Abstract

The present invention is characterized by that a pipeline heat-efficiency on-line analysis and monitoring system is designed for steam power plant. Said system is mainly formed from data acquisition system, data base server, model operation server, and input / output equipment, and the steam power plant pipeline heat-efficiency counterbalance heat-efficiency calculation formula can e used in said system, so that its pipeline heat-efficiency and thermal less distribution can be calculated, and its analytical report or characteristic curve can be displayed on the information screen and customer's machine. Said system can implement on-line mointoring of working state of main pipeline system of steam power plant.

Description

technical field [0001] The invention belongs to the technical field of thermal power generation systems in thermal energy engineering, and relates to an online analysis and monitoring system for the thermal efficiency of pipelines in large thermal power plants. Background technique [0002] At present, there is still a large gap between the average coal consumption rate of thermal power units in my country and foreign advanced levels, about 60-70g standard coal / (kW·h), so there is a huge potential for energy saving. Taking a 1200MW thermal power plant (2×600MW units) as an example, it needs to consume nearly 10,000 tons of raw coal per day. Based on the annual average operating time of the unit of about 7000h, if the power supply standard coal consumption rate of the plant is reduced by 1g standard coal / (kW·h), It can save 8,400 tons of standard coal throughout the year. Calculated at the same year-on-year price, only fuel costs can save more than 4 million yuan per year; at...
