JT-R Type Coal Saving Agent
1. Product Features
The products are liquid and powder, which are packaged in 250kg and 25kg barrels.
Density: (20℃)1.08-1.12(g/cm3)
P H: (20℃) 11.8-12.5
Solid content: 22.0-23.0 (%)
Suitable dosage: 0.08-0.12 (%)
2. Scope and performance
Mainly suitable for all kinds of lignite, bituminous coal, anthracite and coke, and can be used in various pulverized coal injection boilers, chain furnaces, kilns and other coal-fired equipment, especially for calorific values of 4000-5000 (kcal/kg coal) The effect of low calorific value coal with high ash content is more obvious.
This product can significantly reduce the concentration of exhaust smoke and reduce the carbon content in the kiln slag to about 20% of the original carbon content. This product is easy to use, non-volatile, and has no natural loss when added to coal. Under normal circumstances, users can save coal by 4.6-9.9%.

4. Characteristics of coal agent in this section
1. This product has permeability, catalytic effect, sulfur fixation effect and cleaning effect;
2. This product can reduce the ignition point of coal, promote the full combustion of volatile matter, reduce the generation of black smoke, and increase the burnout rate of carbon inside the coal with larger particle size;
3. On the premise of not affecting the quality of cement clinker, make the thermal condition in the cement kiln more reasonable, and increase the secondary and tertiary air temperature by more than 50℃;
4. On the premise of normal operation of the boiler, it can save more than 5% of coal;
5. This product does not contain any components that can damage coal-fired equipment, and does not affect the safety of coal-fired equipment;
6. The use of this product in a cement rotary kiln can increase the effective length of the firing zone, will not cause a local increase in the flame temperature, will not damage the kiln skin, and can reduce the production of NOX;
7. In industrial boilers and civil coal furnaces, this product has certain sulfur-fixing and anti-coking effects, SO2 in flue gas is significantly reduced, carbon content in slag or coal ash is reduced, and slag discharge is reduced;
8. The ratio of adding this product is: coal: water: coal saving agent = 1000: 10: (0.8— 1.2) or the best addition amount is determined by experiment.
5. How to join when using:
1. When used in cement plants, it is generally added directly by pumping, as shown in the following diagram:
The company provides information on manufacturers of metering devices.
The detection and control method of the feeding amount: According to the output of the rotary kiln and the amount of the coal saving agent added, calculate the quality of the coal saving agent that should be added per minute, and use a measuring cylinder with a range of 1000ml to randomly inject the coal saving agent into the kiln from the preparation. The nozzle of the coal agent is connected, and the time is 1 minute, and the quality of the connected coal saving agent is weighed. When the feeding amount is inconsistent with the calculated amount, the speed of the metering pump should be fine-tuned until it meets the specified requirements.
2. When used in boilers and other coal-fired equipment, it is only necessary to install nozzles above the conveyor belt or coal hopper.
6. Precautions
1. This product should be used after passing the inspection. The acceptance method is as follows: Density measurement shall be carried out according to the provisions of GB/T611-2006; take two pieces of filter paper with a diameter of 110mm, immerse one of them into the product, depth 10mm, time 3s, take out After drying, ignite two pieces of filter paper at the same time, and blow them out at the same time after burning for 2s. Observe that the filter paper immersed in this product will continue to burn, which is qualified;
2. When handling and storing this product, it should be prevented from being dropped, smashed, squeezed by external force and approaching high temperature, and the stacking height should not exceed two barrels;
3. Before use, check the company's logo and then open the cover to confirm that the product and model are correct before use;
4. This product is slightly irritating to the skin. After contact with the skin, it can be washed with water and cannot be eaten by mouth;
