The Desulfurization Process With Carbide Slag In CFB Boiler

There are so many mature technology of desulphuration. However, for some elecric power plant, it costs them a lot of money to support and operate the technique. So it needs an available technique which costs less investment and production cost to fit corporations which have their private characteristic. And its efficiency of desulphurisation is better than the other technic. The result certify something that we use carbide slag as desulfurizing agent. It fits for some factories which have steady material. Of course, the technological process is very suitable. And this is a success of environmental protection.The carbide slag has its good future. The article seek after better efficiency craftwork of carbide slag. We hope we can get the scheduled goal in the CFB boiler. We have necessary technological design of CFB boiler. After we throw carbide slag into the boiler, we get the appropriate Ca/S ratio and its influence for efficiency of boiler. Analyzing the outcome, we put forward the good Ca/S ratio is 2. 1 for high sulphur coal. At the same time, the data direct how to control the boiler.The essay, at first, introduces different harm about pollution from SO₂, as well as, the process and the influence are both recommended. In the light of vary desulphuration, we work out schemes for the reality.At second, the paper shows diversified desulphuration theories, process and action. From desulphurisation in coal to boiling and FGD, we sum up 14 desulphuration technique in common use. And we recommend them particularly. In the mean time, as emphases, we illuminate advantage and disadvantage in CFB boiler.At last, since we bring into effect the first project, the ending obtain goal. So we do not continue the next way. Furthermore we know the right Ca/S ratio. We conform to these capitals which contains fewer money, easier technics and superior desulphuration efficiency. The enterprise is very satisfied with the effect.
