Combustion energy-saving compound control device

Abstract

The invention relates to a combustion energy-saving compound control device which comprises a combustion optimal control system, a boiler and a fuel improvement adding system; the combustion optimal control system is connected with the boiler through a boiler connector module, the fuel improvement adding system is connected with the combustion optimal control system through a signal line and is connected with the boiler through a conveying line, and a control system, a data collecting system and an air preheating device are arranged in the boiler. By means of the combustion energy-saving compound control device, the aim of enabling the boiler combustion efficiency to be highest under the existing condition is achieved, and the boiler combustion efficiency can be improved by 2% to 5% through the full-automatic combustion optimization technology; and in addition, the fly ash amount and the fly ash carbon content are obviously reduced, and the heat efficiency of the limited scene can be higher than 5%.

Description

technical field [0001] The invention relates to a combustion energy-saving control system, in particular to a combustion energy-saving composite control device. Background technique [0002] Coal is the main energy source in our country. 84% of the coal in our country is used for direct combustion. Due to the relative backwardness of coal-fired equipment and combustion technology, it has brought about two major problems: low combustion efficiency and serious environmental pollution. Taking industrial boilers as an example, there are more than 520,000 coal-fired industrial boilers in my country, and the annual coal consumption accounts for 35% of the total coal production, but the average boiler efficiency is only 60%, which is 20 percentage points lower than the 80% efficiency of advanced countries. The above, and this alone, waste nearly 100 million tons of raw coal every year. The main reasons are: 1) Most industrial boilers are chain furnaces. The thermal efficiency of th...

Problems solved by technology

[0003] The present invention overcomes the deficiencies of the prior art, and proposes a composite control device for combustion and energy saving. The control system solves the problem of how to maximize the combustion efficiency of the boiler under the existing conditions—full-automatic combustion optimization technology can improve the thermal efficiency of the boiler 2 to 5%, and significantly reduce the amount of fly ash and fly ash carbon content, the thermal efficiency of the limited site can be higher than 5%
