Embodiment Construction

[0041]After the market selects and orders coal that is suitable for the coal blending requirements of thermal power plants, it passes through 2. the conveyor belt, passes through 8. the belt scale checks the weight; passes through 2. the conveyor belt, enters 9. the online full element analyzer; passes through 2. the conveyor belt, puts various Coal blending is transported to each 1. Coal storage bunker. During the process of transporting coal from coal blending to 1. Coal storage bin, 8. The belt scale checks the weight. 9. The online full-element analyzer will real-time analyze the weight of the various coals flowing through and their moisture, ash, and volatilization during this process. Minutes, calorific value, sulfur, hydrocarbon, nitrogen, ash melting point content and technical indicators are transmitted to the computer through the 4. communication line, and are recorded and stored one by one, so as to provide the original content parameters of each coal element for the...

Abstract

The invention discloses a high-efficiency precise coal distributing system. The high-efficiency precise coal distributing system is applied to provide various coal technical indicators required by a coal-fired boiler in a power generation process of a thermal power plant system, a detection control process for distributing coal before combusting various types of coal which are mixed and combusted in proportion, and the power generation and coal proportion monitoring control process in a power generation process, wherein the calculated parameters meet the standard or are close to the standard.

Description

Technical field: [0001] The present invention is applied in the power generation process of the thermal power plant system to meet various coal-fired technical indicators required by coal-fired boilers. It is necessary to mix various coals together in proportion and the combustion calculation parameters reach the standard or approach the standard. An efficient and accurate coal blending system for the detection and control process of coal blending before combustion and the monitoring and control process of the power generation and coal ratio monitoring and control process during the power generation process. Background technique: [0002] Coal, which accounts for 70% of the cost of thermal power generation, requires high heat, complete combustion, less ash and ash, and can effectively use heat, which is the real quality requirement of coal for power generation companies. [0003] The power generation boiler is designed and arranged according to the coal type and coal quality...
