at an end of the brown gas supply pipe and injecting brown gas into the combustion chamber; A first air supply pipe for combustion mounted cylindrically on the outer circumferential surface of the Brown gas supply pipe; A fuel supply pipe formed on an outer circumferential surface of the first air supply pipe; The second air supply pipe for combustion is formed on the outer circumferential surface of the fuel supply pipe so as to constitute a combustion promotion burner in the form of a multiple pipe.

Hereinafter, the overall configuration of the present invention and specific effects obtained therefrom will be described in detail with reference to the accompanying drawings.

As illustrated in the figure, the overall configuration of the present invention is a brown gas plant 10 for mass production of brown gas and brown gas supplied from the brown gas plant 10 to supply the center of the combustion chamber Combustion promotion burner 20 is configured.

The Brown Gas Plant 'Brown Gas Plant' (10) is a large capacity of brown gas production amount of 80,000 to 200,000 l / h, and a group of brown gas generators 'Brown Gas Generator' (1) is combined to form a group. It is connected to one Brown gas supply pipe for each group and integrated operation is performed by the integrated control method by the pressure control switch.

Essential considerations in the Brown gas plant (10) is an automatic water supply (5) for supplying supplemental water to several Brown gas generator (1), and a flashback prevention device for preventing the flame from backfire ( Only after the excretion of 9) will the stable production and supply of Brown Gas be achieved.

The present inventors have already commercialized and spread the flashback prevention device (Utility Model Registration No. 185304 and Patent Application No. 99-44793) for using Brown Gas, so that the Brown Gas plant of the present invention can be proposed.

The automatic water supply device 5 purifies the water stored in the water tank 2 by the water purifier 3, and then automatically supplies the brown gas generator 1 to each Brown gas generator 1 via the water pressure pump 4 via the pipe P. It is configured to be supplied.

In addition, the flashback arrestor 9 uses a flash back arrester 6 in the first stage, a second stage uses a frame modifier 7, and a third stage By supplying the compressed air by the compressor 'Air Compressor' (8) to increase the blowing speed of the brown gas, the brown gas nozzle tip 14 mounted on the end of the brown gas supply pipe 11 to be described later does not catch fire, And oxygen are introduced into the flame center of the combustion chamber 30 so that no backfire occurs and the brown gas can be continuously supplied.

As described above, the brown gas having stable supply of supplemental water and the backfire prevention by the brown gas plant 10 is supplied to the flame center of the combustion chamber 30 by the combustion promoting burner 20, and the overall configuration thereof is illustrated in FIG. 2. As shown in Figure 5, the center is provided with a brown gas supply pipe 11 is integrally equipped with a brown gas injection means 15 at the end, the outer side is compressed to the combustion chamber 30 by maintaining a constant gap A first air supply pipe 16 for supplying air and a fuel supply pipe 17 for supplying a heating source such as coal or bunker C oil to the combustion chamber 30 by an air transfer method are formed.
