Si3N4 bonded SiC(N-SiC) nozzle is mainly used in Fuel Gas Desulfurization (FGD) system.  As one component of FGD system, the nozzle can spray out lime slurry in certain angle, flow-rate and granularity, for the slurry to completely react with gases such as SO2, NO2, HF, which comes from burning boiler. After FGD reaction, the generated plaster can be recycled for construction, while the clean gas will be discharged to atmosphere. It is for environmental protection.

Applications
flue gas desulfurization- environmental protection in coal power and other coal-fired fields.

Features And Advantages

1. It has good performance of abrasion resistance, and long life-time, corrosion resistance. The working hours can reach 80,000-100,000 h.

2. It is featured with reasonable granularity, angle, and flow-rate. It can be customized, to meet customer’s requirement, and the performance is reliable.

3. It is designed in easy to install, simple structure and maintain.

Si3N4 bonded SiC is a new type of high-grade refractory materials. It includes radiant tube, brick, deformed parts and so on. These products, which have energy saving, environmental protection, high temperature resistance, corrosion resistance and other advantages, can be widely applied in the field of Urban construction, Kiln Furniture, Steel and non-ferrous mental, chemical construction materials, etc.

Si3N4 bonded SiC products with high strength in normal temperature. Under 1200-1400℃, it can keeps almost same strength and hardness with it under normal temperature. As the environment is different, the maximum service temperature can reached up to 1650-1750℃.

These products are obtained by reaction sintering of a mix of SiC with Si fines and additives and nitridation in N2 atmosphere at~1450℃

The following reaction would take place:

3Si+2N2→Si3N4

3Si+SiO2+2N2→2Si2N2O

Si3N4+SiO2→2Si2N2O

Si3N4  Si2N2O act as binder for the SiC grains
