Description

Makeup {CREMATION FURNACE}

The present invention relates to a makeup furnace capable of treating an odorless, lead-free environmentally friendly makeup by inducing complete combustion through a reheat burner after main burner.

Generally, in order to remove the problem of air pollution and odor caused by exhaust gas generated during combustion, in addition to the primary combustion by the main combustion furnace, a reheating furnace is provided as a next step, To induce complete combustion and to achieve completely odorless and smokeless (smokeless).

The makeup furnace, which is the background of the invention, is formed to have a size capable of accommodating the entire tube inside thereof, and has a plurality of combustion chambers for forming a long flue length.

However, since only the refractory bricks are used so as to utilize thermal heat efficiently in the main combustion furnace and the reheating furnace of the conventional make-up furnace, or the refractory material mixed with the refractory brick and the ceramic material, i.e., a heterogeneous refractory material is used, And it is disadvantageous in that it is inconvenient in construction because of the increase in the weight of the small size and the reheating area itself and maintenance is inconvenient.

In addition, when damage to the refractory brick itself occurs in the main combustion furnace or the re-burning furnace through long-term operation, it is required to replace the main combustion furnace with the main combustion furnace or the refinery itself. In other words, It is required to have an economical refractory which is optimized for production and maintenance because it costs tens of thousands of won per annum for digestion.

Particularly, in the case of the reheat furnace, heat storage is not required, the function of re-burning the combustion gas burned in the main combustion furnace is firstly demonstrated, and it is possible to withstand the thermal shock generated at this time or to buffer the thermal shock, There is a need for a technique capable of partially replacing only a portion in contact with a flame due to expansion and contraction of the flame.

Korean Patent No. 10-0205565 (Apr. 02, 1999) Korean Patent No. 10-0523322 (October 14, 2005)

It is an object of the present invention to provide a refractory material which does not have refractory bricks used in a main combustion furnace and which is a wall of a re-combustion chamber containing ceramic fibers, To provide a makeup furnace that is easy to manufacture and maintain because it is possible to reduce the weight of the reheat burner relative to the weight of the main burner.

According to an aspect of the present invention, there is provided a fire extinguishing system, comprising: a heat insulating board disposed on an inner surface of a frame; a fire extinguishing chamber having refractory bricks formed on an inner surface of the heat insulating board; An inner flue connected through the main combustion chamber; And a re-combustion chamber located at an upper portion of the main combustion chamber so as to penetrate the inner combustion chamber, wherein the re-burning chamber comprises: a second frame disposed on the one frame and corresponding to the one frame; There is provided a makeup furnace characterized in that the other side laminated portion of the ceramic fiber material disposed on the side surface is provided.

The other laminated portion may have a lamination thickness corresponding to a total thickness of the heat insulating board, the refractory brick, and the one laminated portion of the main combustion chamber.

The other side laminated portion has at least one layer made of a homogeneous refractory material stacked along the wall thickness direction or the ceiling thickness direction of the re-burning chamber, and the first layer located on the inner space side of the re- ; A second layer laminated to the first layer toward the outside of the re-burning chamber and having a thickness corresponding to the first layer; And a third layer having a relatively thicker layer thickness than the first layer or the second layer and stacked between the second layer and the other frame.

Further, the main combustion chamber may include a refractory door provided on a front wall of the main combustion chamber; A main burner provided in a rear wall of the main combustion chamber; A main blowing port provided on the rear wall above the main burner; And a rail for a refractory bogie installed at the bottom of the main combustion chamber, wherein the main tuyere is inclined toward a flame generated from the main burner.

The re-burning chamber may further include a vortexable coating wall installed inside the re-burning chamber to partition the first space in which the inner flue is located and the second space opposite to the inner flue.

The coating layer may further include a coating layer positioned on the inner surface of the one side lamination portion or the other side lamination portion.

In addition, the main combustion chamber and the re-combustion chamber may be connected to each other by a coupling means with a compressed ceramic fiber interposed therebetween.

The main combustion chamber and the rechargeable combustion chamber may further include a reinforcement frame connected to the outer surface of the main combustion chamber and the rechargeable chamber.

According to the makeup furnace according to one aspect of the present invention, since the refractory material for re-combustion is made of ceramic fiber material alone, the refractory brick is mainly used, or lightweight compared to the conventional main furnace using refractory bricks and ceramic fiber It is possible to manufacture a rechargeable rechargeable battery which can be partially replaced, so that problems such as non-economic problems in manufacturing and maintenance, and replacement of refractory bricks due to refractory brick damage, . For example, the time and cost for replacing only the first layer or the first fold made of ceramic fiber can be relatively short or small compared to a refractory brick replacement period (e.g., one month or longer).

Further, even if the high temperature or thermal shock caused by the internal flame of the re-burning loss damages the first layer of the re-burning chamber, only the first layer is separated and replaced in the second layer, thereby providing a furnace with excellent economy.

Since the refractory brick is not provided with the refractory brick itself, it can be free from the problem caused by the refractory brick damage, and the rechargeable burnout can be lightened, which can be very advantageous in the production economy.

Further, when only the ceramic fiber which is a refractory material of the same quality is used in constructing the refractory material for re-ignition loss, the expansion and contraction of the refractory material composed of the refractory brick and the ceramic fiber can be relatively evenly performed, There is an advantage that the development can be prevented in advance.

Further, a coating layer is further provided on one side laminate portion of the main burner chamber or on the other side laminate portion of the reheat burner chamber, which is advantageous in prolonging the replacement life of the ceramic fiber material.

Further, since a compression ceramic fiber is interposed between the main combustion chamber and the re-burning chamber which are stacked vertically, and the main combustion chamber and the re-combustion chamber are coupled to each other by a plurality of bolts and nuts, And it is possible to realize a perfect airtightness between the main combustion chamber and the re-combustion chamber.

In addition, the rail for the refractory bogie of the main burning ladder may include a sloped section where a portion is inclined, so that the refractory bogie can be stably positioned inside the main burner chamber.
