Coking furnace

Abstract

The invention discloses a coking furnace which is safe, environment-friendly and stable, is suitable for continuous scale production, and is used for clean burning operation of coal in the clean coal industry. The coking furnace consists of air inlets 2 and 5 of a C-shaped elbow pipe of between 45 and 90 degrees, air inlet pipes 1 and 6, air chambers 3 and 4, a circulating water cooling layer 7 and a combustion chamber 8, wherein the air inlet pipes 1 and 6 are straight pipes with the diameter of between 30 and 70mm, pass through the circulating water cooling layer 7, and are communicated with the combustion chamber 8 and the upper and lower air chambers 4 and 3; in the air chambers 3 and 4, the air inlets 2 and 5 of the C-shaped elbow pipes of between 45 and 90 degrees having the same diameter as that of the air inlet pipes 1 and 6 are firmly welded with the air inlet pipes 1 and 6 respectively; air is supplied to the combustion chamber 8 by an upper exhaust pipe and a lower exhaust pipe at two sides; and air entering an air supply chamber can smoothly flow into the air inlets of the C-shaped elbow pipe of between 45 and 90 degrees, and flows into the furnace chamber of a combustion furnace through the air inlet pipes. The air inlets of the C-shaped elbow pipe ensure small wind power consumption, the air quantity entering the furnace chamber is uniform, and raw coal in the furnace is combusted uniformly, so the produced semi-coke has stable quality, the production efficiency is high, and energy and resources are saved.

Description

1. Technical field [0001] The invention relates to a coking furnace, which is mainly used for burning raw coal into semi-coke and separating semi-coke oven gas and coal tar from it. It is a safe, energy-saving, environmentally friendly and efficient furnace type, suitable for stable large-scale continuous production of semi-coke . 2. Background technology [0002] In the current existing technology, the traditional coking furnace is mainly composed of a water tank, a semi-coke scraper assembly and a semi-coke drying device, a push-out charcoal assembly, a furnace body, an air inlet pipe, a circulating water cooling layer, heat insulating materials, refractory bricks, It is composed of coal inlet, coal distribution hopper, raw coal conveyor belt and semi-coal conveyor belt, air supply system, gas and coal tar recovery and separation system, etc. The raw coal is transported by the conveyor belt to the coal distribution scuttle on the top of the furnace, and the coal distribut...

AI Technical Summary

Problems solved by technology

The disadvantages of this kind of semi-coke furnace: First, the level of the air inlet pipe is easy to block and sinter with coal, so that the wind cannot enter the combustion chamber

The second is that the wind supplied into the combustion chamber cannot enter the furnace cavity smoothly, resulting in a large loss of wind power

The third is that the air volume entering the furnace cavity is very uneven, resulting in uneven combustion on both sides of the furnace. The part with a large air supply volume has a high temperature and there is over-burning phenomenon; Phenomenon, directly causing waste of raw coal resources
