Realization Of Coal Blending In Thermal Power Plant

Our country is based on coal as its main energy in the power industry, coal prices accounted for about 70% of the cost of thermal power generation companies, production and operation of thermal power plants in response to stress, to carry out coal-fired mixed to reduce production costs.According to the theory of steam coal blending, in accordance with Part quality characteristic index is linearly related to the argument, a reasonable choice of quality characteristic indicators as mixed coal range model constraints established mixed coal model, then combine Guangxi Liuzhou Power Generation Co. Ltd. Handling long path system, in the process of blended coal by coal mixed method, mixed in different locations, operating mode and choose the path of mixed coal costs caused by large differences in the actual situation, the original model was mixed coal supplement and perfect, considering the coal price factors and the process of blended coal cost factors, to create a new model of blended coal. By Liuzhou Power Generation Company Limited raw coal handling system, space, equipment, technology upgrading and transformation of coal-fired adding a catalyst, etc., and according to the characteristics of coal-fired mixed to create a new production process and operation mode, further applications different coal-fired mixed methods to achieve the coal-fired mixed. And coal-fired procurement reasonable choice of locations around the blended coal and mixed coal belt conveyor influence the process of transformation of the cost of the analysis and comparison of the last to use the new model for mixed coal fired mixed validate a new mix coal model can be mixed to achieve the minimum cost of coal. In this paper, coal handling system for the old coal-fired power plant will be mixed work to achieve the minimum cost of blended coal provides a new way of thinking, has a certain significance for the actual production.
