Sand drying roaster feed mode: positive feed: All fuel boiling layer at high temperatures, is conducive to fine fuel burn, which can reduce the ash away losses. But the inlet must be sealed tight, and the new fuel is easy to accumulate in the feed mouth. Positive feed generally use mechanical feed device, such as a spiral coal machines. Since the inlet temperature in the positive zone, so the spiral to the poor working conditions of coal. To simplify the feeding mechanism, and improve its operational reliability, currently used in place of a spiral tube slide coal stoker. Slipped to 50 ° above the coal pipe inclination ramp into the positive zone furnace, relying on coal pillar inner tube pressure fuel is injected directly into the furnace. To prevent flame from the inlet, smoke, balance pipe in the furnace wall mounted boiling furnace slag technology to slip coal pipe and furnace pressure area connectivity. When a good seal or not to install coal balance pipe. Negative feed: negative and positive feed contrary specializing in the production of feed boiling furnace slag, since the fuel from boiling over into the slag layer boiling furnace ignition, therefore, there are some fine without boiling layer of fuel was increased flue gas stream away , increasing the fly ash heat loss. Into the negative zone in the coal feeding device is relatively simple, reliable, and the Department of free fall, so the spread of large, easy to cause the discharge port stacker. Boiling furnace boiler for a particular industry, mainly for the use of pyrite in the processing of the ore particle size of 3-0 mm. Under normal circumstances, generally speaking, its operation is very simple and relatively safe, but if it is new or boiling furnace operation is not the time accidents often occur, leading to accidents. In particular the new roaster furnace slag boiling in the design, must be repeatedly tested for the construction, it is as if boiling in the production of the furnace is not smooth driving situation will affect the overall production, causing direct economic losses. Boiling furnace slag, the best boiling furnace slag, Sheng Yu Sheng Yu machinery provided by the machinery. This information consists of: providing Xinxiang Yu Sheng Machinery Co., Ltd.
