As-fired coal separate bin metering system of coal conveying system

Abstract

The invention relates to an as-fired coal separate bin metering system of a coal conveying system. The as-fired coal separate bin metering system comprises added-to-bin amount data collection modules, a data communication module, a data processing module and a data display module. The added-to-bin amount data collection modules are arranged on all raw coal bins and used for collecting real-time coal addition amount information and accumulated coal addition amount information of each raw coal bin. The data communication module is connected with the added-to-bin amount data collection module and used for receiving the real-time coal addition amount information and the accumulated coal addition amount information which are conveyed by the data communication module. The data display module is connected with the data processing module and used for displaying current coal addition amount information and the accumulated coal addition amount information of all the raw coal bins. Compared with the prior art, the as-fired coal separate bin metering system has the advantages that the added-to-bin amount for mixed burning of each boiler is accurately reflected, and operation is convenient.

Description

technical field [0001] The invention relates to a coal conveying system, in particular to a coal conveying system into a coal bin metering system. Background technique [0002] Power plants are large coal-fired households. At present, there are many types of coal used in power plants. Each type of coal has a large difference in calorific value. In order to improve economic benefits, it is necessary to carry out blending and escalation. That is to add coals of different calorific values ​​(different types of coal) into the same coal bin, and mix and add bins in a certain proportion to meet the calorific value required for power generation, and at the same time meet various environmental protection requirements. Due to the price difference of coal types with different calorific value, the economic benefits brought by coal blending and siloing are considerable. However, if the mixing ratio is wrong when mixing coal and adding silos, it will directly affect the safe operation o...

AI Technical Summary

Problems solved by technology

The current fuel measurement method can only measure the total amount of coal added to the 20 raw coal bunkers of the four units within a certain period of time, and cannot accurately calculate the amount of coal added to the raw coal bunkers belonging to each unit within a certain period of time.

In this way, the analysis of the coal consumption of Rifa Electric Power Co., Ltd. and the research on the combustion index of a single boiler have brought a lot of difficulties, and it is impossible to accurately measure the economic benefits of each boiler, so as to achieve the purpose of saving energy and reducing consumption.
