N' residue usually contains hydrocarbons such as methane and ethylene, hydrogen, water, tar, crude light oil, ammonia, heat, carbon dioxide, coal powder, etc. , when the temperature is 500'c'1nia, h, some of the hydrocarbons in the gas are excited by the heat hγ and become carbon, and this carbon adheres to the furnace wall and the inner surface of the gas pipe and grows. , and the temperature of the gas is 500 to 300
℃, the tar imitating the gas will actively condense and thermally decompose, and this tar will adhere to the inner surface of the gas pipe and grow rapidly. If this happens, the pressure loss of the gas flowing through the gas conduit will increase7, eventually clogging the inside of the conduit and making it impossible to operate. Therefore, in order to prevent such troubles, in the past, the first step of the coal carbonization furnace was
In addition, if a cyclone is connected to the coal carbonization furnace, a water sprinkling device is installed at the outlet of the cyclone, and the coal carbonization gas is heated to below 100°C by water sprinkling, and the cyclone contained in the gas is This was done to prevent the growth of solid water deposits on the inner surface of the conduit by washing away the suspected C particles that were present in the pipe. That will happen.

が中断されることになる。(11 gasification furnaces were installed, and this was connected to a coal carbonization furnace.
The coal carbonization gas is introduced into the gasification furnace and oxygen is supplied to partially harden the coal carbonization gas, and - high rust 1 reducing gas containing carbon oxide and hydrogen as main components is supplied. Method 1: (5) Install a coal preheater, connect it to a coal carbonization furnace through a barrel, and use the coal carbonization gas to reduce the coal carbonation gas. A method for reducing the amount of heat consumed by a coal carbonization furnace by introducing a preheater (・) and supplying coal for carbonization to dry and preheat the coal. ■According to a series of methods, the Although heat can be recovered, there is a problem in that the above-mentioned dangerous substances adhere to and accumulate on the inner surface of the gas pipe connecting the coal carbonization furnace and the coal carbonization gas utilization equipment, causing operational problems. 2 In order to solve this problem, high-temperature gas at a temperature of 500 to 700°C with an oxygen concentration adjusted to 5 to IO% is blown into the conduit filled with Ai+ deposits. The deposits are burned while controlling the oxygen concentration and gas temperature so as not to cause local heating, and the deposits are taken out of the system as yc combustion gas along with the unburned matter separated by spalling. All you need to do is caulking 3
゜However, in order to perform such a decoking process, it is necessary to cut off the power to the l/lI' flow of coal carbonized gas in the gas pipe, and the operation of the above-mentioned coal carbonized gas utilization equipment is interrupted. It turns out.

となる問題もある。Therefore, two systems of gas pipes were installed, and coal carbonization gas was passed through one of the pipes, and the other system was used as a backup. Continuous operation is possible by switching the flow of gas to the backup pipe and decoking the pipe where deposits have formed. Condition <(
Since the temperature of the conduit is 100 p, the temperature of the conduit must be raised to a predetermined temperature before gas is allowed to flow through it. Therefore, even if it is necessary to switch the gas in an emergency because it takes a lot of time to do this, we can handle this situation.
There is also an arrow, 1.1.1, that consumes a lot of heat to raise the temperature.
Another problem is that a large space is required to install two systems of gas pipes.
