What are the advantages of a slime dryer with a boiling furnace as a heat source?
Nowadays, the use of slime dryers is increasing, and the raw materials that can be dried are quite extensive. The slime dryers produced by Hongzhi Machinery are widely used. The boiling furnaces as the heat source equipment for slime dryers also become dryers. Standard configuration. Some people may ask a lot of equipment that can do the heat source of the slime dryer. Why choose a boiling furnace? Let's take a closer look at the slime dryer boiling furnace.
The working principle of the boiling boiler is to crush the coal to a certain particle size, blow it with the wind, and burn in a boiling state at a certain height of the furnace. The combustion of coal in a boiling furnace is neither carried out on the grate nor in a space like a pulverized coal furnace, but is carried out on a bed of boiling furnace. The outstanding advantage of the boiling furnace is that it has wide adaptability to coal types and can burn bituminous coal, anthracite, lignite and coal gangue. Another benefit is that it burns the fuel sufficiently to increase fuel utilization. The average temperature of the boiling layer is generally 850 to 1050 ° C, the layer is very thick, which is equivalent to a large regenerator, in which the fuel only accounts for about 5%, and the newly added coal particles enter the layer and are several times higher than the temperature. The hot particles are mixed so that they can burn quickly, so coal gangue can be used instead. Production practice shows that the boiler runs normally with coal gangue containing up to 70% ash and a calorific value of only 7.54 MJ/kg. 40% to 50% of the heat can be received directly from the bed.
We chose the boiling furnace as the heat source for the slime dryer for the following reasons:
1. It has good adaptability to fuel and can burn almost all kinds of inferior fuels, such as coal grinding stone, stone coal, anthracite, oil shale, peat coal cinder. Foreign countries also use boiling furnaces to treat municipal waste and industrial skin residue.
2, labor intensity is small, welcomed by workers, and is conducive to automation.
3, less harmful substances in the exhaust, because boiling combustion is carried out at high temperatures, the amount of production is very small, when burning inferior high-sulfur coal, the use of limestone desulfurization is very convenient. The sulfur in the fuel is discharged in a solid state without causing contamination of SO2.
4. The combustion efficiency is high, and the combustion efficiency of the high-temperature flue gas boiling furnace that has been put into operation is over 95%.
5. The fuel preparation is simple, and the raw coal is slightly broken. It can be used for about 0-10mm.
6, flexible operation, good adjustment performance, the furnace heats up quickly. After the furnace is shut down, it can be operated at full load for two or twenty minutes, and the temporary fire start is faster.
7. Uniform temperature and stable heat supply are beneficial to the improvement of product output and quality.
