1. Product technology
This product is our company and the Chinese academy of sciences, the scientific research institutions cooperation projects. Many research institutes of integrating scientific research, advanced technology, and choose the environmental molding qinshui coalfield center and large adding plant quality of foam as raw materials, mixing proportion of binder, solid sulfur chemical additive agent into flat type carbon block.
2. Product advantage
(1)coal can eplace coal chemical industry applies fertilizer, gasification furnace, improved the availability and adding value, ferro silicon fine anthracite altemative coke in metallurgical special use, such as gasification improved the availability and value-added focal foam, promote the integration of resources, coal industry process of adjustment of product structure.
(2)the surface is big, easy combustion, thoroughly solved the problem, not lump of residual over cinders, and slagging burning coal directly, compared with more than 10% of coal boiler efficiency, improve more than 20%, chemical, chemical industry, metallurgy industry etc. Use coke users is an important way to reduce costs.
(3)and in transportation and burning process, Can reduce dust emissions 74-86 percent, smoke, dust, solid sulfur, reduce the pollution of the atmospheric environment, improve the working environment, promote the environmental protection.
3. Features
Coal gasification with uniform particles, good air permeability, fire, burning full, high thermal efficiency, low sulfur method, thermal stability and mechanical strength, and has certain waterproof effect.
4.Product usage
Can be used in industrial boiler, kiln, gasification, metallurgy, electric alloy carbon and civil cooking food, heating furnace, etc.
