DZS、SZS series environmental-friendly water-coal-slurry boilers
DZS、SZS series environmental-friendly water-coal-slurry boilers adopt mature circulating fluidized bed (CFB) boiler automatic control system and environmental friendly combustion technology to use coal as one of the main fuels. This boiler combines the advantages of circulating fluidized bed technology and water-coal-slurry combustion technology to design a water-coal-slurry combustion boiler that can adapt to the characteristics of coal in large combustion capacity and high combustion efficiency.
The water-coal-slurry of this boiler is produced by the mutual shearing force generated by the movement of particles and the liquid in a high-speed mixer. The large-size fuel in the slurry fuel can be fully atomized and burned under the combustion furnace, which has become the current circulating fluidized bed (CFB) boiler does not have the competitive weapon of the burning large particles of fuel. Due to the excellent technology of the combustion of coal in the water-coal-slurry, the combustion efficiency can reach above 97%, which is much higher than the traditional boiler technology. Therefore, this series of water-coal-slurry boilers can effectively reduce the consumption of coal and other combustibles, and for a certain range of the burning of various kinds of coal, it can reach the best combustion effect.
The water-coal-slurry combustion technology of this boiler adopts a secondary partitioning method. The secondary partitioning arrangement can make the residence time of coal particles in the furnace more reasonably, and the combustion rate of coal can be effectively improved while reducing the emission concentration of harmful gases such as nitrogen oxides and sulfur dioxide. The water-coal-slurry technology of the boiler is further improved, and the boiler structure is also continuously optimized. The refractory lining of the boiler is made of alumina brick and special ceramic brick for multiple times, so that the life of the boiler can be effectively improved.
In short, the DZS、SZS series environmental-friendly water-coal-slurry boilers have the advantages of high efficiency, low emission, safety and environmental protection, and can effectively provide the corresponding connection device to the boiler. This series of boilers are suitable for low calorific value pure coal, meagre coal and slurry fuel applications. It can provide a variety of industries such as electric power, petrochemical, coking, textile, printing and dyeing, pharmaceutical, papermaking with low cost and low pollutant emission. Reliable thermal energy support.
