Thermal power plant fuel analysis system and method

Abstract

The invention discloses a thermal power plant fuel analysis system. The system comprises a production information database, a boiler performance assessment module, a typical coal type database, a production cost assessment module, a resource database, a coupling module and a guidance module. The invention also discloses a method using the system for fuel analysis. The method is characterized in that with a guidance request of a client, matching stock coal type information or market coal type information in the resource database with a typical coal type in the typical coal type database, and sequencing stock coal types or market coal types according to the production cost, thereby screening the optimal combustion-purpose strategy by analysis. Under the precondition of big data analysis, the production cost of coal types is ordered, then according to the request of the client, the combustion-purpose guidance or the purchasing guidance of the coal type is provided, and two strategies of combustion and purchasing modes are adjusted, so that optimization of thermal power plant fuel scheduling is achieved.

Description

technical field [0001] The invention belongs to the field of production scheduling of thermal power plants, and more specifically relates to a fuel analysis system and method for thermal power plants. Background technique [0002] China is a country where coal is the main energy source, and coal resources occupy an important position in China's primary energy structure. In the composition of China's electric power industry, coal-based thermal power generation accounts for more than 80% of the total, and this structure will not change fundamentally for quite a long time. The coal type used in the design of boilers in thermal power plants is the design coal type, which is the best "suitable furnace" type of coal. [0003] However, China's coal resources are unevenly distributed, the coal washing rate is low, the price fluctuates greatly, the transportation pressure is heavy, and the supply situation of the coal market is becoming increasingly tense, making most of the thermal...

Problems solved by technology

[0004] However, for a long time, the fuel utilization, evaluation and optimization of power plants have remained at the experience stage, and technicians are usually selected based on experience during the long-term operation of the power plant. This method has low reliability and relies too much on the experience of technicians and technical level, it is difficult to quantitatively evaluate the value of coal
